It is suitable for extracting gas and water vapor, and the suction pressure can reach 33mbar (97% vacuum). When using transformer oil as working fluid (called oil ring vacuum pump), the suction pressure can reach 6.7mbar (99.3% vacuum degree), which can replace the reciprocating vacuum pump. When the liquid ring vacuum pump works for a long time under the suction pressure close to vacuum, the cavitation protection pipe should be connected to protect the pump and eliminate the cavitation sound. When used as a compressor, its pressure is as high as 0.26MPa.
