Fail-Safe Pump Technology Wins Vaaler Award
Description
This episode of Distilled features the final 2025 Vaaler Award winner: Flowserve's INNOMAG TB-MAG Dual Drive. This sealless pump technology provides secondary containment through the pump itself rather than the motor, unlike canned motor pumps. The system prevents catastrophic leaks of toxic and corrosive fluids while handling up to 30% solids. Nick Rentzelos, the technology's inventor and Flowserve's director, explains how the maintenance-free design addresses the skilled workforce shortage and stringent safety regulations. The pump features hydrodynamic silicon carbide bearings that don't wear, requires no seal replacement or shaft alignment, and easily retrofits into existing facilities. Energy-efficient carbon fiber containment shells replace traditional metal cans, reducing friction and motor drag while keeping hazardous fluids completely isolated from electrical components.
