There are usually three types of hydraulic pump constructions found in mobile hydraulic applications. Included in these are equipment, piston and vane; nevertheless, there are also clutch pumps, dump pumps and pumps for refuse vehicles such as for example dry valve pumps

The hydraulic pump is the component of the hydraulic system that takes mechanical energy and converts it into fluid energy in the form of oil flow. This mechanical energy is usually taken from what is called the primary mover (a turning force) such as the power take-off or directly from the pickup truck 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 Hydraulic Pump china operate in one direction of shaft rotation. On the other hand, a bi-rotational pump has the ability to operate in either direction.
