Consider Vespel® CR-6100 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 Vespel® CR-6100, you can eliminate the metal-to-metal contact points in the pump. The stationary components are converted to Vespel® CR-6100 and the rotating parts remain metal, creating a metal-to-composite interface. This helps the pump:

  • Avoid pump seizure
  • Avoid galling during alignment, slow-roll, or start-up
  • Survive run dry conditions

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

  • Increased pump efficiency
  • Improved rotor stability
  • Reduced vibration
  • Reduced shaft deflection
  • Reduced risk of cavitation

In both cases, the low friction and dimensional stability of Vespel® CR-6100 offer very low wear rates and long service life.
