Top 6 Things You May Not Know About Vacuum Pumps

1. The suction pump, a predecessor to the vacuum pump, was invented by the Arabic engineer Al-Jazari in 1206. It was not until the fifteenth century that the suction pump first appeared in Europe.

2. The first mercury barometer was invented by Evangelista Torricelli, based upon earlier work by Galileo, in 1643. The first sustained vacuum was achieved later the same year.

3. However, the first true vacuum pump wasn’t invented until 1654 by Otto von Guericke, who used it to evacuate the air between two hemispheres in order to demonstrate that they could not then be separated by two teams of horses (the famous “Magdeburg hemispheres experiment”).

4. In 1855, Heinrich Geissler invented the mercury displacement pump and used it to achieve an unprecedented vacuum of around 10 Pa (0.1 Torr).

5. Later that century, in 1874, a new style of pump consisting of vanes mounted to a rotor that turned within a cavity was patented by Charles C. Barnes of Sackville, New Brunswick, Canada. This type of pump became known as the rotary vacuum pump, and took depth of vacuum to a new level.

6. Dr. Wolfgang Gaede first reported the principle of the molecular drag pump at a 1911 meeting of the Physical Society in Karlsruhe. The pump was extremely well received and was considered to be the major event of the meeting. After many problems and setbacks, the first 14 pumps were ready for sale by the fall of 1912.
