An AODD Pump (Air Operated Double Diaphragm Pump) is a type of positive displacement pump that uses compressed air as a power source. It operates by moving two flexible diaphragms back and forth, creating a pumping action that draws in and expels fluid. AODD pumps are known for their versatility, as they can handle a wide range of fluids—including viscous, abrasive, and corrosive liquids—without the need for electricity. They are commonly used in industries such as chemical processing, wastewater treatment, mining, and food and beverage, due to their durability, self-priming ability, and dry-run capability.
