Key Features

  • Genuine OEM Cooling Circuit Integrity — Built to Wacker Neuson's original flow-rate and pressure specifications, so coolant circulation through the engine is exactly as the machine was engineered to deliver.
  • Drop-In Replacement — Matches the original mounting flange, port sizing, and connection points on RD18 series rollers for a straightforward swap using standard tooling.
  • Broad RD18 Series Coverage — Fits RD18-80, RD18-100, and RD18-100 C variants across multiple serial number ranges, including US and SE market machines.
  • Protects Engine from Overheating — A functioning water pump keeps coolant moving at the correct rate; a failing pump causes rapid temperature spikes that can lead to costly engine damage during compaction work.
  • Authorized OEM Part — Carries the full backing of Wacker Neuson's OEM parts program, giving you confidence in traceability, material quality, and long-term durability in demanding paving and compaction environments.

The water pump is responsible for circulating coolant through the engine's cooling system, drawing heat away from critical engine components and maintaining safe operating temperatures. On a tandem roller working long hours on hot asphalt, consistent coolant flow is essential — without it, engine temperature rises quickly and sustained operation becomes impossible. When a water pump begins to fail, common signs include coolant leaks around the pump housing, overheating warnings, and visible corrosion or bearing noise, all of which point to the need for prompt replacement to avoid deeper engine damage.
