Multiquip 8982264734 DEF Pump Assembly DCM Supply - OEM Replacement Part

This DEF (Diesel Exhaust Fluid) pump assembly provides precise delivery of diesel exhaust fluid to the selective catalytic reduction (SCR) system in Multiquip super silent generators. The DCM supply pump is a critical emissions control component that meters and injects DEF into the exhaust stream to reduce NOx emissions and maintain EPA Tier 4 Final compliance. Failure of this pump assembly can result in derated engine performance, emission system faults, or complete shutdown depending on the generator's emission control strategy.

Designed for demanding commercial and industrial applications, this pump assembly integrates directly with the generator's engine control module to ensure proper DEF dosing across all load conditions. Regular inspection of DEF pump operation is recommended as part of scheduled maintenance intervals to prevent unexpected downtime and maintain optimal emission system performance.
