2BV water ring vacuum pump is suitable for pumping gas and water vapor, inspiratory pressure can reach 33mbar absolute pressure (97% vacuum degree). When using transformer oil as working fluid (called the oil ring vacuum pump), suction pressure can reach 6.7mbar absolute pressure (99.3% degrees), can completely replace the reciprocating vacuum pump. When the liquid ring vacuum pump in the suction pressure close to the limit vacuum under the long-term work, should be connected to the cavitation protection tube, in order to protect the pump and eliminate cavitation noise. When used as a compressor, the pressure is maximum to 0.26MPa (absolute pressure). As the compressor is used, with the increase of the exhaust pressure will cause the increase of the 2BV pump power, the order should indicate the exhaust pressure to select the appropriate motor power.

2BV2-Ex, 2BV6 series water ring vacuum pump / compressor is mainly used for pumping explosive gas, and in all kinds of flammable and explosive environment, its performance parameters and 2BV2, 2BV5 series of the same model.

2BV series stainless steel vacuum pump can be used in various corrosion resistance requirements of the occasion and cleanliness requirements of the occasion. According to the working conditions of 2BV series stainless steel vacuum pump all over flow parts: pump body, pump cover, disc, impeller material can choose 304, 316, 316L and other types of stainless steel.
