How to select lab vacuum pumps for high vapor-flow .

Apr 27, 2017 · Depending on the design of a vacuum pump, the vacuum loss may be as little as 3-4 Torr, or as much as 12 Torr, with a corresponding loss of pumping speed near the ultimate vacuum. The difference may be enough to compromise your ability to reach the vapor pressure of the solvent you are evaporating, thereby dramatically slowing your process.

Vacuum pump - Wikipedia

Vacuum pump - Wikipedia

History Early pumps. The predecessor to the vacuum pump was the suction pump. Dual-action suction pumps were found in the city of Pompeii. 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. The suction pump later appeared in medieval Europe from .

Aug 10, 2018 · As a result they can generate a high throughput and provide a quick drawdown in the roughing and low vacuum phases. Pumps used to create high and ultra-high vacuum include diffusion pumps, cryogenic pumps, and ion pumps and must operate in the molecular flow range. They therefore use different technology than roughing and low-vacuum pumps.

However, when these services involve high capacities and low-viscosity fluids, vertical centrifugal pumps are usually used. • Vacuum services. Rotary pumps, lubricated by special oils, are often used in vacuum services to pump air or other gases and vapors. Low vapor pressure oils are used to lubricate the pumps and seal the clearance spaces.

Understanding Vacuum and Vacuum Measurement

Understanding Vacuum and Vacuum Measurement

Low Vacuum – also called rough vacuum, is a vacuum that can be achieved or measured by basic equipment such as a vacuum cleaner. Medium Vacuum – is a vacuum that is typically achieved by a single pump, but the pressure is too low to measure with a mechanical manometer.
