Oil Recommendation
For Busch R5 oil-sealed rotary vane pumps, VPS M100 is the standard mineral oil recommendation unless your pump tag, process, or facility specification calls for synthetic, food-grade, PFPE, or another specialty oil.
Shop VPS M100 Vacuum Pump Oil or use the Vacuum Pump Oil Cross Reference Chart if your application requires a different oil.
