For many years right now Roots vacuum pumps have been well established in the area of vacuum technology. In combination with backing pumps, which Roots Vacuum Pump china compress against the atmosphere, these pumps offer lots of advantages.
The main benefit of roots vacuum pump is a high pumping speed at the lower inlet pressure with high ultimate vacuum. Since the pump operating parts have no contact, such as rotors and the finish cover, so the pump functionality can be stable and long service time. low maintenance cost
They’re trusted in vacuum smelting, vacuum welding, vacuum casting, vacuum coating, vacuum drying, vacuum dynamic experiment and chemical pharmaceutical, electric vacuum device manufacturing industries.
Because of the chemical substance, pharmaceutical and other industries require huge vapor degassing capablity. the sealing structure of roots vacuum pump chamber and the bearing chamber provides improved, which greatly reducing the bearing cavity and equipment cavity oil emulsification. Hence, roots vacuum pump is definitely more suitable for pumping large quantities of water vapor and solvent with water ring vacuum pump.
