There are typically three types of hydraulic pump constructions within mobile hydraulic applications. Included in these are equipment, piston and vane; however, there are also clutch pumps, dump pumps and pumps for refuse automobiles such as dry valve pumps

The hydraulic pump may be the component of the hydraulic system that takes Hydraulic Pump china mechanical energy and converts it into fluid energy in the kind of oil flow. This mechanical energy is certainly taken from what is called the prime mover (a turning pressure) like the power take-off or straight from the vehicle engine.

With each hydraulic pump, the pump will be of the uni-rotational or bi-rotational design. As its name implies, a uni-rotational pump is made to operate in one path of shaft rotation. On the other hand, a bi-rotational pump has the capacity to operate in either direction.
