For many years right now Roots vacuum pumps have already been well established in the area of vacuum technology. In combination with backing pumps, which compress 
against the atmosphere, these pumps offer plenty of advantages.
Features:
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 for example rotors and the finish cover, therefore the pump overall performance is certainly stable and lengthy service time. zero-maintenance cost
Applications:
They’re trusted in vacuum smelting, vacuum welding, vacuum casting, vacuum coating, vacuum drying, vacuum dynamic experiment and chemical substance pharmaceutical, electric vacuum gadget manufacturing industries.
In view of the chemical substance, pharmaceutical and additional 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 gear cavity oil emulsification. Hence, roots vacuum pump is more suitable for pumping large levels of drinking water vapor and solvent with drinking water ring vacuum pump.
