Oil for Rotary Vane Vacuum Pumps
Selection inputs for vacuum pump oil, focusing on vapor pressure, oxidation stability, and compatibility with process gases.
This page lists neutral selection inputs. Confirm equipment manufacturer specifications before selecting a lubricant.
Operating Conditions
| Operating Parameter | Typical Range/Value |
|---|---|
| Vacuum Level | Higher vacuum requires lower vapor pressure oil |
| Contaminants | Moisture/solvents can degrade oil; consider gas ballast usage |
| Temperature | Continuous operation heats oil; oxidation resistance important |
Required Lubricant Properties
| Required Property | Specification |
|---|---|
| Low Vapor Pressure | Supports target vacuum level |
| Oxidation Stability | Resists varnish and thickening |
| Demulsibility | Separates water where applicable |
