| Vacuum pumps are used to pump gases out | | | | piston, and rotary vane pumps can go up |

| The vacuum pump was invented by the | | | | plastic-sealed piston pumps, venture |
| German named Otto von Guericke.The flow | | | | vacuum pump, and scroll pumps are also |
| of air removal, the amount of vacuum | | | | used.Many industrial and scientific |
| produced, and the power that is required | | | | processes require vacuum-pump |
| to produce the vacuum are the main | | | | applications such as for the production |
| factors that go into choosing particular | | | | of electric lamps, vacuum tubes, |
| vacuum pumps. It is mandatory for | | | | semiconductor processes, lectron |
| manufacturers to provide information on | | | | microscopy, and medical processes |
| the flow-rating availability. Standard | | | | involving suction. Aerospace |
| measurements are in place to quantify | | | | applications include the use of vacuum |
| how much vacuum a pump produces. This is | | | | source to power gyroscopes in the |
| called mmHg or HG. A lower vacuum | | | | various flight instruments.In the case |
| provides high-flow pumps and a higher | | | | of a complete electrical failure, |
| vacuum provides low-flow ones.Vacuum | | | | special instruments in the instrument |
| pumps have much lower power requirements | | | | panel powered by the vacuum source are |
| than air compressors. Large-sized vacuum | | | | used. Standard features include |
| pumps are meant for continuous pumping. | | | | high-vacuum electric motor shutdown, |
| However, smaller pumps have high | | | | clutch-driven high-pressure pump, |
| efficiency; the only difficulty, | | | | trigger gun control, automatic |
| however, is that they get overheated | | | | waste-water pump-out, low-water shut |
| easily if used continuously. A single | | | | down, pressure-relief valve, waste |
| mechanism or a series of mechanisms or | | | | collection bag filter, emergency stop |
| parallel mechanisms are employed to | | | | button, hour meter and warranty for one |
