Pumps
A vacuum pump is a device that draws gas molecules from a sealed volume in order to leave behind a partial vacuum. The job of a vacuum pump is to generate a relative vacuum within a capacity. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity.

These include both oil-less/dry and oil flooded rotary vane; oil-less/dry rotary screw; regenerative blowers, and radial blowers.

But the reality is that there is far more to the process.
The vacuum level can be controlled, for example, with a process gas at a specific pressure.
In the field of oil regeneration and re-refining, vacuum pumps create a low vacuum for oil dehydration and a high vacuum for oil purification.
Vane, Claw, Piston and Lobed operating designs.
Vacuum pumps are used to remove air or gas molecules from a sealed volume thus creating a vacuum.
Oil, Dry and liquid ring vacuum pumps
It also requires an understanding of process conditions, the operating range and the benefits and limitations of each specific vacuum pump type.
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 ion implantation, dry etch and PVD, ALD, PECVD and CVD deposition and so on in photolithography, electron microscopy, medical processes that require suction, uranium enrichment, medical applications such as radiotherapy, radiosurgery and radiopharmacy, analytical instrumentation to analyse gas, liquid, solid, surface and bio materials, mass spectrometers to create a high vacuum between the ion source and the detector, vacuum coating on glass, metal and plastics for decoration, for durability and for energy saving, such as low-emissivity glass, hard coating for engine components (as in Formula One), ophthalmic coating, milking machines and other equipment in dairy sheds, vacuum impregnation of porous products such as wood or electric motor windings, air conditioning service (removing all contaminants from the system before charging with refrigerant), trash compactor, vacuum engineering, sewage systems (see EN1091:1997 standards), freeze drying, and fusion research.
Finding the right vacuum pump requires a good understanding of the necessary vacuum level and application.
Anyone without a deep understanding or knowledge of pumps might think that vacuum generation is simply a question of “plugging in a pump”, starting it up and waiting for the vacuum to drop to the required level.
High Vac Depot offers a variety of industrial vacuum pump types that cover a wide range of operating pressures from atmospheric to 0.5 torr (29.9 in.Hg).
Special University and Government discounts available.
Especially in the field of transformer maintenance, vacuum pumps play an essential role in transformer oil purification plants which are used to extend the lifetime of transformers in the field.
