Abstract
A pump is provided. The pump includes a fluid inlet section; a fluid outlet section; a stator axially between the fluid inlet section and the fluid outlet section; a rotor axially between the fluid inlet section and the fluid outlet section, the rotor and the stator defining a fluid flow space radially therebetween; a movable inlet guide configured for guiding fluid flow from the fluid inlet section into the fluid flow space; and a movable outlet guide configured for guiding fluid flow from the fluid flow space into the fluid outlet section. The rotor is rotatable inside of the stator by electromagnetic forces urging the rotor towards the stator. Rotation of the rotor inside of the stator and movement of the inlet guide and the outlet guide create a pressure in a first portion of the fluid flow space that forces fluid from the fluid flow space through the fluid outlet section and create a vacuum in a second portion of the fluid flow space that pulls fluid from the fluid inlet section into the fluid flow space. A method of forming a pump is also provided.
