Abstract
Rotodynamic pumps having an inner drive electro-magnet coupling disposed inside an impeller are disclosed. 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 an electro-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 a stationary component having multiple electro-magnets that are disposed inside of and are in axial alignment with the outer magnets. A canister is sealed to the casing and separates the outer magnets from the multiple electro-magnets.
Claims23
A rotodynamic pump having an inner drive electro-magnet coupling disposed inside of an impeller comprising:
- a pump casing defining a pumping cavity;
- an inlet port connected to the pumping cavity;
- a discharge port connected to the pumping cavity;
- an impeller being rotatable about a rotational axis and disposed within the pumping cavity,
- the impeller having a pumping region generally in a pumping plane that is perpendicular to the rotational axis and aligned with an electro-magnet coupling that includes outer magnets that are connected to the impeller and at least partially axially aligned with the pumping region of the impeller,
- a stationary component having multiple electro-magnets that are disposed inside of and are in axial alignment with the outer magnets, and
- a canister that is sealed to the casing and separates the outer magnets from the multiple electro-magnets.
