Edwards' Ultragrade™ Performance Vacuum Lubricants
Ultragrade™ Performance vacuum lubricants are ideal for industrial and high-vacuum applications. Developed specifically for applications that require low vapor pressure while working at high stresses and high temperatures, they can be used in large, heavy-duty vacuum pumps as well as in smaller vacuum pumps. The lubricants benefit from improvements in formulation, handling and packaging that result in a finer product for oil-sealed vacuum pumps. Ultragrade Performance base oils are refined without the uses of solvents for extreme purity. The base fluids are combined with selected additives to provide a formulation resilient to the stresses of mechanical pumping.
