Thermoplastic Polymer Composites enhance pump versatility.

Press Release Summary:

Available to address maintenance, upgrade, and repair needs of pumps operating in such demanding environments as refineries, chemical plants, and pipelines, dures™ thermoplastic polymer composites are suited for manufacture of bushings, bearings, and wear rings in pumps handling various liquids (including those that contain solid matter). With respective max temperature ranges up to 150 and 250°F, dures 150 and 250 meet need for chemical, thermal shock, impact, and abrasion resistance.

EGC Announces New dures(TM) Brand of Thermoplastic Polymer Composites for Pumps

Advanced material increases reliability and efficiency in a wide range of liquid pump applications

HOUSTON -- EGC Critical Components, a leading manufacturer of high-performance thermoplastic performance-critical components, today announced its dures(TM) 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, including those that contain solid matter. The new material, produced exclusively by EGC, is in stock and immediately available to address the maintenance, upgrade and repair needs of pumps operating in a wide range of performance demanding environments including refineries, chemical plants and pipelines. In the refinery environment, EGC estimates that approximately sixty percent of pumps currently in operation can benefit from this material.

The dures(TM) family of polymer solutions for pump applications includes four products with unique performance characteristics: dures(TM)150, dures(TM)250, dures(TM)A451 and dures(TM)XPC2. dures(TM)150 and 250 are the most recent additions to this family of composite formulations. They were developed to meet the need for outstanding chemical, thermal shock and impact and abrasive resistance, with a temperature range of 150F and 250F. dures(TM) 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.

dures(TM)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 275F. In comparison, dures(TM)XPC2, formulated from continuous carbon fiber with PEEK base polymer, is recommended and approved for operating temperatures up to 550F making it most appropriate for use in boiler feed and process pumps. dures(TM)A451 and XPC2 have been successfully used by industry for decades.

"Pump operators using dures(TM) 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 center, 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."

A multi-disciplined engineering team with a depth of experience using a wide variety of advanced materials provides an added benefit for pump operators using dures(TM) materials.

"We focus on the science of polymer materials. The work we do in our laboratory and testing facilities is a powerful resource for innovation and future success, and this sets us apart from other manufacturers," says Kurt Hayden, Director of Engineering and Technology Development for EGC. "Continuous investment in material development and testing ensures our use of the latest achievements and technology to help industry reach ever-increasing performance demands and objectives."
