For many years today 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 benefit of roots vacuum pump is a high pumping speed at the low inlet pressure with high ultimate vacuum. Since the pump working parts have no contact, such as for example rotors and the end cover, so the pump overall performance is definitely 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.
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 offers improved, which greatly reducing the bearing Roots Vacuum Pump china cavity and gear cavity oil emulsification. Therefore, roots vacuum pump can be more ideal for pumping large quantities of water vapor and solvent with water ring vacuum pump.
