A vacuum bell jar is placed on a base which is vented to a hose fitting, that can be connected via a hose to a vacuum pump.

They are typically used as a vacuum pump, but can also be used as a gas compressor.

US Patent 1,091,529, for liquid-ring vacuum pumps and compressors, was granted to Lewis H.

Around the same time, in Austria, Patent 69274 was granted to Siemens-Schuckertwerke for a similar liquid-ring vacuum pump.

Single-stage vacuum pumps typically produce vacuum to 35 Torr (mm Hg) or , and two-stage pumps can produce vacuum to 25 Torr, assuming air is being pumped and the ring-liquid is water at 15"nbsp;°C (60"nbsp;°F) or less.

In petroleum refining, vacuum distillation also makes use of liquid-ring vacuum pumps to provide the process vacuum.

Liquid-ring vacuum pumps can use any liquid compatible with the process, provided it has the appropriate vapor pressure properties, as the sealant liquid.

Since oil has a very low vapor pressure, oil-sealed liquid-ring vacuum pumps are typically air-cooled.

The ability to use any liquid allows the liquid-ring vacuum pump to be ideally suited for solvent (vapor) recovery.

Ionic liquids in liquid-ring vacuum pumps can lower the vacuum pressure from about 70 mbar to below 1 mbar.

A vacuum pump is used to remove the air out of a vacuum vessel for low-pressure experiments.

By filling the tube with other gases besides air, and partially evacuating it with a vacuum pump, Kundt was also able to calculate the speed of sound in different gases at different pressures.

Commercially available vacuum pumping systems can reach vacuum levels as low as .
