For many years at this point Roots vacuum pumps have already been well established in the region of vacuum technology. In mixture 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 low inlet pressure with high ultimate vacuum. Since the pump working parts have no contact, such as for example rotors and the end cover, therefore the pump performance is definitely 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.
Because of the chemical substance, pharmaceutical and other Roots Vacuum Pump china industries require huge vapor degassing capablity. the sealing structure of roots vacuum pump chamber and the bearing chamber offers improved, which significantly reducing the bearing cavity and gear cavity oil emulsification. Thus, roots vacuum pump is usually more ideal for pumping large levels of water vapor and solvent with water ring vacuum pump.
