2655852 Urea Pump is a high-precision AdBlue (urea aqueous solution) metering and conveying device specially designed for the SCR post-treatment system of commercial vehicles. Its core function is to precisely spray the urea solution into the exhaust system, through which a chemical reaction reduces nitrogen oxide emissions, meeting the mainstream emission regulations such as Euro IV to Euro VI. As a key component for diesel engine emission control, its performance directly determines the vehicle's emission compliance and operational stability.
