JZJ series Roots water ring unit

The JZJ series Roots water ring unit is a pumping unit composed of a ZJ type Roots pump as the main pump, a 2BV series water ring pump/2BE1 series water ring pump/SK series water ring pump, or a Roots water ring unit as the front-end pump. In addition to being used to remove general gases, it can also extract gases containing moisture, organic solvents, or small amounts of dust. Compared with general mechanical vacuum pumps, it is not afraid of oil pollution, water vapor, and dust. Compared with general water ring vacuum pumps, it has the characteristics of high vacuum degree and high pumping speed under high vacuum conditions.

The working fluid of the front stage pump of the Roots water ring vacuum unit is mostly water, and organic solvents (such as methanol, ethanol, xylene, acetone, etc.) or other liquids can also be used. Using the front stage pump as a closed-loop circulation system greatly reduces environmental pollution and greatly improves the recovery of organic solvents. The ultimate vacuum degree is determined by the saturated vapor pressure of the working fluid.
