Ultra Oil 19
Description
Dinesh High Vacuum Engineering Ultra Oil 19 (DUO 19) is a premium-grade, hydrotreated hydrocarbon vacuum pump oil engineered for small-to-medium two-stage rotary vane vacuum pumps. Specially formulated to serve as a direct, high-performance equivalent to Edwards Ultragrade 19, DUO 19 delivers identical viscosity profiles, exceptional thermal stability, and low backstreaming under demanding industrial and laboratory environments.
Unlike standard solvent-refined lubricants, DUO 19 undergoes a rigorous hydrotreating process. This severe molecular refining completely eliminates sulfur, nitrogen, oxygen, and aromatic ring structures, leaving a virtually transparent, chemically inert base stock. When combined with our advanced anti-oxidant, anti-wear, and rust-inhibiting additive package, DUO 19 enables your vacuum infrastructure to run cooler, pull deeper ultimate vacuums, and extend oil drain intervals by resisting chemical degradation.
🛡️Key Features & Technical Benefits
-- 100% Drop-In Edwards Ultragrade 19 Equivalent :- Seamlessly mix or switch during routine maintenance without flushing risks or seal compatibility issues.
-- Ultra-Low Vapor Pressure :- Minimizes backstreaming and oil degradation, allowing your vacuum pumps to reach their maximum engineered ultimate vacuum levels.
-- Optimized Cold-Start Lubrication :- Perfectly balanced viscosity profile reduces startup torque requirements, protecting internal mechanical components from dry friction wear during initial cold starts.
