JZJ Series Roots Water Ring Unit

       JZJ Series Roots Water Ring Unit

       JZJ series Roots water ring unit is a pumping unit composed of ZJ type Roots pump as the main pump and 2BV series water ring pump/2BE1 series water ring pump/SK series water ring pump or Roots - water ring unit as the pre-stage pump. It can not only be used to pump out general gases, but also gases containing moisture, organic solvents or a small amount of dust. Compared with general mechanical vacuum pumps, it is not afraid of oil contamination, moisture and fine dust, while compared with general water ring vacuum pumps, it is characterized by high vacuum degree as well as high pumping speed under high vacuum condition.

　　Roots water ring vacuum unit of the working fluid of the pre-stage pump is mostly water, can also use organic solvents (available methanol, ethanol, xylene, acetone and other organic solvents) or other liquids, the pre-stage pump as a closed-circuit recycling system, greatly reducing the pollution of the environment, while greatly improving the recovery of organic solvents. Its ultimate vacuum is determined by the saturated vapor pressure of the working liquid.
