Our dures® brand of proprietary thermoplastic polymer composite materials has proven successful in improved pump reliability, increased efficiency, reduced maintenance costs, increased mean time between failures, and reduced equipment downtime.

dures® materials were developed specifically for use as bushings, bearings, shaft sleeves, and wear rings in pumps handling a wide range of liquids including those that contain solid particulate often abrasive matter. The unique properties of dures® materials enable component designs with tighter clearances – improving reliability, enhancing efficiency, and savings in life cycle costs. Additionally, the proprietary formulation of our dures® products substantially reduces contact damage and surface galling during touch-off events in the pump system.

With thousands of successful applications, major OEMs are experiencing long-term benefits from the dures® advantage: 

  • Outstanding performance
  • Durable wear characteristics
  • Excellent abrasive resistance
  • Dry run capability
  • Superior vibration dampening with negligible hydrolysis or part deformation
  • Excellent dimensional stability
