SITRAK C7H MC11 MC13 Urea Pump EVO WG9925561034 SCR System Parts

SINOTRUK SITRAK Truck SCR / Urea Injection System Parts C7H MC11 MC13 Urea Pump EVO WG9925561034

The SINOTRUK SITRAK WG9925561034 Urea Pump EVO is a core component of the SCR emission-control system used with compatible MAN MC11/MC13 diesel engines, responsible for moving automotive urea solution from the storage side of the system toward the SCR dosing circuit so that the engine's emissions-control system can perform the required urea injection process. Current parts references identify WG9925561034 as a SITRAK EVO urea pump and associate it with applications including SITRAK C7H, C9H and G7S as well as MC11/MC13 engine configurations. During normal operation, the pump works together with the urea tank, filter element, supply and return lines, pressure-control components, dosing unit, urea nozzle, and electronic control system. The condition of the urea itself is also important because contamination, crystallization or unsuitable fluid can restrict the filter or passages and affect pump performance. Symptoms such as SCR warning messages, abnormal urea pressure, insufficient urea delivery, pump noise, or an engine emission-system fault should therefore be diagnosed through the complete urea circuit rather than assuming the pump is always the source of the problem. The related WG9925561039 filter element is also listed separately for the SITRAK urea pump system, making filter condition an important inspection point when servicing this assembly. Before installing WG9925561034, buyers should verify the complete part number, engine model, truck configuration, pump connector, mounting arrangement, and SCR system specification to ensure that the replacement pump matches the original vehicle configuration.
