Abstract
A centrifugal pump of the pitot type is structured with axially-arranged inlet and discharge features positioned on opposing axial sides of a rotor, the rotor being journalled between a rotating sleeve and a suction inlet, and the rotating sleeve being concentric with the discharge, the rotating sleeve being gear-driven by a drive mechanism.
Claims21
A pump assembly, comprising:
- a rotating assembly having a rotor and a rotating sleeve;
- a stationary pitot tube assembly having at least one pitot tube positioned within said rotor;
- a fluid inlet positioned to deliver fluid to said rotor along a defined axis;
- and
- a fluid discharge axially arranged with the defined axis of said fluid inlet and being axially spaced from said fluid inlet,
- wherein said rotor is journalled between said rotating sleeve and said axially spaced fluid inlet.

A centrifugal pump, comprising;
- a pump housing having a rotor housing portion;
- a rotor disposed within said rotor housing portion, said rotor having axially opposed sides defined by a rotor bottom positioned on one side and a rotor cover positioned on the axially opposing side, said rotor bottom and rotor cover being secured together to form a closed chamber within said rotor;
- at least one pitot tube positioned within said closed chamber;
- a rotating sleeve connected to and extending away from one side of said rotor, said rotating sleeve being connected to a drive mechanism;
- a fluid inlet extending from one side of said rotor, said fluid inlet being positioned to deliver fluid to said rotor cover for directing fluid to said closed chamber;
- and
- a fluid discharge extending from said axially opposing side of said rotor,
- wherein said fluid inlet and said fluid discharge each have a central axis, and said central axes are axially arranged.
