WR® 650 is a next-generation PFA composite reinforced with a three-dimensional carbon-fiber architecture. This material offers superior dry run capability, excellent wear and chemical resistance, and an operating temperature range up to 260°C (500°F). The advanced mechanical, thermal, and tribological properties of WR® 650 provide increased operating efficiency and improved MTBR (mean time between repair). WR® 650’s non-galling/non-seizing characteristics, and its ability to dampen vibrations, allow for tighter clearances compared to traditional metallic components, and increased efficiency. The malleable nature of PFA ensures metallic counter-parts are preserved, even those that are relatively soft (SS 304 or 316). This helps extend the service life of pumps and improves equipment reliability. WR® 650 is available in a broad range of stock shapes, providing customers the ability to machine parts to their exact specifications.
