DUAL CONTAINMENT SHELL
PFA lining with carbon fiber reinforced plastic (CFRP) shell. Non-metallic construction provides efficiencies the same or better than sealed ANSI pumps; 30% higher efficiencies than metal sealless pumps. Non-metallic construction eliminates magnet losses or heat generation. CFRP shell provides rigid support for the liner and acts as a secondary method of containment should the primary liner fail.

NON-SPARKING RUB RING
Assures containment shell integrity in the unlikely event of a ball bearing failure. Provides safe support of drive magnet in the clamp ring during assembly and disassembly.
