Anyone without a thorough grasp of pumps may believe that vacuum creation is as simple as “plugging in a pump,” turning it on, and waiting for the vacuum to drop to the desired level. However, the truth is that there is a lot more to the process.
Vacuum pumps like LeDab Vacuum pumps are used to create a vacuum by removing air or gas molecules from a sealed volume. A process gas at a certain pressure, for example, can be used to manage the vacuum level.
Finding the proper vacuum pump necessitates a thorough grasp of not just the required vacuum level and application but also the process conditions, operating range, and benefits and limits of each vacuum pump type.
We’ll go through the four things to consider when deciding between different types of vacuum pumps in this blog.
- LEVEL OF VACUUM
The pump you choose is primarily determined by the amount of suction you require. In vacuum technology, the different pressure ranges are typically defined as follows:
The vacuum is rough (from 10 3 mbar to 1 mbar)
Vacuum level: medium (1 mbar to 10 -3 mbar)
Vacuum is high (10 -3 mbar to 10 -7 mbar)
Vacuum at extreme levels (10 -7 mbar to 10 -12 mbar)
Extremely high vacuum levels (less than 10 -12 mbar)
It’s also worth considering whether the goal is primarily to pump down to the appropriate pressure level or maintain a specific pressure level. At the same time, sure gas loads are added to the vacuum system (e.g. for process reasons). While some vacuum pumps are better suited to pump-down processes (but may struggle with high process gas loads), others are better suited to high gas gears.
- THE PROCESS’ IMPACT ON THE PUMP
The pump(s) chosen will vary depending on the application area and medium to be pumped. Rotary vane (RV) pumps, for example, are well suited for a variety of low and medium vacuum applications, such as research and development, analytical instruments, industrial and coating activities, freeze-drying, process engineering, and so on.
- MAINTENANCE AND INVESTMENT
Initial capital expenditures, operational costs, and maintenance requirements should all be considered, in addition to what has to be accomplished.
Using two high-vacuum pump technologies as examples, turbomolecular pumps (TMP) and oil diffusion pumps, it is fair to say that the initial expenses for TMP are often far more significant than those for an oil diffusion pump. Oil diffusion pumps, on the other hand, may cost more over five years due to more incredible energy and maintenance expenditures. Eco-friendly items are available for various products.
