The pump operates by drawing the AdBlue fluid from the tank, pressurizing it, and precisely metering the fluid into the exhaust stream. It is regulated by the engine control unit (ECU), which constantly monitors exhaust gas temperature and NOx levels to ensure optimal dosing.

This BFO WK5Z47 Def Fluid Doser Pump is a direct replacement for the original equipment manufactured (OEM) part. It is designed to fit seamlessly into the existing system, ensuring a perfect fit and reliable operation.
