The Wacker Neuson Pump Injection EPA2 is a genuine OEM component designed for the DPS1850H, DPU2540H, DPU2550H, DPU2560H, and PT2H series machines. As a factory-sourced part, it meets the exact specifications required by Wacker Neuson for correct fuel delivery and emissions compliance on EPA Tier 2 engines. Compatibility extends across the full DPS1850H lineup — including Basic, Asphalt, and Vario configurations — as well as the DPU2560H-TS vibratory plate. Keeping the correct injection pump in service ensures your equipment runs cleanly, efficiently, and within regulatory standards.
Key Features
- OEM-Calibrated Fuel Delivery: — Manufactured to Wacker Neuson's exact injection timing and flow specifications, ensuring the engine receives the correct fuel charge for rated power output.
- EPA Tier 2 Emissions Compliance: — Engineered specifically for EPA2-rated engines; using the correct injection pump keeps your machine operating within required emissions limits.
- Direct-Mount Replacement: — Matches the original mounting configuration and fuel line connections, allowing straightforward removal and installation without modification to surrounding components.
- Broad Model Coverage: — A single part number covers the DPS1850H series, DPU2540H, DPU2550H, DPU2560H, DPU2560H-TS, and PT2H pump models, making it a versatile service stock item.
- Sustained Engine Performance: — A worn or degraded injection pump causes hard starting, loss of power, and erratic engine behavior; replacing it with 5000209686 restores consistent combustion and smooth operation.
The injection pump is responsible for delivering a precise, pressurized charge of fuel into the engine's combustion chamber at exactly the right moment in the engine cycle. It is a critical component of the diesel fuel system — when it wears or fails, the engine loses the consistent fuel supply it needs, resulting in misfires, reduced power, excessive smoke, or failure to start. On EPA2-rated engines in particular, correct injection pump function is also essential for maintaining the calibrated air-fuel ratio that keeps exhaust emissions within compliance thresholds.
