Abstract
The paper analysed geometry of eight profiles of flow duct, and established a mathematic model of geometry demensions of profiles of flow duct in spiral casing of centrifugal pumps. The hydraulic model of spiral casing of pumps with good performance was designed by CAD. It will improve pump efficiency and provide theoretical basis for designing eight profiles of flow duct in spiral casing of pump.
