Sims Pump Valve Offers Durable Composite Impellers And Parts For Marine Use

Precision composite parts manufactured by the Sims Pumps Valve Co., Hoboken, N.J., have been successfully employed on seagoing vessels for nearly 30 years.

In 1955, Sims Pump Valve introduced a casing ring made of a composite material called Simsite. The highly innovative use of this composite material met with great success.

Six years later, the first Simsite impeller joined the already proven Simsite casing ring.

According to Sims, Simsite graphite impellers are hydraulically and mechanically superior to cast metal impellers. They are precision machined on both the outside and the inside of the impeller providing absolutely uniform vane characteristics and tolerances of .002 inches.

Fluid flow is, therefore, unaffected by casting imperfections, balance problems or rough surfaces.

The light weight of these impellers substantially reduces static deflection and radial forces in a pump helping to provide much longer rotating element life expectancy.

Sims claims that Simsite will not corrode in salt or brackish water.

Because of these inherent advantages, the balance, performance and efficiency of pumps with Simsite impellers remains constant. These impellers can be custom designed to solve such troublesome problems as recirculation cavitation or radial reaction.

Engineered composite pump components designed and manufactured by Sims since 1919, include wear rings, casing rings and bushings, all of which exhibit low wear, corrosion resistance and enhanced New Literature Offered performance in shipboard applications.

Simsite parts are used extensively in ships operated by such leading operators as Carnival Cruise Lines, Sea Land and Chevron. Because of its unusual durability, Simsite is also being considered for use in decorative and structural elements.

Sims Pump Valve Co. was also recently involved in the installation of Simsite impellers at Florida's Miami Seaquarium. The Sims venture into handling large volumes of seawater on land occurred when it responded to an emergency call by the Seaquarium by replacing worn out metal pump impellers that serve the attraction's whale holding tank with Simsite impellers. Installed only one week after they were ordered by the Seaquarium, the Simsite impellers perform flawlessly in the 1,200-gpm pumps that move five million gallons of seawater daily.
