1 Operated Pumps Liqui-Mover pump products Non-electric positive displacement pumps. The more reliable and efficient way to move liquids.

2 Liqui-Mover Pumps Kadant Johnson has been manufacturing the Liqui-Mover pump since 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 a conventional 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 to atmosphere or adding additional cooling equipment can be eliminated, increasing system reliability and reducing installation and equipment costs. Due to their simple design and compact dimensions, Liqui-Mover pumps are easy to integrate into new and existing systems. They are easy to install and may require only a single trade to install. Models are available as a packaged unit (LRSM model) ready for direct 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).

4 Operation series Liqui-Mover pumps The float series Liqui-Mover pump moves condensate and other fluids using steam or other inert gases under pressure without motors, pumps, rotors, or electricity. Stage 1: stage Stage 2: Pump stage Stage 3: Equalize stage A E G E D C B H F D 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 to equalize pressure between the receiving chamber and pump tank. When the float reaches its highest level, it triggers a linkage (F) that closes the vent port and opens the motive pressure valve (G) to admit the motive pressure into the pump tank. The motive pressure forces the fluid past the discharge check valve (H) and out the discharge line. Once the float (D) reaches its lowest position, the linkage shuts off the motive pressure port, and opens the vent port (E). Excess pressure is vented to the receiver, equalizing pressure between the two tanks. The cycle will now repeat.

Flash system A flash system is for applications requiring flash steam such as high pressure processing equipment the receiver in this design acts as a flash tank. Closed system A closed system is for single steam users. There is no BTU energy loss from flashing. 4

Open coil design The 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 of breakage. The open coils also prevent deposits from being trapped between the active coils, which could cause etching and breakage of the coils. Reinforced float The weakest area of conventional floats is where the float arm attaches to the ball. The Kadant Johnson float ball has a thicker wall in this area to provide additional support.

16 PumpTrap System Do you have temperature or modulated steam control valves on steam coils or heat exchangers? Do you experience any of the following symptoms? u Flooded heat exchangers or steam coils u Frozen steam coils or air handlers u Water hammer in heat exchangers or steam coils u Damaged tube bundles u Poor temperature control in heat exchangers u Poor temperature control in steam coils or air handlers P4 To D.A. tank (5 psig) Lift Condensate header Steam trap P3 Air vent Vacuum breaker Heat exchanger P2 Temp. control valve T2 T1 P1 Steam supply Insufficient differential pressure across a steam trap will not allow condensate to drain properly (see Figure 1). This is commonly known as a stall condition. Figure 1 The Kadant Johnson solution is to install a PumpTrap (see Figure 2). A PumpTrap should be installed on a single steam coil 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 normally when there is enough system pressure to overcome the back pressure. When the system pressure becomes equal to or less than the back pressure, the Liqui-Mover pump will pump the condensate through the steam trap and into the overhead return line. Steam should always be used as the motive pressure.

18 Energy Loss Vented or flash steam contains valuable heat energy. If the flash steam can be captured, utilized, and returned to the boiler, your total steam generation costs may be reduced. This includes a reduction in make-up water, treatment chemicals, 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: 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 Calculations Estimated 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/year 1,000 Estimated water loss: 5. Gal/year of make-up water = lb/year loss x D 5,400,000 x = 648,000 gal/year 6. $ water loss/year = gal/year x E 648,000 x $5.00 = $3,240 loss/year 1,000 Total estimated dollar loss (Step 4 + Step 6): $27,000 + $3,240 = $30,240 Percentage flash generated Inlet Condensate psig Flash Tank psig
