The Wacker Neuson Injection Pump is a genuine OEM component designed for the PT2H centrifugal trash pump series, DPU 2440H through DPU 2560H reversible vibratory plate compactors, and DPS 1850H single-direction vibratory plate compactors. As a factory-sourced part, the meets the exact tolerances and fuel delivery specifications required by these diesel-powered machines. This pump is confirmed to fit multiple configurations across the DPS 1850H family — including Basic, Asphalt, and Vario variants — as well as the DPU 2560H-TS. Keeping the correct injection pump in service ensures clean, timed fuel delivery and consistent engine output across all compatible models.
Key Features
- Exact Fuel Delivery Specification — Genuine OEM sourcing means this injection pump matches the precise delivery pressure and timing calibration required by Wacker Neuson diesel engines in these equipment families.
- Direct-Fit Installation — Engineered to the same mounting interface and port configuration as the original, allowing straightforward removal and reinstallation without modification to fuel lines or mounting brackets.
- Broad Model Coverage — Fits the PT2H trash pump series, DPU 2440H, 2450H, 2540H, 2550H, 2560H, and 2560H-TS reversible plate compactors, plus DPS 1850H Basic, Asphalt, and Vario single-direction plates.
- Consistent Engine Power Output — A correctly functioning injection pump maintains the fuel pressure and timing that these diesel engines depend on for rated compaction force and pump performance. A worn or failing pump causes hard starts, rough running, and loss of working output.
- Fuel System Integrity — Using the correct OEM-spec injection pump on diesel compaction and pump equipment is critical to preventing unmetered fuel delivery, which can damage injectors and affect exhaust emissions compliance.
The injection pump is the heart of a diesel fuel system — it pressurizes and delivers precisely metered fuel to the injectors at the exact moment the engine requires it. On vibratory plate compactors and trash pumps like these Wacker Neuson models, consistent fuel delivery directly controls engine speed stability, compaction force, and pumping capacity. When an injection pump wears or fails, symptoms typically include difficult starting, uneven idling, loss of power under load, and excessive smoke — all of which point to incorrect fuel pressure or timing. Replacing the pump with a genuine OEM unit restores the fuel system to its original operating condition.
