Product overview
New aftermarket A10VO axial piston variable pump, Series 52, swashplate design for open circuit. Complete model code: A10VO45DFR1/52R-PSC64N00. Size NG45, nominal displacement 45 cm³/rev. Nominal pressure 250 bar, maximum pressure 315 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 and flow controller (load-sensing, with flushing)
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 from X to 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 250 bar — standard is 250 bar.
- For pressure controller data, see the DR pressure controller.
Other control options on this size
This 45 cm³ Series 52 pump is also available with other controls:
