A.R. Wilfley & Sons

A.R. Wilfley and Sons, Inc., founded in 1919 in Denver, Colorado, engineers and manufactures abuse-tolerant, heavy-duty centrifugal pumps designed for continuous duty and maximum uptime in some of the most hostile environments in the world. The company was established by Arthur Wilfley and his two sons on the strength of his invention of the packingless centrifugal pump, a pioneering design that remains central to Wilfley's waterless sealing technology.

Its product range covers slurry pumps and chemical pumps combining robust hydraulic design, waterless sealing systems and wear-resistant materials for mining, fertilizer, chemical and food processing industries, with proprietary metallurgy and seal innovations that eliminate gland water requirements. Wilfley backs its pumps with legendary customer support — experienced sales engineers, high-quality parts and rebuild programs — serving customers across dozens of global industries from its US manufacturing base.
