Theory of Operation
Multiple stages — each with a 316L impeller in a Duplex SS stage housing inside a Super Duplex shell — build pressure incrementally. The Water Bearing™ thrust system uses pumped product water as a hydrostatic film, keeping the shaft in tension and eliminating oil / grease maintenance. Each MSS pump is built to the specific duty point requested.
