2BV Series
The 2BV series water ring vacuum pumps are suitable for pumping out gases and water vapor, and the suction pressure can reach 33mbar absolute pressure (97% vacuum degree). When transformer oil is used as the working fluid (called oil ring vacuum pump), the suction pressure can reach 6.7 mbar absolute pressure (99.3% vacuum). When the liquid ring vacuum pump works for a long time under the suction pressure close to the ultimate vacuum, it should be coupled with a cavitation protection tube to protect the pump and eliminate the cavitation sound. When used as a compressor, the increase in discharge pressure will cause the 2BV Series pump power to increase, and the discharge pressure should be indicated when ordering in order to select the appropriate motor power.
