Consider Composite Materials for Your Problem Pumps

Since 1997, Vespel® CR-6100 has been helping process plants solve pump problems. This section details a range of pump design issues, operational issues, and service conditions where Vespel® CR-6100 has helped hydrocarbon processing plants and other process plants improve their pump reliability.

With engineered composite materials, you can eliminate the metal-to-metal contact points in the pump. The stationary components are converted to Vespel® CR-6100 or Boulden's B-Series and the rotating parts remain metal, creating a metal-to-composite interface. This helps the pump:

Because the risk of seizure is minimized, the clearance at the wear components can be reduced, creating additional reliability and efficiency benefits:

Low friction and dimensional stability of composite materials offer very low wear rates and long service life.
