Air Operated Double Diaphragm (AODD) pumps are versatile fluid transfer machines designed for conveying or pressurizing various liquids. These pumps efficiently transport water, oil, acid and alkali liquids, emulsions, suspending emulsions, and can handle liquid-gas mixtures and liquids containing suspended solids.

• Non-leakage design for safe operation
• Excellent self-priming performance
• Compatible with various media types
• Available in multiple materials: Cast Steel, Aluminum, Stainless Steel, Polypropylene
• High volume delivery even at low air pressure
• Modular air motor and fluid section design

The air operated diaphragm pump alternately generates intake fluid pressure and positive fluid pressure in the fluid chamber using pressure differences in the air chamber. Ball valves ensure forward fluid flow direction. Pump cycling begins when air pressure is applied and continues to meet demand, building and maintaining line pressure automatically.
