Liqui-Mover® Pumps

2

Kadant Johnson has been manufacturing the Liqui-Mover® pump since 1934. The Liqui-Mover pump performs the same function as a conventional electric centrifugal pump. However, it is based on a different operating concept and has fewer moving parts than aconventional electric pump.

The Liqui-Mover pump is a positive displacement pump and has no motors, starters, rotating mechanical seals, or impeller. Instead,the Liqui-Mover pump uses steam (or other compatible inert gas) as the motive pressure to lift or pump liquids.

Liqui-Mover pumps have few temperature limitations, unlike conventional electric pumps. Many conventional pumps are limited to liquid temperatures of 200°F. Because of the Liqui-Mover pump’s high temperature capabilities, flashing valuable heat energy toatmosphere or adding additional cooling equipment can be eliminated, increasing system reliability and reducing installation andequipment costs.

Due to their simple design and compact dimensions, Liqui-Mover pumps are easy to integrate into new and existing systems. Theyare easy to install and may require only a single trade to install. Models are available as a packaged unit (LRSM model) ready fordirect hook-up to plant piping.

The Liqui-Mover pump is available with a non-electric float or a float-free level control with capacities up to 180,000 pph (360 gpm).

Stage 1: Fill stage

Fluid flows from the receiving chamber(A) through an inlet check valve (B)into the pump tank (C), raising a float(D). The vent port (E) is open toequalize pressure between thereceiving chamber and pump tank.

When the float reaches its highestlevel, it triggers a linkage (F) that closesthe vent port and opens the motivepressure valve (G) to admit the motivepressure into the pump tank. Themotive pressure forces the fluid pastthe discharge check valve (H) and outthe discharge line.

Once the float (D) reaches its lowestposition, the linkage shuts off themotive pressure port, and opens thevent port (E). Excess pressure is ventedto the receiver, equalizing pressurebetween the two tanks. The cycle willnow repeat.

Stage 2: Pump stage Stage 3: Equalize stage

Types of systems

Open systemAn open system is intended for usewith mixed return pressures, thisdesign requires no supplementalcooling of condensate.

Flash systemA flash system is for applicationsrequiring flash steam – such as highpressure processing equipment – thereceiver in this design acts as a flash tank.

Closed systemA closed system is for single steam users.There is no BTU energy loss fromflashing.

Open coil designThe Kadant Johnson float assembly has open coil springs in its mechanism. With the open coil design, active coils can not touch.This prevents the active coils from hammering into each other and flattening, which could weaken the springs to the point ofbreakage. The open coils also prevent deposits from being trapped between the active coils, which could cause etching andbreakage of the coils.

Reinforced floatThe weakest area of conventional floats is where the float arm attaches to the ball. The Kadant Johnson float ball has a thickerwall in this area to provide additional support.

Do you have temperature or modulated steam control valveson steam coils or heat exchangers? Do you experience any ofthe following symptoms?

u Flooded heat exchangers or steam coilsu Frozen steam coils or air handlersu Water hammer in heat exchangers or steam coilsu Damaged tube bundlesu Poor temperature control in heat exchangersu Poor temperature control in steam coils or air handlers

Insufficient differential pressure across a steam trap will notallow condensate to drain properly (see Figure 1). This iscommonly known as a “stall” condition.

The Kadant Johnson solution is to install a PumpTrap (seeFigure 2). A PumpTrap should be installed on a single steamcoil or heat exchanger, never multiple steam users. A properly sized steam trap has been installed at the outlet of the Liqui-Mover pump. The steam trap operates normallywhen there is enough system pressure to overcome the backpressure. When the system pressure becomes equal to or lessthan the back pressure, the Liqui-Mover pump will pump thecondensate through the steam trap and into the overheadreturn line. Steam should always be used as the motivepressure.

Energy Loss

18

Vented or flash steam contains valuable heat energy. If theflash steam can be captured, utilized, and returned to theboiler, your total steam generation costs may be reduced.This includes a reduction in make-up water, treatmentchemicals, and possibly sewer costs.

Operating conditions:A. Condensate pressure: 50 psig flashing to 0 psig

B. Condensate load: 10,000 lb/hr

C. Cost of steam: $5.00 per 1,000 lb

D. Specific volume of water: 0.120 gal/lb (40°F to 60°F)

E. Make-up water and chemical cost: $5.00 per 1,000 gallons

F. Hours of operation (annually): 6,000 hours

CalculationsEstimated Steam Loss:

1. Flash loss = 9%

See chart below.

2. Lb/hr loss = B x flash loss

10,000 x 9% = 900 lb/hr

3. Lb/year loss = F x 900 lb/hr

6,000 x 900 = 5,400,000 lb/year

4. $ loss/year = lb/year x C

5,450,000 x $5.00 = $27,000 loss/year1,000

Estimated water loss:

5. Gal/year of make-up water = lb/year loss x D

5,400,000 x 0.120 = 648,000 gal/year

6. $ water loss/year = gal/year x E

648,000 x $5.00 = $3,240 loss/year1,000

Total estimated dollar loss (Step 4 + Step 6):

$27,000 + $3,240 = $30,240
