For many years right now Roots Roots Vacuum Pump china 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 ultimate vacuum. Because the pump running parts have no contact, such as rotors and the end cover, so the pump 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 huge vapor degassing capablity. the sealing framework of roots vacuum pump chamber and the bearing chamber has improved, which greatly reducing the bearing cavity and gear cavity oil emulsification. Thus, roots vacuum pump is definitely more ideal for pumping large levels of drinking water vapor and solvent with drinking water ring vacuum pump.
