Oil Diffusion Pump pfl series

PFL-type oil diffusion pump is designed and manufactured based on our extensive research and manufacturing experience. It is used in many high-vacuum production facilities, and its practical performance is highly appreciated.

Features

  • Excellent pumping speed
  • Low back-streaming of the operating fluid
  • Minimized power required and fluid capacity to ensure low operating cost
  • Easy maintenance
  • Reliable pump body construction

*1 The ultimate pressure by an ionization gauge in the case of coolant temperature 20 degrees Ceisius.
*2 The backing pump chooses it for the maximum throughput of the diffusion ejector pump,but,in consideration of time of starting pressure,it is good to use a big backing pump.
*3 Please confirm other dimensions by CAD data placing in the ULVAC,Inc.website.
