The ordinary vacuum pump was invented in 1650 by Otto von Guericke.

A vacuum pump is a pump that removes gas molecules from a sealed area in order to leave behind a partial vacuum.

Different pump types differ in details like sealing material, pressure, flow, manufacturing tolerances, tolerance to chemicals and dust and their tolerance to liquids and vibrations.

There are 3 main types of vacuum pumps:

• The positive placement pump
• The momentum transfer pump
• The Entrapment pump
