Submersible Pump Unit
The up movement of hydraulic equipment types is achieved by pumping a certain volume of oil (gallons per minute or GPM) into the jack. Submersible pumps come in several sizes, and each moves a different, constant volume of oil (GPM). Submersible pumps are coupled directly to the motor with bolts. The motor turns at a constant speed (revolutions per minute or RPM). The pump is either pumping oil at full volume or not at all; it is either on or off.
