AODD | ARO Pumps & Parts

ARO air-operated double diaphragm (AODD) pumps are versatile industrial pumps used across manufacturing, chemical processing, maintenance, finishing, water treatment, and general fluid-transfer applications. Their air-powered design allows flow to be adjusted through the air supply and can make them suitable for intermittent duty, portable transfer, tank unloading, circulation, and other demanding tasks. AODD pumps are available in different sizes, body materials, diaphragm materials, and connection configurations. Depending on the model, they can handle clean liquids, viscous materials, fluids with suspended solids, coatings, oils, chemicals, and wastewater. The absence of an electric motor directly on the pump can also simplify use in certain process environments when the complete installation is correctly designed. Choosing an ARO AODD pump requires matching the pump to the fluid and application. Consider chemical compatibility, flow requirement, discharge pressure, suction lift, viscosity, solids size, temperature, air availability, and connection size. Browse ARO AODD pump models to compare technical details and select the configuration that best fits your system. Always verify the complete model number before purchasing replacement equipment or service components.
