Roots liquid ring vacuum unit

The unit is composed of Roots pump and corrosion-resistant liquid ring vacuum pump according to a certain pumping speed proportional relationship. It has the characteristics of large pumping speed, high ultimate vacuum and low power consumption. Compared with reciprocating pumps and spool valve pumps, it is more fuel-efficient, low-noise, and less polluting. In the case of keeping the pumping volume unchanged, if it is combined with a frequency conversion control cabinet, it saves 60 ~ 80 electricity than reciprocating pumps and liquid ring vacuum pumps %.
