This DEF Urea Pump is a key component of the Selective Catalytic Reduction (SCR) system, precisely injecting diesel exhaust fluid (DEF) into the exhaust stream to reduce NOx emissions. Manufactured to meet rigorous emissions control standards, it ensures accurate dosing compared to a worn pump with a clogged injector or faulty pressure regulator. Observable symptoms of a failing DEF pump include illuminated check engine or SCR system warning lights and increased exhaust emissions.

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 initial indication of a faulty DEF urea pump is typically the illumination of the check engine or SCR system warning light. This may be followed by a reduction in engine power or an inability to restart the engine if the system fault persists. Failure to address DEF system issues can lead to non-compliance with emissions regulations and potential operational restrictions.

Installation Tip

Ensure the DEF tank and lines are clean before installing the new pump to prevent contamination. Bleed the system properly after installation according to the manufacturer's service procedures.

Service Note

Inspect the DEF filter, injector, and tank level sensor during DEF urea pump replacement.
