Liquid-packed ring vacuum pump

Water-ring vacuum pumps are actively used when pumping out gases, as well as those vaporous substances that are not aggressive. The operation is based on the technology of vacuum, which appears in a closed device. The peculiarity of such a pump is that it can only have one working medium that is water.

The water-ring vacuum device is highly reliable, economical, and can work for a long time. For this reason, it is actively used in various production areas. So, the water ring pump is used in the chemical industry, in the processing of wood, pulp, metallurgy, mechanical engineering, for drying some food products, in optics and pharmaceuticals, in construction and perfumes.

Advantages of liquid-packed ring vacuum pumps

This pump works with liquids as well as with gases. However, in order for the device to pump gaseous substances it must first be adapted to them by upgrading. Some parts are replaced so that the device can easily pump even those gases that contain a lot of hard impurities.

Among the positive qualities are:

• maintainability;

• savings (low pump cost);

• the design is very simple;

• usage will not cause difficulties;

• parts practically do not wear out;

• there are no parts that could break frequently.

Liquid-packed ring vacuum pumps of domestic and foreign production

Russia is actively engaged in creating pumps of this type and this is not surprising because their range of operation is very wide, which was noted above. For working with those environments that are aggressive, vacuum pumps marked VVN 3H and VVN 12H are usually used. Their parts that come into contact with substances specifically made of stainless steel brand 12X18H9T.

Among the fundamental advantages of liquid-packed ring vacuum pumpsmade in Russia, we can note the most simplified design, as well as a good level of adaptation to Russian conditions of usage.

In addition, parts for replacement in case of breakdowns are available in abundance, so that the repair of devices will not be difficult. Their installation is very fast, and manufacturers provide customers with both warranty and post-warranty service. Information consultation is also possible.

As for vacuum pumps from foreign manufacturers, they are not so common on the territory of the Russian Federation. Some of their characteristics look much better, in particular ‒ performance. At the same time, they are not as easy to repair as their Russian counterparts due to the small number of spare parts. Foreign water ring pumps are slightly more expensive.
