Rexroth A4vso Original Hydraulic Pump for Excavator
The A4VSO or AAVSO Axial piston pump in swash plate design for hydrostatic drives in open circuit operation
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.
We can supply model: Hydraulic axial piston pump A4VSO71, A4VSO125, A4VSO180, A4VSO250, A4VSO355, A4VSO500, A4VSO750, A4VSO1000
