Rexroth A10VSO18DFR Variable Axial Piston Pump

The Rexroth A10VSO18DFR is a variable axial piston pump for open-circuit hydraulic systems. This page covers the size 18 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.

Size 18 DFR selection and pilot-line routing

For a size 18 installation, the DFR controller should be checked against the machine circuit before a replacement is quoted. The DFR and DFR1 names are close, but the reviewed Series 31 diagrams use different X-to-tank arrangements. Supply the original controller code and its connection details.

Key features

• Size 18 with DFR pressure and flow control
• Series 31 catalog reference
• Maximum geometric displacement: 18 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

• Confirm DFR on the controller nameplate and compare the X-line routing with the hydraulic diagram.
• 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 A10VSO18DFR 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.
