Turbo Pump

Turbomolecular Pumps

A Turbomolecular Pump is a transfer type, mechanical high vacuum pump that consists of a rotating turbine blade (rotation speeds as high as 90k rpm) which imparts kinetic energy on the gas causing the molecules to move towards the turbomolecular pump exhaust. All EBARA  turbo pumps are compound turbo pumps which add a second molecular drag stage to the same shaft. The addition of this stage increases the compression ratio of the pump and also greatly increases the highest allowable foreline pressure of the pump.

Ebara Model EMT Turbomolecular Pumps

EBARA'S MAGNETIC LEVITATED TURBO PUMPS

The EMT Series Turbomolecular Pumps are 5-axis magnetically levitated vacuum pumps that are completely hydrocarbon free. These pumps are suitable for varied applications from the harshest semiconductor application as well as ultra-high vacuum and ultra-low vibration applications.

Beside the Standard Version, the EMT Series offers five major types of turbomolecular pumps - temperature-controlled, corrosion resistant, ultra low vibration, radiation resistant, and ultra high vacuum.

The EMT Series turbomolecular pumps features a wide pressure range with maximum back pressure up to 3 Torr.

The temperature controlled model turbomolecular pumps reduce the rate condensation of the byproduct and process effluent build up commonly found inside a turbomolecular pump. The patented thermal insulation structure with integrated temperature management system is the most energy efficient temperature controlled turbomolecular pump on the market today.

The Ultra high vacuum model turbomolecular pumps efficiently evacuate the lightest gases from high vacuum down to the ultra high vacuum region by reducing the materials' out gassing and improving the efficiency of hydrogen compression. The Ultra high vacuum model turbomolecular pump can achieve 10-10 mbar (10-8 Pa) with a short bake-out period.

The Ultra Low Vibration model turbomolecular pumps meets today's cutting edge challenges in EUV lithography, Micro-machining (MEMS), CD line width measurement, SEM/TEM Electron Microscopy, XPS and Nano-technology analytical tools. The Ultra low vibration model turbomolecular pumps produce less than 1nm vibration amplitude.

Technical Characteristics:

  • Full magnetic bearing
  • Installation in any orientation
  • High throughput
  • Compact size
  • Rotational speed control
  • Vibration free
  • Air or water cooled
