• The absolute velocities and static pressures in a standard type vortex pump were measured with five-hole pitot tubes for clarifying the flow conditions in the pump. The results can be summarized as follows : The flow through the impeller increased with an increase in discharge and the rate of increase was high in the over-discharge range. The boundary radius of the impeller inlet and outlet regions and the peripheral component of the velocity at the inlet decreased as the discharge increased. Furthermore, a theoretical investigation was made to clarify the internal flow conditions. The flow pattern theoretically obtained consists of a through-flow and a circulation flow, showing good agreement with the measured results.
