INTRODUCTION There are two factors that affect the overall efficiency of a pumping station: (1) system; (2) pump. System in fact a certain speed of the pump characteristic curve and the system characteristic curve must only intersect a little (Figure 1). When starting the pump, always select a pump to make it characteristic
