Improve Reliability and Efficiency of your Horizontal Pumps with Graphalloy [Case Study]

GRAPHALLOY, a graphite-metal alloy manufactured only by Graphite Metallizing Corporation, has long been used to provide reliability when pumping low-specific-gravity fluids or when “run dry” conditions occur. Successful applications include heater drain and condensate hotwell services in electric generating power stations, stripper pumps on barges, and light hydrocarbons pumps at hot, ambient, and cryogenic temperatures in petrochemical plants and refineries.

Because of these uses in vertical pumps, Graphite Metallizing Corporation next began working with pump manufacturers and repair facilities to apply our GRAPHALLOY experience to horizontal pumps.

The first horizontal applications were field conversions of pumps with histories of frequent breakdown. Often these were handling low-specific-gravity liquids. In a standard pump design with metal wear rings and metal stationary parts, poor lubrication or transient run-dry conditions cause the pump to gall or seize. GRAPHALLOY stationary wear rings improved reliability, lowered vibration, and provided higher efficiency. Since 1979 horizontal pumps of many manufactures have been upgraded with GRAPHALLOY wear parts in applications from pipelines to boiler feed services. Each has enhanced GRAPHALLOY’s reputation as the effective solution to a trouble-prone pump.

How much can GRAPHALLOY improve pump operation?
