A4VSO Pump

A4VS0 series is swash-plate type axial piston variable pump.It is used for open loop hydrostatic drive.The flow rate is proportional to the input speed and displacement.By adjusting the swash plate,the flow can be Infinitely regulated.The working pressure can be 350bar.The drive shaft absorbs both axial and radial loads.Short control time,long life.

Rexroth A4VSO is a variable displacement pump with an axial piston swash plate structure produced by Rexroth Rexroth, Germany. This pump is designed for use in hydraulic transmission systems, with a flow rate proportional to the driving speed and a displacement that can be infinitely adjusted. The output flow rate increases as the inclination angle of the swash plate changes from zero to the maximum value. Changing the inclination angle of the swash plate across the centerline can smoothly change the flow direction of the flow rate. This pump has excellent suction characteristics, sensitive control response, and is specially designed with long-life, high-precision aviation grade full roller bearings.
