If you need a pump that can handle anything from corrosive chemicals to abrasive slurries—all without relying on electricity—then you need an AOD pump (Air Operated Diaphragm pump). Built for versatility and rugged performance, these pumps are the unsung heroes of mining sites, wastewater plants, chemical factories, and more.

At MultiTorque, we don’t just supply off-the-shelf units—we custom-engineer AOD pumps, mount them to trailers or skids, power them with compressors, and keep them running with expert servicing. When reliability matters, we deliver.

What Is an AOD Pump?

An AOD pump, or air-operated diaphragm pump, is a type of positive displacement pump powered by compressed air. It moves fluids by expanding and contracting two flexible diaphragms in tandem, pushing fluid in and out through a series of one-way check valves.

Because there are no electrical components in the fluid path, AOD pumps can safely handle flammable, volatile, abrasive, and highly viscous fluids—making them essential in dangerous or remote worksites.

Key Benefits of AOD Pumps

AOD pumps are known for their toughness and adaptability. Here’s why so many industries rely on them:

• Explosion-Proof Operation: No electrical motor = safe for hazardous zones

• Self-Priming & Run-Dry Safe: No pump damage if dry-started

• Handles Solids & Slurries: Perfect for mud, sludge, and debris-laden fluids

• Portable & Compact: Easily mounted to trailers or skids

• Low Maintenance: Minimal moving parts, no mechanical seals

• Variable Flow Rates: Output adjusts based on air pressure input

Whether you’re pumping corrosive acids, wastewater sludge, or fuel, an AOD pump can do the job safely and efficiently.
