For many years today Roots vacuum pumps have already been well established in the area 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 low inlet pressure with high ultimate vacuum. Because the pump running parts haven't any contact, such as rotors and the end cover, therefore the pump functionality is 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 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 Roots Vacuum Pump china bearing chamber offers improved, which significantly reducing the bearing cavity and 齒輪 cavity oil emulsification. Hence, roots vacuum pump is usually more ideal for pumping large quantities of drinking water vapor and solvent with drinking water ring vacuum pump.
