Data sheet
Series			10, 11 and 30
Size			40 to 1000
Nominal pressure			350 bar
Peak pressure			400 bar
Features
– Axial piston pump in swash plate design for hydrostatic drives in open circuit operation
– The flow is proportional to the input drive speed and displacement. By adjusting the swash plate angle it is possible to infinitely vary the output flow.
– Excellent suction characteristics
– Low noise level
– Long service life
– Modular design
– Short response times
– Variable through drive options
– Visual swivel angle indicator
– Optional mounting position
– Operation on HF-fluids under reduced operational data possible
