Vacuum Pump Fluid

Chemours™ Krytox® vacuum pump fluids are used in applications where conventional vacuum pump oils cause safety, waste disposal and maintenance problems. They are nonflammable and eliminate the chance of fire in pumps. They are nonreactive and safe to use in oxygen systems. They can replace competitive PFPE fluids as well as any other type of vacuum fluid. Krytox® fluids do not contain acetal groups, which are susceptible to attack by Lewis acids. (See Figure 2 and Table 4.) This gives Krytox® superior stability as a vacuum pump fluid. Krytox® vacuum fluids are precisely distilled to provide low vapor pressures and give superior performance. (See Figure 1.) In addition, Krytox® fluids are recyclable.  Krytox® XP VPF oils contain a soluble additive to prevent rust. This patented additive enhances the performance of Krytox® VPF fluids, giving them improved performance properties. The long-term antirust properties repel moisture, providing extra protection from corrosion of metal parts and bearing surfaces.
