Move industrial fluids reliably with genuine ARO air operated double diaphragm pumps. Also known as AODD pumps or pneumatic diaphragm pumps, these compact 1/2-inch pumps use compressed air to transfer liquids without requiring an electric motor at the pump.

The range includes metallic and non-metallic configurations designed for chemical transfer, fluid dispensing, circulation, lubrication systems, OEM equipment and general industrial liquid handling. With multiple construction and elastomer options available, each pump can be matched more closely to the fluid, operating temperature and application requirements.

Compact 1/2-Inch AODD Pumps

ARO 1/2-inch diaphragm pumps deliver high transfer performance in a compact package suitable for equipment skids, production systems and installations with limited space.

Depending on the selected model and configuration, these pumps provide:

• Flow rates up to 14.4 GPM (54.5 L/min)
• Maximum discharge pressure up to 100 psi (6.9 bar)
• 1/2-inch threaded fluid connections
• Solids handling up to 3/32 inch (2.4 mm) on applicable models
• Air-powered, seal-less double diaphragm operation
• Compact construction for OEM and industrial installations

The category includes Classic Series 66605 pumps with flow rates up to 13 GPM, as well as PD05 compact diaphragm pumps with flow rates up to 14.4 GPM.

Metallic and Non-Metallic Pump Configurations

Choose from polypropylene, groundable acetal and aluminum pump constructions, depending on the required chemical compatibility, durability and operating environment.

Non-metallic ARO diaphragm pumps are commonly selected for chemical transfer and applications requiring corrosion-resistant wetted components. Groundable acetal configurations provide an option for applications in which static dissipation is an important consideration.

Aluminum pumps provide a durable metallic solution for oils, lubricants and general industrial fluid-transfer duties. Available ball, seat and diaphragm combinations allow the pump configuration to be matched to the characteristics of the fluid being transferred.

Always confirm the compatibility of the complete pump configuration with the fluid composition, concentration, temperature, solids content and operating conditions.

Benefits of ARO Pneumatic Diaphragm Pumps

ARO AODD pumps are designed to provide dependable operation and straightforward maintenance in industrial fluid-handling systems.

Key benefits include:

• Compressed-air operation without an electric pump motor
• Compact size for space-restricted installations
• Metallic and non-metallic construction options
• Multiple wetted-material configurations
• Reliable transfer of a wide range of industrial liquids
• Suitability for transfer, circulation, dispensing and OEM applications
• Genuine ARO service parts and fluid-section repair kits

Find the Right ARO AODD Pump

Compare each pump by flow rate, pressure, body material, ball material, seat material, diaphragm material and fluid-port configuration. Selecting the correct wetted materials is essential for dependable performance, safe operation and longer service life.

Shop genuine ARO air operated double diaphragm pumps and choose the configuration that best fits your industrial fluid-transfer application.
