Genuine Brand New Engine Parts SCR Adblue Urea Doser Pump 2722701

✅ High-Precision Dosing
Delivers accurate amounts of AdBlue/DEF based on real-time engine load, temperature, and NOx sensor data — ensuring optimal catalytic conversion efficiency.
✅ Reduces NOx Emissions by Up to 85%
Critical for meeting Euro 6 emission standards, which limit NOx output to ≤ 0.4 g/kWh.
✅ Integrated Design
Combines dosing pump, injector nozzle, heater elements, and electronic control in one compact module — simplifies installation and maintenance.
✅ Self-Cleaning Functionality
Many versions include automatic post-injection purge cycles to prevent crystallization in the nozzle during shutdown.
✅ Corrosion Resistant Materials
Constructed to withstand exposure to aqueous urea solution (AdBlue/DEF), moisture, road salt, and high under-vehicle temperatures.
