Air-Operated Double-Diaphragm (AODD) Pumps

• ARO’s AODD pumps are a core product: self-priming, capable of dry-run operation, and suitable for transferring a wide range of fluids — from low-viscosity liquids to abrasive or solids-laden media.
• Available in many sizes (from ¼" up to 3") and construction materials (metallic or non-metallic), offering flexibility to match chemical compatibility, viscosity, and application requirements.
• AODD pumps handle fluids for chemical processing, general manufacturing, industrial transfer, wastewater, abrasive or corrosive media — catering to many industries globally.

Electric & Piston Pumps

• For applications where electric power is preferred, ARO offers electric diaphragm pumps — delivering positive displacement performance without the need for compressed air.
• ARO piston pumps and pump packages are available for high-pressure fluid transfer, grease, oils, coatings or viscous fluids — useful when higher discharge pressures or more robust pumping is required.

Fluid Handling & Pneumatic Accessories

• Beyond pumps, ARO supplies lubrication equipment, pneumatic valves, filters, regulators and lubricators (FRLs), and motion-control components — enabling full fluid-handling or compressed-air systems from a single source.
• This makes ARO a versatile supplier for industries requiring integrated fluid and air handling solutions — from chemical plants to industrial manufacturing.

Industries & Typical Applications
ARO pumps and systems are employed across many sectors due to their flexibility, robustness and broad fluid compatibility:

• Chemical processing, including aggressive or corrosive fluids
• Manufacturing and general industry fluid transfer and handling
• Mining, energy, and heavy-duty industrial operations where durable, reliable pumping is required
• Pharmaceutical, cosmetics, food & beverage — especially where hygienic or controlled fluid transfer is needed (with suitable materials and diaphragm options)
• Grease and lubricant dispensing, oil transfer, coatings, paints, sealants and similar fluids via piston or lubrication-focused pumps and packages

• Proven heritage & reliability: Over 90 years of experience delivering robust fluid-handling solutions worldwide.
• Broad product range: From AODD diaphragm pumps and electric diaphragm pumps to piston pumps, lubrication systems, and pneumatic accessories — covering virtually any application need.
• Versatile fluid compatibility: Able to handle a wide spectrum of fluids — from light chemicals and solvents to abrasive slurries, viscous oils, and solids-bearing media.
• Flexible configurations & materials: Multiple pump sizes, metallic and non-metallic options, and a wide selection of accessories for customised systems.
• Efficient total cost of ownership: Reliable performance, modular design, and strong support network make ARO a cost-effective choice for long-term operations.
