| Drive shaft | R | spline, high torque |
| Mounting flange | D | SAE 4-hole |
| Work ports | 12 | metric flange seat, fixed metric threads (DIN 13) |

Product overview
New aftermarket A10VNO axial piston variable pump, Series 53, swashplate design for open circuit. Complete model code: A10VNO85DRS/53L-VRD12K01. Size NG85, nominal displacement 85 cm³/rev. Nominal pressure 210 bar, maximum pressure 250 bar. Direction of rotation L (counter-clockwise, viewed on the drive shaft). Quality checked before shipping. Contact us to confirm exact configuration and availability before ordering.
Control: DRS pressure and flow controller (load-sensing, X-T plugged, with flushing)
In addition to the pressure controller function, an adjustable orifice is used to control the differential pressure and therefore the pump flow. The DRS version has X-T plugged with a flushing function; the LS line must be unloaded in the system. With all controller combinations, reduction of Vg has priority.
- Basic position in depressurized state: Vg max.
- Setting range up to 210 bar — standard is 210 bar.
- For pressure controller data, see the DR pressure controller.
Other control options on this size
This 85 cm³ Series 53 pump is also available with other controls:
- A10VNO85DRF/53L-VRC11N00-S — DRF pressure and flow controller (load-sensing, X-T open)
- A10VNO85DRSC/53R-VSC12N00-S — DRSC pressure and flow controller, X-T plugged without flushing
- A10VNO85ED72/53L-VRC12G70P — ED72 electrohydraulic pressure control, negative control (24 V)
- A10VNO85EP2D/53L-VWC12K04P — EP2D electro-proportional pressure control, positive control (24 V)
