Wilden Air Operated Diaphragm Pumps


In 1955, Jim Wilden revolutionized the pumping industry when he invented the air-operated double diaphragm (AODD) pump.
Since that time, Wilden®, a PSG Dover Company, has forged a long-lasting legacy as the global leader in AODD pump technology. Thanks to a dedication to pioneering new innovations while providing unparalleled excellence in customer satisfaction, Wilden’s family of AODD pumps is unmatched in reliability, durability, efficiency, and performance.
Wilden’s commitment to the customer is undoubtedly the reason why they are the market leaders in the industry. They listen to the comments of engineers, maintenance personnel, and end users to develop general and specialized products to meet your needs. Wilden is constantly in the pursuit of excellence, always innovating and designing new products.

As a result, Wilden Air Operated Diaphragm pumps are widely respected as the most versatile pump on the market today. Air powered, these pumps are able to pump thick and thin liquids, solids laden and abrasive liquids and can dry run, dead-head and work submerged or dry mounted.
