The Wacker Neuson Injection Pump is a genuine OEM component designed for the DPU 5045H and DPU 4045H reversible vibratory plate compactors. As a direct Wacker Neuson OEM part, the is manufactured to the exact specification of the original, ensuring a correct installation with no guesswork on fitment. This injection pump is confirmed compatible with multiple DPU 5045H and DPU 4045H configurations, making it the straightforward choice when servicing these heavy-duty diesel reversible plates.
Key Features
- Genuine OEM Fuel Delivery Spec — Manufactured by Wacker Neuson to the original injection timing and output spec, ensuring correct fuel delivery for the diesel engine powering these DPU plates.
- Direct Drop-In Replacement — Engineered to match the original mounting points and fuel line connections on the DPU 5045H and DPU 4045H, so installation follows standard service procedures.
- Broad DPU Series Fitment — Covers multiple build variants of the DPU 5045H and DPU 4045H reversible vibratory plates, including both standard and 750 series configurations.
- Sustained Compaction Output — A correctly functioning injection pump maintains consistent engine power delivery, which is critical to achieving the full 50 kN compaction force these machines are rated for.
- Fuel System Integrity — Using the correct OEM injection pump guards against improper fuel metering, which can cause hard starting, uneven engine performance, or premature wear on internal engine components.
The injection pump is the heart of the diesel fuel system, responsible for pressurizing and metering fuel from the tank to the engine's combustion chamber at precisely the right moment. On diesel-powered DPU reversible plate compactors like the DPU 5045H and DPU 4045H, the injection pump directly controls engine power output — meaning a worn or failing pump will cause loss of compaction force, rough running, or difficulty starting. Replacing a faulty injection pump with a genuine Wacker Neuson part restores correct fuel pressure and timing, bringing the machine back to full operating performance.
