Vacuum pumps are integral to many industrial processes such as hydrogen extraction, glass and foil coating, drying, and bottling. They move gas or air molecules from a high to low-pressure sealed space, creating, improving, and maintaining a vacuum state.
A vacuum is a space devoid of all matter with gaseous pressure lower than atmospheric pressure. A vacuum pump moves gas molecules and air matter from one contained area to the next, creating a full or partial vacuum by altering these high-pressure and low-pressure states.
Vacuums exist within varying vacuum ranges. These are:
Primary pumps work in rough/low vacuum ranges, booster pumps in low to medium vacuum ranges, and secondary pumps in high to ultra-high vacuum ranges.
You can also opt for a dry vacuum pump or wet vacuum pump. As the name suggests, dry vacuum pumps don’t require water or oil to operate.

Some applications of vacuum pumps include:
A manual water pump is an excellent example of a positive displacement pump. These dry pumps operate by pushing fluid from the vacuum chamber into the pump's small cavity, creating a small sealed cavity. Positive displacement pumps then open up the pump's cavity to the atmosphere and squeeze it back into a small size.
These high-performance, compact, and affordable wet vacuum pumps are ideal for low/rough vacuum settings and in processes that use high boiling solvents and aqueous samples.
These pumps are chemical- and corrosion-resistant, which means they are compatible with a wide range of acidic, viscous, and corrosive products.
Liquid ring vacuum pumps form a liquid ring on the pump walls with centrifugal force. These wet pumps are useful in distilleries, sugar factories, and petroleum refineries.
A scroll pump uses dry and clean vacuum pumping, ideal in laboratories and other medical applications.
Turbomolecular vacuum pumps use high-speed rotating blades that function in a higher vacuum pressure range. Every pump rotation adds kinetic energy, resulting in a further pressure increase along the pump's side channel, perfect for lab analysis of gas molecules or analytical instrumentation and tools applications.
These pumps function at lower flow rates than transfer pumps but provide extremely high oil-free vacuums as they have no moving parts with an ideal compression ratio due to reduced pressure at the inlet. Also known as capture pumps, they use ionic reactions, cryogenic condensation, or chemical reactions to create the vacuum.
Vacuum pumps are integral to cleaning and sealing a contained space during industrial and high technology processes.
When you search for a vacuum pump system, consider the intended use, the pressure ranges it will operate in, and the type of vacuum pumping (wet or dry). You should also consider the overall cost, including purchase price and maintenance/operating costs.
