The Wacker Neuson Booster Pump is a genuine OEM Booster Pump designed for the RD27-100 and RD27-120 series hydrostatic vibratory and tandem rollers. Sourced directly from Wacker Neuson, this part matches the original component specification exactly, ensuring proper integration within the machine's hydraulic system. Compatible across a wide range of RD27 variants — including RD27 Pro Tandem, RD27 Roller Basic T4F, and RD27 Roller Pro T4F configurations — this is the correct part for both scheduled maintenance and unplanned repairs. Verify your model and serial number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Hydraulic Integrity — Built to the original pressure and flow specifications required by the RD27 hydrostatic drive system, ensuring correct charge pressure delivery throughout the hydraulic circuit.
- Direct-Fit Installation — Matches the original mounting configuration and port connections on RD27-100 and RD27-120 rollers, allowing straightforward swap-out without modification to hydraulic lines or brackets.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 variants across multiple build configurations, including Pro Tandem, Basic T4F, and Pro T4F roller models.
- Sustained Propulsion Performance — A properly functioning booster pump maintains hydraulic charge pressure in the closed-loop drive circuit; a failing unit can cause sluggish propulsion, erratic travel speed, or complete loss of drive.
- Verified Wacker Neuson Part Number — Part number 5200012664 is the manufacturer-assigned reference, eliminating guesswork when cross-referencing against service documentation or parts diagrams.
The booster pump — also referred to as a charge pump — is a critical supporting component in a hydrostatic drive system. Its role is to maintain a minimum charge pressure within the closed-loop hydraulic circuit, replenishing fluid lost through internal leakage and ensuring the main drive pump and motor remain properly primed at all times. Without adequate charge pressure, the hydrostatic transmission cannot develop full tractive effort, and the machine may exhibit loss of drive, overheating, or erratic speed control. On a vibratory roller like the RD27, where precise and consistent propulsion directly affects compaction quality, a worn or failed booster pump can compromise both productivity and compaction results.
