There are usually three types of hydraulic pump constructions found in mobile hydraulic applications. Included in these are gear, piston and vane; nevertheless, additionally, there are clutch pumps, dump pumps and pumps for refuse Hydraulic Pump china 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 can be taken from what is called the primary mover (a turning drive) such as the power take-off or straight from the pickup truck engine.
With each hydraulic pump, the pump will be of either a 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 direction.
