A device and a plant for breeding fish, shellfish, etc. includes one or several tanks of a non-rigid material which are lowered into the water. Each tank has at least one inlet and at least one outlet for water. The inlet and the outlet are so arranged that the water level in the tank is somewhat above the surrounding level to maintain the walls of the tank in a tightened out position by the higher static pressure in the tank.

Device for breeding fish and shellfish

The rotatable seal ring of a mechanical seal is attached to a plain shaft by a grip ring and a housing that includes a disc spring. The rotatable seal ring is pressed against the non-rotatable ring by the disc spring, the compression of which is uniquely controlled by the depth of a recess formed in the housing to receive the grip ring.
