VACUUM PUMP OIL

 

 

 

Description : Special oil for the lubrication of high vacuum pumps.

 

 

Application : Recommended for use in the majority of high vacuum pumps working with an absolute pressure of 50 microns of mercury (or 0,05 torr) or even lower.

 

 

Properties :

  • Exact viscosity for fast and uniform oil distribution and perfect sealing of the narrow passages between pump blades, rotor and cylinder walls.
  • Very low vapour pressure. Good film strength for minimum friction and lowest possible wear.
  • Suitable water separating properties. High oxidation stability for extended oil life time. Relatively low water content.
  • Specially adapted for vacuum type applications in the refrigeration industry.
