For many years now Roots Roots Vacuum Pump china 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 advantage of roots vacuum pump is a higher pumping speed at the low inlet pressure with high ultimate vacuum. Because the pump running parts have no contact, such as for example rotors and the end cover, therefore the pump efficiency is usually stable and lengthy service time. zero-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.
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 greatly 
reducing the bearing cavity and equipment cavity oil emulsification. Therefore, roots vacuum pump is more ideal for pumping large quantities of drinking water vapor and solvent with drinking water ring vacuum pump.
