Roots vacuum pump
For many years 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 ultimate vacuum. Since the pump running parts have no contact, such as rotors and the end cover, so the pump performance is stable and long service time. low maintenance cost
They’re widely used 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, pharmaceutical and other industries require huge vapor degassing capablity. the sealing structure 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 more suitable for pumping large quantities of water vapor and solvent with water ring vacuum pump.
