The Rexroth A10VSO28DFR1 is a variable axial piston pump for open-circuit hydraulic systems. This page covers the size 28 DFR1 model with Series 31 catalog reference data. DENGFENG accepts inquiries for original Rexroth products and confirms the exact configuration, condition and availability for each quotation.

Size 28 pump for pressure and flow control

The A10VSO28DFR1 is a useful reference for a size 28 pump inquiry where flow demand and pressure control must both be checked. The full suffix is needed to distinguish seals, drive shaft, mounting and connection details.

Key features

Size 28 with DFR1 pressure and flow control
Series 31 catalog reference
Maximum geometric displacement: 28 cm³/rev
Nominal pressure: 280 bar (catalog reference)
Original Rexroth product inquiry; exact unit confirmed in the quotation

Controller function

DFR1 provides pressure and flow control with the X-to-tank connection closed in the reviewed Series 31 design. Confirm the pilot-line unloading arrangement against the applicable hydraulic diagram.

How to check the fit

Check the actual sealing specification and fluid alongside the mechanical dimensions. Similar PPA and VPA text in listings does not establish interchangeability.
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.
