The Wacker Neuson Hydraulic Drive Pump is a genuine OEM component designed for the RD11A, RD11V, and RD11AEC hydrostatic double drum vibratory rollers. As a direct-source OEM part, it is manufactured to the same specifications as the original unit installed at the factory, ensuring a correct, verified fit within the machine's hydrostatic drive circuit. This pump is the authoritative replacement choice for contractors and equipment fleets running RD11 series tandem rollers who need a part they can trust to perform without compromise.
Key Features
- OEM Hydraulic Precision — Manufactured to original displacement and pressure tolerances, so the hydrostatic drive system delivers consistent power output from the moment of installation.
- Direct-Connect Replacement — Matches the original port configuration and mounting pattern of the RD11 series, integrating directly into the existing hydraulic circuit without alteration.
- RD11 Series Fitment — Verified for the RD11A, RD11V, and RD11AEC hydrostatic double drum vibratory rollers.
- Sustained Propulsion and Vibration Drive — A correctly functioning hydraulic drive pump keeps drum rotation, propulsion, and vibration circuits operating at rated capacity; a worn pump causes sluggish travel, loss of drum speed, and erratic compaction results.
- Hydraulic System Integrity — Using a correctly rated OEM pump prevents pressure imbalances that can stress seals, hoses, and downstream hydraulic components throughout the drivetrain.
The hydraulic drive pump is the heart of the RD11's hydrostatic transmission, converting engine power into pressurized hydraulic flow that drives both propulsion and drum vibration. When the pump is functioning correctly, the roller maintains precise travel speed and consistent vibratory force across the full compaction pass. As the pump wears, internal leakage reduces flow and pressure, leading to sluggish forward and reverse response, weakened drum vibration amplitude, and ultimately uneven compaction density — problems that become immediately apparent on asphalt and soil applications where pass consistency is critical.
