A4VSO swash plate structure axial piston variable pump is suitable for hydrostatic transmission in open circuits, and the flow rate is proportional to the transmission speed and displacement.
By adjusting the angle of the swash plate, stepless changes in flow rate can be achieved, with excellent oil suction performance and low noise levels.
Rexroth A4VSO A4VO piston pump provides long service life and axial and radial load capacity of the drive shaft while providing an ideal power-to-weight ratio.
Piston pump features a modular design with variable shaft drive options and a visual rotation angle indicator.
The installation position can be changed freely and is suitable for variable speed drives.
HF mode is available to reduce data volume, and a special version of HFC mode is also available.
