Direct, Differentially Pumped

  • Continuous rotary motion
  • Manual actuator
  • UHV or HV compatible materials
  • Differentially pumped, Dual Viton® elastomer shaft seal
  • Bakeable to 100ºC
  • Del-Seal™ CF and Kwik-Flange™ port mounts

Differentially pumped direct drive rotary motion feedthroughs provide 100 lb-in maximum rotational torque and 500rpm maximum rotation. The rotary shaft is supported by two radial bearings located inboard of dual Viton® elastomer shaft seals. The region between the seals can be differentially pumped through the 1/8" female pipe thread port provided and thus attain UHV compatibility to 10-9 Torr. Feedthroughs are available on industry standard Conflat® compatible Del-Seal™ CF metal seal flanges or ISO KF Kwik-Flange™ port mounts.
