AODD Pumps (Air Operated Double Diaphragm Pumps) South Africa & Africa

AODD Pumps or, Air Operated Double Diaphragm, also known as diaphragm pumps, are widely used across South Africa and Africa for handling challenging fluids in industrial, mining, chemical, and agricultural applications. As a result, these AODD 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 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, as well as discharge cycles that transfer liquid efficiently.

Unlike centrifugal pumps, AODD pumps do not rely on high-speed rotation. Therefore, they can handle a wide range of fluids, including those that are thick, abrasive, or sensitive to shear.

AODD pumps are also 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, as well as their durability.

Handles a wide range of fluids

Suitable for clean liquids, sludge, slurry, chemicals, as well as viscous materials.

Self-priming capability

Can run dry without damage and also 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 of AODD pumps:

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., aluminum, stainless steel, plastic) must match the fluid.

Operating environment

Temperature, pressure, as well as 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 also slurry transfer
• Chemical processing and also handling
• Wastewater and effluent systems
• Food as well as beverage processing
• Paints, coatings, as well as adhesives
• Agriculture and fertilizer transfer

Across Africa, these pumps are particularly valuable in environments where durability, as well as flexibility are essential.

Types of AODD Pumps

Different applications require different configurations and materials.

Metallic Diaphragm Pumps

• Made from aluminum, 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. You can also check what size you need with our borehole calculators and our solar pump calculators.
