This is a 24V DEF exhaust fluid pump, designed to accurately deliver Diesel Exhaust Fluid (DEF) into the exhaust system of Volvo trucks to reduce emissions. It operates under precise control to ensure the correct amount of DEF is injected, meeting stringent environmental regulations, and is built with materials resistant to DEF corrosion, unlike a failing pump that may leak or fail to deliver fluid. Operators might observe a DEF system warning light on the dashboard, reduced engine power (limp mode), or an exhaust system fault code when this pump malfunctions.
Always verify with serial number before ordering.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The most common initial symptom of a failing DEF pump is a dashboard warning light indicating a DEF system malfunction. This can progress to reduced engine power or 'limp mode' if the DEF level or injection is insufficient. Ultimately, a non-functional DEF pump will prevent the vehicle from operating correctly and may lead to failed emissions inspections.
Ensure the DEF tank is clean and free of any sediment before installing the new pump to prevent immediate contamination. Verify that all electrical connections are clean and securely fastened.
When replacing the DEF pump, it is crucial to inspect the DEF filter and lines for any blockages or signs of crystallization.
