EGC Critical Components has announced its dures™ brand of materials - a new family of proprietary thermoplastic polymer composites developed specifically for the manufacture of bushings, bearings and wear rings in pumps handling a wide range of liquids.

dures A451 produced from chop carbon fiber and reinforced compression molded PEEK is used in the manufacture of bushings, bearings and wear rings with excellent chemical resistance, non galling and non seizing properties. But it is not suited for abrasive applications or operating temperatures above 275°F. In comparison, dures™XPC2, formulated from continuous carbon fiber with PEEK base polymer, is recommended and approved for operating temperatures up to 550°F making it most appropriate for use in boiler feed and process pumps. dures™A451 and XPC2 have been successfully used by industry for decades.

"Pump operators using dures™ materials can now set much tighter equipment clearances, enhancing efficiency and savings in life cycle costs," says Michael Boylan, General Manager for EGC. "Also, because we have a laboratory and testing facility on the same campus as our manufacturing centre, we have full control over the design, specification, quality and performance of materials. For applications where the slightest variance can produce unacceptable results, this ensures the highest standards are always met."
