For many years now Roots vacuum pumps have been well established in the area of vacuum technology. In mixture with backing pumps, which compress against the atmosphere, these pumps offer lots of advantages.
Features:
The main benefit of roots vacuum pump is a high pumping speed at the low inlet pressure with high ultimate vacuum. Since the pump running parts haven’t any contact, such as for example rotors and the finish cover, so the pump performance is stable and long service time. low maintenance cost
Applications:
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.
In view of the chemical, pharmaceutical and 
various other industries require huge vapor degassing capablity. the sealing structure of roots vacuum pump chamber and the Roots Vacuum Pump china bearing chamber has improved, which greatly reducing the bearing cavity and gear cavity oil emulsification. Thus, roots vacuum pump can be more ideal for pumping large quantities of water vapor and solvent with water ring vacuum pump.
