Series 6 Size Nominal pressure/Maximum pressure 28 to 180 400/450 bar 250 to 355 350/400 bar Open and closed circuits
Features
– Fixed plug-in motor with axial tapered piston rotary group of bent-axis design, for hydrostatic drives in open and closed circuits
– Far-reaching integration in mechanical gearbox due to recessed mounting flange loed in the center of the (extremely space-saving construction) – The output speed is dependent on the flow of the pump and the displacement of the motor
– The output torque increases with the pressure differential between the high-pressure and the low-pressure side.
– Small dimensions
– High total efficiency
– Complete unit, ready-assembled and tested
– Easy to install, simply plug into the mechanical gearbox
– No configuration specifiions to be observed when installing
