Características

– Variable axial piston pump in swash plate design for hydrostatic drives in closed circuits.

– The flow rate is proportional to the drive speed and displacement.

– The flow rate can be infinitely varied by adjusting the swash plate angle.

– The flow direction changes smoothly when the swash plate passes through the neutral position.

– A wide range of highly adaptable control devices with different control and regulation functions for all important applications.

– Two pressure relief valves on the high pressure side protect the hydrostatic drive (pump and motor) from overload.

– The high pressure relief valve also serves as a boost valve.

– The integrated boost pump acts as a feed pump and controls the pressure supply.

– The maximum boost pressure is limited by the built-in low pressure safety valve.

– Integrated pressure cut-off device as standard Closed circuit
