An experimental study has been performed on energy characteristics of axial-flow pumps designed for one pumping station in Jiangsu province, China. The energy characteristic tests for two different model runners were carried out. The result shows that the airfoil shape of the blade profile has significant effect on the performances of the pumps. Efficiency of the pumps can be improved by using smaller camber and larger blade density.
