Air Operated Double Diaphragm Pump (AODD pump) is a positive-displacement pump, which means it moves fluid by trapping a specific volume of fluid and then mechanically forcing it out to the discharge side with the help of compressed air.
In this pump, no electricity is required, which makes it a great “solution” where safe, reliable fluid transfer is needed even when no electricity is available. From waste oil, fuels to mining slurries (dense, fluid mixtures of insoluble solid particles), Macnaught’s AODD pumps are capable of managing aggressive chemicals or high-viscosity lubricant fluids, thus making it the preferred choice for reliable, spark-free operation in hazardous environments.
Macnaught provides professional-grade solutions for Diesel, Oil, Air, and Water with over 75 years of Australian-engineered expertise through its Tampa-based stocking facility. It offers the highest flow rates with the lowest air requirement for the double diaphragm pump in the market.
Macnaught’s Air Operated double diaphragm pumps range is specially built for the USA’s harshest industrial environments, ensuring durability and performance where you need it most.

Benefits of Using Air Operated Double Diaphragm Pumps (AODD pump):-
Integrating an air-operated double diaphragm pump (AODD pump) into your workflow offers several mechanical and operational advantages: -
High Volume Delivery at Low Inlet Pressure: These
pumps deliver high volume as output with low air consumption requirements.
Dry-Run Capability Without Damage: These pumps can
run without fluid for extended periods without damage to the internal components, preventing overheating.
Self-Priming: These AODD pumps can prime from a dry
start without any manual intervention, even when the intake sits above the fluid surface, which simplifies setup and speeds up operation on site.
Variable Flow Control: By simply adjusting the air
supply, operators can precisely control the output and flow rate.
Solids Handling: The design allows for the passage of
solids and abrasive particles, making it ideal for waste oil and slurry applications.
Low Maintenance: With no mechanical seals or motors,
the AODD pump features fewer moving parts, reducing the long-term cost of ownership.
Types of Air Operated Pumps Available: -
Macnaught USA offers a range of Air Operated Double Diaphragm Pumps configurations to suit specific fluid compatibilities:
- Metallic AODD Pumps: Constructed from Aluminium or Stainless Steel for heavy-duty industrial and fuel applications.
- Plastic (Non-Metallic) Pumps: Built from PVDF or Polypropylene for superior chemical resistance against corrosive acids.
- High-Flow Series: Specialised units designed for maximum throughput in waste oil and large-scale fluid transfer.
- Small Port (1/2"): Compact models ideal for OEM applications and precise chemical dosing.
- Large Port (1.5" to 3"): Industrial-sized pumps for high-volume
remediation and wastewater management.
Industrial Applications and Use Cases
- Waste Oil Transfer (Auto Shops & Fleet Services): High-flow air diaphragm pump models are optimised for collecting and moving used lubricants and engine coolants.
- Chemical Processing: PVDF pumps safely handle volatile chemicals and detergents without the risk of corrosion.
- Construction & Mining: Portable units are used to dewater sites or move abrasive slurries in remote, electricity-free locations.
- Environmental Remediation: Ideal for emergency spill cleanup where speed and the ability to handle debris-laden water are critical.
- Food & Beverage: FDA-compliant PTFE components allow for the safe transfer of alcoholic spirits, juices, and dairy

Frequently Asked Questions:-
Q: What is an air-operated double diaphragm pump(AODD pump), and how does it work?
An AODD pump is powered by compressed air. Two flexible diaphragms move alternately back and forth, creating a vacuum and drawing fluid into the pump chamber with consistent, leak-free fluid transfer and displacing it on each stroke, with no electricity required.
Q: Can Macnaught AODD pumps run dry?
Yes. Macnaught Max Flow dual diaphragm pumps are designed to run dry without damage — they do not generate heat when no liquid is present, so an accidental dry run will not harm the pump.
Q: What fluids can a Macnaught air diaphragm pump handle?
The range covers waste oils, fuels, coolants, slurries,mining fluids, hazardous liquids, waste streams, asphalt sealcoating, aggressive acids, caustics, solvents, and food-grade liquids — depending on the body and diaphragm material selected.
Q: What warranty comes with a Macnaught Max Flow AODD pump?
The Max Flow Series carries a 5-year pump body warranty.
Q: Does Macnaught offer repair kits for AODD pumps?
Yes, it provides both "Wet End" and "Air Motor" service kits to ensure the pump remains in peak operating condition.
