The disclosure provides a gear pump rotor assembly that includes a rotor body, a rotor head having a plurality of gear teeth and being connected to the rotor body, at least one connector extending between the rotor body and the rotor head, at least one radial deformation control member that extends into at least one gear tooth of the rotor head and reduces the radial deformation of the rotor head relative to the rotor body when a change in temperature causes radial deformation of the rotor body and rotor head.

Rotor assemblies having radial deformation control members

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.
