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 500°F (260°C). 

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 counterparts 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.

Features and Benefits 

• Superior dry run properties to increase MTBR. Due to  its three-dimensional carbon fiber reinforcements,  WR® 650 can handle 2.5x higher dry wear conditions  compared to other PFA composites. 

• Value engineered to deliver a low total cost of  ownership vs. competitive products. 

• Enhanced vibration dampening capability extends  reliability and the lifetime of the pump. 

Applications 

• Pump applications in refineries, chemical plants,  power plants, and water treatment plants. 

• Centrifugal pumps (overhung, vertical in-line,  single-stage between bearings, multi-stage  horizontal, vertical, etc.).
