Turbo Molecular Pump

UTM-MI Series



Controller integrated turbo molecular pump with magnetic bearings saves wiring work and installation space.


  • Controller integrated with the pump body
    No wiring work between pump body and controller.
  • Free mounting direction
    Free mounting direction makes the system design flexible.
  • 5 models from 1000L/s to 4000L/s class.
  • Wide range and high flow for the light processes.
  • Pump rotation variable from 25% to 100%
    Enabling the pressure adjustment in a chamber.
  • High durability and safety
    Safety confirmation tests are passed, such as air
    rushing-in test and touch down test.


    • Main vacuum pumping system for equipment
      ・Semiconductor equipment
      ・Evaporator,Sputtering system
      ・Analytical equipment,Experimental device and etc.
    • Main vacuum pumping system for the light processes that do not generate side reaction products.
    • Replacement from oil diffusion pumps
    • General use for high vacuum evacuation system.
