Abstract

A pump includes a housing including a first portion thereof defining opposed parallel spaced apart internal and exterior generally planar surfaces. The pump also includes a first impeller rotatably secured to the housing and positioned within the housing. The pump also includes a first axial flux motor connected to the first impeller and at least partially positioned within the housing. The first axial flux motor includes a first motor rotor fixedly secured to the first impeller. The first motor rotor has a generally planar surface thereof positioned adjacent to and parallel to the internal generally planar surface of the first portion of the housing. The first axial flux motor includes a first motor stator fixedly secured to the housing. The first motor stator has a generally planar surface thereof positioned adjacent to and parallel to the external generally planar surface of the first portion of the housing.
