The pump electronically commutated wet rotor design results in only one moving part in the entire pump. A spherically suspended rotor/impeller rests on top of a ceramic ball & is driven magnetically, thereby eliminating the need for a shaft motor connection. The pump lasts longer, consumes less power & offers superior performance characteristics when compared to other pumps in its class.
