Wilden® Energy Efficient AODD Pumps, Air Distribution Systems, Diaphragms and Accessories: Durability, Reliability and Cost Savings

In 1955, Jim Wilden revolutionized the pumping industry by inventing the air-operated double-diaphragm (AODD) pump and establishing the Wilden Pump & Engineering Company. Today, Wilden remains the trustworthy industry leader in AODD pumps thanks to a dedication to pioneering new innovations while providing unparalleled excellence in customer satisfaction. Thanks to this innovative and customer-focused culture, the Wilden family of AODD pumps has been able to prove its rugged durability and reliable performance in countless installations.

Not only are Wilden pumps the most cost-effective, reliable and energy-efficient solutions available, but our state-of-the-art air distribution systems (ADS) significantly increase positive displacement pump productivity by reducing air consumption and maintenance for the most energy-efficient AODD pump operation possible.
