To get airless space in the tank, special vacuum pumps are used. Scope of application of these appliances has now expanded significantly, and at the end of the last century, such equipment could be found in research centers or in the space industry. Vacuums differ not only in overall dimensions and price, they have different specifications and designs. Choose the optimal model will help recommendations of our experts.
How to choose a vacuum pump
Pump power. Most vacuum pumps are driven driven by electric motors. Of their power often depends on the speed of pumping air or gas mixture. But not worth it make your choice based only on this parameter. More than engine power, the higher power consumption. Moreover, applying modern designs and technologies, manufacturers succeed increase model performance without increasing power electric motor. Most often for production purposes units with power from 0.5 to 12 kW are used.
Residual pressure. Theoretically at full vacuum residual pressure in the vessel should be 0 mbar. This means that neither There is no one molecule inside the container.
- In practice, such a vacuum is unattainable, so the battle is for lower limit 0.0005 mbar. This mark can only be reached high vacuum pumps.
- In production, there is often enough residual pressure at a level 0.01-1000 mbar. Low vacuum is able to cope with this task. models.
Rated performance. Another major the indicator must be considered when choosing a vacuum pump. it the rate of evacuation of the gas mixture from a vessel with a limited volume. The faster the vacuum box removes air, the higher it performance. Speed range is enough wide, it all depends on the purpose of the device. In selected industries enough production and 30-40 cubic meters. m / h, and in some areas productivity reaches 30000-40000 cu. m / h
Design features. Major impact on the core The parameters of a vacuum pump are exerted by its operating principle. Wide The following designs are used.
- The best selling are rotary vane oil sealed single stage models. Their performance ranges from 4 to 1600 cubic meters. m / h at a residual pressure of 0.1 mbar. They are simple and reliable, but often have to maintenance.
- Dry rotary vane models are characterized by a clean vacuum. since grease is not used in the construction. But achieve good the vacuum level fails (100-1000 mbar). Pumping speed makes 3-500 cubic meters. m / h
- Liquid ring vacuum cleaners can pump dirty gas mixtures. They are low cost, but consume a lot. electricity and water. This is an old type of pump a vacuum of 30-1000 mbar and a pumping speed of 3-45000 cubic meters. m / h
- A good combination of reliability and vacuum depth (0.5-1000 mbar) can be obtained from diaphragm pumps. They work quietly, have compact sizes. But application is limited to laboratory studies due to insufficient productivity (0.5-16 cubic meters. m / h).
We selected 5 of the best vacuum pumps in our review. They all found its application in our country and received high marks. At rating was taken into account the opinion of experts and reviews consumers.

The best low vacuum pumps
The most widely used in various areas of production are low vacuum pumps. They are used when packaging products. food, participate in the operation of the equipment, help to conduct laboratory research. Experts have chosen several reliable models.
The English company Edwards has developed a new series of oil-free (spiral) pumps of the XDS series. Developers applied innovative bellows motion input technology. Thanks this design was able to completely isolate the working chamber, preventing lubricants from entering it. Experts highly rated high pumping speed (35-95 cubic m / h), low level noise, small residual pressure (0,007-0,01 mbar), economic electricity consumption (0.52 kW). Model becomes winner of our ranking.
The vacuum cleaner is widely used, starting with chemical laboratories and ending with spray coating areas. Reviews consumers are positive. Only flaw units of this series is high cost.
- innovative design;
- stable work;
- ease of installation;
- ease of operation.
- high price.
Samson pumps ke
A worthy competitor to British pumps is products from Denmark Samson Pumps KE. This series of vacuum cleaners is used for evacuation of a gaseous medium from technological tanks. Water ring models are in demand in the food and mining industries, in oil production and even in industrial fishing. Experts note high pumping speed (150-320 cubic m / h), because the device It works on the principle of a volumetric hydraulic machine. Pump differs in compactness and durability. In terms of residual pressure model is inferior to the leader of the rating (33-100 mbar), and the power consumption of the unit is also higher (4-11 kW).
Cons include high build quality, compactness and inexpensive maintenance. Low vacuum counts The main disadvantage of Danish pumps.
- high-quality manufacturing;
- compact sizes;
- strength and durability;
- high pumping speed.
- low vacuum.
German Busch R5 vacuum pumps are widely used in food and light industry. Thanks to the rotary blade design manages to create a low vacuum (up to 0.1 mbar). And at least the price of German Vacuums are quite high; they are popular in different countries, including Russia. This fact is confirmed. the simultaneous operation of 2.5 million Busch R5 pumps on our the planet. For the optimal combination of performance and residual pressure model takes an honorable third place in the ranking.
Russian users are offered a variety of models, along with universal pumps in the series there are also highly specialized aggregates. The advantages include consumers smooth flow and low noise, simplicity and reliability.
- high efficiency;
- variety of models;
- high-quality manufacturing;
- high price;
- scope is limited.
Top high vacuum pumps
Innovative product development often requires high vacuum pumps. Their task is to create a deep and clean vacuum. Such devices work in research institutes in astronautics and medicine. Specialists praised abilities of several units.
Well-known Swiss company Oerlicon produces cryogenic Leybold COOLVAC pumps. They work on the principle of refrigeration. installation. The equipment features a very clean vacuum, low vibration, high performance. In the series there are 10 modifications, the consumer will easily find the most suitable option. The scope of this unit is wide, starting with production of laboratory equipment and ending electron beam welding. For high quality workmanship and exceptional cleanliness of the vacuum pump is the winner of our rating.
Users note that no purge is required during operation nitrogen, you can control the unit using a PC. Disadvantages the high price and the need for regular regeneration.
- high purity of vacuum;
- ease of use;
- low vibration;

The turbomolecular model is used in the most high-tech areas of production and in scientific human activities. Achieve a high vacuum purity the manufacturer succeeded due to improved bearings, which work on dry lubricant. Experts appreciated low vibration of the unit, high speed and durability. The American vacuum cleaner is inferior to the European in the assortment wealth. The series includes only 5 modifications.
Users are satisfied with high performance, quality vacuum, reliability, modern design and simplicity operation. Of the minuses, a high price and limited the lineup.
- high speed;
- pure vacuum;
- low vibration;
- high price;
