2BV water ring vacuum pump is suitable for the extraction of gas and water vapor, the suction pressure can reach 33mbar(97% vacuum). When transformer oil is used as the working fluid (called oil-ring vacuum pump), the suction pressure can reach 6.7mbar(99.3% vacuum), which can replace reciprocating vacuum pump. When the liquid ring vacuum pump works for a long time under suction pressure close to vacuum, the cavitation protection tube should be connected to protect the pump and eliminate the cavitation erosion sound. When used as a compressor, its pressure is up to 0.26MPa.
2BV2-EX and 2BV6 water ring vacuum pumps/compressors are mainly used for removing inflammable and explosive environments, and their performance parameters are the same as those of 2BV2 and 2BV5 series.
2BV series stainless steel vacuum pump can be used in high corrosion resistance and cleanliness requirements of the occasion. 2BV series stainless steel vacuum pump flow parts: pump body, pump cover, disc, impeller material can be selected 304, 316, 316L stainless steel.
