A4VSO
Xeriwell or Others
Rexroth A4VSO is a variable displacement pump with an axial piston swash plate structure. 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. In addition, it also has low noise, long lifespan, excellent power and weight ratio, and the through shaft structure can be stacked into a combination pump.
Rexroth A4VSO Piston Pump Features:
1) Through drive for mounting of further pumps up to same nominal size
2) Axial piston pump in swash plate design for hydrostatic drives in open circuit operation
3) The flow is proportional to the input drive speed and displacement. By adjusting the swash plate angle it is possible to infinitely vary the output flow.
4) Excellent suction characteristics
5) Low noise level
6) Robust pump with very long service life
7) Modular design
8) Short control response times
9) Variable through drive options
10) Visual swivel angle indicator
11) Optional mounting position
12) Operation on HF-fluids under reduced operational data possible
13) Robust high pressure pump for industrial applications
14) Nominal pressure 350 bar
15) Maximum pressure 400 bar
16) Open circuit
