Main features makes Zwick TRI-CON popular in many severe application in industries
Self-Centering Disc:
The construction guarantees the optimal position of the laminated seal against the seat. Jamming due to thermal expansion is eliminated.
Torque Transmission using keys:
The disc is keyed to the shaft not pinned, providing balanced torque transmission and eliminating the danger of pins shearing off.
Ideal lamination and disc design:
The strong disc with its eliptical supporting surface offers the best fixing of the lamination. Bubble tightness is given as a result of the special machining of the lamination.
Supporting bearing bushes :
The optimal position of the bearing reduces the risk of the shaft bending. This guarantees bi-directional tightness at maximum differental pressure.
