For many years right now Roots vacuum pumps have been well established in the area of vacuum technology. In combination with backing pumps, which compress against the atmosphere, these pumps offer lots of advantages.
The main advantage of roots vacuum pump is a high pumping speed at the lower inlet pressure with high Roots Vacuum Pump china ultimate vacuum. Because the pump running parts haven’t any contact, such as rotors and the end cover, so the pump overall performance can be stable and long service time. zero-maintenance cost
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.
Because of the chemical, pharmaceutical and other 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. Hence, roots vacuum pump is definitely more ideal for pumping large quantities of water vapor and solvent with water ring vacuum pump.
