For many years now Roots vacuum pumps have been well established in the area of vacuum technology. In mixture with backing pumps, which compress against the atmosphere, these pumps offer lots of advantages.
Features:
The main benefit of roots vacuum pump is a high pumping speed at the low inlet pressure with high ultimate vacuum. Because the pump operating parts haven’t any contact, such as rotors and the end cover, therefore the pump efficiency can be stable and long service time. low maintenance cost
Applications:
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 substance, pharmaceutical and various other industries require large 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. Therefore, roots vacuum pump is more suitable for pumping large quantities of drinking water vapor and solvent with water ring vacuum pump.
