The Wacker Neuson is a genuine OEM Injection Pump designed for DPU 4045H and DPU 5045H series reversible vibratory plate compactors. As a direct OEM replacement sourced through authorized Wacker Neuson supply channels, this part matches the original specification installed at the factory — ensuring correct fuel delivery calibration for the diesel engine powering these heavy-duty reversible plates. Verified fitment covers multiple machine configurations across the DPU 4045H and DPU 5045H families, making the right call when your diesel DPU is due for an injection pump replacement.
Key Features
- Calibrated Fuel Delivery: — Matched to the diesel engine's injection timing and pressure requirements on DPU 4045H and DPU 5045H compactors, maintaining consistent power output under load.
- Genuine OEM Component: — Sourced directly from Wacker Neuson, this injection pump meets the exact design tolerances of the original part — no guesswork on flow rate or fitment.
- Broad DPU Series Compatibility: — Confirmed fitment across numerous DPU 4045H and DPU 5045H machine configurations, including standard, ap, and eap variants in the 50 kN, 45 cm/18 in reversible plate range.
- Drop-In Diesel System Replacement: — Connects directly to the existing fuel system and mounting points on compatible DPU models — no adaptation or machining needed for installation.
- Protects Engine Integrity: — A failing injection pump causes erratic engine performance, hard starting, and loss of compaction force. Replacing with the correct OEM pump restores stable fuel atomization and prevents accelerated engine wear.
- Fuel System Safety: — Diesel injection pumps operate under high pressure; using an OEM-spec component ensures correct sealing and pressure containment, reducing the risk of fuel leaks during operation.
The injection pump is the heart of the diesel fuel system — it pressurizes and meters fuel, then delivers it to the injectors at precisely the right moment for combustion. On DPU series reversible vibratory plate compactors, a correctly functioning injection pump is essential for maintaining the engine power needed to drive the exciter mechanism and generate the compaction force these machines are built to deliver. When the injection pump wears or fails, symptoms typically include difficulty starting, rough running, loss of power, and excessive smoke — all of which directly compromise compaction performance and can lead to deeper engine damage if left unaddressed.
