Decoding the Working Principle Of Air Operated Diaphragm Pump

Seeking a dependable and robust industrial fluid transfer solution? The air-operated diaphragm pump is a versatile, positive-displacement pump used to efficiently move a wide variety of liquids, from corrosive chemicals to viscous liquids. It is a versatile machine used for food, chemicals, and mining industries, among others. You will be able to understand the fluid transferring machine better if you know how it functions. In this post, we will go through step-by-step details on how this machine functions.

Understanding Air-Operated Diaphragm Pump

Before diving into the working principle of the air-operated diaphragm pump, let us understand this machine. The machine runs on compressed air. It consists of two flexible diaphragms that move back and forth, creating a suction and leading to the discharge of fluid effectively.

Step-by-Step Guide to the Functioning Of Air-operated Diaphragm Pump

Step 1: Compressed Air is Introduced

Once the machine is started, the compressed air is introduced, which is the driving force behind all the internal motion. The process starts by entering the central air valve. The air is then directed into the air chamber behind the diaphragm. The air creates a pressure, which forces the diaphragm to move forward. This movement leads to the movement of the fluid as well. At the same time, the other diaphragm is pulled back because it is connected by a rod. It leads to the creation of a back-and-forth movement. The air valve also moves back and forth automatically. It ultimately allows the cycle to continue.

Step 2: One Diaphragm Pulls back and creates Suction

The backward motion of the diaphragm increases the volume inside the chamber and lowers its internal pressure. Due to the difference in pressure, the fluid is drawn from the suction line. The check valve at the suction side opens up automatically and allows the fluid to flow through. The discharge check on the other side is closed so that the fluid does not flow back and continues moving forward.

Step 3: Opposite Diaphragm Pushes Discharge Fluid:

While the suction of the fluid takes place on one side, the other diaphragm is pushed towards the compressed air. It decreases the movement of the volume in the chamber, increasing the pressure. At this point, the diaphragm is moving with full force, which leads the fluid to move forward smoothly. It ensures a maximum amount of fluid to displayed per cycle. This action is highly efficient and leads to proper discharge at a consistent rate.

Step 4: Exhaust Air is Released to Reset the Stroke:

Once the discharge stroke is completed, the air is vented in again, which allows the diaphragm to go back into its original position. The air valve assembly shifts the air flow to the opposite chamber while releasing the spent air. The diaphragm, which has just discharged the fluid, will be pulled back, connecting the shaft. The venting process prevents pressure build-up and allows the smooth flow of the fluid.

Step 5: Reptation:

The strength of the machine lies in its consistency, which leads to smooth operations. The air valve switches the direction after venting out the air and sending the compressed air in the opposite direction. It ends up leading to the alternative roles of the diaphragm. One pulls in the fluid while the other pushes it out. It creates a rhythm of continuous liquid flow movement. It makes the AODD pump apt for on-site and continuous use scenarios.

Benefits & Operational Tips Of Air Operated Diaphragm Pump

Here are some of the benefits as well as the operational considerations of the liquid managing pump.

These pumps are dry without causing damage to any internal components.

The self-priming property of the machine allows it to lift the fluid to several feet even when it is dry.

The ergonomous design allows handling slurries, solids, and harsh chemicals.

It does not consist of mechanical seals, which means less to no maintenance is needed.

The body is made with sturdy metal, like stainless steel, which allows compatibility with harsh chemicals.

Final Words…

It will not be wrong to say that the air-operated pump for handling fluids is the most practical and versatile pump available. The simple and robust construction allows reliability even in heavy-duty industrial operations. The above-mentioned steps would have hopefully helped you understand how the air-operated diaphragm pump works.
