A15VSO
Xeriwell or Others
Rexroth A15VSO axial Piston Variable Hydraulic Pump is developed for industrial applications, which requires high-pressure performance in open circuits.solid and highly effective option. Their flowis proportional to the drive speed and displacement, and the flow can be infnitely varied by controlling the swashplate angle.
The pump can work either self-priming or with a charge pump, which makes Rexroth A15VSO to a multi-purpose and versatile solution, used in a wide range of industrial applications such as tooling machines. The charge pump (impeller) is a centrifugal pump withwhich the pump is filled and can be operated at higher rotational speeds.
Rexroth A15VSO is a compact, high-efficiency pump with a universal through-drive that allows it to be 100% through-driven and can be added to other axial pistonpumps/gear wheel pumps of the same size. It comes in diameters ranging from 110to 280 and can withstand maximum pressures of 420 bar in addition to nominalpressures of 350 bar. Due to high power density and lownoise level, these pumps performs well in industrial applications.
Features:
1) Variable axial piston pump of swashplate design for hydrostatic drives in open circuit.
2) For use preferably in stationary applications.
3) The flow is proportional to the drive speed and displacement.
4) The flow can be infi nitely varied by adjusting the swashplate angle.
5) The pump can work either self-priming or with a charge pump.
6) A wide range of highly adaptable control devices with different control and regulating functions for stationary applications.
7) 100% mooring function possible depending on specific controller (overcenter, operation as a motor).
8) The universal through drive is suitable for adding gear pumps and axial piston pumps up to the same size, i.e. 100% through drive.
9) Compact design
10) High effi ciency
11) High power density
12) Low noise level
