The Wacker Neuson Water Pump is a genuine OEM Water Pump designed for the RD18-80, RD18-100, and RD18-100c series double drum rollers, including their.3-generation variants. As a factory-sourced component, it is manufactured to the exact specifications required by Wacker Neuson for these machines, ensuring a direct, hassle-free installation. This pump is confirmed to fit the RD18-80, RD18-80.3, RD18-100, RD18-100.3, RD18-100c, and RD18-100c.3 models, making it the dependable choice when you need a like-for-like replacement you can trust.
Key Features
- OEM Flow and Pressure Ratings — Manufactured to Wacker Neuson's exact output specifications, so the pump delivers the correct water volume and pressure the drum sprinkling system depends on.
- Drop-In Replacement — Matches the original mounting points, port sizing, and inlet/outlet orientation for a straightforward swap with no adaptation needed.
- Broad RD18 Series Coverage — Fits all six variants across the RD18-80 and RD18-100 families, including first-generation and .3-generation machines.
- Sustained Drum Wetting Performance — A fully functioning water pump keeps drums properly wetted during compaction, preventing asphalt pickup and maintaining surface quality on every pass.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, so the materials and construction meet the same standard as the pump installed at the factory.
The water pump on a double drum roller circulates water to the drum sprinkling system, keeping the compaction surfaces continuously wetted during asphalt and soil work. This prevents hot mix from sticking to the drums and ensures a clean, consistent pass across the mat. When the pump begins to fail — whether through seal wear, impeller damage, or loss of pressure — drum wetting becomes uneven or stops entirely, which can cause material pickup, surface tearing, and a significant drop in compaction quality. Replacing a worn pump promptly with the correct OEM part restores full sprinkling function and protects both the work surface and the drums themselves.
