A4VG56 Rexroth Series A4VG28 A4VG40 A4VG45 A4VG56 A4VG71 A4VG90 Hydraulic Piston Variable Pump

A4VG Variable Displacement Axial Piston Pump of swash plate design for hydrostatic closed circuit transmissions. Flow is proportional to drive speed and displacement and is infinitely variable. Output flow increases with swivel angle from 0 to its maximum value.

* Variableaxial piston pump of swashplate design for hydro- static drives in closed
* The flow is proportional to the drive speed and
* Theflow can be infinitely varied by adjusting the swashplate angle.
* Flow direction changes smoothly when the swashplateis moved through the neutral
* A wide range of highly adaptable control devices with differentcontrol and regulating functions, for all important
appliCATEEions.
* Two pressure-relief valves are provided on the high-pressure side to protect the hydrostatic transmission (pump and mo- tor) from
* The high-pressure relief valves also function as boost
* The integrated boost pump acts as a feed pump and control pressure
* Themaximum boost pressure is limited by a built-in low- pressure relief
* As standard with integrated pressurecut-off
