Vacuum Pump Maintenance

The purpose of a vacuum pump lubricating oil pump and act as a seal. For performance of this function the oil must have:

Low vapor pressure, did not significantly increase to 125 F (51.7C)
Viscosity low enough for use in 60F (15.6C), but constant up to 125F (51.7C)

These requirements are easily met by low vapor pressure, paraffin-based oil with a viscosity of about 300 SSU (tangential stresses units) at a price of 100F (37.8C) and viscosity index in the range from 95 to 100. This type of uninhibited oil freely on the market. This material provided almost all sellers of oil vacuum pump for cooling trade..
