مجموعة مضخة معايرة اليوريا Albonair 1205710-K57P0

The 1205710-K57P0 is a urea dosing pump module designed for selective catalytic reduction (SCR) systems on heavy-duty commercial vehicles. It meters aqueous urea solution (AUS32/AdBlue) into the exhaust stream to reduce NOx emissions. The unit integrates a pump motor, pressure sensor, heating element (PTC), and dosing valve in a single housing. It operates on 24V vehicle electrical systems and communicates via CAN bus with the engine ECU. The pump is calibrated for Weichai and Dongfeng Cummins engine platforms meeting China V/VI emission standards. The aluminum housing ensures thermal dissipation and corrosion resistance. The bayonet-style electrical connector and quick-connect fluid fittings allow for service replacement without specialized tools. This part replaces Dongfing OEM numbers 1205710-K57P0 and 1205710-E9300.
