Vacuum pump - Wikipedia

A vacuum pump is a device that draws gas molecules from a sealed volume in order to leave behind a partial vacuum. The job of a vacuum pump is to generate a relative vacuum within a capacity. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity. Contents 1 History

How a Vacuum Pump Works - Arizona Pneumatic

This is often done by a mechanically moving part of the pump that often rotates, accelerating the molecules of the gas and making the region of low pressure. When the level of vacuum is reached the tank is isolated by a high vacuum valve. Any exchange of gas between the container and the pump is stopped by the valve.
