Vacuum Pump Oil 19 – High-Performance Ultragrade 19 Equivalent Ensure reliable vacuum depth and long-lasting mechanical protection with Vacuum Pump Oil 19, a premium hydrocarbon mineral fluid engineered as a direct replacement for Edwards ULTRAGRADE™ Performance 19. Formulated using a severe hydrotreating refining process, Vacuum Pump Oil 19 eliminates impurities like sulfur, nitrogen, and aromatic hydrocarbons. This results in a highly stable base oil that resists oxidation, sludge formation, and thermal breakdown even under continuous heavy-duty cycling. Specifically optimized with a standard ISO VG 68 viscosity grade, this fluid ensures a perfect internal sealing barrier and superior wear protection for small-to-medium-sized laboratory and industrial rotary vane pumps. Key Features & Benefits: - Direct Ultragrade 19 Drop-In :- Functions as a seamless alternative to Edwards 19 oil without requiring complex flush cycles or modifications. - Optimized Viscosity Sealing :- Perfect for single-stage and two-stage mechanical pumps, maintaining tight tolerances to achieve maximum ultimate vacuum. - Low Vapor Pressure :- Minimizes internal oil volatilization and backstreaming, keeping your vacuum process free of contamination. - Excellent Water Separation :- Resists emulsification, allowing the oil to easily separate from moisture and process gases for cleaner operation. Primary Equipment Compatibility: - Edwards RV series pumps (RV3, RV5, RV8, RV12) - Edwards E2M series rotary vane pumps (E2M0.7 to E2M18) - Labconco, Welch, and Savant rotary vane vacuum pumps - Standard industrial and laboratory backing pumps requiring an ISO VG 68 vacuum fluid.
