Principles of an AODD Pump: How It Works and Why You Need One

AODD (Air Operated Double Diaphragm) pump is an important equipment in many industries, as no electricity is required to operate it. This positive displacement pump features two flexible diaphragms that operate in alternate directions and create suction and discharge pressure. The unique working principles of an AODD pump make it suitable for businesses that deal with a variety of fluids, from corrosive to abrasive. 

In harsh working conditions, like no availability of electricity, an AODD pumps can be useful as it moves liquids using compressed air. Continue reading this blog and learn more about the principles of an AODD pump, its key features, and where they are commonly used. Also, it will explain why having an AODD pump is a must for businesses, particularly those operating in wastewater treatment, chemicals, food processing, etc. 

Key Features of AODD Pump

Among all the pumps that are used to move various fluids, from thick fluids to chemicals, AODD pumps stand out. They are popular for their unique and simple design, which guarantees reliable performance. Here are the key features of compressed-air-driven pumps that make them suitable for harsh environments:

1. Self-Priming- This pump is highly reliable for applications with unpredictable fluid supply or fluid source above it. Without filling the pump chamber with fluid, you can utilize it. 

2. Run-Dry Capability- Unlike other pumps, in which liquid supply is essential, this pump can operate without liquid in the system without damage for a long time.

3. Versatile Fluid Handling- Besides their ability to run dry, these pumps are designed to handle various fluids, from fluids with solid and abrasive materials to thick fluids and chemicals.

4. No Electric Drive Required- They are powered by compressed air, which makes them portable and easy to use in situations where an electric supply is not available. Also, in hazardous applications where a small electric spark can cause an explosion, these are highly useful.

5. Simple Maintenance- Their design is very simple with very few movable parts, so they are easy to maintain and have a long lifespan.

6. Adjustable Flow Rate- By controlling the compressed air supply, these pumps provide a precise fluid flow rate, from zero to maximum flow.

7. Sealless Design: Unlike other pumps, they do not require costly mechanical seals or packing, which makes them a cost-effective option.

8. Bolted Construction- The time spent on assembling and disassembling the pump is reduced with its bolted design.

Principles of an AODD Pump: How They Work

The working principles of an AODD pump are based on alternate compressed air movement, which creates pumping action. Here’s a brief explanation of how they work:

• Firstly, the compressed air enters the pump and moves to one side of the air chambers or diaphragms.
• The air pressure pushes the diaphragm, making it move. This movement is linked to a shaft, which moves the other diaphragm in the opposite direction.
• As the diaphragm on one side moves, the vacuum created in the fluid chamber pulls fluid from the inlet valve. At the same time, the other diaphragm pushes fluids out through the outlet valve.
• This process is reversed, and the pumping cycle is continued, as the compressed air moves to the opposite side of the pump.
• Generally, the ball-shaped check valves make sure the right direction of fluid flow inside the pump. The alternating movement of the diaphragm with the help of compressed air creates a continuous pumping action.

Applications of AODD Pump

These pumps are used to transfer liquids with high-viscosity and abrasive or solid content, like corrosive chemicals and slurries. 

• Chemical Processing- In this industry, these pumps are used to transfer harmful and corrosive chemicals safely.

• Mining- They are also used for dewatering trenching sites, pumping mud and slurry, and handling rough or abrasive materials.

• Water and Wastewater Treatment- In this industry, these pumps handle the movement of sludge, wastewater, and fluids with solid content.

• Oil and Gas- They are used to transfer various fluids, such as drilling mud, flammable liquids, crude oil, and others. 

• Other Industries- They also play significant roles in other industries, like food, pharma, and manufacturing.

Why You Need an AODD Pump

If you own a business in which you frequently deal with dangerous, sticky, and thick fluids, AODD pumps can be a great choice. Here are some reasons that make an AODD pump a smart investment:

• Safe to Use: They can work without electricity, which eliminates the risk of explosions and other hazards due to electric sparks. Also, their simple and sealless design, featuring flexible diaphragms, reduces the risk of leaks. 

• Cost-Effective: Compared to other positive displacement pumps, they are less costly, and as they operate with compressed air, they help with cost savings on energy bills. 

• Low Maintenance: These pumps have few moving parts, a simple design, and no internal seals, which helps them deliver high performance over a long time with low maintenance.

• Versatility: They can handle various fluids, from thick and abrasive to stress-sensitive fluids, which eliminates the need to acquire multiple pumps.
