What Is a Wilden Air Operated Diaphragm Pump?

A Wilden air operated diaphragm pump is a positive displacement pump powered by compressed air. It features two flexible diaphragms that move in tandem to draw fluid into and out of the pump chamber via check valves. With no rotating parts in the fluid path, these pumps are ideal for transferring shear-sensitive, viscous, or corrosive materials.

The Wilden brand is renowned for its innovative Pro-Flo® SHIFT air distribution system, which dramatically reduces air consumption while improving flow rates. If you’re looking for a rugged pump with low maintenance and maximum uptime, Wilden is the name to trust—and MultiTorque is your go-to provider.
