JZJ2B(S) series Roots-liquid ring vacuum unit

Main features:

1. JZJ2B series Roots-liquid ring vacuum unit adopts high efficiency and energy-saving 2BV-type liquid ring vacuum pump as the pre-stage pump, so the JZJ2B series Roots-liquid ring vacuum unit has high efficiency than JZJ2S series Roots-liquid ring vacuum unit, Compact structure, no leakage (2BV series is mechanical seal standard design, different from the packing seal of 2SK series), corrosion resistance (2BV series adopts stainless steel impeller), and the advantages of high grade.
2, Roots water ring vacuum unit of the working fluid of the pre-stage pump is mostly water, can also be used in organic solvents (available methanol, ethanol, xylene, acetone and other organic solvents) or other liquids, the pre-stage pump as a closed-circuit recycling system to use, greatly reducing the pollution of the environment, and at the same time greatly improves the recovery of organic solvents. br/>Three-stage Roots water ring vacuum unit (Roots pump+Roots pump+water ring pump): 25Pa
Four-stage Roots water ring vacuum unit (Roots pump+Roots pump+Roots pump+water ring pump): 0.5Pa
