The Wacker Neuson Pump is a genuine OEM component designed for RD27-100 and RD27-120 series hydrostatic vibratory rollers, including standard and traction control configurations. As a direct factory replacement, this pump is sourced through Wacker Neuson's authorized parts supply chain, ensuring it meets the exact specifications of the original unit installed at the factory. Verified fitment spans multiple machine configurations across the RD27 series, making it a straightforward replacement for operators and service technicians working on these compact tandem rollers.
Key Features
- Genuine OEM Hydraulic Integrity — Sourced directly from Wacker Neuson, this pump is manufactured to match the original flow rate and pressure tolerances required by the RD27 hydrostatic drive system.
- Drop-In Replacement for RD27 Series — Engineered to connect directly to the existing hydraulic circuit on RD27-100 and RD27-120 rollers with no adaptation to fittings or mounting points.
- Broad RD27 Configuration Coverage — Compatible with standard hydrostatic vibratory roller builds and traction control variants across multiple machine numbers in the RD27-100 and RD27-120 families.
- Critical to Drive and Vibration Performance — A properly functioning pump sustains the hydraulic pressure needed for both propulsion and drum vibration; a worn or failing pump results in sluggish travel, loss of compaction force, or complete drive failure.
- Hydraulic System Safety — Correct pump specification prevents pressure surges or flow imbalances that can stress downstream hydraulic components, seals, and motors — making OEM spec essential in a closed-loop hydrostatic system.
The pump in the RD27 hydrostatic vibratory roller is a core element of the machine's closed-loop hydraulic system, responsible for generating and sustaining the fluid pressure that powers both the drive motors and the drum vibration circuit. Without adequate pump output, the roller loses the propulsion force and vibratory energy it needs to achieve proper compaction density on asphalt or soil. When this pump degrades — through internal wear, seal failure, or loss of displacement — operators will notice reduced travel speed, inconsistent vibration, or a complete loss of drive response, all of which signal that replacement is needed to restore the machine to full working capacity.
