EGC Critical Components introduces Dures brand of materials - a new family of thermoplastic polymer composites developed specifically for the manufacture of bushings, bearings and wear rings in pumps handling a wide range of liquids, including those that contain solid matter. The new material addresses the maintenance, upgrade and repair needs of pumps operating in demanding environments including refineries, chemical plants and pipelines.
The Dures family of polymer solutions for pump applications includes four products: Dures150, Dures250, DuresA451 and DuresXPC2. Dures150 and 250 provide chemical, thermal shock and impact and abrasive resistance, with a temperature range of 150˚F and 250˚F. Dures polymers provide greater wear performance than many other materials such as rubber or bronze, offer superior abrasive resistance, dry run capability and vibration dampening with negligible hydrolysis or swell, according to EGC.
DuresA451, produced from chop carbon fiber and reinforced compression molded PEEK, is used in the manufacture of bushings, bearings and wear rings with chemical resistance, non galling and non seizing properties. It is not suited for abrasive applications or operating temperatures above 275˚F. DuresXPC2, 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.
