Vespel CR-6100 for impeller wear Ring on Boiler Feed pump
We stick with Graphalloy for high temp pumps of all types, including many BFW pumps. The material matches housing thermal expansion and has a much larger temp range than Vespel or other plastics. It also ends up being less expensive.- EFord

Vespel CR-6100 for impeller wear Ring on Boiler Feed pump
why not check out www.graphalloy.com for bushings and bearings? Graphalloy is a graphite metal alloy and they have many years of successful experience in BFW pumps. The material is non-galling, dry-running, dimensionally stable, and is also used for high-temp applications around 750F.- EFord
