萊寶擴(kuò)散泵油LVO 500技術(shù)參數(shù)

  萊寶擴(kuò)散泵油LVO 500 用于萊寶擴(kuò)散泵DIP系列油。
  萊寶擴(kuò)散泵油技術(shù)參數(shù)：
              LEYBONOL pump fluids for oil diffusion pumps must exhibit a low vapor pressure at room temperature
and must be able to resist thermal decomposition and oxidization. They permit high pumping speeds
over a wide range of pressures.

Surface tension of the pump fluids must be high to reduce "creep" of oil films. They are chemically inert,
exhibit a high flash point and the evaporation heat is low.
