AODD Pumps (Air Operated Double Diaphragm Pumps) South Africa & Africa
Air Operated Double Diaphragm or AODD pumps, also known as diaphragm pumps, are widely used across South Africa and Africa for handling challenging fluids in industrial, mining, chemical, and agricultural applications. These pumps are known for their reliability, versatility, and ability to handle abrasive, viscous, and corrosive liquids.
At Pumps Africa, we supply high-quality AODD pumps designed for demanding environments where conventional pumps may fail. Whether you need to transfer chemicals, slurry, waste fluids, or food-grade liquids, we can help you select the right diaphragm pump for your application.
What Is an AODD Pumps?
An AODD pump is a positive displacement pump that uses compressed air to move fluid through flexible diaphragms. As the diaphragms move back and forth, they create suction and discharge cycles that transfer liquid efficiently.
Unlike centrifugal pumps, AODD pumps do not rely on high-speed rotation. This allows them to handle a wide range of fluids, including those that are thick, abrasive, or sensitive to shear.
AODD pumps are commonly used in situations where:
- Electric power is not ideal or safe
- Fluids are aggressive or difficult to pump
- Reliable, low-maintenance operation is required
Key Advantages of AODD Pumps
AODD pumps are popular across industrial sectors because of their flexibility and durability.
Handles a wide range of fluids
Suitable for clean liquids, sludge, slurry, chemicals, and viscous materials.
Self-priming capability
Can run dry without damage and start pumping without manual priming.
Air-driven operation
No electrical components required, making them safe for hazardous environments.
Low maintenance
Simple design with fewer moving parts compared to other pump types.
Portable and versatile
Can be used in multiple applications with minimal setup.
Choosing the Right Diaphragm Pump
Selecting the correct AODD pumps is critical for performance and longevity.
Key factors to consider:
Flow rate (capacity)
The volume of liquid you need to move over time.
Fluid type
Consider whether the liquid is:
- Corrosive
- Abrasive
- Viscous
- Food-grade
Air supply
Ensure sufficient compressed air pressure and volume are available.
Material compatibility
Pump materials (e.g., aluminium, stainless steel, plastic) must match the fluid.
Operating environment
Temperature, pressure, and location all affect pump selection.

Applications Across South Africa & Africa
AODD pumps are widely used across industries due to their versatility.
Common applications include:
- Mining and slurry transfer
- Chemical processing and handling
- Wastewater and effluent systems
- Food and beverage processing
- Paints, coatings, and adhesives
- Agriculture and fertiliser transfer
Across Africa, these pumps are particularly valuable in environments where durability and flexibility are essential.
Types of AODD Pumps
Different applications require different configurations and materials.
Metallic Diaphragm Pumps
- Made from aluminium, stainless steel, or cast iron
- Suitable for heavy-duty industrial use
- Ideal for abrasive and high-pressure applications
Plastic Diaphragm Pumps
- Made from polypropylene or PVDF
- Resistant to chemicals and corrosion
- Ideal for chemical and wastewater applications
High-Flow AODD Pumps
- Designed for large volume transfer
- Used in industrial and mining operations
Common AODD Pump Problems
While AODD pumps are reliable, issues can occur if the system is not correctly set up.
Common problems include:
- Reduced flow or pressure
- Air leaks in the system
- Diaphragm wear or failure
- Incorrect air supply settings
These issues are usually caused by incorrect sizing, material selection, or maintenance practices.
