VVN or liquid ring vacuum pump is designed to create a vacuum in tanks and pipelines for various technological purposes. As the name suggests, these pumps are based on the principle of creating a vacuum using water. The impeller, placed in a chamber with a certain eccentricity, due to centrifugal force, throws water to the periphery of the working chamber, thereby creating a water ring. Due to the fact that the pump wheel and the water ring it creates are eccentric, the pump creates a vacuum.
Due to their design simplicity, reliability, maintainability, these pumps have found wide application in the food, chemical industry, evaporation plants, dryers, filtration plants and many others.
Pumps of this type are produced by different manufacturers, but the principle of their operation is the same. When selecting a pump of this type, you can find models such as BBH, SIGMA, 2BV, Hydro-vacuum, EVP, Becker, Value.
