Product overview
New aftermarket A10VSO axial piston variable pump, Series 32, swashplate design for open circuit. Complete model code: A10VSO71DRG/32R-VPB12N00-S. 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: DRG pressure controller, remotely controlled
For the remotely controlled pressure controller, the LS pressure limitation is performed using a separately arranged pressure relief valve. Therefore any pressure control value under the pressure set on the pressure controller can be regulated. A pressure relief valve is externally piped up to port X for remote control; this relief valve is not included in the scope of delivery of the DRG control.
- Basic position in depressurized state: Vg max.
- Setting range for pressure control: 20 to 280 bar — standard 280 bar.
- Setting range for differential pressure: 10 to 22 bar — standard 20 bar (a standard setting of 20 bar Δp results in a pilot oil flow of approx. 1.5 l/min at port X).
- As a separate pressure relief valve we recommend a direct operated, hydraulic or electric proportional one; the maximum line length should not exceed 2 m.
- Unloading port X to the reservoir results in a zero stroke (standby) pressure which is approx. 1 to 2 bar higher than the defined differential pressure Δp.
