Rexroth Axial piston variable pump A4VSO Series A4VSO71 A4VSO125 A4VSO180 A4VSO250 A4VSO355 A4VSO500
Axial piston pump for rexroth A4VSO A4VSO40 A4VSO71 A4VSO125 A4VSO180 A4VSO250 A4VSO355 A4VSO500 Series Hydraulic Piston
▶ Variable displacement pump with axial piston rotary group of swashplate design for hydrostatic drives in open circuit.
▶ Diffierent mode of operation according to customer request such as DR,LR,MA,EO,HD
▶ Flow is proportional to the drive speed and displacement.
▶ Flow can be infinitely varied by adjusting the swashplate angle.
▶ Especiallysuited for the operation with HFC hydraulic fluids.
▶ Operation without external bearing flushing is possible.
▶ With selected HFC hydraulic fluids, the same pressures,
rotational speeds and bearing service life as with operation based
on mineral oil
▶ Excellent suction characteristics
▶ Low noise level
▶ Good power to weight ratio
▶ Axial and radial load capacity of drive shaft
▶ Modular layout
▶ Controls with short response time
▶ Possible through drive and pump combinations
▶ Swivel angle indicator
▶ Any mounting orientation is possible
