Air Operated Diaphragm Pumps

Air Operated Diaphragm Pumps (AODD) are ideal for handling a wide range of viscous, abrasive, and shear-sensitive liquids with minimal maintenance. Powered by compressed air, AODD pumps offer self-priming capabilities and the flexibility to operate in hazardous environments.

  • Air Operated Diaphragm Pumps (AODD) are versatile, self-priming, positive displacement pumps powered by compressed air. Their simple, robust design features two flexible diaphragms that move back and forth to draw in and expel fluid, making them ideal for handling challenging fluids, including slurries, abrasives, and corrosive chemicals. AODD pumps can run dry, handle solids, and are suitable for hazardous environments, offering safe and reliable operation without the need for electricity.


    KEY BENEFITS OF AODD PUMPS INCLUDE:

    • Self-priming and dry-run capable

    • Excellent chemical and abrasion resistance

    • Handles viscous, shear-sensitive, and solid-laden fluids

    • Explosion-proof by design (ATEX options available)

    • Easy to install, operate, and maintain

    • Portable and adaptable to remote or mobile systems
