A vacuum pump is a pump that sucks all of the air out of a space, leaving a vacuum behind. These pumps are used in a variety of industries all over the world. The most common place to see a vacuum pump is in an actual floor vacuum, designed to suck dirt out of carpet and other places. Vacuum pumps are also used in manufacturing, such as when creating vacuum-packed seals on products or by removing the air out of light bulbs or other devices to replace the air with gas. However, a vacuum pump manufacturer also creates vacuum pumps for many different uses- ones you may not be aware of. The following industries use vacuum pumps in day-to-day business.
