Turbo Molecular Pump System
YTP Series

For more Information


The YTP series are simple high-vacuum pump system that consist of an ULVAC turbo molecular pump (UTM series pump), rotary pump, forevalve, Pirani vacuum gauge and control system. A single unit can evacuate from atmospheric pressure down to high vacuums.


  • Two types are available:
    Automatic operation type (YTP-SA series) and manual operation type (YTP-M series). In addition, 4 evacuation speeds can be selected.
  • During power failures, the forevalve closes automatically, and the atmosphere in the rotary pump is vented automatically.
    The pump system doesn't operate when the power is restored.
  • The turbo molecular pump uses fluorine-based oil with a saturation vapor pressure of around 10-11 Pa (at 20ºC), so the atmosphere stays completely oil-free.
  • The turbo molecular pump uses high-performance bearings, so doesn't require time-consuming oil changes or bearing replacements.


  • As evacuation systems for analysis equipment
  • As rough vacuum pumps for accelerators and beam lines
  • As high-vacuum pump system for laboratory equipment
