Baile Hydraulic AA4VG28 AA4VG40 AA4VG56 Rexroth Axial Piston Variable Pump

Features – Variable axial piston pump of swashplate 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 swashplate from 0 to its maximum value – Flow direction changes smoothly when the swashplate 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 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
