The types of vacuum pump required, as well as the pricing and robustness of pumps required, will influence your vacuum pump choice.
There are five main types of vacuum pump:
1.Rotary vane vacuum pumps
Rotary vane vacuum pumps are tiny and compact, with a rough vacuum capability. They’re especially good for watery samples and solvents that boil quickly. Before they even come into touch with the pump, vapors can be collected.
The operation of rotary vane vacuum pumps the use of oil. Oil ensures perfect airtightness, continual and effective lubrication of the moving parts, and great heat dissipation to keep the vacuum pump cool.
Regular maintenance, on the other hand, is necessary to ensure the pump’s optimal performance. One downside is the requirement to change the oil on a frequent basis in order to limit the possibility of wear. It is suggested that you replace it after 3,000 hours of use.
2. Diaphragm vacuum pumps
Diaphragm pumps are among the most chemically and corrosion-resistant pump types. As a result, these pumps can handle practically any type of sample, including ones containing a mixture of solvents and acids, making them an excellent choice for both evaporation and concentration.
Because of this feature, diaphragm vacuum pumps are widely employed in industries such as food (for pumping fluids like water, chocolate, and syrups), cosmetics (for creams and gels), and chemistry. They’re also employed for rotational evaporation and volatile compound treatment. Furthermore, they are well-suited to continual use.
3. Liquid ring vacuum pumps
Liquid ring vacuum pumps work by pumping a liquid that is centrifuged against the pump’s walls. As a result, the pump’s airtightness is maintained by a liquid ring.
Distilleries, petroleum refineries, power plants, mines, sugar mills, and other businesses may find liquid ring vacuum pumps beneficial. Liquids, small solid particles, and vapors pass through these vacuum pumps with little sensitivity. Furthermore, their isothermal compression is perfect for explosive and heat-sensitive materials, ensuring great safety. Vacuum filtration, moisture extraction, water removal from pulp during paper production, mineral recovery, and ash management are all possible applications for liquid ring vacuum pumps.
4. Scroll vacuum pumps
Scroll vacuum pumps are used to pump vacuum both wet and dry. As a result, they’re commonly employed in research and laboratories.
Scroll vacuum pumps use two spiral-shaped scrolls to pump and compress liquid or gaseous media. One spiral is stable, while the other rotates eccentrically around it. The gas can be squeezed because of this eccentric movement.
5. Turbomolecular vacuum pumps
The advantage of turbomolecular vacuum pumps is that they do not require any oil. As a result, they are spotless pumps. These pumps are ideal for applications requiring ultrahigh vacuum, such as analytical instruments or laboratory analysis.
