Wilfley

What Wilfley does

Wilfley (legal entity A.R. Wilfley & Sons, Inc.) is a fifth-generation, family-owned industrial pump manufacturer founded in 1919 in Denver, Colorado, now headquartered and primarily producing in Commerce City, CO. The company designs and builds heavy-duty centrifugal slurry and chemical pumps (current models EMW, Kpro, HD; A9, A7, S3 Acid Slurry; plus legacy K, AG, AF) for abrasive and corrosive service in mining, chemical processing, fertilizer, food processing, and miscellaneous industrial sectors. Its core technical differentiation is a waterless sealing system — a dynamic expeller seal combined with either a SolidLock or DryLock static seal — invented by founder Arthur Redman Wilfley over a century ago and continuously refined (DryLock 3 launched 2015). Pump performance is reinforced by proprietary metallurgy (MAXALLOY 5A hard iron, WCD4 duplex stainless steel, Alloy C Max, Alloy G) produced in-house at wholly-owned subsidiary Western Foundries, with documented outcomes such as 400% service-life improvements at Codelco Chuquicamata and 1,300% pump-life improvement at Ingenio Manuelita.

The company monetizes through capital equipment sales, recurring spare-parts revenue, and a Pump Rebuild Program that supports every pump it has ever manufactured since 1919. Pricing is quote-based on model, metallurgy, and configuration. Go-to-market combines direct enterprise sales engineers, a global Find-a-Local-Rep network, regional master distributors (Thurston Machine for Canada, Scheel & Company as long-standing rep), and a manufacturing/distribution hub at Wilfley India in Miraj. Named enterprise customers include Grupo Mexico (Buenavista del Cobre), Met Mex Peñoles, Codelco, Innophos Fosfatados de México, Ingenio Manuelita, and Charter Steel. The company is private, has 11-50 employees, has no disclosed funding or external institutional investors, and remains operating under continuous family control.

Core offering

Wilfley designs, manufactures, and sells heavy-duty centrifugal slurry and chemical pumps incorporating its proprietary waterless sealing technology and proprietary metallurgy (developed through its wholly-owned Western Foundries subsidiary). Its pumps and replacement parts are sold to industrial enterprises in mining, chemicals, fertilizer, food processing, and other process industries, with a lifetime support commitment covering every pump the company has manufactured since 1919.

Product overview

Wilfley is a manufacturer of heavy-duty centrifugal industrial pumps featuring proprietary waterless sealing technology. The product portfolio includes three slurry pump models (EMW, Kpro, HD), three chemical pump models (A9, A7, S3 Acid Slurry), and three legacy pump models (K, AG, AF). The core technology consists of waterless sealing systems combining Dynamic Expeller Seal with SolidLock or DryLock Static Seals, along with advanced metallurgy materials including MAXALLOY 5A Hard Iron, WCD4 Duplex Stainless Steel, Alloy C Max, and Alloy G Superalloys. These components work together to provide leak-free, maintenance-reduced operation in mining, chemical, fertilizer, food processing, and other industrial applications. Wilfley and its subsidiary Western Foundries provide the metallurgical expertise and proprietary materials that enable the pumps to handle abrasive slurries and corrosive chemicals with extended service life.
