As a U.S.-registered supplier of advanced process control and automation hardware, ATO empowers plant managers and design engineers with reliable, cost-effective equipment. We believe that top-tier industrial control systems should be accessible without inflated agent margins, which is why we deliver factory-direct solutions that directly reduce capital expenditure. Every system from ATO is paired with free expert technical support, providing full engineering assistance on product sizing, electrical control wiring, and field troubleshooting before and after installation.

In demanding process applications, ATO’s Air Operated Double Diaphragm Pumps (AODD Pumps) stand out for their positive displacement design and pneumatic reliability. Utilizing dual diaphragms and positive-displacement ball valves, our air-driven pump portfolio covers port sizes from 3/8 inch to 5 inches, delivering variable flow rates from 5 GPM for precise metering up to 275 GPM for large-scale transfer. Because these pumps operate entirely on compressed air rather than electrical power, they generate zero thermal buildup and eliminate static spark hazards in sensitive environments.

The seal-less architecture of ATO AODD pumps removes the need for dynamic shaft seals, completely preventing costly gland leaks when pumping volatile, toxic, or abrasive fluids. Their low-shear pumping action ensures that shear-sensitive media—such as emulsions, polymers, food slurries, and delicate chemical solutions—are transferred without degradation or agitation. With built-in self-priming capabilities, dry-running allowance, and corrosion-resistant body options like stainless steel and non-metallic synthetics, ATO provides a long-lasting fluid handling platform for modern plants.
