Abstract: The main parameters of axial flow pump model at Xietai Pump Station on the eastline of southtonorth watertransfer project are determined with the flow analysis method. This model was characterized by large flow, high efficiency, wide high efficiency range, and good vaporization．The flow at +4° was 0.415 m^３/s and the efficiency at -2° was 86.31 % at the optimum work state. It can be employed in Xietai pump station and other similarities.
