In general, pumps are devices typically used to move liquids, fluids, and gases by creating pressure through mechanical movements. They can be classified into two types, namely dynamic and positive displacement pumps, and both can be further divided into other subcategories. Under the positive displacement type lies one of the most commonly used pumps in different industries: diaphragm pumps.

What Is a Diaphragm Pump?
A diaphragm pump is among the most prevalent pneumatic instruments in different industries. One reason for its popularity is its versatility. It is commonly used to siphon and release almost any kind of liquid, so it is perfect for high-viscosity solutions, such as oils and resin blends. Additionally, it’s ideal for pumping concrete mixes, strong acids, and other fluids that are either too abrasive or have a lot of solid content.
What you should remember about diaphragm pumps is they’re self-priming devices. When running at full speed for a long period, pumps would typically overheat and get damaged. This happens because air enters the machine and gets mixed with the fluids inside. With a diaphragm pump, this is not a problem because the self-priming feature helps displace excess air, allowing the equipment to work more efficiently, even for many hours on end.
How Do Diaphragm Pumps Work?
The working principle behind diaphragm pumps can be pretty tricky. It’s a complex machine with many components that move alternately, but the most important parts are the diaphragms located side-by-side inside the machine. When the right diaphragm contracts, the left one expands. This alternate motion is the key to the efficiency of the device.
Every time one of the diaphragms tightens on one side, fluids will be sucked into that part of the equipment. Once it expands again, the substance will be ejected from the machine.
The same thing happens on the other side of the pump, but in an alternate way. So, every time the right diaphragm expands to eject what it siphoned, the left side of the machine is already contracting and sucking in fluids, too.
What Are the Different Kinds of Diaphragm Pumps?
If your company requires the use of diaphragm pumps, there are many options for you to choose from. Here are some of the available types you can check out:
• Air Operated Diaphragm Pump – This is the most common kind of diaphragm pump. It uses compressed air to siphon and release the fluids. If you use this kind of pump, be sure to check if the air pressure inside the machine still meets the acceptable level. This prevents accidents and ensures the equipment will not malfunction and cause any major issues.
• Motor-Driven Pump – If you want a lighter option, motor-driven pumps might be right for you. There are small motor-driven pumps available, and they typically produce between 60 to 100 psi. Since this type heavily relies on electricity, overheating is one of its main issues. Be sure to check it regularly when it’s in operation to avoid this problem.
There are at least three kinds of diaphragm pumps, but air operated ones are the most commonly used across different industries. Air operated diaphragm pumps are available here at Compresstech Resources, Inc. Feel free to get in touch with our team today if you wish to buy a unit from us.
What Are Air Operated Diaphragm Pumps?
They are sometimes called air operated double-diaphragm (AODD) pumps because of their inner mechanisms. Inside the machine, there are two chambers, one beside the other. Each of them has a corresponding diaphragm that moves alternately when the equipment is switched on.
AODD pumps are pretty versatile, and they offer a lot of benefits, such as:
• Leak-Free Features – Pumps used to move liquids typically suffer from leaks, but this isn’t a problem with air operated diaphragm pumps in the Philippines. They are specially designed with stationary seals that prevent the fluids from seeping outside the machine.
• High Wear Resistance – Other types of pumps malfunction after some time, especially when they are left working for hours on end. The machine can sometimes overheat or some of the components end up breaking because of excess friction and pressure that cause them to deteriorate. This happens with AODD pumps, too, but at a much slower rate. These devices have pressure-balancing technology that helps prevent damage.
• Gentle Pumping Action – What makes air operated diaphragm pumps a great choice is that they are more softly compared to other options. Because of their gentle pumping motions, they are the most suitable devices to use for shear sensitive liquids that change viscosity due to vibrations. Examples of these materials include creams and polymers, along with some pharmaceutical slurries and edible substances.
• Mufflers – Like any other pneumatic machine, AODD pumps make quite a lot of noise when they are in operation. The vibrations produced by the equipment when it runs can generate a lot of sound, but the good thing is there are ways to prevent that. You can put mufflers on the device if you don’t want to hear anything when it’s switched on.
