For many years at this point Roots vacuum pumps have 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 benefit of roots vacuum pump is a higher pumping speed at the lower inlet pressure with high ultimate vacuum. Since the pump working parts haven’t any contact, such as for example rotors and the end cover, so 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 pharmaceutical, electric vacuum device manufacturing industries.
In view of the chemical substance, pharmaceutical and additional industries require large vapor degassing capablity. the sealing framework of roots vacuum pump chamber and the bearing chamber offers improved, which greatly reducing the bearing cavity and gear cavity oil emulsification. Therefore, roots vacuum pump is certainly more suitable for pumping large quantities of drinking water vapor and solvent with drinking water ring vacuum pump.
