Types Of Vacuum Pump
There are 5 main types of vacuum pumps that you should know about, and each of them is great. The key is to pick the one that matches your use the most, so let’s see what they are.
Diaphragm Vacuum Pump
When it comes to durability, diaphragm vacuum pumps always win. These vacuum pumps are extremely resistant to chemicals and corrosions which is perfect for any type of acidic, corrosive, and viscous products. This type is more ideal for fields such as the chemical industry, cosmetic industry, and food industry. People normally use them to pump creams, gels, chocolate, syrups, water, and more. On top of that, they are dry pumps so they don’t need lubrication with oil and maintenance at all.
Liquid Ring Vacuum Pump
It operates by supplying liquid that is centrifuged on the pump walls to maintain the pump’s airtightness. Liquid ring vacuum pumps are suitable for industries such as distilleries, mines, petroleum refineries, power plants, sugar factories, and more. Since they are not sensitive to the passage of liquids, small solid particles, or vapors, they are convenient to use. You can also use them for explosive and heat-sensitive products as well with a high safety level ensured.
Rotary Vane Vacuum Pump
As for this type, it is compact and small with the ability to reach a level of rough vacuum. This type of vacuum pump is more effective for aqueous samples as well as high-boiling solvents. At the same time, vapors can be captured before they even come into contact with the pump. It requires oil to operate, and that ensures perfect airtightness along with constant and efficient lubrication of the moving part. Plus with excellent heat dissipation, you won’t have to worry about it heating up at all.
Scroll Vacuum Pump
For clean and dry vacuum pumping, scroll vacuum pumps are your guy. Along with that, these vacuum pumps are also common in laboratories and research fields. It uses two spiral-shaped scrolls to pump and compress liquid or gaseous media. One spiral is fixed while the other orbits around it eccentrically which allows the gas to be compressed. The awesome thing about them is that they are compact and quiet, and they don’t require oil at all. When you choose this type, you have to make sure that you give it regular maintenance for long term service.
Turbomolecular Vacuum Pump
The unique thing about this vacuum pump type is that it operates on the same principle as compressors. It can attain pressure levels from 10-12 mbar with flow rates vary from 50 to 5,000 l/s. There are blades of different levels that are rotated by an electric motor rotating at a high speed. This rotating process will remove the air from the volume; hence the mounting on magnetic bearings to support high rotational speeds. These pumps are ideal for ultrahigh vacuum applications such as analytical instrumentation or laboratory analysis. They do not need oil at all, but they can be very expensive to purchase with the requirement of more maintenance.
Finding a fault or general maintenance of cooling or HVAC systems is easier with the best vacuum pumps. The device will eliminate airlocks, contamination, moisture, and other things that may be inside the system. In so doing, it allows the free flow of the refrigerant. This allows the accessory to work at its maximum efficiency. To assist you in picking the right product, we have looked at some of the top choices that are readily available in the market.
