Extreme Temperature Rotary Seal
Extreme Temperature Rotary Seal
(OP)
Hi all,
I am looking for a sealing solution for isolating a pressurized air cavity (75 PSI) from the outside. A shaft is to come out of the cavity and it should be sealed to prevent the air from exiting. The rotation speed and duty cycle is low (10 RPM). The temperature of the cavity is high (1200 F) and it is the restriction for using the conventional seals. Please help me on selecting a product which can handle this situation.

No I have not think about that. It may seem very elementary question but it would help me a lot. can you please give me some hints on packing? Can it handle rotation or it is just for static sealing?

Do you have enough space oto mount a double seal.between inboard seal and vessel cavity long throat bush can be given to reduce temperature in seal area.
I suggest that please provide shaft diameter and axial space available.

Recommend to turn to specialized companies for the production of such seals: "SGL-Polycarbon", "SIGRAFLEX", "Union Carbide"(GRAFOIL).
