For free information on the Saab Tank Control division products as well as the TankRadar system, Circle 8 0 on Reader Service Card SIMS Sims Pump Valve Company, Hoboken, NJ developed and manufactures Simsite® impellers, casing rings, and other components for marine and stationary centrifugal pumps. Sims was established in 1919 with the invention of the Sims pump valve for use in reciprocating pumps.

Recognizing that conventional metal impellers became porous when used in service such as salt water, Sims in 1955 introduced the casing ring made of Simsite. The innovative use of this composite material, a combination of reinforced resin and graphite, met with great success. It outlasted by far the life expectancy of bronze. Six years later the Simsite impeller joined the already proven casing ring.

Of Simsite's many advantages over metal, one is its resistance to corrosion in salt water and various chemical applications. As a replacement replacement for worn original equipment and as a specification for new, the material's great strength and light weight make handling easy, and wear on pump parts is reduced greatly by the natural lubricating action of its graphite content.
