Removing all molecules from a space and evacuate the entire air or gas in the basics of a vacuum pump. However, the molecules will never move if there is no difference between certain two regions. The region with a smaller number of molecules will form the low-pressure region and the region with higher numbers of the molecule will be the high-pressure region. Eventually, an engine which is capable of creating different pressure between certain regions and creates a vacuum is called a vacuum pump.

There are two basic types of pumps, one is the transfer pump and the other is the trapping pump. The first type of pump i.e. the transfer pump also known as kinetic pump while pushing the gas or air transfers the gas from the inlet to the outlet. This is done by a mechanically rotating part of the pump which eventually accelerates the gas molecules in order to create low pressure in the region. The high level of vacuum is then regulated by vacuum valve. The vacuum valve stops the exchange of gas between the pump and container.
The trapping pump also known as the capture pump is placed in the container which supposed to be evacuated. The pump evacuates the molecules through condensation or sorption on the surface of the internal portion of the container. As the gas molecules come across the surface which is refrigerated, the gas eventually gets evacuated in the form of liquid.
There are other popular forms of understanding the types of vacuum pumps. Accordingly, there are three basic types of vacuum pumps, one is the positive displacement pumps which use a specific mechanism of expanding the cavity repeatedly and allow the gas to get into the cavity from the chamber, then seal the cavity and exhaust it. The second type of pump is the momentum transfer pump which is also known as the molecular pump. In this type of pump, high speed rotating blades are used to remove the molecules out of the chamber. The third is the entrapment pumps which capture the gas in the form of solid state. This type includes getters, cryopumps and ion pumps.
Positive displacement pumps have the most common configuration to get a high level of vacuum. However, whichever the types of vacuum pump you may prefer, they require regular maintenance and repair to serve your purpose on a long term basis.
