For seal type C and arrangement 3CW-FF, the bellows are made stationary and for this the drawings submitted is enclosed herewith. Is this arrangement is acceptable as the shaft sleeve have the pumping ring and the rotating seal faces are mounted . Thanks to clarify.

Looks good.

Also for the 53B bladder material (Nitrile Buna N) we were suggesting to use Therminol 66. Whether this material is suitable for this barrier fluid?

But I doubt the circulation of the barrier fluid. How far it will be effective?
The circulation path is quite long.

The problem with systems such as these is that there is so much metal in the seal chamber. So little room for the barrier fluid. But that is another discussion regarding seal chambers and pump design.
