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 plenty of advantages.
The main benefit of roots vacuum pump is a high pumping speed at the low inlet pressure with high ultimate vacuum. Because the pump running parts have no contact, such as rotors and the finish cover, so the pump efficiency 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 gadget manufacturing industries.
In view of the chemical, pharmaceutical and additional industries require large vapor degassing capablity. the sealing structure of roots vacuum pump chamber and the bearing chamber provides improved, which significantly reducing the bearing cavity and gear cavity oil emulsification. Therefore, roots vacuum pump is definitely more suitable for pumping large levels of water vapor and solvent with drinking water ring vacuum pump.
