For many years today Roots vacuum pumps have been well established in the region of vacuum technology. In combination with backing pumps, which compress against the atmosphere, these pumps offer lots of advantages.
The main benefit of roots vacuum pump is a higher pumping speed at the lower inlet pressure with high ultimate vacuum. Because the pump operating parts haven’t any contact, such as rotors and the finish cover, so the pump efficiency is stable and lengthy service time. zero-maintenance cost
They’re trusted 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 additional 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 equipment cavity oil emulsification. Thus, roots vacuum pump is certainly more suitable for pumping large quantities of water vapor and solvent with water ring vacuum pump.
