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.
