DEF Doser Pump Cummins 5418889 | 4353810, A060H209, 5303916, 5375478

High-Performance DEF Doser Pump for Cummins Engines

The Cummins 5418889 DEF Doser Pump is a critical component engineered for heavy-duty trucks to maintain peak efficiency in the emissions control system. By precisely injecting Diesel Exhaust Fluid (DEF) into the exhaust stream upstream of the Selective Catalytic Reduction (SCR) catalyst, this pump plays a vital role in reducing harmful nitrogen oxide (NOx) emissions. This part is also available under the numbers: 4353810, A060H209, 5303916, and 5375478.

Controlled directly by the engine’s Electronic Control Unit (ECU), the 5418889 doser pump monitors real-time parameters such as exhaust temperature and engine load to deliver the exact amount of DEF required. This precise dosing ensures compliance with environmental regulations, maximizes SCR system efficiency, and helps improve overall fuel economy while reducing long-term maintenance costs.
