Operation Mode

Open circuit
  • Variable axial piston pump of swash plate design for hydrostatic closed circuit transmission
  • 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
