The Wacker Neuson is a genuine OEM Water Pump Assembly designed for RD12 and RD16 series tandem vibratory rollers. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component fitted at the factory. Compatible models include the RD12-90, RD12A-90, RD16-90, and RD16-100 — covering both standard and hydrostatic configurations, as well as fixed and foldable ROPS variants. When the water pump on your roller fails, drum surface wetting stops, asphalt temperatures spike, and material pickup becomes a serious operational problem — making a fast, accurate replacement critical.
Key Features
- Genuine OEM Flow and Pressure Specs — Built to the exact output ratings of the original Wacker Neuson water pump, ensuring consistent drum wetting across full roller passes.
- Direct-Fit Installation — Matches the original mounting configuration and port connections on RD12 and RD16 series rollers, so the assembly drops in without modification to brackets or plumbing.
- Broad RD-Series Compatibility — Verified fitment across RD12-90, RD12A-90, RD16-90, and RD16-100 models, including hydrostatic drive and foldable ROPS variants.
- Protects Asphalt Surface Quality — A properly functioning water pump prevents hot mix from adhering to the drum, maintaining a clean contact surface and a consistent mat finish on every pass.
- Verified Wacker Neuson Part Number — Part number 5000164155 is confirmed against Wacker Neuson OEM documentation, so you can order with confidence that this is the correct replacement.
The water pump assembly on a tandem vibratory roller circulates water to the drum surface during asphalt compaction, creating a thin film that prevents hot mix from bonding to the steel drum. Without adequate drum wetting, material pickup occurs — leaving voids in the mat, damaging the surface finish, and forcing additional passes. A worn or failed water pump can also allow heat to build unevenly across the drum face, which compromises compaction consistency and increases the risk of surface defects. Replacing a failed assembly promptly with the correct OEM part restores full drum wetting function and keeps the roller performing to specification on every lift.
