Abstract: The design system is carried out on super-low-specific-speed high-speed centrifugal pumps. With head-capacity and efficiency-capacity display dynamically on computer screen, the design procedure which can be carried out automatically by computer and can shorten design, consists of the one-dimension optimum design with objective of efficiency and small flowrate stability, and three-dimension flow analysis on complex impeller. The experimental results and on-spot application of design example shows that the proposed method is reasonable.
