JZJQY tri-lobe gas-cooled Roots/Liquid ring vacuum pumping system is made of the gas-cooled Liquid Vacuum Pump Roots vacuum pumps as the main pump and the liquid ring vacuum Pump Seal as the fore pump. As the system is equipped with the liquid ring vacuum pumps as the fore pump, it is particularly suitable for pumping the high humidity gas with much vapor, the condensable and corrosive gases in the industrial processes. Using the pumping medium as the working liquid in the ring pump can recycle the medium internally and reduce the waste emission significantly, which has bigger environmental and energy saving advantages over the JZJQS type vacuum system.
