Hydraulic A4VG series Variable Displacement Piston Pump

A4VG Series is variable axial piston pump for hydrostatic drives in closed circuit.
– The flow is proportional to the drive speed and displacement.
– The flow can be infinitely varied by adjusting the swashplate angle.
– Flow direction changes smoothly when the swashplate is moved through the neutral position.
– A wide range of highly adaptable control devices with different control and regulating functions, for all importantapplications.
– The high-pressure relief valves also function as boost valves.
– The integrated boost pump acts as a feed pump and controlpressure supply.
– The maximum boost pressure is limited by a built-in lowpressure relief valve.
