The Benefits of an Air-Operated Double-Diaphragm Pump (AODD)

The Air-Operated Double-Diaphragm Pump (AODD) is a type of positive displacement pump that many operators prefer over standard centrifugal pumps for certain thick and viscous fluid applications. AODDs are commonly used in industries like food processing, electronics, pharmaceuticals, paints and oil, acid transfer metering, and gas.
Four key benefits of Air-Operated Double-Diaphragm pumps:

  • Simple Design
    Because they don’t have any rotating, sliding or tightly fitting parts, AODD pumps require minimal assembly. Once connected to the compressed air line, they can be used immediately and require little maintenance during operation. They offer a sealless design and have dry-run capabilities. Also, they can be deadheaded and don’t use oil or other lubricants, so they won’t stall or clog.


  • Discharge Flexibility
    Some AODD pumps are capable of flow rates as slow as one gallon per minute. The gentle motion of the compressed-air pumping motion makes them ideal for handling sensitive media, as well as highly viscous or thick liquids that can be problematic for other pumps. Air-Operated Double-Diaphragm pump sizes can range from 0.25 to four inches. Consult our website to determine the right size and configuration for your plant.


  • Safety
    AODD pumps run on compressed air, meaning there’s no motor, no electricity and no fuel, which creates a safer environment for workers. They’re also fully sealed units, which means they can be completely or partially submerged directly in a liquid. AODD pumps provide minimal risk of media contamination, making them highly preferred in the food and beverage industries.


  • Versatility & Customization
    AODD pumps can be constructed from many different materials. This makes them extremely versatile for a wide range of applications—from clean water to fluids containing 90 percent solids. Air-Operated Double-Diaphragm pumps are easy to customize and offer nearly limitless possibilities for flow rate, pressure, media, and more.
