The Wacker Neuson Injection Pump Complete is a genuine OEM component designed for the DPU45Yeh US and DPU40Yeh US reversible plate compactors. Sourced directly from Wacker Neuson, this injection pump complete matches the original unit in every dimension, connection point, and output specification — ensuring it installs and performs exactly as the machine was engineered to run. Confirmed fitment covers the DPU45Yeh US () and DPU40Yeh US () models, so you can order with confidence knowing this is the correct part for your machine.
Key Features
- OEM-Calibrated Fuel Delivery — Manufactured to Wacker Neuson's original flow-rate and pressure specifications, ensuring the engine receives precisely metered fuel for consistent combustion and power output.
- Direct-Mount Replacement — Mounts to the existing fuel system interfaces on your compactor with no rework to lines, brackets, or fittings required.
- Verified Fitment for DPU Series Compactors — Confirmed fit for the DPU45Yeh US and DPU40Yeh US reversible plate compactors, covering both listed machine configurations.
- Protects Engine Performance Under Load — A correctly functioning injection pump complete maintains stable fuel pressure at high compaction demand; a worn or failing pump causes hard starts, rough running, and loss of compaction force.
- Fuel System Safety Compliance — As a genuine OEM fuel system assembly, this part meets the original sealing and pressure-containment standards designed into the machine — important for safe diesel operation on active worksites.
The injection pump complete is the heart of the diesel fuel system on a plate compactor. It draws fuel from the tank and delivers it at the correct pressure and volume to the injector, enabling the engine to fire reliably and maintain consistent power through each compaction pass. When the injection pump wears or fails, the engine may struggle to start, run unevenly, or stall under load — directly impacting compaction output and site productivity. Replacing a failing unit promptly with the correct OEM assembly restores proper fuel delivery and keeps the engine running within its designed operating parameters.
