This DEF Urea Pump is a critical component of the Selective Catalytic Reduction (SCR) system, precisely dosing diesel exhaust fluid (DEF) into the exhaust stream to reduce harmful NOx emissions. Manufactured to meet stringent OEM quality specifications, it ensures accurate fluid delivery unlike a worn pump that can lead to incorrect dosing or system failure. Observable issues include illuminated SCR warning lights, reduced engine power (derate), and failed emissions tests.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The first indication of a faulty DEF urea pump is often an illuminated SCR system warning light on the dashboard. If the issue persists, the engine's performance may be reduced through a power derate to meet emissions standards. The ultimate consequence is the inability to pass emissions inspections and potential regulatory fines.

Installation Tip

Ensure the DEF tank is clean and free of any contamination before installing the new pump. Avoid introducing air into the system by following the correct priming procedure.

Service Note

Inspect the DEF filter and lines for any signs of clogging or leaks when replacing the DEF urea pump.
