For many years right now Roots vacuum pumps have already been well established in the region 
of vacuum technology. In mixture with backing pumps, which compress against the atmosphere, these pumps offer plenty of advantages.
Features:
The main advantage of roots vacuum pump is a higher pumping speed at the lower inlet pressure with high ultimate vacuum. Because the pump working parts haven’t any contact, such as rotors and the finish cover, therefore the pump functionality is 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 pharmaceutical, electric vacuum gadget manufacturing industries.
In view of the chemical, pharmaceutical and various other industries require huge vapor degassing capablity. the sealing framework of roots vacuum pump chamber and the bearing chamber offers improved, which significantly reducing the bearing cavity and gear cavity oil emulsification. Hence, roots vacuum pump can be more ideal for pumping large levels of drinking water vapor and solvent with water ring vacuum pump.
