Shaft seals for radiation environment
Shaft seals for radiation environment
(OP)
I am looking for shaft seals to be used in a gamma radiation environment. As I understand, perferred materials are EPDM and ethylene-acrylic (Vamac). None of the big seal manufactures seem to be able to help unless I purchase a production run. I have new design application and also need to retrofit purchased parts with acceptable seals (gearboxes etc.). Anybody else solved this problem?
Thanks.
Thanks.

I use these guys when I have special projects and a limited amount of seals required.
I think 5 minimum order is there low end and they are very reasonable.
Good Luck

RE: Shaft seals for radiation environment
So far in my search I've found the following useful info:
John Crane has cartridge type contact seals that may work (though the seal material may be affected by radiation and thus may require regular maintenance). If leakage is acceptable, a simple labyrinth seal may work (no maintenance is required for this type of seal). The labyrinth can be designed with a specific number of "lands" to control the leakage. Only problem is that the leakage may increase if the shaft is not in motion.
