For many years today Roots Roots Vacuum Pump china vacuum pumps have already been well established in the region of vacuum technology. In combination with backing pumps, which compress against the atmosphere, these pumps offer lots of advantages.


The main advantage of roots vacuum pump is a high pumping speed at the low inlet pressure with high ultimate vacuum. Because the pump working parts haven’t any contact, such as rotors and the end cover, therefore the pump performance is usually stable and lengthy service time. low maintenance cost


They’re widely used in vacuum smelting, vacuum welding, vacuum casting, vacuum coating, vacuum drying, vacuum dynamic experiment and chemical pharmaceutical, electric vacuum gadget manufacturing industries.

Because of the chemical, pharmaceutical and additional industries require large 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. Thus, roots vacuum pump can be more suitable for pumping large quantities of water vapor and solvent with drinking water ring vacuum pump.
