Abrasion-Resistant Pump Bushing Material


Graphlon GM 860®, developed by Graphite Metallizing Corp., is an abrasion-resistant bushing material that protects pumps and helps prolong pump life. This is a tough, polymer/graphite-based material used in the manufacture of pump bushings and other critical-wear parts. Graphlon GM 860 provides exceptional abrasion resistance in harsh environments. It has been developed specifically for sump pumps and river water service pumps where abrasives are always an issue. GM 860 also handles the limited run dry requirement of these applications. It was developed to replace traditional pump materials, which are prone to damage from highly-abrasive suspensions. Traditional pump bushings (bronzes and other plastics) do not handle run dry situations well. This new material extends the range of Graphalloy run dry capable materials into additional applications, enabling users to increase MBTF (mean time between failures) in many pumps troubled by abrasives. The bearings are supplied machined and ready to install. The company, established in 1913, also produces Graphalloy® a graphite/metal alloy bearing material used in the manufacture of self-lubricating bearings and components for machinery and process systems.
