Some Interesting Facts About The Double Diaphragm Pump

By David Phillips


One of the most important pieces of equipment for managing huge amounts of liquid would be the pump. Now, if one is transferring a lot of liquid of various types such as chemicals, solvents, and so on, then he or she will need what is known as a double diaphragm pump. This sort of pump is a very reliable and efficient pump with a robust built able to take those liquids.

Now, in order to know more about the pump, one has to first understand how it works. As the name implies, there are two diaphragms attached to the pump that would move pressure back and forth forming some sort of chamber. So what this pump does is that it brings in and brings out the fluids and air from the pump in one swift and single move.

Just to get an idea, the two diaphragms are connected by a big shaft with an air valve in the center of it. The air valve is the device that will determine where the air would move in the whole pump. The air valve regulates the cycle ensuring that the overall movement of the pump would only be in two strokes wherein the first diaphragm pushes liquid out and the second one takes it in through a suction.

While this is happening, the air of the second diaphragm is transferred to the first one creating air pressure. This would allow the liquid to follow and then be stored into the liquid chamber. Once this stroke is done, then the pump will prepare for the second stroke.

In the second stroke, the two diaphragms will then switch function. The first one will switch to the function of pumping in the fluid and the second one will be forcing out the fluids instead of the other way around. While that is happening, the direction of the air pressure switches as well. So when the pump is in motion, it will go though both the first and the second stroke first before it repeats the cycle.

Now, one may be wondering why these pumps are ideal for fluids. After all, there are so many different kinds of pumps in the market. The answer would lie in its overall efficiency and its versatility.

As mentioned above, these pumps are really good for chemicals and solvents. Aside from these two types of liquids, they are also good for thick and sticky liquids such as dirty water, gel, oil, cream, and liquidized foods. Lastly, they are also useful for pumping and filtering out some small solid materials that can usually be found in dirty water.

Those in he fields of engineering or other fields that deal with liquids must familiarize themselves with this piece of equipment. It just happens to be one of the most effective and efficient pumps to be used. It is robust, tireless, and very strong as a whole, which is why a lot of people who deal with liquids would use it. This is true especially for the industries that deal with sticky and strong fluids.
