VACUMEX
VACUMEX vacuum pump oils are a special line of oils formulated with hydrocracked base oils and specific ashless performance additives to meet the most demanding conditions in the vacuum pumps. Due to the inherently high viscosity index of these lubricants, no additional VI improvers are required in the formulation and so the products remain stable to shear forces and do not suffer any irreversible effects. They also have good compatibility with natural rubber and synthetic seal technology.
