Abstract
A magnetically engaged pump includes a pump housing with a rotatable magnetic drive assembly, a cylindrical canister and a rotatable driven magnet assembly. This magnetic coupling is associated with a pump rotor and a laterally positioned gear wheel to define a gear pump. This magnetic coupling is alternatively associated with a pump rotor with an impeller to define a centrifugal pump. Either pump includes a stationary shaft to mount the driven magnet assembly and pump rotor. A rotatable carrier with bushings and thrust bushings coaxially supports the rotatable driven magnet assembly and pump rotor.
