Pumping or mixing system using a levitating bearing

Other various component parts for using fluid for pump delivery or the system (10) system to mix and pump delivery, or a hybrid system using the magnetic bearing (14) which carries out surfacing rotation are offered. A magnetic bearing (14) is made to approach a superconducting element (20) densely, and is installed in a fluid receiving container. Cooling required in order to guide surfacing to a magnetic bearing is supplied by the separate source of cooling thermally linked to the superconducting element. A superconducting element (20) is thermally isolated so that it may not be exposed of the low temperature needed for the fluid accommodated a magnetic bearing, a container, and in it creating surfacing brought about by the desired superconductivity effect and it. Surfacing a magnetic bearing within fluid -- and -- it is rotation about the magnetic bearing -- and -- or by establishing the means prepared in the exterior of the container, in order to make it stabilize, Furthermore, desired efficient pump delivery or a mixed action is obtained by supposing that it is as optional selection, and rotating the superconducting element itself, or making it move relatively to a container.
