Avoiding wear on boiler feed pumps

Pumps as turbines in water industryRunning pumps as turbines has become an efficient method

of generating power as well as recovering energy, and as

Bryan Orchard discovers, pumps are less complicated to operate

than turbines.

Improving open canned systemsThe results of a study on the hydraulic performance of open-

bottom canned pump intakes should help reduce velocity

fluctuations and undesirable flow rotation, says David Sanders.

Blade adjustment cuts energy costsGerd Witte and Dr Manfred Stollenwerk examine how cooling

water pumps with an adjustable pitch angle of propeller blades

can lead to cost savings in power plants.

Keeping track of bearing wearEffective monitoring of thrust bearing wear is a crucial factor in

preventing pump and impeller damage. Sensonics’ Russell King

describes how the technology can be successfully implemented.

Applying NPSH to metering pumpsNPSH calculations are used to establish if centrifugal

pumps will operate satisfactorily in a given process. However,

extending the concept to metering pumps can be difficult, as

Patrick Deniau explains.

WORLD PUMPS TEAM

EditorialWelcome to the August issue of World Pumps

Our features this month begin with a look at the use of pumps as turbines in the water industry. Running centrifugal pumps in reverse rotation mode has been exploited to a limited degree as a means of generating power in locations where it is considered too expensive to purchase a hydro turbine. Nowadays, running pumps as turbines (PaTs) has become seen by some operators of small hydropower plants and pump manufacturers as an efficient method of generating power as well as recovering energy and contributing to savings. There is the added benefit that pumps are less complicated to operate than turbines.

‘Improving open canned systems’ discusses how the results of a study on the hydraulic performance of open-bottom canned pump intakes can aid engineers and pump users to design these systems with reduced velocity fluctuations and undesirable flow rotation.

Design improvements are also at the core of the next article ‘Blade adjustment cuts energy costs’. Once again, it shows that detailed design improvements can pay great dividends when it comes to energy savings. This article explains how power plants can save energy by using cooling water pumps with an adjustable pitch angle of propeller to change the flow rate.

However, good design is one thing, but keeping what you have going is a full time job for many pump engineers. ‘Keeping track of bearing wear’ argues that effective monitoring of thrust bearing wear is a crucial factor in preventing pump and impeller damage. This article describes the techniques available for monitoring thrust bearings on boiler feed equipment and explains how the technology can be successfully implemented and commissioned.

Finally, in ‘Applying NPSH to metering pumps’, we look at how net positive suction head calculations are routinely used to establish whether centrifugal pumps will operate satisfactorily in a given process.

Mono NOV has added to its TR

Muncher range. The new model

has been especially designed to

protect downstream equipment

from blockages, meeting

discharge requirements in

sludge/fat processing. “Down-

stream process requirements

have changed due to the

increasing installation of finer

inlet screens, resulting in reduced

particles and solids loading

within the sludge treatment

process,” said Ian Hallows,

business manager for Waste-Tec

products at Mono.

The Muncher features a trash

trap, inclined cutter stack and

pull-back design. The cutters can

be specified to either 8.0 mm,

5.5 mm and 3.0 mm thickness to

match particle size.

Pressure boosting helps fire-fighting KSB has launched two automatic

package pressure boosting units

for fire-fighting systems.

The Hya-Solo D FL single-pump

unit and the Hya-Duo D FL

dual-pump units have been

designed for use in residential

buildings as well as on commer-

cial and industrial premises. Their

maximum flow rate is 110 m3 per

hour, to a head of up to 160 m.

The Hya-Duo D FL dual-pump

unit features a stand-by pump

and separate electric circuits. The

units are started up and switched

off as a function of pressure and

can be controlled via one or

several remote ON-OFF limit

switches at a wall hydrant.

The discharge and suction side

of the pump are each

equipped with a lockable valve

which prevents any unauthor-

ised person from closing the

valves and thus stopping the

unit.

The pressure switches and limit

switches are monitored for

broken wires and short circuit

to make sure the pressure is

maintained and the unit is

always ready for fire-fighting.

Both units meet the criteria of

the new DIN 14462 standard for

fire-fighting water systems, which

is valid since April 2009.

Addition to magnetic drive rangeAnother non-metallic magneti-

cally driven gear pump has

been added by Pulsafeeder Inc

to its Eclipse range.

The Eclipse 125 has a wider

drive gear, idler gear, and liner,

making it easier to increase flow

without overspeeding the

pump. It is made of engineered

fluoropolymer, carbon graphite,

and graphite impregnated

silicon carbide bearings making

it suitable for corrosive fluid

applications.

The non-metallic gear pump

has only 16 parts that are self

aligning and allow for easy

maintenance and ease in

ordering, the company says. The

pump can be entirely serviced

from the front and leakage is

reduced. Its universal motor

adaptors can mate up to

multiple NEMA and IEC motors

while the universal flanges mate

to both ANSI and DIN flange

connectors.

BadgerMeter has developed a

compact aseptic control valve

suitable for use in bioreactors,

pharmaceuticals, biologics and

food processing. The Series

SCV-09 is a modulating

diaphragm style valve which

meets the manufacturing

standards established by the 3A

Sanitary Standards.

The diaphragm valve uses a

patented sealing arrangement

which avoids the metal-to-metal

contact which could result in

metal particles being released

into sensitive products, while

giving a similar level of control to

a metal plug and seat.

The self-draining, isolated seal

design enables the valve to be

used in applications where quick

assembly and disassembly for

effective cleaning is essential,

such as clean-in-place (CIP) and

sanitize-in-place (SIP) processes.

2000 bar/29,000 psi and is

suitable for tough use in difficult

conditions. It offers durability and

reliability when working in wet,

windy, remote and harsh

environment and is IP56

protected, the company says.

The electric pump is built

around a steel frame with an

integral swivel lifting point. The

frame has been balanced to

keep vibration to a minimum. It

features a full pendant control

interface with a simple digital

pressure read out. High oil flow

ensures the pump reaches the

desired operating pressure very

quickly.

The pump offers on board

diagnostics, high and low

pressure filtration with

in-built sensors and a

high-pressure quick

connect port. The user

can select the

KD Scientific.

The Gemini 88 pump can infuse

simultaneously at different rates,

or infuse with one syringe and

withdraw with the other. When

combined with a valve box, the

Model 88 can provide continuous

delivery, the company says.

The Gemini 88 is designed for

continuous operation 24/7 with a

range of syringes from 0.5 μl up

to 140 ml.

The pump has high pressure

capabilities and TTL and RS-232

interfaces for data acquisition and

control. The communications

ports enable daisy-chaining up to

100 pumps.

Current diversion ring helps VFDsInpro/Seal Company has developed current

diversion ring (CDR) technology for motors

using variable frequency drives (VFDs) to

adjust the speed output of alternating

current (AC) motors.

According to the company, VFD-controlled

motors can produce destructive shaft

currents that must be redirected around the

bearings, otherwise they can be destroyed.

Inpro/Seal’s CDR safely diverts these currents

and saves the motor bearings.

The CDR components are made from

corrosion resistant bronze in any shape or

configuration required, and are available as a

‘press-in,’ a ‘clip-on,’ a ‘split’ configuration or

an ‘MGS’ design, which prevents contamina-

tion from entering the motor bearing

enclosure while diverting destructive shaft

currents.

Anti-clog technology for impellersITT has introduced anti-clog

impeller technology for its small

N-series of wastewater pumps.

The Flygt N-3085 impeller moves

axially to improve flow and help

eliminating clogging under

difficult of conditions. When

detritus enters the volute, the

patented N-hydraulic pushes

them from the centre to the

perimeter of the inlet. Moving

axially also enables very large

detritus to get through. The

impeller design is coupled to a

specially developed relief groove

and is self-cleaning.

ITT says that the new impeller

significantly improves the

anti-clog characteristics of the

company’s Flygt N series of

pumps. “This is a giant step in

the development of our N-range

for wastewater pumping,” says Ulf

Arbeus, R&D Director of ITT Water

& Wastewater.

Diaphragm design lengthens lifeFlotronic Pumps has developed a

new diaphragm design for its

range of air-operated double

diaphragm pumps that could

help the diaphragm last longer.

Currently, the diaphragms in the

pumps feature an ‘inside out’

concept that enables fluid to

pass between the diaphragms

directly through the pump centre

with air pressure operating on

the outside. The pump is held

together with one nut situated

on the opposite side of the

pump from the external air valve.

After review, a ‘mid-shape’

diaphragm design was conceived

which has proved to be longer

lasting than traditional diaphragms

because the revised shape results

in less stress. It is also easier to fit

than its predecessors.

new pump sizes for its ranges of

vertical in-line (VIL) and end

suction pumps.

Armstrong now offers a 20×20

×19 m pump for the 4300 Vertical

In-Line (VIL) Series, now the largest

in the range, which is designed for

large central plants and district

cooling facilities around the world.

The company has also launched

a 3×3×5 m pump for the Series

4280 end suction and Series 4380

VIL pumps.

The small units are suitable for

use in low head re-circulation

systems that are specified for

small chillers, boilers and cooling

towers. They can also be used in

low-head applications such as

greenhouses and small

commercial projects.

A line of vertical centrifugal

pumps suitable for use with

aggressive, heated and contami-

nated fluids has been developed

by Friatec. The GVSO series of

pumps has been developed from

the company’s GVSN Series of

vertical pumps, the company says.

While the GVSN pumps are

typically used for pumping

sulphuric acids, liquid sulphur, tar

and molten salts, the GVSO pump

can be used being used to address

new applications in the solar

power generation industry. These

applications use molten salts with

temperatures up to 560° C. The

molten salt is used to help the

transfer and storage of the heat.

Friatec says that is has already

successfully tested its new GVSO

pumps for several solar plants

throughout Europe. The GVSO

submersible pumps, which are

suitable for aggressive fluids in

high temperatures are made from

high-grade stainless steels with a

medium lubricated sleeve

bearing concept.

Mono NOV and Water For All, an

African non-governmental

organisation, have developed the

‘Fun Pump’, a water system made

up of an electric pump powered

by a solar panel and a children’s

merry-go-round. The electricity

generated from both the power

of the sun and the merry-go-

round provides a significant

increase in water production over

manually operated pumps, the

organisations say.

“The strength of the Water For All

programme combined with our

proven technologies and wide

distributor network across Africa

will allow us to bring clean water

to thousands of communities and

make lasting changes in the health

and well-being of children,” said

Paul Naylon, GROUP MD of Mono.

Depending on the depth and

yield of the borehole, the Fun

Pump’s solar panel can produce a

minimum of 5,000 litres of water

per day. When the merry-go-

round is in use, production

increases by approximately 20%.

The system also comes with a

pump, a 160 Watt solar panel,

generator, storage tank and tap.

In addition to the Fun Pump,

Mono and Water For All have also

worked together to develop the

Sun Pump, a 480 Watt solar pump

that is capable of producing

8,000-30,000 l of water a day

based on the specifications of the

borehole. The Sun Pump comes

with several pump options,

allowing it to work in a variety of

settings and depths.

‘Super-tough’ rotating unitseepex’s MDP series of progres-

sive cavity metering pumps now

features a rotating unit made

from Xytel ST801, said by the

company to be a ‘super tough’

nylon which is virtually unbreak-

able, is more resistant to abrasion

than stainless steel, and runs at

low speeds and under high

pressure.

While conventional progressive

cavity pumps generally have a

rotating unit consisting of ten

individual parts, the rotating unit

in the MDP series is injection

moulded as a single piece, which

is less expensive than conven-

tional units, easier to maintain,

and much faster to replace,

seepex says.

The new MDP progressive cavity

metering pumps provide pulse-

free metering of low- to

medium-viscosity fluids with

repeatable accuracy up to ±1.0%.

The pumps are available in four

sizes with capacities from 0.1 to

580 l/h (2.5 gpm) and pressures

to 12 bar (174 psi).

Pumps featuring the Xytel ST801

rotating unit are suitable for

industrial wastewater, flocculants

and other water-based chemical

solutions, emulsions or slurries.

seepex says that they are not

recommended for use with

aggressive chemicals such as

concentrated chlorides, ketones

and most hydrocarbons.

The demand for natural gas is on the

rise – and with it the need for suitable

means of transportation. However,

pipelines are expensive and they often

cross through politically unstable regions,

allowing suppliers to cut off the supply

should they choose to do so. This is forcing

manufacturing and consuming countries to

increasingly rely on ships (tankers) to trans-

port the raw material. Around 270 such

tankers are currently sailing on the world’s

oceans and another 130 have already been

ordered and should be launched by 2011.

Of these, 45 are for Qatar alone, the world’s

largest producer of liquefied gas.

Tanks in tankers

Before it is shipped, the gas is liquefied by

cooling it down to minus 165°C and then

pumped into the tanks on board the ship.

This means that 600 times as much gas

can be stored in comparison with normal

temperature. While it is being pumped,

liquefied gas is subjected to a high pres-

sure of up to 150 bar. The chassis and

internal electric motors of the pumps,

which are a permanent component of the

tank’s cladding, are immersed in liquefied

gas. For this reason, they must be sealed

perfectly, particularly where the electrical

connections from the deck of the ship lead

into the pump. To do this, glass ceramic

specialist Schott uses a sealing technique

called a compression seal. “This calls for

both the glass isolator and the copper

conductor to be placed inside a stainless

steel housing and then be heated up so

that all of the elements melt together,” says

Dr. Oliver Fritz, technical manager large

scale feed-throughs at Schott Electronic

Packaging in Germany.

“As the assembly cools down, the glass

solidifies and the stainless steel housing

contracts to a greater degree than the glass.

Due to the differences in the coefficients of

thermal expansion of the materials used, the

glass isolators are subjected to compression

and a hermetic joint is created,” he adds.

Creating a hermetic seal

When the cold liquefied gas flows through

the pump, the stainless steel contained in

Oil & gas

Protecting the LNG process with glass sealsSpecial process equipment is required to transport cooled liquefied natural gas (LNG) from

pipelines to tanks. But it can easily cause havoc with electrical connections if it breaks the seal

around the pumps used to transport it. New sealing technology developed by Schott uses glass

ceramics to create a completely closed seal and ensure no gas escapes.

WORLD PUMPS August 2009Applications 13

the housing of the feed-through continues to contract, exerts even

more pressure on the glass and, thus, helps ensure that it remains

sealed. Unlike the epoxy grouting often used for these types of

seal, the pressure barrier in the glass seal does not contain any

organic ingredients that may age when exposed to severe temper-

ature cycling and, thus, lose their hermeticity. In addition, when

compared to hermetic pressure barriers that feature a ceramic-

metal bond, glass feed-throughs are less likely to experience

breakage. Schott started manufacturing the first glass-to-metal

feed-throughs for liquefied gas applications 25 years ago.

Testing for strength

Because feeding electrical conductors through to the submerged

pump represents a rather sensitive area, it is necessary to ensure

that the glass seals are carefully manufactured.

“We are capable of supplying all types of products together with

certification in accordance with the European ATEX standard and

the international IEC standard for electrical safety,” said Ulrich Dirr,

sales manager large scale feed-throughs at Schott.

“Before it is shipped, each and every liquefied gas feed-through is

subjected to one and a half times the maximum required design

pressure and then tested for density using helium mass spectrom-

eters. Testing for electric strength and insulation guarantee reli-

able performance at voltages of up to 6,600 volts and flows of 600

amperes,” he adds.

Schott Electronic Packaging (EP) also manufactures housings

and other compo nents for the reliable, long-term protection for

sensitive electronics. The core technologies are glass-to-metal

and ceramic-to-metal sealing, thermal sensing components as

well as a variety of cutting edge specialty glass competences.

Schott has received a new purchase order from Japan to supply

large scale electrical feed-throughs for pumps used in liquefied

gas applications.

ABB drives and pumps. Winning the energy challenge.

With the help of low voltage AC drives, ABB

aims to optimise the water supply, process

use and effl uent treatment to give industry

a competitive advantage. While a drive and

a pump are a formidable combination, the benefi ts of

large plant effi ciency improvements, energy savings

and less wear and tear on moving equipment, applies

equally to compressors, fans, centrifuges, mixers

and screw conveyors that are used throughout the

water process. The end result: improved asset life and

Food and drink

Ducking energy costs with VSDsA European duck meat producer wanted to save energy and reduce costs by improving the

drive control of its refrigeration plants, the greatest consumers of its electrical power. Installing

variable speed drives from ABB helped it accomplish this – and led to it installing drives on many

other types of plant in the Lincolnshire, UK-based factory.

Cherry Valley Farms is the largest

producer of duck meat and duck

products in the UK. It processes

45,000 ducks per day, weighing from 2 to

4 kg. Each duck is chilled, and the chilling

plant is a major part of the factory’s opera-

tion and accounts for a high proportion

of its operating costs. Because of this, the

manufacturer wanted to explore ways of

reducing its energy costs.

“I read in a magazine about an ABB case

study where low voltage AC drives had

been used by Northern Foods to save

energy,” said Darren Bolton, operational

improvement manager at Cherry Valley.

“We contacted the UK government-

backed Faraday Partnership to seek advice

on variable speed drives, as well as ABB

and its channel partner Inverter Drive

Systems (IDS).”

Avoiding interruption

In the food and beverage industry, the

refrigeration plant is often the single

greatest consumer of electrical power.

The plant is often sold in a price sensitive

market, so the users tend to use direct

on-line control as standard in order to

keep costs down. This means, however,

that that it is much harder to vary the

speed of motors and save money.

Moreover, most refrigeration plant users

are wary of carrying out modifications

for fear of interrupting the process – and

do not generally have the confidence to

make the conversion to variable speed

drives without specialist knowledge

and support.

ABB’s partner, IDS, looked at finding ways to

implementing energy savings. This project

initially involved setting up a seven day

energy analysis of the existing direct on-line

controlled condenser fans, in order to estab-

lish operating costs at fixed speed. The four

fans had a combined measured power

of 38 kW.A duck meat producer reduced energy costs by £25,000 a year after installing VSDs in its refrigeration plants.

www.worldpumps.com

WORLD PUMPS August 2009Applications 15

“The condenser fans are important due to

the nature of the operation,” said Blaise Ford.

managing director of IDS. ”In the first stage

of the refrigeration cycle, the refrigerant high

pressure liquid expands and absorbs heat

from the ducks being cooled, turning into

a warmer gas. This gas is then compressed.

The compressor transforms the vapour from

a low-pressure gas into a high-pressure gas.

“The refrigerant gas enters the condenser,

where fans are used to help cool it down

to atmospheric temperature and turn it

back into a liquid, ready to expand and cool

once again,” he added.

“We used the head pressure signal to

control our drive to keep this pressure

perfectly at its design point, varying the

fan’s speed to meet the chilling demand.

Previously, at Cherry Valley, this was only an

on-off cycle – the ABB drives also reduce

the inherent energy wasteful ‘cycling’ of the

original control.”

Payback from installation

Cherry Valley Farms decided to install ABB

standard drives, which were controlled

by the existing sensors for compressor

fixed head pressure. It then carried out

a further seven day energy analysis and

calculated the savings and payback periods.

It was shown that the drives had saved

13kW in total representing an annual saving

of £7,400.

As well as the energy saving on the

condenser fans, the reduced on-off cycling

of the refrigeration plant led to a further

10% reduction in compressor power reduc-

tion. It also significantly reduced fan noise,

improving the environment for neigh-

bouring properties.

Cherry Valley Farms has also installed drives

on several other types of plant in the

factory, including air compressors and water

pumps, and now makes energy savings of

£25,000 a year after installing £16,000 worth

of ABB standard drives This represents a

saving of 49.6% of the energy previously

consumed by these applications. The orig-

inal forecast estimated that payback would

be in 12.6 months but actual payback time

was only 7.7 months.

Low motor power

There are many areas where drives could be

used but IDS were excellent in genuinely

only picking up on those that could really

make a saving,” said Bolton. “Those compres-

sors that were working fine were left alone

at IDS’ recommendation. Their theoretical

results were all backed up with good graphs

and charts.”

In the past, many end users have focussed

on large power applications for their energy

saving projects. This case study demon-

strates that applications using motors

with powers as low as 5.5kW can produce

significant returns.

Construction

Going underground to ensure dry cables The population around Stockholm, Norway, is developing rapidly and new homes are needed.

A range of hard-wearing submersible pumps have helped to transport contaminated water

from a cable tunnel installed deep below Stockholm, making it possible to power a whole new

generation of buildings for the growing city.

The Baltic Sea region could be one

of the fastest developing regions

during the next few decades. By

2030, Stockholm is expected to have 25%

more inhabitants than today, and these

people require homes in one of the most

densely populated areas in northern Europe,

an area divided down the middle by Lake

Mälaren and the Baltic Sea. In Stockholm,

this growth is shown by the large quantity

of construction projects currently on the go.

Modern technology is transforming the city

making it possible to quickly receive and

integrate new inhabitants.

One of the things making it possible to erect

3,000 new dwellings within the space of a

few years is the installation of seven submers-

ible pumps deep in the bedrock below south

Stockholm. These pumps are designed to

keep a high voltage cable tunnel dry.

Tunnel construction

”We are working on five parallel fronts

at the moment, enabling us to maintain

a pace of around 80 to 100 m per week,”

says Peter Ahlgren of Oden Anläggn-

ingsentreprenad, blasting supervisor for

the new high voltage cable tunnel. The

work started in January 2007 and tunnel

blasting is scheduled for completion by

April 2010 with a further year before the

tunnel is fully operational.

The Skanstull-Solberga cable dry tunnel

is one of a number of major construction

projects in progress around Stockholm and

its importance as a part of the city’s devel-

opment is considerable. 10 km of 220 kV

residential area will now be replaced with

cables laid through the new tunnel. This in

turn will provide sufficient land near the city

for some 3,000 new homes.

The total length of the main tunnel is 6.3 km,

with an additional 800 m of approach tunnels.

The depth varies from 30 to 60 m. Two of the

five tunnel fronts are blasted from the middle

outwards and accessed via a subterranean

transport tunnel. Work on both fronts takes

place in turn, blasting on one while clearing

away the rubble on the other. On the east

front a wheeled loader is fully occupied with

lifting away about 80 m3 of rock that is taken

out of the tunnel to various stone crushers

by lorry. On the west front, the rock is granite

with seams of diabase, a very hard stone,

which means that wear on the drill bits is

harsh and the drills need large quantities of

cooling water.

Wear and tear

Reliable pumps are needed to keep opera-

tions going, having to operate continu-

ously to keep the water out, and a

breakdown would have immediate and

serious consequences.

”It is very important for the pumps to

work properly if we are to keep up to the

schedule,” says Ahlgren. ”We need to pump

out 300 l of water every minute when we’re

drilling. It’s 50 m to the surface, so the

pumps need to stand up to a good deal of

strain, but so far they have functioned well

and we are working according to plan.”

Wear and tear on the pumps is consider-

able, because the water near the drilling rig

is full of drill cuttings which act like a kind of

liquid sandpaper which rubs constantly on

the internal parts of the pumps.

The company is using two models from its

most recent pump series: the Major N-pump

which can deliver more than 35 l/s (over

2 m3/min), and the Master H pump which

has a delivery head of more than 45 m.

“These are especially strong and hard

wearing and built to withstand these kinds

of conditions,” sayd Per-Åke Jägren from

pump supplier Grindex. “They incorporate an

entirely new design, where the abrasives in

the water are kept away from the sensitive

parts of the pump. Our own tests show that

these pumps last three times longer in hard

wear and tear situations like these. What we

are witnessing here confirms our own tests.”

The water is pumped up from the lowest

parts of the tunnel pipe to ground level,

50 m up, with the pumps working in stages

using sediment tanks along the way. The

water is pumped from the drilling rig to a

pump pit, where the water is pumped to

the next intermediate station, containing

the system’s large sediment tank. At this

point, most of the remaining drill cuttings

are separated from the water and the water

pumped on upwards is in large clean. Water

samples are taken regularly to ensure that

municipal water regulations are obeyed.

Regular servicing

A Grindex Master pump installed closest

to the drilling rig is most exposed to the

drill cuttings in the water.

”This water is almost like gruel,” says Ahlgren.

”The mixture clogs up the system quickly if

the plant is not correctly built and dimen-

sioned. Grindex recommend 2000 running

hours between services, but we service the

pumps every 1500 hours to be on the safe

side. In practice this means the shortest

service interval for the pump system is two

months. However, we carry out a standard

daily inspection of the equipment.”

”We’ve been operating at full speed down

here since the end of April and every-

thing has worked properly,” he adds. ”We

have now come some way into the tunnel

construction and are working at maximum

speed. It is important to us to be able to

maintain this tempo and reliable equip-

ment is essential. Just because the pumps

are scarcely noticeable when you pass by

them in the tunnel does not make them

less important. If one of them were to stop,

everything else would stop too.”

Construction

As builders began to prepare the

ground for the construction of a

new highway tunnel in Oslo, the

excavators were not prepared for what they

were about to find buried under the mud.

As work progressed, the largest collection

of old shipwrecks ever found in Norway was

gradually uncovered.

Specialist archaeologists from the Norwegian

Maritime Museum stepped in to examine

the site and were surprised to discover

the remains of at least 14 wooden boats.

Some wrecks measured up to 17 m (56 ft)

and are believed to date from the late 16th

and early 17th centuries. The boats probably

sunk sometime after a massive fire swept

the wooden buildings of old Oslo in 1624.

After the disaster, the Danish-Norwegian

King Kristian IV had ordered Oslo city centre

moved before reconstruction started.

The wrecked boats are all fairly well-preserved

due to the mixture of mud and fresh water

at the site, which is located where the rivers

run into the sea at Bjoervika, which part of

Oslo’s old port. It became a remote area

after the city was moved.

A quick process

According to Lin Hobberstad, an onsite

archaeologist who oversaw the safe

recovery of the shipwrecks, the removal

process to recover the boats had to take

place as quickly as possible so that the

ships could be examined and ensure that

construction work on the tunnel could start

again quickly.

“Oslo Vei, a construction specialist based

in Oslo, recommended Tsurumi pumps for

the onsite drainage,” she said. “Good reliable

pumps are an essential part of an archaeo-

logical project like this and Tsurumi was an

obvious choice.”

The company installed 70 Tsurumi LB-480A

contractor pumps which are single-phase

portable pumps with level sensors which

start and stop the pump automatically. The

LB-480A’s electrode level sensor responds to

the level of water, switching on the pump

as it rises. As the water level drops away,

the automatic timer switch stops the pump

after just one minute. This helps alleviate the

Steering an even keel with effective drainageWhen archaeologists discovered a haul of 16th century shipwrecks at a Norwegian

building site, they realised that quick and efficient drainage had to be attempted to

ensure both safe examination of the ships and timely completion of the building.

A range of Tsurumi drainage pumps provided the answer.

problems associated with allowing a pump to

operate non-stop, including greater wear and

tear and more frequent maintenance. Energy

consumption can also be higher leading to

greater energy bills for the contractors – and

more CO2 into the atmosphere.

The pumps also feature dry running which

helps avoid damaging the pump, and

reduces the need for higher staffing costs.

The 0.48 kW power-rated LB-480A is also

robust and durable during long periods of

continuous use, pumping up to 225 l/m

at maximum capacity. A combination of

a rubber pump chamber and a urethane

vortex impeller provides wear resistance,

vital for the water in this kind of application

which contains sand and silt in suspension.

Beefing up cattle feeding efficiencyA US beef producer uses corn-distilled soluables (CDS) as a feed ingredient to condition its cattle.

To make loading, transporting and storing the viscous CDS as easy as possible using tanker

trucks, the company opted for four Gorman-Rupp Super T-Series pumps. They proved both

reliable and easy to maintain.

Located in Central California, Harris

Farms Inc. has been a successful

family-run operation since its begin-

nings in 1937. Since its founding in Fresno

County, Harris Farms has grown into one

of the largest family-owned, vertically inte-

grated agribusinesses in the US. The Harris

Ranch has perhaps become best known

for producing the quality beef. It has a

fully integrated production system controls

every aspect of beef production, from cattle

procurement to feeding, processing to

distribution. All cattle are fed and processed

at separate facilities.

Harris Feeding Company currently

employs approximately 200 people and

has a capacity to feed 120,000 head of

cattle. However, the company is more

than a typical ranch or farm, and does

more than just supply grocery stores and

restaurants with beef. Under the direction

of feedmill superintendent Ken Zeman,

the company operations include a cattle

feed manufacturing facility that stores

and transports corn-distilled soluables

(CDS), which is a byproduct of ethanol.

CDS is used as a feed ingredient, and

protein source, as well to condition the

feed before feeding the cattle. To pick up

the CDS, the company sent its trucks to

ethanol production facilities, where it was

purchased and then loaded into a tanker

truck trailer.

To mount the arduous task of quickly

and efficiently moving the CDS, in order

to maintain a quick operational efficiency

while minimizing man-hours, Zeman

brought Bogie’s Pump Systems onboard.

Zeman had first worked with the company

when he rebuilt a pump that was used for

unloading Pre-mix. At that time, Zeman

mentioned the CDS transportation and

storage problem he was facing, and felt

confident in the capabilities and knowl-

edge of the team at Bogie’s to help him

move forward with the project.

To make loading, transporting and storing

of the CDS as seamless as possible,

Cameron Storrar of Bogie’s Pump Systems

had to find a way to quickly load and

unload the fleet of eight tanker trucks

travelling between the Harris Feeding

Company and the ethanol plants. “There are Four Gorman-Rupp Super T-series pumps provide reliability for Harris Ranch, a US beef producer.

www.worldpumps.com

WORLD PUMPS August 2009Applications 21

four unloading pumps and we can unload

four trucks at a time,” said Zeman. “When

I told Storrar about our need to transport

approximately 17 loads of product a day,

and then transport it to the mill where it is

then pumped through unloading pumps,

he saw our problem and began to design

a solution that would meet the needs of

our company.”

Storrar began to implement a solution that

not only provided for the transportation

and storage of CDS, but could also do it

efficiently and safely. In this particular case,

the challenge was to unload as many trucks

as quickly as possible, deliver the CDS to

the storage unit and then to turn around

and make another run. A properly working

pumping system was key to ensure that this

side of the operations ran smoothly.

Easy maintenance

“For the unloading pumps, Harris Feeding

Company opted for four Gorman-Rupp

Super T-Series pumps,” said Storrar. “The

reason why I chose the solids handling

pump for this application was because

the customer specified they didn’t want a

special pump that would take a long time

to get parts for or that was hard to repair,”

continued Storrar. With the Super-T tech-

nology, design features such as an external

shimless adjustment, dual protection of

bearings and an ‘easy-grip’ cover plate

handle make maintenance easier for the

growing cattle operation.

Because CDS is a thick, pasty substance with

a degree of acidity to it, Storrar needed a

pump that could handle the viscous liquid

it was transporting. As CDS is different from

most fluids pumped, it requires that certain

parameters be met in order to move the

somewhat dense substance.

Even though Harris Feeding Company had

some previous experience with Gorman-

Rupp pumps, none were as large as the

ones that pump straight into the mixer

box. “I’ve used some of the smaller pumps,

which were Super T-3’s and they just

perform. I haven’t encountered any prob-

lems, and Storrar will probably be retired

before I have to replace that one – and

I think that will be many years down the

road,” said Zeman.

With easy installation, the Super Ts are

able to unload a truckload of 52,000

pounds in 12 minutes. “I chose the most

common pump from Gorman-Rupp

in order to ensure that we constantly

have that model in so that if there were

any maintenance issues, they could be

addressed swiftly with very little down-

time,” said Storrar.

The fifth pump that was installed by

Bogie’s serves a different purpose – it’s an

unloading pump that is fully automated

and it transfers the product from the

storage tanks to the working tanks and

from there it is pumped back into the feed.

There, the CDS is mixed into the feed mill,

which is the onsite feed manufacturing

facility that is located at the Feedlot.

The solution that was put into place

makes the loading and unloading

process efficient and easy to maintain.

“When the pumps came in, they were

ready to go. All we had to do was hook

up power and we were off,” said Zeman.

“The project cost was about US$500,000

and the project return on investment was

very attractive.

To meet growing environmental and

government requirements, the farm of the

future will undoubtedly be a cutting-edge

enterprise.

Since CDS is a thick, pasty substance with a degree of acidity to it, Super T-Series stainless steel pumps were selected.

Large Gorman-Rupp pumps were selected to pump directly into the mixer box.

Operating

Pumps as turbines for water industryRunning pumps as turbines is a well-known concept in the water supply industry. It is seen as an efficient method of generating power as well as recovering energy and contributing to savings. There is the added benefit that pumps are less complicated to operate than turbines. Bryan Orchard reports.

The concept of running a centrifugal

pump in reverse rotation mode has

been recognised by pump manufac-

turers for many years and within the water

supply industry this concept has been

exploited to a limited degree as a means

of generating power in locations where it

is considered too expensive to purchase a

hydro turbine. It has not gone unnoticed

by water suppliers, operators of small

hydropower plants and pump manufac-

turers that running pumps as turbines

(PaTs) is an efficient method of generating

energy as well as recovering energy and

contributing to energy savings. In the

current world economic climate where

reducing energy costs is becoming a high

priority it is not surprising that PaTs are

starting to create significant interest.

KSB Aktiengesellschaft is one of a group

of pump manufacturers that is active

in investing resources in PaTs and the

company has recorded considerable

success with its solutions in several

parts of the world. Applications where

KSB already has pump units on PaTs

duties include small hydropower systems

(<10 MW), major water transport systems,

reverse osmosis and industrial systems

where the technology can be employed

as an alternative to throttling devices.

“KSB has been active in supplying volute

casing and ring-section pumps for PaTs

duties over several years, mostly into the

small end of the hydropower market,”

says Sander Klos, KSB’s senior project

manager, Small Hydropower. “In the small

end market power requirements are

typically up to100 kW, but the investment

costs are relatively high for conventional

hydropower units and the payback

period can be as high as 15 years. With

our PaTs solution, the payback period

can be as short as three years and there

is the added benefit that pumps are less

complicated to operate than turbines.”

He continues: “For locations where there

is a relatively constant water supply but

power supplies are unreliable or even non-

existent, PaTs are a simple and economic

approach to generating power. Not only

that, PaTs can also have a role to play in

locations where the power supply is readily

available and reliable. KSB is now supplying

systems for very large water supply infra-

structures which traditionally have been

the domain of conventional hydroturbines.

Here the power being generated is contrib-

uting to the overall running costs of the

water pumping stations and putting power

back into the national grid.”

Identifying the potential for running

pumps as turbines originated when

users in the water industry wanted to

know what the impact would be on

their systems should a pump stop and

Figure 1. KSB Etanorm pumps operating as turbines in a water pumping station.

WORLD PUMPS August 2009Feature 23

www.worldpumps.com

then go into reverse operation. This was a

scenario which was raised with KSB and in

response its hydraulics engineering depart-

ment was brought in to examine this issue

and to calculate the turbine performance

curves of pumps when running in reverse.

They discovered that the behaviour of the

pump running as a turbine is very good as

the energy output could be higher than the

energy input used to run it as a pump.

Hydraulically, the pump in turbine mode can

handle a higher volume of water than when

in conventional pumping mode. There is a

higher flow inside the pump and this means

that the amount of energy that comes out

is higher. An added bonus is that when it

is in reverse operation and running as a

turbine the pump runs more efficiently than

in conventional mode. The operating range

for ring section and volute casing pumps is

illustrated in Figure 1.

Cost-effective power

With the pump running in reverse, the shaft

torque can be utilised in a number of ways.

When attached to a generator it is the mains

frequency that determines the speed. In such

a scenario to generate a frequency of 50 Hz

the pump as turbine would have to run at a

rate of ~1515 rpm (a little over-speed). Incor-

porating frequency inverters and appropriate

mains feed circuitry would create greater

speed variation without adding very much

cost to the package. It can be seen, therefore,

that this is a very cost-effective way of gener-

ating power even when compared to the

higher efficiencies of a conventional turbine.

An alternative application would be to

connect a PaT directly to a driven machine,

another pump being an example, which

does not have either a motor or generator

to fix the speed. This mechanical solution

to providing energy has been successfully

supplied by KSB to locations in many parts

of the world where a power supply is not

available for operating water distribution/

transfer pumps but there is sufficient energy

in head of water to drive the PaT.

In order for this type of unit to operate

effectively both the PaT and pump must

have ‘equal output’ at both ends of their

shafts, which means that they must be rigidly

connected to each other by couplings or a

gearbox. If the Pat does not have sufficient

strength, then the pump to which it is

connected will not be able to provide the

necessary discharge head. On the other hand,

if it is too strong, the Pat will either waste

energy or overload the pump.

Because of its exposure in all sectors of

the global water supply industry, KSB has

products that have been proven over many

years. Pumps that the water industry will

be more than familiar with are the Omega,

Etanorm, Multitec and RDL ranges and it

is these products that KSB is advocating

for hydropower duties for heads above

10 m. Where the head is below 10 m and

flow rates are high, then axial flow pumps

provide the most effective solution. The

scope and operating capabilities of these

pumps has enabled KSB to establish a

business sector dedicated to designing PaT

modules which can be used in single and

multiple configurations (see Figure 2).

The capability to operate multiple PaT

modules is highly relevant for locations

where the water supply can fluctuate.

Unlike conventional turbines, PaTs do not

have adjustable guide vanes for adapting

to fluctuations in the water supply and this

is perceived as a drawback to their use. By

employing a number of differently sized

units to distribute the total volume of water

available, this difficulty can be overcome.

According to KSB, running several units

requires only the minimum of control and

although this type of arrangement does

diminish the cost advantage of the PaT over

the use of a single turbine, it remains advan-

tageous in terms of appropriate technology.

Quite simply, pumps are easier to operate

and maintain that conventional turbines. ■

When the liquid in a centrifugal pump flows from the discharge outlet to the suction inlet it follows that the impeller will turn in the opposite direction. Should the head of pressure be high enough to overcome the breakaway torque of both the impeller and shaft, the torque can be employed to drive a generator.

Design and performance

The results of a study on the hydraulic performance of open-bottom canned pump intakes should aid engineers and pump users to design these systems with reduced velocity fluctuations and undesirable flow rotation. David Sanders of Sunrise Engineering with Steven L. Barfuss and Michael C. Johnson of Utah State University provide the details.

Pump systems often require the

use of an open-bottom canned

intake to house the vertical

turbine pump. A canned pump can be

defined as one in which the pumping

unit is housed within a shaft and may

be considered in two separate

categories – open-bottom and

closed-bottom. Open-bottom canned

pumps draw water from a horizontal

header, which passes flow along the

bottom of the open can with enough

head to at least submerge the pump

bell within the can. Closed-bottom

canned pumps are enclosed at the

bottom, and water fills up the can by

way of an inlet pipe on the side of the

can. This article investigates open-

bottom canned pump intakes and the

measures necessary to improve

hydraulic performance and reduce

velocity fluctuations and flow rotation

under varied conditions.

In open-bottom canned pump systems

where the average velocity in the

header (perpendicular to the can)

becomes greater than the average

velocity in the riser, a number of

potential problems may arise. Of these,

the potential for vortices, flow pre-

rotation (annular flow pattern with

tangential velocity occurring upstream

of the turbine) to the pump impellers,

turbulence, and unsteady and non-

uniform flow at the pump throat can

be of particular concern. The problems

may be compounded as header veloci-

ties increase and as the distance from

the pump bell to the header (YBell)

decreases. The previously identified

problems can reduce pump efficiency,

increase maintenance and, over time,

cause damage to the pump. Because

of this, the American National Stand-

ards Institute (ANSI) and the Hydraulic

Institute (HI) have established accept-

ance criteria for physical model tests of

open-bottom canned pump systems.

These criteria include having a circula-

tion angle, θ, less than 5°; time-averaged

velocities at points in the throat of

the bell should be within 10% of the

cross-sectional area average velocity;

and time-varying fluctuations at a point

should produce a standard devia-

tion from the time-averaged signal of

less than 10%. The circulation angle is

defined as:

θ = arctan(Vt /VA)

where Vt is the average tangential

velocity of the tip of the rotometer

impeller, and VA is the average vertical

velocity at the pump throat.

HI guidelines

In order to achieve acceptable hydraulic

performance in open-bottom canned

pump intakes, the HI has published

the following design and operation Figure 1. Simple schematic of the IPS3 forebay model.

Improving open canned systems

WORLD PUMPS August 2009Feature 25

guidelines for the benefit of the engineer and

pump user.

1. A vortex suppressor is necessary to break

up abnormal flow patterns ahead of the

pump suction bell.

2. The maximum horizontal header velocity

is 1.8 m/s (6.0 ft/s).

3. The maximum riser velocity is 1.5 m/s

(5.0 ft/s).

4. The minimum distance from the

horizontal header to the bottom of the

pump bell is 3.0xD, where D is the inside

diameter of the riser.

5. The pump must hang centred in the

vertical riser pipe.

6. The minimum distance from the

submerged pump bell to the water

surface is 1.0xD.

7. Open-bottom canned intakes with

flow rates exceeding 315 litres/s

(5000 US gallons/min) per pump require

a model test.

In researching this topic, any background

or supporting information available was

exhausted, but very little useful informa-

tion was found. Therefore, data from

physical models took on great significance

in this study.

Physical modelling

As a basis for research, the data from three

physical model studies were used. The first

was that of an underground chamber with

a horseshoe-shaped cross-section, known

as Intake Pumping Station No. 3 (IPS3),

from which water would be pumped to

a water treatment plant and then to a

nearby city. In the IPS3 physical model

study, a pump forebay (header) using

11 pairs of identical pump shafts (risers)

connected to the top of the forebay was

modelled. Figure 1 shows a schematic of

this model.

The second model study used was that of

Intake Pumping Station No. 1 (IPS1). The

setup of IPS1 was similar in design to that

of IPS3, but it had only 10 pairs of pump

shafts (risers), and the forebay (header) had

a much smaller cross-sectional area and,

consequently, a much higher header velocity

than IPS3. A schematic of the IPS1 forebay

model is shown in Figure 2.

The third model study included a single

acrylic pipe (riser) that branched perpendic-

ularly off a 61.0-cm (24-inch) line (header).

This model was used to determine the

similarities between the IPS3 and IPS1 data.

Figure 3 shows a schematic of this research

model.

The objective of this study was to

determine system configurations that fall

outside the HI guidelines. This makes it

possible to install pumps closer to the

header or operate the system at higher

header or riser velocities than the HI

guidelines suggest.

The models

The pump shafts for the models were

constructed of clear acrylic tubing, which

enabled the observation of the flow

conditions to the pump bells, including

vortex formation and persistence as well

as other flow rotation. The pump throats

and pump bells were also constructed of

acrylic, using moulds to form the bells.

The pump bells in each of the three

model studies were tested with and

without vortex suppressors. Figure 4 shows

an example of the vortex suppressors used

in these model studies.

Acrylic turn columns were fabricated and

connected to the pump bells, allowing the

bells to be rotated within the risers a full

360°. These turn columns allowed for the

collection of velocity data at any position

along the circumference of the pump throat

using a single permanently mounted Pitot

tube and static pressure tap. These instru-

ments were used to evaluate the potential

for velocity fluctuation and flow rotation

problems at each pump throat. Differential

pressure transducers, which are accurate to

1.0%, were connected to each Pitot tube to

measure the velocity head. A rotometer, as

described in the HI Standard, was mounted

in each pump throat. These rotometers were

used to detect rotational flow entering the

pump throat, enabling the calculation of the

circulation angle.

Flow rates through the models were meas-

ured using calibrated orifice flow meters

capable of reading to within 0.5%. For

low flow rates, a weigh tank was used to

increase the accuracy in the flow meas-

urement and flows were regulated using

control valves.

Conditions investigated

With three variables in this study (Vr , Vhand YBell), the ratio of Vr /Vh was used to

create a dimensionless control parameter

that would facilitate the comparison of

different test scenarios. In this ratio, Vr is

the flow velocity through the riser, calcu-

lated immediately upstream of the bell

in the shaft, and Vh is the flow velocity

through the header, calculated immedi-

ately upstream of the riser. This velocity

ratio was used in comparing the hydraulic

conditions at varying YBell distances. The

tests run on each model had a Vr /Vh ratio

range of nearly one order of magnitude.

The research model was tested with Vr /Vhratios ranging from 0.15 to 1.23. In the

IPS1 model study, the ratios ranged from

0.58 to 5.8, while in the IPS3 model study,

the Vr /Vh ratios ranged from 3.5 to 34.8.

While it would be desirable to operate

each model over a wide flow range,

physical limitations restricted the range of

possible velocity ratios. Therefore, while

Vr /Vh ratios in the IPS3 model reached

34.8, Figures 5-7 only show ratios up

to 8.0 because the IPS1 model and the

research model were physically limited

to ratios lower than 8.0. All IPS3 tests

with ratios higher than 8.0 yielded results

within the HI Standard.

Test results

Figure 5 (a and b) shows the velocity

fluctuation and Figure 6 the velocity

distribution, while Figure 7 compares the

circulation angle calculated for each test

condition. All these figures also illustrate

the published HI standard in reference to

the actual test data for comparison. The

figure icons differentiate between specific

model tests and describe the distance from

the pump bell (in riser diameters) to the

header (#xD).

As illustrated in Figures 5 and 6, the velocity

ratio had a direct effect on the velocity

fluctuations and the mean velocity distribu-

tions, with or without the vortex suppressor.

The apparent uniform trend of the data for

the velocity distributions and the velocity

fluctuations both with and without the

vortex suppressor is noteworthy. It appears

that at higher velocity ratios, the distance

from the pump bell to the header (YBell) has

a less significant impact on the system. The

circulation angle (Figure 7) was reduced by

the addition of the vortex suppressor.

Discussion

Velocity ratio

While the HI’s guidelines are an excellent

resource for helping the engineer and pump

user design and operate a system that falls

within their acceptance criteria for model tests,

the velocity ratio used in this research study

would be an additional helpful tool that would

allow engineers and pump users to change

the configuration of the system to meet their

needs. This could include having YBell distances

less than the distance suggested by the HI, if

need be, to access more water. It could also

permit the use of higher average velocities in

the riser if more water were needed, as long

as the correct header velocity was used to

achieve an acceptable velocity ratio.

With the use of Vr/Vh ratios, the HI design

parameters are extended beyond what is pres-

ently available. The determination can be made

that without a vortex suppressor, at a YBell dis-

tance of 1.0xD, Vr/Vh ratios above the ‘minimum

acceptance ratio’ of 1.0 should result in condi-

tions that would fall within the HI Standard.

Therefore, systems that need to operate at a

header velocity of 1.8 m/s (6 ft/s) – the HI limit

– would need to keep the riser velocity above

1.8 m/s (6 ft/s). Conversely, if systems need to

operate at a riser velocity of 1.5 m/s (5 ft/s)

– the HI limit – the header velocity would

need to stay below 1.5 m/s (5 ft/s).

Vortex suppressor use

The use of a vortex suppressor in these

pumping conditions lowers the ‘minimum

acceptance ratio’ to 0.63. Therefore, if systems

need to operate at the 1.8 m/s header

velocity limit with a vortex suppressor the

riser velocity would need to exceed 1.2 m/s.

For a riser velocity of 1.5 m/s, the header

velocity would need to stay below 2.4 m/s. It

should be remembered that one purpose of

the vortex suppressor is to reduce vortices,

and it may therefore need to be used in

conditions where vortices are more likely.

Again, these ratios must be used with consid-

eration of the system’s capacity limits in mind.

These calculations offer much more freedom

to the design engineer and pump user in the

event that higher velocities than those given

in the HI design parameters are required

within the pump system.

The circulation angle was lowered by the

vortex suppressor. If surface or sub-surface

vortices were present in the tests, the vortex

suppressor would have played an even more

significant role.

It should be remembered that one of the stip-

ulations in the HI Standard is that the design

and operation guidelines given are especially

applicable to pumps that will be pumping

315.5 litres/s (5000 USgpm) or less. The

standard suggests that open-bottom canned

intakes with flows greater than 315.5 litres/s

per pump require a model test.

Conclusions

Open-bottom canned pumping systems are

subject to a number of potential problems,

as outlined in the introduction, which has

prompted the HI to develop acceptance

criteria for pump intakes. To help meet these

criteria, the Institute has also established

design guidelines for open-bottom canned

pumps. These guidelines include the use

of a vortex suppressor, maximum hori-

zontal header velocity of 1.8 m/s, maximum

riser velocity of 1.5 m/s, and minimum

YBell of 3.0xD, as detailed earlier.

The results from the three separate model

studies discussed here indicate that the

Vr /Vh velocity ratio plays a very important role

in determining the ability of a pump system

to operate within the HI acceptance criteria.

These results will be helpful in predicting

pump system performance, based on this ratio

and YBell. With these results, the engineer and

pump user will be able to position the pump

bell in an open-bottom canned pump system

below the suggested 3.0xD using an acceptable

velocity ratio. With YBell distances greater than

or equal to 1.0xD, a velocity ratio of 1.0 is the

minimum acceptable ratio for a pump system.

Lowering the pump bell past 1.0xD would

require raising the minimum acceptable velocity

ratio to 1.4. Furthermore, engineers and pump

users will also be able to use Vr/Vh ratios to

achieve the needed velocity through the header

or riser without turbulence or rotation problems

in the pump. A vortex suppressor is recom-

mended for use in these pump systems.

It is apparent from the data that as the Vr/Vhratio

increases, the velocity fluctuations and turbu-

lence within the pump bell decrease. This implies

that the magnitude of this ratio is the factor that

plays the most significant role in velocity fluc-

tuation and flow rotation within open-bottom

canned vertical pump intake systems, although

the ratio is limited by the capacity of the system

itself. The YBell distance plays a significant but

secondary role in this, giving less stable results

as the distance decreases between the pump

bell and the header. ■

Energy saving

Blade adjustment cuts energy costsCooling water pumps for power plants can save energy by adjusting the flow rate. Gerd Witte and Dr Manfred Stollenwerk explain that pumps with an adjustable pitch angle of propeller blades can lead to cost savings. Depending on the load profile and internal energy costs, the ROI can be reached within two to three years.

The production of electrical energy is

secured by the mix of different power

plants. On the one hand side, power

plants for the base load are running

continuously with a capacity of 100% load.

Other power plants are covering times with

fluctuating energy demand and therefore

running with different load cycles. In time

of lower load, these power plants need less

cooling water respectively. The usage of

cooling water pumps with adjustable

flow rate can save energy compared to

pumps without the possibility to adjust

the flow rate.

For the estimation of the energy and

cost saving potential we have made

a comparison between pumps with a

constant flow rate and pumps with an

adjustable flow at different load profiles.

Flow rate control

There are three different technical

realisations known for an active flow rate

control of cooling water pumps:

Motor speed control by means of a

frequency converter: Relative expensive

and less suitable due to the relatively

high static part of the system

resistance curve.

Pre-vortex controllers: More suitable to

adjust the pump to changing head. The

ground floor of the inlet chamber in front

of the pumps must be excavated deeper

due to the length of the pre-vortex

controller and its pressure losses, which

are resulting in higher NPSHR.

Variable pitch angle adjustment of the

propellers: Most suitable for an active

adjustment of the flow rate due to the

special head/flow characteristic for

different angles of the propeller blades.

Therefore, this article focuses on the

technical solution using propeller pumps

with variable pitch angle of the propeller

blades. The statements included in this

article therefore are valid only for pumps

of this type and comparable applications.

For other circumstances other control

systems may be preferable.

Variable pitch angle adjustment

The variable pitch angle adjusting device

is mainly consisting of three gears and

a hollow drive shaft witch contains the

adjusting shaft (Figure 1).

The adjusting of the pitch angle can

be performed during operation or also

during shut-down of the pump. A geared

electrical motor is energized, when

adjustment is performed. Via the differ-

adjustment is performed. Via the differential

gear a relative rotation is transmitted to

the adjusting shaft, so that the speed of it

is higher or lower – for both directions of

adjustment – than the speed of the hollow

drive shaft.

This relative rotation effects an axial

movement of the adjusting element

within the propeller hub by means of a

threaded bush. The adjusting element is

provided with inclined grooves, in which

the adjusting levers of the propeller blades

are mounted. When the adjusting element

is moving axially, the propeller blades are

rotating simultaneously by approximately

20° from min. to max. angle. All posi-

tions within these limits are adjustable,

depending on the duration the geared

adjusting motor is energized. The extreme

positions are protected by limit switches as

well as the max. torque.

Comparisons

The comparison of the energy consumption

is made for following pump types:

Pump with mixed flow impeller with fixed

blades, n = 426 rpm

Pump with mixed flow propeller with

adjustable pitch gear angle; n = 370 rpm

Both pump types have a motor power of

P= 3.000 kW incl. 15% margin. The diameter

of the discharge elbow is 1.800 mm (72”).

The calculations are based on the cooling

water demand of a conventional, coal-fired

800 MW power plant with a cooling tower

and two 50% cooling water pumps.

The 100% operating point of the cooling

water circuit is defined by a total flow-

rate of Q= 66.574 m³/h (293.145 gpm US),

respectively of 33.287 m³/h per pump

(146.573 gpm US). The total head at full load

is H= 25,4 m (83,3 ft).

Results

For both types of pumps we have calcu-

lated the characteristic curves of the total

head H(Q), shaft power P(Q), efficiency

η(Q) and NPSHR (Q). The results are shown

in Figure 2 (fixed impellers) and Figure 3

(adjustable impellers).

The pump and system characteristic curves

are shown for single and parallel operation.

The latter is the nominal operating point of

the plant at 100% load.

On top of the diagrams the characteristic

curves head [m] versus flow rate [m³/h]

are shown.

For the fixed impeller pump there is only

one intersection of the Q-H-curve with the

system resistance curve – which represents

the operating point – for single pump

or two-pump operation, respectively. The

curves for two-pump operation are resulting

from the addition of the flow rate of two

pumps at the same head. This is valid also

for the variable pitch angel propeller pumps.

For the adjustable pitch angle propeller

pump there are several Q-H-curves plotted,

each of them for a certain pitch angel,

which is noted at the graph. Because it

is possible to adjust any number of pitch

angels within the possible range from

min to max, there is a large operating

range of cooling water flow rate available

from approximately 30% to 60% (single

pump operation) and 60% to 105% (two-

pump-operation).

Please note, that the indicated operating

range is not only limited by the min. and

max. possible pitch angle, but also by the

available and required NPSH of the pumps.

These graphs for 0%-head drop are plotted

at the bottom of the diagrams.

The efficiencies versus flow rate complete

the diagrams. The pump efficiency consi-

dering the internal head losses is plotted.

Motor efficiency is not considered, this

would increase the power savings by

approx. 5%. The difference between the

system resistance curves is due to the

minimum or maximum water level in the

cooling tower basin.

Below the Q-H-curves the pump shaft

power is plotted, for single and two-pump

operation. An additional requirement of

the project is that at shut-down of one

pump the remaining operating pump shall

discharge a minimum flow rate of 60% of

full load ( = 39.944 m³/h).

Both pump types selected can be operated

at this run-out point, however, with some

advantages for the propeller pump with

regards to NPSHR and efficiency.

Energy saving

For the calculation of energy consump-

tion and saving, we have analysed three

different load profiles with an average load

from 90% (profile 1), 87% (profile 2) and

85% (profile 3). The details of the power

load profiles are shown in Figure 4. The

detailed energy consumption is calculated

for pumps with fixed impeller blades

without flow control and for the pumps

with variable impeller blades, where the

impellers are adjusted to the optimum

operation point of the needed cooling

water amount. It can clearly been seen that

there are reasonable energy saving poten-

tials, especially for lower power loads. For

the estimation of the cost saving we have

assumed production cost for the energy of

0,03 € per kWh.

Summary

In summary, using pumps with

adjustable pitch angle of the propeller

blades can lead, depending on the load

profile, to cost savings of up to €254 000

per year. Taking the additional costs for

the pitch angle control of approx. €200

000 per pump (400 k€ for two pumps)

into consideration, a return of investment

can be achieved within approx. two years.

Please note, that the adjusting gears

are active only during the changing of

the blade pitch angle, the predominant

operating time the gears are free of load.

One of the challenges facing plant

instrumentation engineers today

is the effective and reliable

monitoring of thrust bearing wear in

critical pump applications. Typically

pumps of this type are in continuous use,

and operational downtime is normally

only permitted during planned outages.

Predicting the wear, and hence the

requirement to replace the thrust pads, is

essential to fit in with this regime.

With rotational speeds between 3000 and

7000 rpm, protection against potential

pump damage is also key, as excessive

thrust wear can not only damage the

bearing assembly but also the impeller,

resulting in the plant potentially being

out of action for six months or more.

Condition monitoring specialist Sensonics

has been working with plant instrumenta-

tion engineers for many years, providing

effective measurement regimes through

its range of equipment and services.

Monitoring solutions

What types of thrust monitoring techniques

are available for boiler feed pumps (BFPs)?

How is implementation to be achieved?

A high-pressure BFP set will operate with

pressurized fluid within the thrust bearing.

Permissible total wear on the thrust pad

from new is typically between 0.75 mm

and 1.25mm, before inspection or replace-

ment is required. Older BFP designs use a

hydrodynamic (water) lubrication system

driven from the impeller action. Tilting

pad thrust bearings, common for the

newer BFP designs, use a high-pressurized

hydraulic oil supply to minimize friction.

This is particularly effective at start up, or

slow rotating speeds, where the hydrody-

namic effect – which establishes itself at

rated speed - is not present.

Thrust pad wear indication can provide

valuable feedback on how well the lubrica-

tion technique is working. Measurement

of excessive wear could be because of

inadequate oil pressure or flow around

the assembly; a worn balance device can

produce uneven forces on the bearing with

the same result. Wear rates in combination

with vibration measurements can provide

a good guide to the best efficiency point

(BEP) performance of the pump.

In addition, thrust monitoring is a key

protection measure to ensure automatic

shutdown in the event of safe operating

Condition monitoring

Keeping track of bearing wear Effective monitoring of thrust bearing wear is a crucial factor in preventing pump and impeller damage. Sensonics’ Russell King describes the techniques available for monitoring thrust bearings on boiler feed equipment, and explains how the technology can be successfully implemented and commissioned.

limits being exceeded. A recent example is

that of a 350 MW turbine set and pump,

where a Sensonics thrust monitoring system

enabled safe shutdown of the BFP. This

prevented bearing damage and a long

outage period for the turbine set. While it is

fairly straightforward to monitor the end of

the drive shaft for changes in pad thickness,

the measurement is complicated by the

following factors:

Shaft and casing expansion

Float in overall assembly

Measurement target shape and size.

Probe positioning

The challenge is therefore a measurement

range for the shaft position that covers

the mechanical expansion float, yet still

provides accurate thrust wear indication.

Modern eddy current proximity probes,

such as those by Sensonics, are proven in

such applications. For example, an 8 mm tip

device having a half sensitivity arrangement

offers a 4 mm (4 mV/um) range. If a greater

range is required, an 8 mm range probe

(20mm diameter) is recommended.

Special bracketry is usually required to achieve

correct probe positioning and adjustment.

Dual redundant systems are common, because

they help ensure continued measurement

integrity in the event of a probe failure.

Mounted axially to the shaft, the ideal location

is facing the shaft end – drilling and tapping

the cover plate is common. If this is not

possible, or if the target area is insufficient

(must be two x probe diameter), a shaft collar

can be used, or added, between the thrust

and shaft end bearing. This has the advantage

of being located closer to the thrust bearing

and, therefore, it reduces the measurement

error resulting from expansion and other shaft

effects. Both probe types can be obtained in

a straight or disk format to suit either a direct

or collar mounting arrangement.

Proximity probes, such as those by Sensonics,

should comply with the API 670 standard

and can be obtained in a set range of tuned

cable lengths. The probe is used in conjunc-

tion with a driver / lineariser to provide a

voltage output proportional to gap.

To complement the probe system, a thrust

monitor and protection unit is required to

process the measured signal.

Commissioning

To commission such systems, the probe is

adjusted against the shaft target at known

increments and the linearity of the measure-

ment system is checked – some adjust-

ment at the driver is possible if the target

is not ideal. With the set cold and the shaft

positioned with the thrust pads against

the bearing disk, the probe is set against

the target at a gap (typically mid-range),

which permits the full measurement range

required, including the float. Note that not

taking all the shaft conditions in to account

could result in the probe being damaged.

The monitor unit is adjusted to read zero. If

the shaft cannot be set on the thrust pads,

it is still possible to set up the zero point

provided the shaft position is known relative

to the normal thrust pad position. Once

rated speed and load are achieved, minor

zero adjustment may be required to allow

for mechanical expansion. Positive and nega-

tive alarm levels can then be set, and from

the point of commissioning, the thrust pad

wear can be monitored with time.

In addition to thrust, it is also usual to

monitor vibration, temperature and speed

on such plant. A wide range of multi-

channel monitoring and protection equip-

ment is available for these functions. ■

Net positive suction head (NPSH)

quantifies the level of usable

energy at the pump inlet. It is

usually expressed in metres of liquid

column (mlc). The objective of NPSH

calculations is to verify that the pump

will be operating outside the cavitation

risk zone for a given process.

Centrifugal pumps

The NPSH concept is well understood

in the centrifugal pump sector and the

approach is fully standardized.

NPSHa

This is the available NPSH.

In the suction tank, we have a certain

pressure – minus the liquid vapour

pressure at the working temperature to

prevent cavitation, this pressure repre-

sents the usable energy at the level of

the storage tank.

The geometry of the installation defines

the differential elevation between the

liquid level in the suction tank and the

pump itself. When positive, the pump is

in the flooded suction configuration and

can benefit from extra usable energy.

When negative, the pump is in the

suction lift configuration and benefits

from less usable energy.

Along the suction pipe, we have friction

losses that can be easily determined from

tables or by calculation, based on suction

equivalent length. Component manufac-

turers give the equivalent length of each

of their products (elbow, valve, reduction

nozzle, etc.) to facilitate this approach.

Friction losses reduce the usable energy.

Combining these system parameters

determines the available NPSH (NPSHa)

at the pump inlet, the determination of

which is the sole responsibility of the

purchaser.

NPSHr

For their part, the pump manufacturer

will qualify their pump, particularly by

Operating

Applying NPSH to metering pumpsNet positive suction head calculations are routinely used to establish whether centrifugal pumps will operate satisfactorily in a given process. However, extending the NPSH concept to metering pumps presents a number of difficulties, as Patrick Deniau of Milton Roy Europe explains.

Figure 1. The PRIMEROY®L, the most recent metering pump launched by Milton Roy, offers a minimum positive inlet pressure (MPIP) of more than 8 m suction lift.

This trilogy of pumping system guides introduces a step

change in the knowledge of pump users by focusing on the

opportunities that are available to reduce energy consumption

in pumping systems. The reality is that to optimise pumping

systems many current practices will need to be changed.

measuring the pump’s required NPSH

(NPSHr).

At a given working point, the pump will

be installed with a starving device on its

suction line so that the test loop can deliver

an adjustable NPSHa. At the point where the

NPSHa is low enough to affect the pump’s

volumetric efficiency (usually by 3%), the

value is normalized as the pump’s NPSHr.

This data is the sole responsibility of the

pump manufacturer.

NPSH criterion

It is the responsibility of the pump supplier

to select a pump with an NPSHr below the

NPSHa given on the customer datasheet,

with a sufficient safety margin (usually

0.5 mlc), that is:

NPSHa > NPSHr + 0.5 mlc

Metering pumps

Only one clear definition of a metering

pump is given by the API675 standard: ‘A

reciprocating pump in which precise volume

control is provided by varying its effective

stroke length. Such pumps are also known

as proportioning, chemical injection, dosing

or metering pumps’.

Being a reciprocating pump, a metering

pump generates a highly pulsating flow.

Instantaneous flow variation being fluid

speed variation, this means that the pump

will have to alternately accelerate and decel-

erate the liquid column. On the suction side

of a metering pump this translates as:

At the beginning of the suction stroke, the

liquid column must be set in motion and

accelerated, which is achieved by the pump

creating a relative vacuum to pull the fluid.

At the end of the suction stroke, the

liquid column is in motion and, due to its

inertia, the pump has to decelerate it by

exerting an overpressure.

Friction losses are greatest at the middle

of the suction stroke when the speed is at

a maximum. Except for high viscosities,

friction losses do not interfere with

acceleration, as they are out of phase with

each other.

Impact on NPSH approach

The first problem is that acceleration is

largely predominant when compared to

friction losses (by a factor of more than

50 in most cases), and must be integrated

into the NPSH calculations. As a conse-

quence, pump buyers do not need to take

account of friction losses in their NPSHa

calculation.

A second problem is that acceleration is a

function both of the installation (the respon-

sibility of the buyer) and of the selected

metering pump (the responsibility of the

seller). Typically:

Acceleration = 0.016L.Q.N/d²

This formula is not a standard across all

metering pumps; each manufacturer has

its own formula, but they are all basically

equivalent. Here, L and d are respectively

the actual length (in m) and the internal

diameter (in mm) of the suction line; Q and

N are respectively the pump’s maximum

output (in litres/h) and its stroke speed

(strokes per min; spm). Note that, on the

installation side, the pipe diameter d is

squared and so has a significant influence

and, on the pump side, stroke speed N may

be a critical factor as well, since a low stroke

speed may imply a larger pump, which is

likely to be more expensive.

ISO 13710 standard

The ISO 13710 standard was published

in December 2004 and addresses ‘Recip-

rocating positive displacement pumps

for use in the petroleum and natural gas

industries’. In its NPSH section, it stipu-

lates that NPSHa is the responsibility of

the buyer, similar to the centrifugal pump

NPSH approach, and, as the standard

writers knew that there are acceleration

issues in the case of reciprocating pumps,

they simply add that NPSHa must include

acceleration losses.

The third problem is that the buyer cannot

determine the NPSHa as it is also a function

of the selected pump.

ISO 13710 also defines an NPSHr for recipro-

cating pumps, to be provided by the manu-

facturer. This NPSHr is measured in exactly

the same way as for centrifugal pumps.

This brings us to the fourth problem:

though the NPSHr approach is meaningful

in centrifugal pumps as it measures a

working point where the volumetric effi-

ciency starts to drop, therefore approaching

the point where the risk of cavitation

appears, it is not meaningful for recipro-

cating pumps. Reciprocating pumps are

supposed to deliver the same volume at

each stroke, and such a measurement

simply measures the pump’s ability to work

under starved suction conditions, what we

call the minimum positive inlet pressure

(MPIP), which is the minimum static pres-

sure on the suction side needed for the

pump to deliver its volume per stroke (see

Figure 3). It is not a sign of incipient cavita-

tion, as cavitation is caused by acceleration,

and applies to a very short period of time

at the beginning of the suction stroke,

independent of MPIP pump performances.

Illustration

Some years back, I had an intellectual

‘fight’ with a customer’s witness inspector

keen to apply the ISO 13710 NPSH

approach. The application was for liquefied

gas metering. As usual for these complex

applications, the installation was quite

simple: a suction tank pressurized at the

vapour pressure level (to maintain the

liquid phase), with a short, straight suction

line providing a flooded suction configura-

tion to the pump.

The pressure in the suction tank, minus the

vapour pressure (equalling zero at this stage),

plus the tank’s relative elevation to the pump,

minus the acceleration (not even consid-

ering friction losses) was leaving a very low

NPSHa… which was below the pump’s MPIP

reported in the datasheet. According to the

ISO 13710 NPSH interpretation:

NPSHa < NPSHr, and…

… not any metering pump can do the job!

By the way, today, this pump is working

well. Why?

First, the tank elevation was slightly larger

than the calculated acceleration, leaving

some usable energy at the pump inlet.

Second, the static pressure under which

the pump is working (the pressure in the

suction tank plus the tank elevation) was

larger – by far – than the MPIP required

by the pump. Vapour pressure does not

need to be considered here, as the pump

does not differentiate if the pressure is

coming from a liquid or a gas.

NPSH test

Another issue arises here. As for centrifugal

pumps, metering pump customers increas-

ingly want to confirm the pump selection

by an NPSH test – again, another possible

intellectual fight between the parties.

Do we want to measure the pump’s MPIP?

Easy, but, as illustrated above, it has nothing

to do with an NPSH approach whose

purpose is to prevent cavitation. Do we

want to simulate acceleration? A bit more

complex to do, but it is not a real test, as it

is a simulation based on calculations. Do we

want to really test what the seller says (that

the pump will work under the specified

conditions)? We would have to reproduce

the entire installation (!), using a fluid with

the same specific gravity, vapour pressure,

etc. Everybody can understand that this is

simply not feasible.

Conclusion

Trust is the answer! The customer has to

provide the manufacturer with the best

reliable information on the product and

the installation (usually well defined in the

datasheets). The manufacturer, for its part,

has to make the best appropriate metering

pump choice, including the NPSH criterion

approach, and give advice, such as recom-

mending enlargement of the suction pipe

diameter or shortening the pipe, suggesting

the use of a dampening device or a multi-

plex pump design, and so on.

The final, appropriate NPSH criterion for

metering pumps, which covers more than

90% of metering pump application cases, is:

NPSHa (without friction losses) >

Acceleration + 2mlc (the safety margin).

K N O W L E D G E S E R I E S

Reduce pumpingcosts through optimum pipe sizing

Every industrial facility has a piping network that carries water

or other fluids. According to the US Department of Energy

(DOE), pumping systems represent 16% of a typical facility’s

electricity costs. The power consumed to overcome the static

head in a pumping system varies linearly with flow, and very

little can be done to reduce the static component of the

system requirement. However, there are several energy- and

money-saving opportunities to reduce the power required to

overcome the friction component.

Suggested actions

systems before making an engineering

design decision.

evaluate pumping costs for at least two

pipe sizes and try to accommodate pipe

size with the lowest life-cycle cost.

your application permits, epoxy-coated

steel or plastic pipes can reduce friction

factor by more than 40%, proportionately

reducing your pumping costs.

The frictional power required depends on

flow rate, pipe size (diameter), overall pipe

length, pipe characteristics (surface rough-

ness, material, etc), and properties of the

fluid being pumped. Figure 1 shows the

annual water pumping cost (frictional power

only) for 300 m (984 ft) of pipe length for

different pipe sizes and flow rates.

Example

A pumping facility has 3000 m of piping

to carry 100 m3/h of water continuously

Based on 300 m for clean iron and steel pipes (schedule 40) for pumping 21°C water. Electricity rate – 0.05 US$/kWh and 8760 operating hours annually. Combined pump and motor efficiency – 70%.

In addition to the ANSI/HI pump standards, HI has a variety of resources for pump users and specifiers, including Pump LCC and VSP guidebooks, “7 Ways To Save Energy” training program and more. To download free executive summaries of HI’s “Pump Life Cycle Costs”, “Variable Speed Pumping”, and an index to ANSI/HI Standards, visit www.Pumps.org and www.PumpLearning.org .

Pump Systems Matter™ (PSM). Developed by the Hydraulic Institute, PSM is an educational initiative created to assist North American pump users gain a more competitive business advantage through strategic, broad-based energy management and pump system performance optimization. PSM’s mission is to provide end-users, engineering consultants and pump suppliers with tools and collaborative opportunities to integrate pump system performance optimization and efficient energy management practices into normal business operations.

PSM is seeking the active support and involvement of energy efficiency organizations, utilities, pump users, consulting engineering firms, government agencies, and other associations.

For more information on PSM, to become a sponsor, or to download PSM’s FREE Pump System Improvement Modeling Tool™ (PSIM), an educational tool designed to show pump systems engineers how modeling tools can reduce cost and conserve energy, visit www.PumpSystemsMatter.org .

US Department of Energy (DOE). DOE’s Industrial Technologies Program (ITP), through partnerships with industry, government, and non-governmental organizations, develops and delivers advanced energy efficiency, renewable energy, and pollution prevention technologies for industrial applications. ITP has launched the Save Energy Now initiative to help the nation’s manufacturing facilities continue to thrive during a time of diminished energy supplies and rising costs. As a part of this initiative, ITP is sending DOE Energy Experts to the nation’s most energy-intensive manufacturing facilities to conduct 200 Energy Savings Assessments. See www.eere.energy.gov/industry for additional information on DOE’s energy efficiency activities.

BestPractices emphasizes opportunities for savings in plant systems such as motor, steam, compressed air, and process heating systems. BestPractices is a part of the Industrial Technologies Program, and offers a variety of resources addressing ways to reduce energy and maintenance costs in industrial process systems. This includes training workshops, software tools, a series of sourcebooks, case studies, tip sheets, and other materials, including several which focus on opportunities in pumping systems. For example, the Pumping System Assessment Tool (PSAT) aids in the assessment of pumping system efficiency and estimating energy and cost savings.

to storage tanks. Determine the annual

pumping costs associated with different

pipe sizes.

From Figure 1, for 100 m3/h:

150 mm pipe: (US$725/300 m) x 3000 m =

US$7250

200 mm pipe: (US$183/300 m) x 3000 m =

US$1830

250 mm pipe: (US$50/300 m) x 3000 m =

US$500

After the energy costs are calculated, the

installation and maintenance costs should

be calculated for each pipe size. Although

the up-front cost of a larger pipe may be

higher, it may still provide the most cost-

effective solution because it will greatly

reduce the initial pump and operating costs.

General equation for estimating frictional

portion of pumping costs:

Where:

f = Friction factor (dimensionless)

Q = Flow rate (m3/h)

The friction factor, based on the pipe

roughness, pipe diameter, and the

Reynolds number, can be obtained from

engineering handbooks. For most applica-

tions, the value of this friction factor will be

0.015 to 0.0225.

Energy and demand charges: understanding your electricity bill

Thecalculations shown earlier use simpli-

fied electricity rate approximations stated

in terms of dollars per kilowatt-hour

(US$/kWh). However, electric utilities

use more complicated rate structures to

bill industrial customers. These typi-

cally include both energy (US$/kWh)

and demand charges (US$/kW), and

they have different rates depending on

the level of consumption and the time

of year. Demand charges are based on

the peak demand for a given month or

season and can have significant impacts

on some customers’ electricity costs.

When the economic impacts of efficiency

measures are calculated, the marginal

cost of the electricity needs to be

considered, taking into account energy

and demand charges, seasonal rates,

and different rates for different levels of

consumption.
