The authors carried out an investigation of the effects of the pump elements on the pump performance. The following conclusions are obtained ; (1) There are two types of head-capacity curves which depend on the fluid viscosity and they are classified by the vane angle and the dimension of flow channel. (2) The effect of clearance on the shut-off head is made clear with consideration of the vane angle, flow channel and fluid viscosity. (3) The shut-off head, maximum internal efficiency and torque dealt with in correlation to the dimensionless number based on vane angle, dimension of flow channel and fluid viscosity are systematically arranged. Also the shut-off head of radial vane type is ascertained with a widely changing number of vanes and sectional area of flow channel. (4) The head loss in the flow channel is determined taking into account the vane angle and the sectional area of flow channel.
