Axial piston unit of bent axis design with fixed displacement, for use as either pump or motor in hydrostatic drives, in open or closed circuit.
If operated as a pump, the flow is proportional to the drive speed and displacement. If operated as a motor, the output speed is proportional to the swept volume and inversely proportional to displacement. The output torque increases with the pressure drop between the high and low pressure sides.

Features:

·Equivalent with original Rexroth same model.
·High performance rotary group with well-proven spherical control area with the advantages, self-centering low peripheral speed, high efficiency.
·Robust rolling bearing endure long service life.
·Drive shaft capable of adopting radial loading.

What are the differences among plunger pump(piston pump), gear pump and vane pump?

The plunger pump（piston pump) has the highest operating pressure, variable, and high cleanliness requirements for oil. The plunger pump also has the characteristics of forced circulation, good sealing, and the outlet can not be blocked.

The gear pump has the advantages of convenient maintenance, simple structure and long service time. Compared with vane pump and plunger pump(piston pump), gear pump has strong anti pollution ability.

The vane pump has the advantages of smooth movement, compact structure, even flow, small noise and even output flow. The efficiency is between gear pump and plunger pump(piston pump), which is mostly used in the hydraulic system of machine tool, hydraulic press, vehicle, engineering machinery and plastic injection machine
