Axial Piston Variable Pump A4VG - Hydraulic Pump

Axial Piston Variable Pump A4 VGData sheetSeries 32 Size 28 to 250 Nominal pressure 400 barMaximum pressure 450 barClosed circuitFeaturesVariable Axial Piston pump of swashplate design for hydro- static drives in closed flow is proportional to the drive speed and displacement. The flow can be infinitely varied by adjusting the swashplate direction changes smoothly when the swashplate is moved through the neutral wide range of highly adaptable control devices with different control and regulating functions, for all important pressure-relief valves are provided on the high-pressure side to protect the hydrostatic transmission (pump and mo-tor) from high-pressure relief valves also function as boost valves.
