How to Choose Between Different Vacuum Pumps?

There is a lot to understand about the vacuum pumps before putting them into use. One who does not know a lot about it will think that simply plugging in the pump can generate the vacuum and you just have to wait for the vacuum to drop to the needed level. But in reality, there is a lot more to the process. With the help of vacuum pumps, one can easily remove the air or gas molecules from the sealed volumes. 

Therefore, finding the right vacuum pump needs a lot of consideration and hence we are going to help you pick the right one.

Vacuum level

The pump you select depends on the level of vacuum you want to obtain. There are a few vacuum ranges that the machines operate on:

• Rough vacuum
• Medium vacuum
• High vacuum
• Ultra-high vacuum
• Extreme high vacuum

In the rough and medium vacuum segments, most of the gas molecules are present within the volume of the vacuum chamber. In the ultra-high and extreme high vacuum segments, most of the remaining molecules are present in the chamber walls. 

Impact of the process on the pump

The choice of the pump will vary based on the application area and the medium that needs to be pumped. The rotary vane pumps are mostly suited for the low and medium vacuum applications. Scroll pumps on the other hand can provide hydrocarbon-free vacuum experience by compressing the gases. This leads to low operation as well as maintenance costs. 

Pump impact on application

It is also very important to evaluate the impact of the vacuum pump on the application or the process. There are multiple variables which can influence your final choice among different vacuum pumps.

• Vibration produced by the pump
• Oil or hydrocarbon emission
• EMC emission
• Noise emission
• Heat emission
• Particle emission
• Magnetic field produced by the pump

Investment and maintenance

Though you must always plan according to what needs to be achieved, there are also other things to be considered. You must know the initial capital costs, the operating costs and the maintenance costs needed in the future. You can understand this through the example of turbomolecular pumps and oil diffusion pumps. The initial cost of TMP is higher than the oil diffusion pump. But if you use them for five years at a stretch, the oil diffusion pumps will cost higher in maintenance than the latter.

So, analyze your needs and requirements and go with LeDab vacuum pumps for the best results.
