Air-Operated Diaphragm Pump (AODD Pump)

Air-Operated Diaphragm Pumps (AODD Pumps) are positive displacement pumps powered by compressed air, designed for the safe, reliable, and efficient transfer of a wide range of fluids. These pumps are especially suitable for applications where hygiene, safety, and gentle product handling are critical.

AODD pumps operate using flexible diaphragms that move fluid without direct contact with moving mechanical parts. This design provides leak-free operation, excellent self-priming capability, and the ability to run dry without damage. As they do not require electrical power, air-operated diaphragm pumps are ideal for hazardous, explosive, or wet environments.

Available in sanitary and industrial configurations, these pumps are widely used in food, dairy, beverage, pharmaceutical, chemical, cosmetic, and general industrial applications.
