Vaccum Oil

Vacuum Pump Oil is a high viscosity index, medium viscosity lubricant made from very high quality solvent refined base oils for the lubrication of vacuum pump cylinders. Vacuum Pump Oil has good chemical stability enabling it to resist oxidation and the subsequent formation of sludge and deposits, an essential characteristic in all cases where continuous service in involved. This enables the oil to retain its original properties such as viscosity and demulsibility and so prolong oil service life.
Water vapour is a common contaminant in vacuum systems and tends to condense in pumps, oils separators and reservoirs. Mobil Vacuum Pump Oil has good demulsibility to separate readily from water. This aids water removal and prevents its return to metal surfaces to cause rust and corrosion.

1. Low volatility characteristics
2. Good air release properties to provide efficient pump operation
3. Good demulsibility to separate quickly from water and resist emulsion formation
4. Good wear protection under start-up and boundary conditions
5. Long service life due to good chemical and thermal stability and less deposit formation
