Rexroth A10VSO71DFR Variable Axial Piston Pump

The Rexroth A10VSO71DFR is a variable axial piston pump for open-circuit hydraulic systems. This page covers the size 71 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.

A size 71 DFR pump with the correct control circuit

This page adds the size 71 DFR inquiry option alongside the DR, DFR1 and DFLR models. Start with the installed control function, then compare the shaft, flange and connection arrangement. A shared nominal size does not make pumps with different controllers interchangeable.

Key features

• Size 71 with DFR pressure and flow control
• Series 31 catalog reference
• Maximum geometric displacement: 71 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.

How to check the fit

• Send the machine hydraulic diagram or clear pilot-line photographs to distinguish DFR from DFR1 and DFLR.
• Compare the rotation, shaft, mounting flange, ports, seals and through-drive option with the installed unit.
• Check the hydraulic circuit, operating conditions and exact unit specifications before ordering.

Frequently asked questions

Is A10VSO71DFR 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.
