The disclosure provides pumps that include improvements in construction, which involve bearing surfaces, recirculation paths, mounting footprints, impeller vane starting diameters, canister assemblies, and rotor assembly bushing configurations.

Pump devices

Rotary devices having a casing and an inner drive portion of a magnet coupling disposed inside of a rotor assembly are disclosed. The inner drive portion and rotor assembly are disposed within the casing and rotatable about a rotational axis. The rotor assembly includes a bushing between the magnets of the rotor assembly and a stationary canister is sealed to the casing and separates an internal fluid chamber within the casing from the inner driven portion. The stationary canister can be of multi-piece or unitary construction and is held in position by a front portion of the casing.

Rotary device having a radial magnetic coupling

Rotodynamic pumps having an inner drive permanent magnet coupling disposed inside an impeller are provided. The impeller has a casing having a pumping region generally in a pumping plane that is perpendicular to the rotational axis of the impeller and aligned with a permanent magnet coupling that includes outer magnets that are connected to the impeller and at least partially aligned with the pumping region of the impeller, and inner magnets that are connected to an inner magnet ring and are axially aligned with the outer magnets. A canister is sealed to the casing and separates the outer magnets from the inner magnets.
