Product overview
New aftermarket A10VSO axial piston variable pump, Series 31, swashplate design for open circuit. Complete model code: A10VSO45DFR1/31R-PSA12N00. Size NG45, nominal displacement 45 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: DFR1 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. The DFR1 version has no unloading between X and the reservoir; the LS must thus be unloaded in the system. Because of the flushing function of the flow controller in the DFR1 control valve, sufficient unloading of the X-line must also be provided.
- 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.
