5.4 Electrical connection

The electrical connection should only be carried out by a qualified electrician.

Warning!An incorrect electrical connection can result in fatal injury.Carry out connection work according to DIN VDE 0100; also comply with DIN VDE 0165 in potentially explosive atmospheres.

The earth, neutral connection, residual current circuit brea-ker, etc. must- correspond to the directives of the local public utility com-

pany (PUC) and- function flawlessly according to the electrician's inspection.

The cross-section and voltage drop of the supply line must comply with the respective regulations.

Caution!Impermissible heating will damage the three-phase motor.Comply with the voltage tolerance of ± 5% according to DIN EN 60034-1. In standard motors (with no explosion protection) a tolerance of ± 5% also applies for the voltage range.

Warning!Electric current can result in fatal injury.Provide equipotential bonding between the pump casing and the building earth.

5.5 Motor protection

Use a motor circuit breaker or adequate motor protection with a tripping characteristic according to DIN VDE 0660.Accommodate the integrated temperature monitors in the motor control circuits in such a way that if the temperature monitor responds it results in switching off the motor.


23

Important!The motor circuit breaker should be - regulated for nominal motor current during direct starting,- introduced into the delta link for star-delta starting and set

to a maximum of 0.58-times the nominal current.

Motors with an additional PTC thermistor installed as stan-dard (see section 5.7.1 PTC thermistor connection).

Warning!If the installed winding protection trips, it can result in a potentially fatal explo-sive atmosphere. Do not reactivate the system without first checking it and eliminating the cause of the disturbance.

5.6 Direction of rotation check

Make sure you check the direction of rotation during the initial commissioning procedure and also at each new installation location of three-phase pumps. An incorrect direction of ro-tation will result in decreased pump power output, and may damage the pump.

Danger!The rotating impeller can cut or crush people's hands and arms.Secure the pump when checking the direction of rotation.Do not reach into the pressure flanges or the intake port of the pump casing.

Danger!Risk of a potentially fatal explosion during the installation phase. Provide a constant supply of pumped media to the supply and pressure pipes as well as to the interior of the pump that is in contact with the liquid. Provide appropriate monitoring measures to ensure this.Only then should you check the direc-tion of rotation.

Caution!Dry running the pump will destroy the mechanical seal! After starting up the pump, switch it off again immediately.

It is possible to activate the pump temporarily (without ex-plosion protection) for 3 seconds max. without the risk of dry running.Each pump is to be inspected individually for control systems with multiple pumps.

The direction of rotation corresponds to the rotation indicator arrow!

Important!This must rotate clockwise when facing the motor fan.


24

5.6.1 Changes in direction of rotation

Change the direction of rotation by swapping two phases of the feed cable in the control system.

5.7 Motor connection diagrams

Caution!An incorrect electrical circuit arrange-ment will result in breakdown of the three-phase motor.Observe the circuit arrangement.

To the tripping unit

Important!- Measurement voltage of max. 2.5 V DC!- Only operate in conjunction with a tripping unit.- Use a measuring bridge or ohmmeter to check the resi-

stance.- Assignment of terminals A1 and A2 (if present) in the event

of a PTC thermistor breakdown.

5.8 Frequency converter operation

Important!Do not use frequency converters in explosion-proof areas.

A frequency converter can also be connected to all motors in a direct mounting configuration. The potential ability to regulate the frequency of the pumps in the range 30 to 50 Hz (30 to 60 Hz) is dependent on the operating conditions.

Important!Frequency converters must comply with the EU low voltage and EMC directives.

Use AC/DC-sensitive residual current circuit breakers if necessary.

5.9 Laying the pipelines

Lay the pressure pipes in accordance with the applicable regulations and relevant accident prevention regulations.

Warning!Escaping hot pumped media is poten-tially fatal. Do not exceed the pipeline forces.

Ensure measures are in place for complete ventilation during the laying procedure.Pressure pipe- lay frost-free,- secure and- connect so they are stress-free.Pipe forces and moments must not affect the pump.

Install a ...- gate valve immediately upstream of the pump to close

off the pipes. This makes it possible to remove the pump when the pipes are full.

- non-return valve between the pressure flange and the gate valve. This prevents the pumped medium from flowing back after shutting off the pump and also avoids liquid slugging.

5.10 Frost protection

Notice!The effects of frost can damage the pump when full. Drain pumps during prolonged periods of inactivity.

Caution!Escaping pumped media can cause burns to hands and arms.Depressurise the pump casing. Only then should you drain the pump.

Commissioning

26

6 CommissioningInspect the pump before commissioning and carry out a functional check. When doing this, pay special attention to the following:

- Turn the motor shaft several times by hand.

- Never allow the pump to run dry.- Have the pump and all the pipelines been

properly connected?- Has the electrical connection been carried

out in accordance with the applicable re-gulations?

- Is the temperature monitor connected (if present)?

- Is the motor circuit breaker set correctly?- Is the pump's direction of rotation also cor-

rect when it is operated via an emergency generator?

- Are the gate valves that are required for operation open?

- Is the pump mounted securely?- Are the inlets and outlets of the pumping

station secure, and have they been in-spected?

Caution!A hot pump casing and hot cleaning port can burn hands and arms.Do not touch pumps that deliver hot water. Take precautionary measures to pre-vent burning.

Caution!Dry running the pump will destroy the mechanical seal! Before starting the pump, fill it and the supply pipe with the pumped medium. Then, de-aerate.


Important!Alternately operate installed reserve pumps using the con-troller. This ensures the operational readiness of the pumps.

6.1 Operating modes and connecting frequency

All models are designed for operating mode S1 (continuous operation) with a filled pump.

Notice!Prolonged operation against closed gate valves heats up the pumped medium and the pump.Open the gate valves before operation.

Danger!Operating the pump with closed shut-off valves creates a potentially fatal and explosive atmosphere.Open the gate valves before operation.

Commissioning

27

Important!Use a motor circuit breaker or appropriate motor protection with a tripping characteristic according to DIN VDE 0660.

Do not exceed ten starting procedures per hour. This pre-vents a sharp increase in temperature in the motor and an excessive load on the pump, motor, seals and bearings. Contact the respective manufacturer with regard to the per-missible frequency of starting for possible starter devices.

6.2 Starting up

To start the pump:1. Close the gate valves and shut-off cocks

of the manometer2. Switch on the motor3. Open the shut-off cocks of the manometer.

Only open the gate valves slightly if the pressure pipe is empty. If the pipe is full, open until the permissible motor load is reached (compare the ammeter display with the specifications on the motor name plate!)

Maintenance/cleaning

28

7 Maintenance/CleaningThe content and structure of this maintenance manual is based on DIN 31052 "maintenance".Maintenance and cleaning work should only be carried out by specialist personnel. These personnel must be provided with personal protective equipment (e.g. protective gloves).

Important!According to EN 60204-1, a person is understood to be a specialist if they- are able to use their professional training, knowledge and

experience as well as knowledge of the relevant standards to assess the work they have been tasked with and

- are also able to identify any potential dangers.

Important!Before maintenance and cleaning work, you must observe section 3.5 “Shut-off procedures”.Only use appliances and tools that are expressly intended for this work.

Clean and maintain the pump at regular intervals. This will ensure trouble-free operation of the pump.

Danger!The rotating impeller can cut or crush people's hands and arms.Allow the impeller to come to a complete standstill.Secure the pump to prevent it from rolling and tipping over.

Notice!Pumped media can be hazardous to people's health. Always wear personal protective equipment such as protec-tive gloves and goggles.

The pump is subject to vibrations during operation that can loosen the screw and clamp connections. Inspect the pump at regular intervals for any loose connections (recommendation is every 6 months for single-shift operation). Remove any dust deposits and impurities on a regular basis.

Caution!Injuries may be caused when maintai-ning and cleaning the pump.Observe the safety regulations and the generally recognised “codes of practice”.

7.1 Maintenance

When carrying out maintenance and repair work, watch out for:- crushing hazards and- dangers due to electric current.

Decontaminate the pump after pumping any media that are hazardous to health.

Important!Only authorised workshops/people are allowed to work on explosion-proof pumps while using original manufacturer parts.Otherwise, the explosion protection certificate will be ren-dered invalid.

Danger!Flying sparks may cause a potentially fatal explosion.Before dismantling the pump in po-tentially explosive atmospheres, make sure that the structure is adequately aerated.If the pump has been dismantled, carry out extensive repair and maintenance work at a separate location.


29

Warning!When removing the pump from the pipe network, there is a risk of tipping which can result in serious injury.Secure the pump during transportation using appropriate separate lifting ac-cessories. Only set down the pump on a sufficiently sturdy surface that is level in all direc-tions. Also secure it to prevent it from tipping over.

Important!Collect any waste and emissions in appropriate containers and dispose of them properly.

7.2 Maintenance instructions during prolonged peri-ods of inactivity

Protect the pumps from exposure to the weather (UV rays, sunlight, high humidity levels, frost, etc.).The points in section 6 ‘Commissioning’ must be fulfilled before recommissioning the pumps.

Caution!Insufficient rotary motion of the motor shaft leads to the impeller jamming and to a failure of the mechanical seal. To counteract this, rotate the motor shaft several times by hand at weekly intervals.

In addition, the following label can be found on the motor:

Figure 6 Dry running label

The label tells you that the motor shaft should be turned several times by hand at weekly intervals and that the ope-rating instructions should be observed!

Follow the instructions on the label.

Danger!A failure of the mechanical seal can create a potentially fatal explosive atmosphere. Ensure proper functioning of the me-chanical seal by monitoring it regularly.

For pump controllers, it is recommended to programme an automatic start up every 48 hours for a maximum of 3 seconds.A start up procedure at approximately 5 Hz is advisable for operation with frequency converters.

7.3 Bearing lubrication

Anti-friction bearings are supplied pre-lubricated.


30

7.4 Seals

In general, a mechanical seal does not require any main-tenance.Only replace the mechanical seal as a complete unit. This ensures optimum shaft sealing.

Danger!A failure of the mechanical seal can create a potentially fatal explosive atmosphere. Ensure proper functioning of the me-chanical seal by monitoring it regularly.

If monitoring units are installed for the mechanical seal, check their function.

Danger!Leaky static seals can create a potenti-ally fatal explosive atmosphere. Check the leak tightness of seals at regular intervals.

7.5 Cleaning

Remove any sediment deposits when disassembling or dismantling the pump using mechanical means if necessary. Doing this will ensure flawless operation.Before decommissioning and storing the pump after a prolon-ged period of operation, flush it thoroughly with clear water and then clean it carefully. Hardened dirt deposits, limescale etc. can block the impeller and the motor shaft.When cleaning centrifugal pumps that are used in the food industry or in the supply of drinking water, use an appropriate disinfectant or cleaning agent.

Important!Anti-friction bearings that are used at a speed of- 3000 (3600) rpm are to be re-lubricated or replaced, if

necessary, after 10,000 hours of operationor every 3 years at the latest.

Danger!Insufficient lubrication of the anti-fricti-on bearings in the explosion protection zone can result in a potentially fatal explosive atmosphere. Replace anti-friction bearings that run at a speed of 3000 (3600) rpm after every 10,000 hours of operation.

Warning!Lubricant is hazardous to health.Do not swallow lubricant.

Important!- The grease type for re-lubrication is "Staburags NBU 8

EP" made by Klüber Lubrication München KG.- Do not over-lubricate the bearings.- Dispose of any lubrication properly.

When using in service water or untreated water, contact the manufacturer with regard to lubrication selection.

Loosen the connecting bolts from the block motor (802) and intermediate casing (113).

9.

Pull the intermediate casing (113) over the motor shaft (819).

10.

Notice!A damaged fitting surface does not guarantee a precise seal.Do not damage the seating for the O-ring.

Remove all components of the mechanical seal (433) from the intermediate casing (113).

11.

Clean the chrome-nickel steel motor shaft of any residue and sediment deposits using an ultra-fine emery cloth.Clean any deposits from the seating for the O-ring.

Important!Replace any seals that have been removed. This ensures continued precise sealing.

9.2 Assembly

Before starting to reassemble the pump, all of the dismantled parts must be- checked for signs of damage and wear,- cleaned and- replaced with original spare parts if necessary.

Important!Nuts (920) with a self-locking plastic ring must be replaced when reattaching the impeller.

Important!To reduce friction during assembly, lubricate all the sliding surfaces of the elastomers with low surface tension water (added detergent). Warning - do not use oil or grease!

1.

When inserting the pressure-sensitive counter ring, ensure- an even distribution of pressure,- you use a clean pin with a soft seating and- that there are no foreign particles on the sliding surfaces.

Insert the counter ring with the O-ring into the interme-diate casing (113) by hand.

2.

Slide assembly aids (acces-sories) onto the motor shaft (819) (if available).

3.

Important!Do not damage the counter ring of the mechanical seal on the thread and transition of the motor shaft or press it at an angle!

Carefully slide the interme-diate casing (113) over the motor shaft (819) and onto the centering of the block motor (802).

4.

Screw the intermediate ca-sing (113) to the block motor (802).

Important!- Make sure you degrease the shaft surface!- Pre-tensioning of the spring is achieved by installing the

impeller.

5.

Carefully slide the rotating sliding ring with bellows and spring over the motor shaft shoulder and up to the inte-grated counter ring using a screwing motion.

6.

Use assembly aids (accesso-ries) (if available) to ensure an optimal seating of the mechanical seal on the motor shaft (819).

7.

Insert the key (940) into the motor shaft groove.

8.

Slide the impeller (230) onto the motor shaft (819).

9.

Slide the washer (554) onto the motor shaft (819).

10.

Tighten the nut (920).

11.

Important!Turn back jack screws beforehand.

Place the gasket (400.1) bet-ween the pump casing (101) and the intermediate casing (113). Then insert the com-plete interchangeable module into the centering of the pump casing.

12.

Important!- Too large an air gap significantly reduces the performance

of the pump.

Air gap setting for open multi-vane impellers:- Air gap between the front side of the blade and the mating

surface of the pump casing: 0.3 - 0.5 mm.- Check with a depth gauge

1.) Impeller gap too narrow:Place a second gasket (400.1) between the pump casing (101) and the intermediate casing (113) if the impeller (230) runs in the opposite direction on the pump casing (101).

2.) Impeller gap too wide:Place a shim behind the impeller (230) to compensate for the air gap.

13.

Screw the pump casing (101) to the intermediate casing (113).


39

Important!- Check that the impeller (230) can run freely by turning it!- Carry out the electrical connection of the block motor (see

section 5.4 'Electrical connection')!• Observe the connection type (refer to the name plate

on the motor) • Observe the "clockwise" direction of rotation (see section

5.6 'Direction of rotation check')

Start up the pump unit (see section 6 ‘Commissioning’).
