Wilden’s legendary Original™ Series pumps were designed for demanding utilitarian type of applications that require a robust design. The clamped configuration is a classic design that evolved from 1955 with the invention of Jim Wilden’s first air operated double diaphragm pump. The Original™ Series pumps ensure reliability without sacrificing ease of maintenance. The metal pump line lends itself to various processes and waste applications in a multitude of materials consisting of cast iron, aluminum, stainless steel and alloy C.  Elastomers that are available are Buna-N, Neoprene, Viton, Wilflex, Polyurethane and Teflon to meet your abrasion, temperature, and chemical compatibility concerns.

Wilden’s revolutionary Advanced™ Series pumps were specifically designed for maximum performance and efficiency. The bolted configuration of these pumps ensures total product containment while the redesigned liquid path reduces internal friction to maximize output and efficiency. A variety of materials are available to meet abrasion, temperature, and chemical compatibility concerns. The Advanced™ Series metal pumps are offered in die cast aluminum, stainless steel and alloy C. Elastomers that are available are Buna-N, Neoprene, Viton, Wilflex, Polyurethane and Teflon.  A variety of options such as ANSI and DIN flanges and specialized air distribution systems are available to meet your specific application requirements.
