Abstract The develop process for the two types 1XPB 2 and 1XPB 3 miniture shielded pump is introduced. The hydraulic models designed by velocity coefficients and similarity method are successful. Due to the small flow, low specific speed and high cavity requirement, the paper selects larger impeller inlet diameter D 0 and vane inlet width b 1 and suitable inlet vane angle β 1, and the tests show that the pump characteristics meet the design requirements.
