Air Operated Diaphragm Pumps Built to Perform: Reliable Supply, Repairs & Custom Solutions

Air Operated Diaphragm Pumps

When reliability is non-negotiable, the air operated diaphragm pump (AOD pump) is a trusted choice across countless industries. Tough, self-priming, and capable of handling everything from chemicals to sludge, these versatile pumps thrive where others fail.

At MultiTorque, we supply, service, and custom-configure air operated diaphragm pumps to keep your operation flowing. With over 15 years of experience and a deep understanding of industrial pumping challenges, we deliver solutions that last.

What Is an Air Operated Diaphragm Pump?

An air operated diaphragm pump is a type of positive displacement pump powered by compressed air. Instead of electric motors, it uses a clever system of air valves and flexible diaphragms to create suction and discharge pressure.

These pumps are particularly useful when you need:

  • Explosion-proof pumping (no sparks)

  • Dry-run capability

  • Self-priming up to 6 meters

  • Low-shear fluid transfer

  • Abrasive or corrosive fluid handling

  • Portability and compact design

AOD pumps excel in mining, wastewater, food processing, chemicals, paint, fuel, and just about any harsh environment where uptime is critical.
