Abstract:

The present invention utilizes high magnetic flux materials to substantially increase the power which can be transmitted from a magnetic driver, disposed outside of a vessel containing a fluid being processed, to a magnetically responsive agitator means disposed inside the vessel. This invention now enables the agitation, e. g. , mixing, blending, etc. , of fluids processed in the pharmaceutical, chemical and food processing industries, where relatively high torques are encountered, by non-contaminating magnetic drive means heretofore precluded in such applications. Means for producing vibrational agitation, and for reducing wear of the internal agitator bearing are also disclosed.
