Abstract
The fixed shaft housing (1) has a collar (2) holding a flexible concertina type bellows (3) made from synthetic material. The other end of this bellows is fixed to a location block (5), also of synthetic material, its end face having an annular recess, a hard carbon seal ring (7) fits in this recess. The shaft (6) passes through this assembly and has a rotating seal block (8), of stainless steel, fixed onto it by means of a screw (11) in one side. One end face (14) is in contact with the carbon ring, forming a joint. Inside this block are O ring seals (9, 10) held by an end plate (12, 13).
