ABSTRACT:
A rotary pump with an inlet flow duct having a convergent section upstream the tips of the rotor blades. The convergent section decreases the cross-sectional flow area of the inlet flow duct prior to the flow being introduced into the rotor, thereby creating a substantially uniform velocity profile in the flow just upstream the rotor blades.
