The Wacker Neuson Injection Pump is a genuine OEM component designed for the PT3H centrifugal trash pump series and the DPU 3050H, DPU 3060H, DPU 3060H-TS, and DPU 3070H reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this injection pump meets the exact specifications of the original part — ensuring correct fuel delivery to the diesel engine without calibration guesswork. Whether you're servicing a PT3H on a dewatering site or keeping a DPU 3060H running through heavy compaction cycles, part number is the correct replacement. Confirm your model number before ordering to ensure fitment.
Key Features
- Genuine OEM Fuel Delivery Accuracy — Built to Wacker Neuson's original injection timing and output specification, so the diesel engine receives the correct fuel charge at every cycle — no tuning or adjustment needed after installation.
- Direct-Fit Replacement — Engineered to match the original mounting configuration and fuel line connections on compatible PT3H and DPU series models, dropping in as a straight swap for the worn pump.
- Broad DPU Series Coverage — Fits the DPU 3050H, DPU 3060H, DPU 3060H-TS, and DPU 3070H reversible vibratory plate compactors, as well as the PT3H diesel trash pump series.
- Consistent Engine Starting and Power Output — A functioning injection pump delivers a precise, timed fuel charge that keeps the diesel engine starting cleanly and sustaining full power output under load. A worn or failed pump causes hard starting, rough running, and loss of compaction or pump performance.
- Fuel System Integrity — As a genuine OEM component, this pump is built to operate within the closed fuel system without risk of pressure variance or seal incompatibility that can lead to fuel leaks — a critical concern on diesel-powered equipment.
The injection pump is responsible for pressurizing diesel fuel and delivering it to the engine's injectors at precisely the right moment in the combustion cycle. On diesel-powered equipment like the DPU series vibratory plates and the PT3H trash pump, accurate fuel injection directly controls engine power, efficiency, and cold-start performance. When an injection pump wears or fails, symptoms typically include difficulty starting, loss of power under load, excessive smoke, or complete failure to run — all of which bring compaction or pumping operations to a halt. Replacing the pump with a correct OEM unit restores the engine's designed performance without the risk of mismatched pressure specs or fitment issues.
