An Air Operated Diaphragm Pump (AODD) is a type of positive displacement pump that uses compressed air to move fluids. It consists of two flexible diaphragms that alternate in motion, creating a vacuum that draws fluid into the pump and then expels it through a discharge outlet. This design allows for efficient handling of various liquids, including slurries and viscous materials. AODD pumps are known for their versatility and portability, making them suitable for a wide range of applications in industries such as chemical processing, food and beverage, and water treatment. They can operate dry without damage and are often used in environments where electrical equipment may pose a risk.
