A descaler is a device that is used to remove scales from heat treated steel at hot rolling mills. Scales are impurities that affect the appearance and properties of heat treated steel. Oxide scales form on heat treated steel when the iron in the steel is exposed to the oxygen in the air during the heat treating process. This study focuses on the performance improvement and miniaturization of a high pressure multistage centrifugal pump model which is used for descaling in a hot rolling mill. In order to achieve the performance improvement and miniaturization of this multistage pump, the flow passage shapes including impeller, diffuser and return vane have been newly designed. The design process of new flow passage shapes were discussed in detail. A commercial numerical code (ANSYS CFX) was adopted to conduct the numerical simulation for pump models and only two stages of the pump models were analysed to reduce solving time. The internal flow characteristics were compared with original and new design. The new designed flow passage shapes of multistage pump model were smaller and the new design showed a better efficiency and much smoother internal flow characteristics, which means that the performance improvement and miniaturization of the multistage pump model were achieved.
