Patent number US 9,771,938 B2 has been granted to PeopleFlo for a magnetically-coupled centrifugal pump design with a dual-purpose containment shell that also supports the impeller. By combining the functions of fluid containment and bushing support, the pump design is much simpler with fewer parts. Additionally, when the shell is made of silicon carbide, it’s highly wear-resistant, as well as non-conductive, so there are none of the typical eddy currents that waste energy and create unwanted heat.
