The Story Behind WILDEN Air-Operated Double Diaphragm Pumps

The Story Behind WILDEN Air-Operated Double Diaphragm Pumps

In industrial innovation, great technologies are often born from real-world challenges. The creation of WILDEN air-operated double diaphragm pumps (AODD) is a remarkable example of solving practical problems through engineering innovation.

In 1955, American engineer Jim Wilden developed a new pumping technology after encountering difficulties with traditional pumps in demanding working environments. He created a pump driven by compressed air, using flexible diaphragms to transfer fluids safely and efficiently. This breakthrough became the foundation of modern AODD pump technology.

Over the decades, WILDEN pumps have been widely used in chemical processing, mining, food and beverage, pharmaceutical, environmental protection, coatings, and other industries, becoming a trusted solution for challenging fluid transfer applications.

Advanced Materials for Reliable Performance

WILDEN AODD pumps are available in a variety of materials to meet different operating conditions:

Engineering Plastics:
Materials such as polypropylene (PP) and PVDF provide excellent chemical resistance for handling corrosive liquids.

Metal Construction:
Aluminum and stainless steel versions offer high strength, durability, and reliability for heavy-duty industrial applications.

Sanitary Design:
Stainless steel models are suitable for industries requiring high cleanliness standards, including food, beverage, and pharmaceutical applications.

The diaphragm is the core component of the pump. WILDEN offers different diaphragm materials, including PTFE, Santoprene®, Buna-N, and EPDM, allowing users to select the ideal solution based on chemical compatibility, temperature, and wear resistance.

Key Advantages of WILDEN AODD Pumps
