Different Types Of Vacuum Pumps And Systems

Vacuum pumps and systems are necessary for maintaining the proper level of pressure in a system. They are used in countless applications in many different environments, from the home to large industrial complexes. Because liquids cannot be pulled, suction cannot be used to create a vacuum. Therefore it becomes necessary to create an artificial vacuum, and the easiest way that this can be accomplished is by expanding the air that is in a container. In order to evacuate a chamber constantly, these machines contain a compartment that is always being closed off, emptied, and them expanded once again. This is the principle by which these machines work.

Busch vacuum pumps and systems are now available in many different shapes and sizes. You will find that they operate on the same basic principles, but the larger ones for industrial needs are much more complex. The following is a brief list of the different types that have been developed so far:


Rotary vane by far the most commonly usedDiaphragm no contamination from oilLiquid ringPiston the lowest priceScroll features the highest speed for a dry pumpExternal VaneRoots Blower also known as a booster; it has a high pumping rate, but low compressionMultistage roots uses several stages to produce both high speeds and compression

Kinney vacuum pumps and systems also make use of several different types of techniques in order to achieve their purpose. Often times this involves the use of multiple chambers, pumps, and procedures. For example, positive displacement pumps can create only small vacuums due to mechanical limitations. These stronger vacuums must be created using a more complex series of stages typically starting out with a fast pump down. There are many different types of combinations that can be used in order to achieve the desired results.

So, now that you understand a bit more about how these Edwards vacuum pumps and systems work, it is time to discuss a few of the situations where they can be used. There are many different industries and uses for these machines, including, but not limited to the following: composite plastic molding, flight instruments in aircraft, the production of electric lamps and CRTs, processing of semiconductors, electron microscopy, vacuum coating, freeze drying, trash compacting, sewage treatment, and many more.

This article contains only a few examples of the many different options you have when it comes to vacuum pumps and systems. When looking for the right one for your application, it is a good idea to use the type of product that is recommended by the manufacturer or your equipment. While there are companies that deal in these products all over the world, you will get the best service when you choose someone close to you.
