description abstract	Practice: Oil-free pumping is the latest state of art in vacuum pump technology. At Kennedy Space Center, this technology is used to maintain approximate 650 sections of the LOX/LH2 vacuum jacketed transfer lines, at a pressure between 0-1000 Torr. This insures the capability to deliver cryogenic propellants on time and at a pre-defined temperature and pressure to the Shuttle vehicle. The use of oil-free pumps eliminates the risk of contaminating the LOX/LH2 transfer system (vacuum jacketed lines). It enhances the reliability of the vacuum pumping system.
