This is an Exhaust Fluid Pump designed to supply Diesel Exhaust Fluid (DEF) to the exhaust system for emissions control. It ensures proper atomization and injection of DEF into the exhaust stream to reduce NOx emissions, meeting stringent environmental standards. A failing pump may cause intermittent or constant check engine lights, reduced engine power, and increased exhaust emissions.
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 first sign of a failing exhaust fluid pump is often a check engine light or a DEF system warning on the operator display. If ignored, the pump may begin to intermittently fail, leading to reduced engine power and increased emissions. Continued operation with a faulty pump can result in the engine entering a reduced power mode or refusing to start.
Ensure the DEF tank is clean and free of any debris before installation to prevent immediate contamination of the new pump. Do not overtighten the pump mounting bolts, as this can damage the housing or mounting surface.
When replacing the exhaust fluid pump, it is recommended to inspect the DEF lines for any blockages or leaks and to check the DEF injector for proper operation.
