2BV liquid ring vacuum pump was initially used as self-suction pump, and then gradually used in many industrial sectors such as petroleum, chemical industry, machinery, mining, light industry, medicine and food. In many industrial processes, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture regain and vacuum degassing, water ring pumps are widely used.
Due to the rapid development of vacuum application technology, the liquid ring vacuum pump has been paid attention to in obtaining rough vacuum. Because the gas compression in the liquid ring vacuum pump is isothermal, it can extract flammable and explosive gases. In addition, it can extract dusty and water-bearing gases. Therefore, the application of 2BV liquid ring vacuum pump is increasing.
