Water ring vacuum pumps and compressors are widely used in petrochemical, pharmaceutical, food, sugar industry and other fields, due to compression of gas in the work process is isothermal, so in the compression and pumping flammable explosive gas, not dangerous, its application is more widespread.

The 2BV series vacuum pumps are suitable for pumping gas and water vapor, the suction pressure can reach 33mbar will pressure (97% vacuum), when the vacuum pump gas pressure is less than 80mbar under the condition of long-term work, should be connected to the pump cavitation protection tubes protection, such as with the air jet, the suction pressure can reach 10mbar.
