Air driven pumps are commonly used as an alternative
How does an air driven pump work? This type of air pump utilizes a part called the diaphragm, which is designed similarly to a human's. It is made of flexible materials such as rubber, Teflon or thermoplast and as the air enters the air cylinder, the piston inside the pump rises, pushing or lifting the diaphragm. This movement of the diaphragm causes another part called the check valve element (located at the input/ entry point), which is also lifted allowing the entry of liquid into the machine. The diaphragm is then lowered down by pressure (compressed air) and the check valve on the discharge or output side is opened, releasing the liquid.
If you are still torn between an air driven pump and an electric pump, you should read on to learn some interesting advantages of the former. The most obvious advantage of air driven pumps is that they do not generate heat (as a result of using electrical energy); that means you have a lower chance of experiencing explosion or other fire hazard. You can practically use it anywhere because you do not have to look for power outlets and you do not have to purchase external controls. Because these pumps do not consume electricity, they will not add up to your bills.
Even if an air driven pump is simply designed, it does not mean that it functions less efficiently compared to those motor-operated types. In fact, its versatility gives it an edge. For example, you can use this pump to handle almost any type of fluid, viscous or not, and the pump will adjust according to your needs. It is compact but at such a small frame, it packs a pressure that can reach up to 26, 500 psi and it can easily maintain any selected pressure. It is also made from similar materials as the conventional pumps so durability and strength are out of the question.
Air driven pumps are not only used by large industries and they are very expensive. However, manufacturers create these tools to help people with various tasks so they are available in different styles. You can purchase a pump a couple of dollars above a hundred, although this is usually considered a low end pump (minimum features). Others may reach up to a thousand dollars and these types are mostly used in industrial plants. Pumps differ on features so before buying one, you should know what are the important key features you should look for.
