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 dry valve pumps

The hydraulic pump is the element of the hydraulic system that takes mechanical energy and converts it into fluid energy in the kind of oil flow. This mechanical energy is certainly taken from what’s called the prime mover (a turning pressure) like the power take-off or directly from the truck engine.

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