Vacuum pumps are used in many industrial and scientific processes, including: composite plastic moulding processes; production of most types of electric lamps, vacuum tubes, and CRTs where the device is either left evacuated or re-filled with a specific gas or gas mixture; semiconductor processing, notably … See more A vacuum pump is a type of pump device that draws gas particles from a sealed volume in order to leave behind a partial vacuum. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the … See more Early pumps The predecessor to the vacuum pump was the suction pump. Dual-action suction pumps were found … See more Pumping speed refers to the volume flow rate of a pump at its inlet, often measured in volume per unit of time. Momentum transfer and … See more Old vacuum-pump oils that were produced before circa 1980 often contain a mixture of several different dangerous polychlorinated biphenyls (PCBs), which are highly toxic, carcinogenic, persistent organic pollutants. See more Pumps can be broadly categorized according to three techniques: positive displacement, momentum transfer, and entrapment. Positive displacement pumps use a mechanism to repeatedly expand a cavity, allow gases to flow in from the chamber, seal off … See more Vacuum pumps are combined with chambers and operational procedures into a wide variety of vacuum systems.

A rotating shaft, in a sealed space, removes air and gas molecules. This action progressively decreases the air density within the enclosure resulting in a vacuum. As the pressure in the enclosure is reduced, it becomes more difficult to remove additional particles.
