ZJN Series Air-cooling Roots Vacuum Pump

Summary:

　　ZJQ Series air-cooling roots vacuum pump is in ZJ Roots series vacuum pump based on the increased bypass gas cooling system is designed. Because of its special structural design, make its can run reliably for a long time under the high pressure. Under normal circumstances are in the pump outlet or back flow are installed in the piping for heat exchanger. Cooling gas from both sides of the pump body into the pump cavity and cooling of the rotor and the pump cavity, but the pump pumping performance did not affect. Pump can be used alone can also multiple used in tandem, or with liquid ring vacuum pump in series to form a unit and achieve higher vacuum degree to meet the technological requirements.
