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.
