function of vacuum pump

Vacuum pump - Wikipedia. A vacuum pump is a device which was invented in 1650 by Otto von Guericke. Its main function is to remove gas molecules from a sealed volume and leave a partial vacuum behind. Basically, it is used to pull out air and gases from a sealed or confined space due to which the space is left out of any gas and air molecules.
