Air Operated Double Diaphragm Pumps
Air operated double diaphragm pumps, also called AODD pumps, are positive displacement pumps that feature two flexible diaphragms connected by a shaft. An air valve delivers compressed air to one of the diaphragms, causing it to pull to one side. This action causes the second diaphragm to shift as well, creating suction. The compressed air alternates between feeding into and venting out of the pump; as the diaphragms move back and forth, they create a pumping action that draws fluids in and expels them through the pump.
Double diaphragm pumps are self-priming and typically used in low-pressure fluid transfer applications. They are compatible with dirty, contaminated, and viscous fluids and used for applications such as:
- Acid transfer metering
- Food processing
- Gels or creams
- Slurries and sludges
- Volatile solvents

Features and Benefits of Air Operated Double Diaphragm PumpsDouble-diaphragm pumps are highly versatile and designed to handle tough jobs like pumping chemicals, slurry, concrete or barrels of water. They provide an efficient, low maintenance solution for a range of industrial applications including mining, oil & gas, wastewater treatment, pulp and paper, and pharmaceutical. Since AODD pumps use compressed air instead of electricity, they are safe to use with and around hazardous substances.
Air operated double diaphragm pumps are relatively easy to set up and relocate for different application uses throughout your plant. They are practically leak-free and can run dry since they do not contain internal seals or components that require lubrication.
For the pump function properly, the pressure of the compressed air supply must be equal to or greater than the pressure of the substance being pumped. Double diaphragm pumps are also noisier and create more vibrations than mechanical pumps. Therefore, they should not be used near sensitive machinery or devices.
