What vacuum fluid should I use in my pump
There are several different types of vacuum pump fluids available to lubricate and run vacuum pumps. The system application usually dictates the type of oil required. There are 3 main types of oil that are commonly used;  Perfluorinated Polyether (PFPE), Hydrocarbon, and Silicon based diffusion fluid.  Fomblin (Solvay) and Krytox (DuPont) are two brands of PFPE fluids.  This fluid is used when aggressive chemical environments or high concentrations of oxygen are present.  Standard industrial applications require hydrocarbon based fluids.  Diffusion pump fluid is a synthetic organo-silicon oxide polymer based oil that has exceptional chemical stability at high temperatures.  IVS offers our customers several choices of these oils with different viscosities and maintains them in stock.
