Axial Piston Variable Pump - A4VG

Perfect for different control and regulating functions, the A4VG from Bosch Rexroth features built-in pressure relief and boost valves.

Features

Variable 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 the swivel angle of the swash plate from 0 to its maximum value
Flow direction changes smoothly when the swash plate is moved through the neutral position
A wide range of highly adaptable control devices is available for different control and regulating functions
The pump is equipped with two pressure-relief valves on the high-pressure ports to protect the hydrostatic transmission (pump and motor) from overload
EThe high-pressure relief valves also function as boost valves
The integrated boost pump acts as a feed and control oil pump
The maximum boost pressure is limited by a built-in boost pressure relief valve
The integral pressure cut-off is standard
