WebA vacuum pump is a device that extracts air or gas from a tank to create a partial or complete vacuum in the system in question. The air is sucked in by a gradual decrease in pressure in the confined space. The aspirated gaseous molecules are then released into the ambient air or another tank. WebIt plays a part when venting and evacuating a vacuum vessel and where there are leaks. Gas will always flow where there is a difference in pressure. Δp = (p 1 – p 2) > 0. The intensity of the gas flow, i.e. the quantity of gas flowing over a period of time, rises with the pressure differential.
