ABSTRACT:
Embodiments of the invention provide a compact, seal-less, centrifugal liquid pump with a perimeter magnetic drive that is substantially smaller than a conventional centrifugal liquid pump having magnets attached directly to the impeller shaft. Because rotational force is applied at the perimeter of the impeller, rather than at the shaft, embodiments of the invention have lower torque requirements and rotational speed, increasing the life of the pump bearings. Additionally, embodiments of the invention may suspend the pump bearings by using a redirected flow of liquid coolant, further increasing the bearing life.
