Product overview
New aftermarket A10VSO axial piston variable pump, Series 31, swashplate design for open circuit. Complete model code: A10VSO71DR/31R-VPA42N00. Size NG71, nominal displacement 71 cm³/rev. Nominal pressure 280 bar, maximum pressure 350 bar. Direction of rotation R (clockwise, viewed on the drive shaft). Quality checked before shipping. Contact us to confirm exact configuration and availability before ordering.
Control: DR pressure controller
The pressure controller limits the maximum pressure at the pump outlet within the control range of the variable pump. The variable pump only supplies as much hydraulic fluid as is required by the consumers. If the working pressure exceeds the pressure command value at the pressure valve, the pump will regulate to a smaller displacement to reduce the control differential.
- Basic position in depressurized state: Vg max.
- Setting range for pressure control: 50 to 280 bar — standard 280 bar.
