The pump units operating with high head and large power in Ganhe pump station is independently researched, designed and manufactured by Chinese ourselves. This paper shows the research results, structural design and coating against sand abrasion of the pump units in Ganhe pump station. The successful exploitation of large-scale pump units with medium-low specific speed symbolizes that Chinese research on large-scale centrifugal pump units achieves the highest level in the world, and has improved significance to the technologies in the pump industry of China.Key words: Large-scale; single-suction single-stage centrifugal pump; medium-low specific speed; scientific research; design; coating against sand abrasion; water supply project; Yunnan province工程，是滇中调水的近期重点工程，近期重点向滇池补充生态水量，改善滇池水环境，并在昆明发生供水0前言牛栏江—滇池补水工程是一项水资源综合利用危机时，提供城市生活及工业用水。牛栏江—滇池补水工程由德泽水库水源枢纽工程、干河泵站工程及干 河泵站至昆明（盘龙江）的输水线路工程组成，其中，干河泵站为补水工程的核心，
