Vacuum Pumps

Metal Seals vs Elastomers

Elastomer seals are typically used in gas loads because they don’t require any compression to seal. However, the sealing performance depends on the pressure it takes to create a leak-tight seal. Metal seals are made by compressing the metal material to achieve a leak-tight seal at atmospheric pressures or less.

Extra Considerations For Ultra High Vacuum Systems

Vacuum systems have a variety of applications in industrial processes, including semiconductor processing and microelectronics manufacturing. Vacuum pumps are used for research in physics, chemistry, and biology. They are also used in the pharmaceutical industry and physical therapy. Here are extra critical considerations for ultra-high vacuum systems to help you make an informed decision about your purchase.

What Is Conductance And Why Does It Matter?

Any liquid will flow to fill any container with sufficient room. Fluids move everywhere, and things can’t stop them. The speed at which a liquid shifts from one container to another is often compared to the rate at which water would flow through a maze as if a go-through-the-maze or follow-the-trail game. This movement of fluid is measured by conductance — how easily the fluid forms and follows pathways through the maze.

Proper Cleaning of Vacuum Components

Clean surfaces are a must-have when dealing with a vacuum system and its accompanying technology. There’s a need to ensure that all impurities get removed from its surfaces. Their removal guarantees that they won’t desorb when exposed to vacuum conditions. If desorbed, they may accumulate on the vacuum pump or other similar components. In some cases, they could also produce gases that pollute the surrounding environment, making it difficult to breathe.

How To Select The Right Turbo Pump

Turbo pump selection is a critical decision for any vacuum process. The choice of the right vacuum pump will impact the performance and cost of your system. Choosing the wrong pump can lead to costly repairs, downtime, or even complete replacement of your entire system. This article discusses how you can make this important decision easier by following these ten steps.

Considerations When Leak Checking Your Vacuum System

A leak is a small opening in a system’s many or single components that permits gas to leave or enter uncontrollably. The pressure differential between the interior and outside of the system, as well as the gas type and hole size, determine the leak rate. Some of the factors that can cause system failure include contamination and outgassing. Leaks can affect the vacuum levels. Leaks in the pipes can stop vacuum systems from attaining the required vacuum level for the...

Proper Handling of Vacuum Components

Industrial vacuum pumps make one of the greatest man’s inventions (invented in 1650), contributing immensely to the modernization of industrial processes in engineering, machinery, and equipment. But what is a vacuum pump? An industrial air pump machine creates a vacuum by sucking air and gas molecules from sealed compartments or containers.

Suggestions For Ensuring The Highest Performance Of Your Vacuum System

Here are a few tips to make sure your vacuum system is performing optimally. A faulty vacuum system could cause a production halt. This system is made up of several components that must all work together to ensure that the system functions properly. Vacuum systems are only as good as you take care of them. It is important to know the factors that affect the performance of your vacuum system.

Which Roughing Pump Is Right For My Application?

A roughing pump is a vacuum pump used to evacuate a vacuum system to achieve a high vacuum or ultra-high vacuum. The term roughing-pump is gotten from the range it operates in, 0.1 Pa. There are two categories of roughing pumps, dry and oil-sealed roughing pumps. There are different types of designs you can pick from the two categories.

Virtual Leaks And Why They Matter

A virtual leak is a gas source that is trapped physically in a chamber. Therefore, the trapped gas pocket’s path that goes into the chamber proper becomes small and low conductance. Virtual leaks often occur due to lack of abiding by the correct vacuum practice or a manufacturing fault in the material. There are various types of virtual leaks. For instance, an internal weld crack. If there is air being released, the gas in the crack will leave the crack...
