Air-Operated Double Diaphragm (AODD) pumps are often a popular choice for fluid-handling tasks across a hugely diverse range of industries. Since it’s invention in 1955, AODD pumps are known for their simple design characteristics, sealless operations and its ability to run dry and self-prime.

AODD pumps rely on compressed air for its operation. Compressed air is alternately fed to, and vented from, air chambers on the opposite sides of the diaphragms to create the pumping action.

Advantages of AODD pumps


  • Minimal assembly/disassembly; Easy to install, operate, clean and repair.
  • Ability to run dry without damaging internal wear parts
  • Lightweight and portable; Ideal for use in multiple locations
  • Inexpensive mechanical parts and shorter downtime


  • Various levels of customization are available (sizes, material of construction)
  • Wide range of mediums ranging from highly viscose fluids; abrasive, corrosive chemicals; solids handling, sludge, slurries, etc.

Safe Operation:

  • Reliable prevention of leakages and possible harm (ie hazardous liquids)
  • Driven by air, eliminating the risk of a short circuit or liquid penetrating through the electrical wiring
