The float free level control Liqui-Mover® pump is externally powered using 120/60/1 electrical service.
It has single-tank capacities up to 705 lpm (89,000 lbs/hr) or 40,455 kg/hr (186 gpm) and are used anywhere a conventional centrifugal pump is used, including with coils, heaters, sterilization equipment, and evaporators, to name a few applications.
Stage One: Fill
Fluid flows from the receiving chamber (A) through the inlet check valve (B) into the pump tank (C). The 3-way valve (D) is open between the pump tank and the receiving chamber, equalizing the pressure between them through the equalizing line (E).
Stage Two: Pump
When the level control (F) senses that the pump tank is full, the 3-way valve energizes to admit the motive pressure into the pump tank (C). The motive pressure forces the fluid past the discharge check valve (H) and out the discharge line.
Stage Three: Equalize
Once the level control (F) senses the pump tank has emptied, the 3-way valve (D) de-energizes, shutting off the motive pressure, and opening the vent port in the valve. This allows the pump tank (C) and the receiving chamber (A) to equalize in pressure. The cycle will now repeat.
