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 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
