TW mineral oil

TW has been developed for applications where rotary pump oils are likely to be exposed to reactive or corrosive gases.

Features and Benefits

  • The oil is distilled hydrocarbon containing no additives, but unsaturates and aromatic links have been removed.
  • The result is that the oil will last up to 20 times longer, depending on process, than refined mineral oils.
  • Longer oil life significantly extends the intervals between oil changes.

Applications

Edwards TW has been developed for applications where rotary pump fluids are likely to be exposed to reactive or corrosive gases:
  • Distillation
  • Semiconductors
  • Chemical pumping
