 Roots vacuum pump is mainly composed of a pair of “8”-shaped rotors which synchronous rotate with high speed, and two semi-circular chambers. This kind of profile can ensure the higher pumping stability even at low pressure. And the pumping rate as well as vacuum degree can be improved greatly in effective working limit when combines with screw vacuum pumps, rotary vane pumps, piston pump etc.

Advantage
With ZJL roots vacuum pump, a high vacuum degree can be reached within short time. The service life is prolonged with adopting of mechanical seal, which carries a build in “oil cup” and oil slinger for lubricating. Simultaneously, the inside multiple seals device can ensure no oil return into the pumping chamber. Thus a high purified vacuum can be promised. The whole pump is made of aluminum alloy for corrosive resistance and heat radiating. Besides, it has low noise and a compact-size.
Application
They are widely used in lighting, solar energy, electronics, semiconductors, vacuum drying, leak detection equipment, vacuum casting, vacuum melting, vacuum degassing, vacuum coating industry and vacuum distillation of the chemical pharmaceutical industry etc.
