Emitec urea pumps are specialized AdBlue/DEF (Diesel Exhaust Fluid) dosing units used in heavy-duty commercial diesel vehicles to reduce harmful nitrogen oxide emissions.
Key Functions and Features
· Precise Dosing: Delivers exact amounts of urea into the exhaust stream to ensure proper Selective Catalytic Reduction (SCR) reactions.
· Air-Assist Integration: Uses vehicle compressed air to mix, atomize, and inject the fluid cleanly into the exhaust pipe.
· Built-In Heating: Features internal heating devices to prevent fluid freezing and protect components in cold weather down below -11° C.
· Smart Diagnostics: Communicates directly with the engine control unit (ECM) via a J1939 CAN link to report self-diagnostic statuses and error codes.
Common Applications
· Widely utilized in commercial trucks and heavy-duty machinery featuring Cummins and DAF engines (such as common replacement part numbers like 5273338 and 5273337)
