Abstract
A pump includes a fluid inlet section, a fluid outlet section, a rotor axially between the fluid inlet section and the fluid outlet section, a center section radially inside of the rotor and a stator including electrical coils for generating electromagnetic flux for moving the rotor around the center section. The rotor and the center section define a fluid flow chamber radially therebetween. The rotor is rotatable about the center section by the electromagnetic flux generated by the electrical coils. An inlet control section is configured for regulating fluid flow from the fluid inlet section into the fluid flow chamber during rotation of the rotor inside of the stator about the center section. An outlet control section is configured for regulating fluid flow from the fluid flow chamber into the fluid outlet section during rotation of the rotor inside of the stator about the center section. The electrical coils are axially offset from the rotor.
