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.
