For many years now Roots Roots Vacuum Pump china vacuum pumps have already 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 higher pumping speed at the lower inlet pressure with high ultimate vacuum. Since the pump running parts haven’t any contact, such as for example rotors and the finish cover, therefore the pump functionality is definitely stable and long service time. low maintenance cost
Applications:
They’re widely used in vacuum smelting, vacuum welding, vacuum casting, vacuum coating, vacuum drying, vacuum dynamic experiment and chemical substance pharmaceutical, electric vacuum device manufacturing industries.
Because of the chemical substance, pharmaceutical and various other industries require large vapor degassing capablity. the sealing structure of roots vacuum pump chamber and the bearing chamber offers improved, which greatly reducing the bearing cavity and equipment cavity oil emulsification. Hence, roots vacuum pump can be more suitable for pumping large levels of drinking water vapor and solvent with drinking water ring vacuum 
pump.
