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

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.

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 .

Working Flow Rate: How to Compare Vacuum Pumps .

Working Flow Rate: How to Compare Vacuum Pumps .

May 20, 2013 · Every pump has a measurable working flow rate at every point in between atmospheric pressure (the specified flow rate) and the pump's ultimate vacuum (zero flow). To present working flow rates concisely across several orders of magnitude of vacuum pressures, those flow rates are often charted as a performance curve on a log–log scale.

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.
