The Wacker Neuson Injection Pump EPA2 is a genuine OEM component designed for the PT2H pump series, DPS1850H series, and DPU2540H, DPU2550H, and DPU2560H plate compactors. As a direct Wacker Neuson OEM part, it is manufactured to the same standards as the original unit it replaces, ensuring a correct, confirmed fit across all listed models. This injection pump is rated for EPA Tier 2 emissions compliance, making it the appropriate replacement for machines built to that standard. Keeping this component in good working order is essential to consistent engine starting, smooth fuel delivery, and dependable output across demanding job applications.
Key Features
- EPA Tier 2 Compliant Fuel Delivery: — Rated specifically for EPA2-spec engines, ensuring correct fuel metering and emissions compliance for the machines it serves.
- Genuine OEM Construction: — Sourced directly from Wacker Neuson, this injection pump matches the original component's pressure rating, port geometry, and material grade — no guesswork on fitment.
- Broad Model Coverage: — Confirmed fit across PT2H trash pumps, DPS1850H Basic, Asphalt, and Vario variants, plus DPU2540H, DPU2550H, DPU2560H, and DPU2560H-TS plate compactors.
- Consistent Engine Performance: — A functioning injection pump delivers the precise fuel charge the engine needs at every cycle; a worn or failed pump leads to hard starts, rough running, and loss of power.
- Fuel System Integrity: — Correct injection timing and pressure prevent over-fueling and combustion irregularities that can damage downstream engine components over time.
- Direct OEM Part Number Reference: — Order with confidence using part number 5000209659 to verify an exact match before installation.
An injection pump is the heart of a diesel or gasoline direct-injection fuel system — it pressurizes and meters fuel, delivering precisely timed charges to the engine's combustion chamber. On compact equipment like plate compactors and trash pumps, this pump works continuously under load, and any drop in delivery pressure or timing accuracy will show up immediately as sluggish performance, difficult starting, or inconsistent throttle response. When the injection pump fails or wears beyond tolerance, the engine can no longer sustain the combustion cycle reliably, and continued operation risks damage to injectors and internal engine components.
