Abstract：The achievements of unit test of pump models in pump stations of Wannian Xia, Jietai, Liushan, Taier Zhuang et al. were presented. The analysis results of them and their tests on single pumps show that, there are great difference between them, the blade angle on the best efficient point is larger by 2%-4%, and the efficiency of single pump is higher than that of pump unit by 8%-10%, and the water head of pump unit with the best efficiency approximately equal to those of single pumps, and with the scope of ?5%.These difference have not been grasped qualitatively, in this case, choosing pump according to the test results of pump units is better than that of single pump, which can improve the reliability.
