Vane material
Vane material
(OP)
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 material suggestions (max PV is 13,000).






RE: Vane material
can be used up to 200 degrees celcius.
If you use the compression moulding technique this material should be excellent for vanes. You can also use a virgin PTFE with a glass filling
RE: Vane material
If the application does not see moisture at elavated temperatures Torlon would be satisfactory. Please let me know if you need further info.
Good Luck
