CENTRIFUGAL IMPELLER/PROPELLER PUMP SYSTEM

摘要

A housing (14) includes a major component (16) with a planar section (18). The planar section has an aperture (20) constituting an inlet. The major component has a generally cylindrical peripheral section (26) formed with a tangential extension (32) constituting an outlet. The housing also includes a minor component (38) with a planar section (40). The planar section has an aperture (42) constituting an outlet. A tangential extension (48) is adapted to overlie the major component for creating a chamber. A rotatable assembly (56) includes an annular plate (58) with an aperture (60), spaced impeller segments (64), and a propeller with an axial bore (66) and propeller blades (68) with openings between the blades. The bore is adapted to receive a drive shaft of a motor for rotating the propeller and the annular plate and the impeller segments.
