Abrasion-resistant bushing material for pumps

Graphlon GM 860 is a polymer and graphite-based which has been developed specifically for sump pumps and river water service pumps where abrasives are always an issue. The material also handles the limited run dry requirement of these applications.

Graphite Metallizing says that Graphlon GM 860 was developed to replace traditional pump materials which are prone to damage from highly-abrasive suspensions. Traditional pump bushings (such as bronzes and other plastics) do not handle run dry situations well.

This new material extends the range of the company's Graphalloy run dry capable materials, enabling users to increase mean time between failure with many pumps troubled by abrasives. The bearings are supplied machined and ready to install.
