Air Operated Diaphragm Pumps

Air operated diaphragm pumps (AODP) are a type of positive displacement pump that use compressed air as the power source to move fluid. They are often used in industrial and commercial applications for transferring fluids, such as water, oil, chemicals, and viscous materials.

The pump has two flexible diaphragms that are connected to a common shaft. Compressed air is directed into one side of the diaphragm, causing it to flex inward and push the fluid out of the pump chamber. The other diaphragm simultaneously flexes outward, drawing fluid into the opposite chamber. When the compressed air is redirected to the other side, the process is reversed and the diaphragms switch positions, creating a continuous flow of fluid.

One advantage of AODP is their ability to handle a wide range of viscosities and solids content, making them suitable for many different types of fluids. They also have a simple design, which makes them easy to maintain and repair. Additionally, AODP are typically self-priming, meaning they can start pumping without the need for manual priming.

However, AODP can be noisy and require a source of compressed air to operate, which can be costly. They also have a limited flow rate and are not suitable for high-pressure applications.

Tapflo AODD Powder Transfer Pumps

AODD (Air Operated Double Diaphragm) powder transfer pumps are a type of AODD pump specifically designed for the transfer of powders and dry bulk materials. These pumps use the same basic principles of AODD pumps but have additional features to prevent clogging and ensure efficient transfer of powders.

AODD powder transfer pumps typically have a wider flow path, larger diaphragms, and larger suction and discharge ports compared to standard AODD pumps. This design allows for the transfer of thicker and more viscous materials, such as powders and dry bulk solids. The pumps also have specialized diaphragms made of materials that are resistant to abrasion and wear from the particles in the material being pumped.

One of the main advantages of AODD powder transfer pumps is their ability to handle a wide range of powders and dry bulk materials, including those that are abrasive or have a tendency to clump or bridge. They are also able to handle fluids with varying viscosities, making them versatile in many industrial and commercial applications.

However, it is important to note that AODD powder transfer pumps have a limited flow rate and are not suitable for high-pressure applications. Additionally, they require a source of compressed air to operate, which can be costly.

Reduced contamination
