– The variable displacement axial piston pump type A4VSO in swashplate design is designed for open circuit hydrostatic drives.
– The flow is proportional to the input drive speed and displacement. By adjusting the swashplate it is possible to infinitely vary the flow. – Slot-controlled swashplate design
– Infinitely variable displacement
– Good suction characteristics
– Permissible nominal operating pressure 350 bar
– Low noise level
– Long service life
– Drive shaft capable of absorbing axial and radial loads
– Good power/weight ratio
