The Doser Pump with part number 5505779RX is an essential component of the selective catalytic reduction (SCR) system in modern diesel trucks. This pump is responsible for injecting a precise amount of diesel exhaust fluid (DEF) into the exhaust stream to reduce harmful emissions. The DEF is stored in a separate tank and the Doser Pump draws it in and injects it into the hot exhaust gases. The pump operates using compressed air, which pushes on a diaphragm to move the DEF through the injection nozzle. Proper maintenance and replacement of this pump is crucial for efficient operation of the SCR system and ensuring compliance with emissions regulations.
