For many years at this point 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 advantage of roots vacuum pump is a higher pumping speed at the lower inlet pressure with high ultimate vacuum. Since the pump working parts have no contact, such as rotors and the end cover, so the pump functionality can be stable and long service time. low maintenance cost
They’re trusted in vacuum smelting, vacuum Roots Vacuum Pump china welding, vacuum casting, vacuum coating, vacuum drying, vacuum dynamic experiment and chemical pharmaceutical, electric vacuum gadget manufacturing industries.
In view of the chemical substance, pharmaceutical and other industries require huge 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. Thus, roots vacuum pump is definitely more suitable for pumping large quantities of drinking water vapor and solvent with drinking water ring vacuum pump.
