Shangchai S00020626+03 Water Pump Assembly

The Shangchai S00020626+03 is a mechanical coolant water pump assembly designed for Shanghai Diesel (SDEC) D series heavy-duty diesel engines. It features a cast iron housing with precision-machined impeller and high-temperature ceramic-carbon mechanical seal to withstand extended thermal cycling. The unit integrates a sealed bearing assembly lubricated for service life, eliminating external lubrication points. This pump replaces OEM reference D20-000-900 and serves as direct fit for engine models including SC9D340D2 and 6DTAA8.9-G22. It is widely applied across heavy truck platforms such as Foton Auman, Sinotruk Howo, Hohan, Steyr, Shaanqi Delong, and Beiben vehicles equipped with Shangchai, Weichai WP6/WP7/WP13, or Sinotruk MC05/MC07/MC11/MC13 powerplants. Installation requires torque-to-spec fastening and coolant system pressure testing per manufacturer service manual.
