Features

Variable axial piston pump of swashplate design for hydrostatic drives in closed circuit
– The flow is proportional to the drive speed and displacement.
– The flow can be infinitely varied by adjusting the swashplate angle.
– Flow direction changes smoothly when the swashplate is moved through the neutral position.
– A wide range of highly adaptable control devices with different control and regulating functions, for all important applications.
– Two pressure-relief valves are provided on the high-pressure side 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 pump and control pressure supply.
– The maximum boost pressure is limited by a built-in low-pressure relief valve.
– High pressure level for high power density and good efficiency
