- water ring roots vacuum pump units
■water ring roots unit structure features
1.thanks to the energy efficient 2bv/2be1/2be1s serieswater ring pumpused as a foreline pump, it has the advantages of high efficiency, compact structure, no leakage, corrosion resistance and high protection level.roots water ring vacuum unitthe working fluid of the foreline pump is mostly water, organic solvent (organic solvent such as methanol, ethanol, xylene, acetone, etc.) or other liquid can be used, and the foreline pump is used as a closed loop system, which greatly reduces the environment. the pollution, while greatly improving the recovery of organic solvents. the ultimate vacuum is determined by the saturated vapor pressure of the working fluid.
2.in addition to being used to remove general gases, it can also pump gases containing moisture, organic solvents or small amounts of dust. compared with general mechanical vacuum pumps, it is not afraid of oil pollution, and is not afraid of water vapor and fine dust. compared with general water ring vacuum pumps, it has the characteristics of high vacuum and high pumping speed under high vacuum conditions.
