– Variable double pump A8VO with two axial tapered piston rotary groups of bent-axis design for hydrostatic drives in open circuits
– The stream is proportional to the input pace and to the displacement, and is infinitely variable from qV max to qV min =
– The pump is ideal for direct mounting on the flywheel case in diesel engines
– One particular frequent suction port for auxiliary pump and equally circuits
– A vast range of management devices is offered for diverse control and regulating functions
– Person power controller
– Integrated auxiliary pump with pressure-relief valve, optionally with further stress-reduction valve
– Electricity get-off for mounting axial piston and gear pumps
– Outstanding electrical power to bodyweight ratio
– Prolonged provider lifestyle
