Equipment generating a relative vacuum

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 suction pump, which dates to antiquity.[1]

The predecessor to the vacuum pump was the suction pump. Dual-action suction pumps were found in the city of Pompeii.[2] Arabic engineer Al-Jazari later described dual-action suction pumps as part of water-raising machines in the 13th century. He also said that a suction pump was used in siphons to discharge Greek fire.[3] The suction pump later appeared in medieval Europe from the 15th century.[3][4][5]
