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 .

Solutions to Prevent Oil Backstreaming in High Vacuum .

Nov 05, 2014 · Oil backstreaming can occur in the event of a power outage when oil from the rotary vane pump backs up through the forelines into the vacuum chamber of the turbo pump. In some applications, minor backstreaming has no impact; in others, where the purity of materials is critical, backstreaming cannot be tolerated.

Vacuum Pump Filter: The Ultimate FAQ Guide | Filson Filter

A vacuum pump will release visible oil mist and smoke into the air. But fitting an oil mist eliminator will remove 99.9 percent of the smoke and oil mist from the exhaust fumes of the vacuum pump. This will inhibit buildup of oil in the ambient air that could as in turn lead to health hazards.

Vacuum Pump Oil: The "Circulatory System" of the Vacuum .

Jun 14, 2016 · Just as vacuum pumps can be considered the heart of the vacuum furnace, so too can the oil be thought of as its circulatory system. The selection and properties of the oil are critical to proper furnace operation. Pump oil serves different purposes in different types of pumps, and even has different functions within the same pump. In addition to lubrication, it helps provide the seal on rotary .

CF-0118-102 - Vacuum Pump Inlet Filters | Parker NA

Ideal for prevention of oil backstreaming & removal of high concentrations of solids View Series Page. . Vacuum Pump Inlet Filters prevent oil back streaming from the pump to the evacuated chamber and protect the pump from damage by submicron particles. These filters increase productivity and eliminate costly maintenance.

Maintenance and Troubleshooting of Oil Diffusion Pumps

Oil diffusion pumps are still a widely used type of high vacuum pump. This is because they are relatively inexpensive, highly reliable, and very durable. Yet . a small amount of backstreaming, movement of oil molecules into the vacuum chamber, occurs. In . if there is diffusion pump oil loss, log the amount. This loss of fluid can be caused by:

Elimination of backstreaming from mechanical vacuum pumps .

Mechanical vacuum pumps used to obtain pressures near or below 0.1 Pa (∼0.75 mTorr) contain oil for sealing, lubrication, and cooling of internal moving parts. The presence of this fluid at the inlet of the pump provides the possibility of backstreaming and contamination of the vacuum system.

Used for light gases, they produce low noise with minimal oil backstreaming, and have a long operating life. These Alcatel Adixen 2005SD 2005 SD vacuum pumps have a pumping speed displacement of 3.8 CFM. This Alcatel Adixen 2005SD 2005 SD dual stage rotary vane vacuum pump is Brand New and comes with manufacture warranty.

Backstreaming - Vacuum Furnace Engineering, Manufacturers .

Jan 08, 2013 · In simplest terms, backstreaming is the movement of pumping fluid back into the vacuum furnace chamber, that is, oil vapor molecules attempt to reverse course and move up and back toward the vacuum vessel, opposite to the direction of the desired gas flow.

Backstreaming Traps for Oil-Sealed Pumps | Normandale .

When the analysis of a vacuum process indicates that the possibility of oil backstreaming from an oil-sealed mechanical pump is a potential process killer, the .

Diffusion Pumps & Backstreaming: What, Why and How to .

Jul 27, 2017 · The pumping system is designed to pump in a certain direction. Backstreaming occurs when the pumping fluid flows opposite of that desired direction. This results in the pumping fluid entering the vacuum furnace chamber rather than going in the desired direction of flow back into the base of the pump where it is recirculated.
