ABSTRACT:
An impeller forming a unit with the spherical rotor of a sphero-pump consists of a disc with vanes and an inlet member, both made by injection molding from resin. A rotor plate made from a thick gauge sheet metal covers the vanes and is held in position by rivet type protrusions on the inlet member and compensates the weight of the rotor.
