Description: Hydraulic pumps produce pressure in hydraulic system, which enables movement of hydraulic actuators (including cylinders). Gear pumps are one type of hydraulic pumps which are made out of 2 gears which generate the hydraulic pressure on output port. Hydraulic gear pumps are usually connected to electric motors with a shaft which turns the gears inside the pump. Each gear pump has a fixed amount of fluid which it can move from input port to output port in one revolution. This quantity of fluid is called displacement of gear pump.

Usage: Hydraulic gear pumps are used in agricultural machinery (like tractors) , industrial machinery, lifting equipment (like forklifts) and other heavy machinery which uses hydraulic systems to move, crush or lift objects.
