We are designing a rotary vane pump that will be pumping pure oxygen. There is a concern about using carbon based materials from an ignition standpoint. With that in mind we are looking to use non-metallic vanes. The vane material is Torlon 4301 which is 12% graphite powder and 3% teflon. The vane loads are low and the Max operating temp is 160 deg F. Do you have any experience with this or comments? Any other sugestions on vane material (PV's = 13,000)
