Greene, Tweed (Kulpsville, Pa.) has expanded its WR high-performance thermoplastic composite portfolio with its newest material, WR600. Designed for use in wear parts, bushings and bearings for petrochemical and power pumps, the material is said to offer almost universal chemical compatibility and extended dry-run capabilities. Features include non-galling and non-seizing properties, allowing close bearing and wear-ring clearances to increase efficiency, reduce vibration and enhance reliability. The material offers higher resistance to thermal shock and impact than ceramics, as well as thermal expansion coefficients well-matched to stationary wear-ring applications.
