Hydraulic Variable Displacement Pump A4VG Series Axial Piston Pump A4VG71HWDT1/32-NZF02KXX1E-S
Hydraulic Variable Displacement Pump A4VG Series Axial Piston Pump A4VG71HWDT1/32-NZF02KXX1E-S |
Features |
– Variable axial piston pump of swashplate design 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 important applications. |
– The service life of the shaft seal is influenced by the speed of the axial piston unit and the case drain pressure (case pressure pG). The mean differential pressure of 2 bar between the case and the ambient pressure may not be enduringly exceeded at normal operating temperature. For a higher differential pressure at reduced speed, see diagram. Momentary pressure spikes (t < 0.1 s) of up to 10 bar are permitted. The service life of the shaft seal decreases with an increase in the frequency of pressure spikes. |
