A system for pumping or mixing a fluid using a levitating, rotating pumping or mixing element and various other components for use in a pumping or mixing system as disclosed. The pumping or mixing element is placed in a fluid-containing vessel in close proximity to a superconducting element. A cooling source thermally linked to the superconducting element provides the necessary cooking to induce levitation in the pumping or mixing element. The superconducting element may be thermally isolated, such that the pumping or mixing element, the vessel, and any fluid contained therein are not exposed to the cold temperatures required to produce the desired superconductive effects and the resulting levitation. By using means external to the vessel to rotate and/or stabilize the pumping or mixing element levitating in the fluid, including possibly rotating the superconducting element itself or moving it relative to the vessel, the desired effective pumping or mixing action may be provided.
