Description Supervac manufactures a complete range of Diffusion Pump Oils. These oils conform to international standards, passing through stringent tests and quality parameters. Therefore, they are compatible with all makes and models of diffusion pumps manufactured anywhere in the world. In other words, these oils are suitable for all Varian, Ulvac, HHV and any other Korean, Japanese, or Chinese diffusion pumps. SupervacTM SV-SIGMA FAST, SIGMA and SIGMA+ oils are manufactured specially for achieving high to ultra-high vacuum and for enabling rapid pumping or large volumes of gas/vapor during the production process.
SupervacTM SV-SIGMA FAST Diffusion Pump Oil This is a Silicone Fluid manufactured specially for fast pumping of gas/vapor from the system. It can produce vacuum of the order of 10-6 Torr. It is an exact equivalent/replacement of the nowdiscontinued Dow Corning DC 702 Diffusion Pump Fluid. SupervacTM SV-SIGMA Diffusion Pump Oil This is single component silicone oil designed especially for high vacuum of the order of 10-7 Torr. A premier product of Supervac, this oil exhibits excellent hardness when pumping out corrosive or moisture-laden gasses/vapors. SV-SIGMA is an exact equivalent/replacement of Dow Corning DC 704 fluid, Indomet Tetra, CVC4 oil, Hivac F4, Ulvoil D31. SupervacTM SV-SIGMA+ Diffusion Pump Oil This is single component silicone oil designed specifically for ultra-high vacuum of the order of 10-9 Torr. A premier product of Supervac Industries, SV-SIGMA+ has an extremely low vapor pressure, minimal back streaming rate and almost negligible creep. This is an exact equivalent/replacement of DC 705, Indomet Penta and Hivac F5. SV-SIGMA+ is most suited for ultrahigh vacuum applications. Features and Benefits of SupervacTM Diffusion Pump Oils 1. Compatible with all Diffusion PumpsSupervac Diffusion Pump Fluids conform to international standards and are suitable for all types and makes of diffusion pumps around the world. 2. Minimal Back StreamingSince the vapor pressure of the entire ‘Sigma’ range of Diffusion Pump Oils is very low, it creates little to no back streaming which can be a major headache for engineers. 3. Prolonged Service LifeSince these oils are silicone fluids, they exhibit exceptional thermal and chemical stability. These oils are highly resistant to moisture. Thus, they offer a long working life without degenerating or cracking. 4. Less maintenance of System RequiredBeing Silicone Oils, SupervacTM range of diffusion pump oils is cleaner and easier on the system as opposed to mineral oils. Neither do they decompose easily, nor turn into black tar inside the pump. Also their low vapor pressure and low surface tension result in lower migration rate and low ‘creep’ phenomena inside the system. Users are saved from frequent opening and cleaning of the system, thereby saving time, money and effort. 5. Low Vacuum TimeSupervac’s single component silicone diffusion pump oils reach their maximum efficiency in a short time as they have high latent heat. This ensures a low vacuum time and cuts down the cycle time considerably. 6. Less Frequent Oil Replacement and Reduced DowntimeSupervac Industries’ ‘Sigma’ diffusion pump oils are extremely hardy, resistant to oxidation and hydrolysis and built to last. They do not deteriorate when exposed to air at operating temperatures. Therefore, time is saved between cycles as the operators need not wait for the oil to cool down before releasing the vacuum. 7. Chemically InertThese oils, being chemically inert, do not react either to the metal interiors of the pump like steel, copper, aluminum etc. or to the process gasses or elastomers.
8. Non-Flammable and non-toxic, therefore totally safe to use. 9. Very competitively priced.
