Product overview
New aftermarket A10VSO axial piston variable pump, Series 31, swashplate design for open circuit. Complete model code: A10VSO18DFR/31R-VPA12N00. Size NG18, nominal displacement 18 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: DFR pressure flow controller
In addition to the pressure controller function, an adjustable orifice (e.g. directional valve) is used to adjust the differential pressure upstream and downstream of the orifice. This is used to control the pump flow. The pump flow is equal to the actual hydraulic fluid quantity required by the consumer. With all controller combinations, the Vg reduction has priority.
- Basic position in depressurized state: Vg max.
- Setting range up to 280 bar — standard 280 bar.
- For pressure controller data, see the DR pressure controller.
