The Wacker Neuson Water Pump Complete is a genuine OEM Water Pump Complete designed for RTLx-SC3 Trench Rollers, RTL82-SC3 Smooth Drum Rollers, DPU110 series plate compactors, and the HTC15 Trench Roller. As a factory-sourced assembly, this complete unit is produced to the same specifications as the original component installed at the time of manufacture. Verified against a wide range of RTLx-SC3 and DPU110 configurations — including EC, EM, and US-market variants — part number is the correct replacement when your cooling or water circulation system needs attention.
Key Features
- Genuine OEM Cooling Integrity — Manufactured by Wacker Neuson to the same flow rate, port sizing, and seal tolerances as the original pump, ensuring the cooling circuit performs exactly as designed.
- Complete Assembly, Ready to Install — Supplied as a fully assembled pump unit; all internal components are pre-fitted, so installation drops straight into the existing pump mount without sourcing separate sub-components.
- Broad Fitment Across RTLx-SC3 and DPU110 Families — Confirmed for RTLx-SC3 and RTL82-SC3 Trench Rollers, DPU110Lec, DPU110Lem, DPU110rLec, DPU110rLem, DPU110Lekc variants, RTx-SC2 EU Trench Rollers, and the HTC15 Trench Roller.
- Sustained Engine Temperature Control — A properly functioning water pump keeps coolant circulating through the engine at the correct rate; a failed or worn pump leads to overheating, unplanned shutdowns, and potential engine damage on the worksite.
- Cooling System Safety Compliance — Using a genuine OEM replacement maintains the integrity of the engine cooling system, which is critical to safe continuous operation under the high-load conditions typical of compaction and trenching work.
The water pump is the heart of the engine's liquid cooling system. It circulates coolant from the radiator through the engine block and back, drawing heat away from critical components and keeping operating temperatures within a safe range. When the pump wears out — through seal failure, impeller damage, or bearing degradation — coolant flow drops, engine temperature climbs, and the machine will eventually shut down to prevent serious internal damage. Replacing the pump as a complete assembly restores full cooling capacity and protects the engine from the strain of overheating.
