ATO is a trusted U.S.-registered supplier dedicated to modernizing industrial automation supply chains. By establishing direct connections between plant operators and top Chinese manufacturers, ATO eliminates intermediary markups to maximize your return on investment. Our team of skilled engineers provides complimentary technical support, guiding plant personnel through equipment wiring, sizing, and commissioning to ensure zero downtime.

To optimize plant fluid handling, ATO offers advanced Air Operated Double Diaphragm Pumps (AODD) designed for maximum energy efficiency and minimal maintenance. Operating on compressed air, these pumps automatically stop when outlet pressure equalizes, consuming zero energy when idle. Available in inlet/outlet sizes from 3/8" up to 5", they deliver flows between 5 GPM and 275 GPM at pressures up to 120 PSI across aluminum, stainless steel, cast steel, and non-metallic body options.

Built without dynamic seals, ATO AODD pumps eliminate fluid leakage and reduce maintenance downtime caused by seal wear. Their self-priming and submersible capability makes them ideal for automated wastewater sumps, chemical dosing lines, and BioFloc water treatment setups. With easy port alignment and simple bolt assembly, ATO pneumatic pumps offer plant managers a compact, energy-efficient solution for continuous fluid transfer.
