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 .

Rotary Pumps - an overview | ScienceDirect Topics

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.

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.

The Fundamentals of Vacuum Theory

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.

Regenerative Blowers - Becker Pumps Corporation

They are also used in lifting, packaging, and conveying products. A regenerative blower can be used to remove dust or smoke from the air, extract soil vapor, or perform sewage aeration. They are well-suited for applications that require high rates of air flow at a low pressure, or when a vacuum .

Solutions to Common Centrifugal Pump Problems | Pumps .

Low head (flow too high)— A low-head condition indicates too much flow, and the flow is likely not going where it should. System leaks can be internal or external. A diverter valve that allows too much flow to bypass or a failed check valve that lets flow circulate backward through a parallel pump would result in too much flow and low head.

Vacuum Check Valves | Vaccon Vacuum Products

The large unrestricted flow path ensures high flow at low vacuum levels. The low cracking pressure allows the vacuum system to reach its maximum vacuum level .

Types of flow

In vacuum systems, the pipes are dimensioned in such a manner that turbulent flow occurs only briefly at relatively high pressures, as the high flow resistance that occurs in this process necessitates that the pumps used produce higher volume flow rates. Knudsen flow in medium vacuum. If the Knudsen number is between 0.01 and 0.5, this is .

pressure. It has difficulty pumping under high vacuum conditions as can be seen in Fig. 1. It begins to lose pumping speed below 1 Torr where the Turbo-molecular pump can begin to take over. For this reason, the two are used in conjunction to pump a chamber down from atmospheric pressure to low vacuum (the RVP) and from low vacuum to high .
