A vacuum pump is a pump system that eliminates molecules of gas from a sealed volume to left over a partial vacuum. The first vacuum pump was developed by Otto von Guericke in 1650 and was preceded by the suction pump, which was invented in ancient time.
These pumps are merged with operational procedures and chambers, into a wide-ranging variety of system. Occasionally, more than one pump to be utilized (in parallel or series) in a single application. A rough vacuum or partial vacuum can be made by using a positive displacement pump that delivers the gas load from an inlet port to an outlet or exhaust port. Due to their mechanical limitations, these pumps are able to attain only a low vacuum. For achieving the high vacuum, other techniques must be used, usually in series (typically following an initial fast pump down along with a positive displacement pump. Some cases might be the use of an oil-sealed rotary vane pump (which is the most common positive displacement pump) assists a dry scroll pump or a diffusion pump supporting a turbo-molecular pump. The more combinations can be done depending upon the level of the vacuum to be required.
A rotary vane pump is a positive displacement pump that consists of vanes mounted to a rotor, which rotates within a hole. In certain cases, these vanes may have flexible length and to be stretched to continue contact with the walls as the pump rotates. The vane pump was introduced by Charles C. Barnes of Sackville, New Brunswick, and patented in June 1874. There have been multiple enhancements, such as a variable vane pump for gases.
The rapid growth of the semiconductor and electronics industry can be attributed to growing proliferation of consumer electronics such as smartphones, laptops and other relevant gadgets. This is one of the major aspect driving growth of the rotary vane pump market. Increasing demand for these pumps among the food processing industry is another aspect supporting the revenue growth of the market.

However, the low efficiency of these pumps and low degree of vacuum are some of the major aspects that are challenging growth of the global market.
The type of rotary vane pump can be divided into two categories: single stage rotary vane vacuum pumps and two stage rotary vane vacuum pumps. Single-stage rotary vane vacuum pumps exhaust into a built-in chamber within the pump which segregates oil from the pumped gas. Furthermore, the oil is reverted and the gas exhausted.
The application of rotary vane pumps includes semiconductor and electronics industry, chemical industry, laboratory research, food industry, and machinery industry. Rapidly growing food processing industry across the globe is fueling the demand for rotary vane pumps.
Growing demand for rotary vane vacuum pumps in Asia Pacific can be attributed to the rapidly growing food processing industry. North America is dominating the rotary vane vacuum pumps market. This can be attributed to the strong presence of the rotary vane vacuum pumps manufacturing companies in this region.
