For many years now 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 plenty of advantages.
Features:
The 
main benefit of roots vacuum pump is a high pumping speed at the lower inlet pressure with high ultimate vacuum. Because the pump operating parts haven’t any contact, such as for example rotors and the end cover, therefore the pump functionality is stable and long service time. zero-maintenance cost
Applications:
They’re widely used 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 huge vapor degassing capablity. the sealing framework of roots vacuum pump chamber and the bearing chamber offers improved, which greatly reducing the bearing cavity and equipment cavity oil emulsification. Therefore, roots vacuum pump can be more ideal for pumping large levels of drinking water vapor and solvent with water ring vacuum pump.
