The Wacker Neuson Tank with Pump is a genuine OEM assembly designed for the RD40-130 and RD45-140 series tandem rollers, covering standard, C, O, US, DPF, and.3 variants across all corresponding machine configurations. As a direct OEM replacement, this assembly is built to the same specifications as the original unit, ensuring a consistent, trouble-free installation without guesswork. Wacker Neuson's genuine parts program backs this component with the quality assurance expected on professional-grade compaction equipment. Whether you're servicing a standard RD40-130 or a DPF-equipped RD45-140c, part number is the correct replacement to restore full system function.
Key Features
- OEM-Grade Fluid Containment and Pump Integrity — Built to original tank wall thickness and pump flow tolerances, ensuring no seepage, pressure drop, or output inconsistency after installation.
- Integrated Assembly for Direct Swap — Tank and pump are supplied as a matched unit, connecting to existing fittings and mounting points exactly as the original — no adapters or fabrication needed.
- Broad RD-Series Fitment — Confirmed compatible with RD40-130 and RD45-140 tandem rollers across standard, C, O, US, DPF, and .3 variant designations, covering a wide production range.
- Sustained Water System Performance — A properly functioning tank and pump assembly maintains consistent drum wetting on asphalt and granular surfaces, preventing material pickup and protecting compaction quality.
- Fuel and Fluid System Safety — Genuine OEM construction ensures the tank meets original pressure and containment ratings, reducing the risk of fluid leaks near hot or rotating machine components.
The tank with pump assembly on Wacker Neuson tandem rollers forms the heart of the drum wetting system, storing water and delivering it to the spray bars that keep the drums lubricated during compaction passes. Without consistent pump output and a leak-free tank, drums can stick to fresh asphalt, leaving marks or disrupting the mat surface. When this assembly wears out or develops a leak, spray coverage becomes uneven or stops entirely — making prompt replacement essential to maintaining compaction quality and protecting the finished surface.
