Selection of 2BV water ring vacuum pump

The 2BV series water ring vacuum pump is a single stage pump with integral structure and machine pump. The shaft seal adopts mechanical seal, which has the characteristics of simple structure, simple installation, no oil, safety and reliability.

2BV series water ring vacuum pumps are suitable for pumping out gas and wet steam. The suction pressure can reach 33 mbar absolute pressure (97% vacuum degree). When 2BV water ring vacuum pumps are working for a long time under the suction pressure lower than 80 mbar, cavitation protection tube should be connected to protect the pump. 2BV water ring vacuum pumps such as air ejector suction pressure. Up to 10mbar, the ejector can be installed directly on the suction port of the vacuum pump. When used as a compressor, the maximum pressure is 0.26MPa (absolute pressure).

2BV series water ring vacuum pumps and compressors are widely used in petroleum, chemical, pharmaceutical, food, sugar industry and other fields. Because the gas compression process is isothermal in the working process, it is not easy to explode when compressing and pumping inflammable and explosive gases, so it is more widely used.
