The A4VG axial piston variable pump in 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

- The 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
