ARO® first introduced its air-operated double diaphragm (AODD) pump to the market in the 1980s in Bryan, Ohio, USA. Today, ARO® is part of Ingersoll Rand Corp. and is one of the leading AODD pump brands worldwide.
ARO® air-operated diaphragm pumps can handle a wide range of viscous fluids and operate continuously without freezing. Their unbalanced air valve design prevents the stalling issues common with other pumps. Rapid exhaust valves redirect cold exhaust air away from freeze-prone components, preventing icing. Depending on the fluid type, multiple pump configurations are available — including single-body, double-body, and heavy-duty double-body piston pump packages.
ARO® diaphragm pumps are a cost-effective and reliable choice for industrial and chemical applications. Their bolted, leak-proof design eliminates cross-contamination and enhances operator safety. The modular construction, reduced part count, and easy-to-use repair kits minimise downtime when maintenance is required.
