self-lubricating qualities of the Sim- site material. Simsite can be lubricat- ed with water, saltwater, river water, oil, grease and even some chemicals. Cavitation resistance: Utilizing Simsite, through the re- design of impellers and pumps, pro- duces a substantially more cavitation resistant pump. Lightweight: Simsite is signiÞ cantly lighter than metallic materials; one-sixth the weight of bronze and stainless steel; and one- third the weight of titanium. The light- er mass means a substantial reduction in start-up load and increased energy savings, shaft movement and shaft de- ß ection, resulting in a much longer life for the bearings, mechanical seals, cas-ing, wear rings and sleeves. Corrosion resistance: The graphite used in Simsite is non- conductive, which means that Simsite will not support electrolysis or gal- vanic corrosion. It also means that the more Simsite used in the pump, the longer the pump will last. The U.S. Navy itself has described Sims pumps as, ÒThe only pump that is impervi- ous to saltwater corrosion.Ó Approvals: Simsite rings, wear rings, bearings, sleeves and bushings ap- proved by the United States Navy for surface Ships since 1994, the German Navy since 1998. Additionally, Sims enjoys approvals from ABS, Lloyds, DNV and Germanischer Lloyd. New Orleans(504) 780-8100 ? Fax (504) 780-8200Norfolk(757) 545-0100 ? Fax (757) 545-8004Houston(281) 452-5887 ?
