Rexroth A10VSO45DFR Variable Axial Piston Pump

The Rexroth A10VSO45DFR is a variable axial piston pump for open-circuit hydraulic systems. This page covers the size 45 DFR model with Series 31 catalog reference data. DENGFENG accepts inquiries for original new Rexroth products and confirms the exact configuration, condition and availability for each quotation.

Check the series before selecting a size 45 DFR pump

Size 45 DFR inquiries need a clear series code as well as the controller designation. This page uses Series 31 reference data. A different series on the installed unit requires its own dimensional and operating checks, even where the base model looks similar.

Key features

• Size 45 with DFR pressure and flow control
• Series 31 catalog reference
• Maximum geometric displacement: 45 cm³/rev
• Nominal pressure: 280 bar (catalog reference)
• Original Rexroth product inquiry; exact unit confirmed in the quotation

Controller function

DFR provides pressure and flow control. In the reviewed design the X-to-tank connection is open. Pressure control takes priority when the pressure limit is reached. Confirm the control-line arrangement against the applicable hydraulic diagram.

Model and configuration

Technical values below refer to the standard Series 31 design. They do not identify a complete orderable unit. Confirm the specifications separately for special versions and other series.

Maximum pressure is not a continuous-duty setting. Confirm the applicable operating limits for the exact supplied unit.

Frequently asked questions

Is A10VSO45DFR a complete ordering code?

No. It identifies a size and controller combination. Send the full nameplate code, including the series and all suffixes, so the exact configuration can be quoted.

Are price and stock shown on this page?

Price, condition, availability and delivery are confirmed individually after the complete model and quantity are reviewed.

How does DFR differ from DFR1?

Both provide pressure and flow control, but the reviewed designs differ in their X-to-tank connection. DFR has an open connection. Confirm the series-specific hydraulic diagram and unloading arrangement before considering a change.
