REXROTH A10VO28 DFLR/3x SEAL KIT

The Rexroth A10VO28 DFLR/3X Seal Kit is a genuine sealing set built for the rebuild and overhaul of Rexroth’s A10VO28 open-circuit variable displacement axial piston pump fitted with the DFLR pressure, flow, and power control valve. It includes the shaft seal, O-rings, and gaskets needed to properly reseal the pump housing, rotary group, and control valve assembly during service — restoring the pump’s sealing performance without the expense of a full unit replacement.

The A10VO28 is a 28cc swashplate-design pump built for open-circuit mobile hydraulics, with a permissible working pressure of 280 bar and speeds reaching up to 3600 rpm. The DFLR control variant adds combined pressure, flow, and power regulation, allowing the swivel angle and output flow to adjust automatically so the product of flow and pressure stays constant — a feature commonly used in construction, agricultural, and industrial machinery where engine power needs to be matched precisely to hydraulic demand. Because this control function relies on tight internal sealing to respond accurately, worn seals here often show up as sluggish control response, inconsistent flow output, or case leakage well before the rest of the pump shows signs of wear.

Rebuilding with a genuine Rexroth seal kit rather than a generic equivalent keeps every seal matched to the exact material and dimensional tolerances the A10VO28 DFLR was engineered around. This is particularly important given how the DFLR control valve depends on precise sealing to regulate flow and pressure correctly. Reseal work done with the correct kit during scheduled maintenance helps prevent leaks, protects the rotary group from contamination, and keeps the pump’s control response performing as designed.
