Multistage Dry Vacuum Pump Gas Way


CZPT dry vacuum pump Gasoline Way


  • Airflow route radial, Corrosive approach fuel does not attack the bearing and gear axially immediate
  • Airflow path axial, Corrosive procedure attack the bearing and equipment axially in gear cap violent
  • Method gas is compressed uniformly in each and every stage of rotors. Uniform compression heat, so decrease exhaust fuel temperature
  • The method gas is compressed centrally at the finish of screw, so higher exhaust gasoline temperature and screw
  • Approach gas could contact with far more cooling jacket floor, high heat dissipation performance
  • Method gasoline could speak to with handful of cooling jacket surface, reduced heat dissipation
  • Roots rotor is much more resistant to particles and adherents, number of impacts on its functionality after its surface use and corrosion
  • CZPT rotor is unsuitable for particles and adherents, big impacts on its performance soon after its surface dress in and corrosion
