Sims Pump Valve Company Inc., of Hoboken, N.J., exclusively offers a patented structural composite material called Simsite. It’s a graphite combination-fiber, continuously interwoven, reinforced composite with phenolic/epoxy thermoset resin. Its continuous fibers provide the highest strength and flexibility available on the market today. The composites stand up better to corrosive environments, erosion and cavitation than metallics or other non-structural composites and will improve pump performance.
