There are three pumping stations in the first stage of Eastern Route S-to-N Water Diversion Project in China, where the mixed-flow pumps with guide vanes are installed, consisting of Baoying, Hongze and the No. 2 Suining pumping stations. By using flow rate coefficient and head coefficient as expression, firstly the hydraulic performances of the hydro models used are analyzed. Secondly the structural features and system performances are compared. And finally the measurement results in site are comprehensively evaluated. The results show that the pump models both introduced abroad and developed at home and the pumping system types adopted in the three pumping stations have been confirmed satisfying the requirements of operational conditions and high efficiency, stable and safety operation in all working conditions can be ensured.
