Mechanical seals
Mechanical seals from ttv - for compressors, pumps, apparatus and machinery

Mechanical seals can only achieve their necessary sealing function and service life if important functional requirements are met. These requirements include the plane-parallelism of the sealing faces, the perpendicular positioning of the sealing faces to the rotation axis, the resilient contact between the sealing faces and a lubricating film between the two sealing faces of the mechanical seals. The sealing effect between the mechanical seals and other components such as housings or shafts is usually created using additional seals such as O-rings and gaskets.

When developing compressors, pumps and other equipment and machines, engineers need to prevent the escape of liquids or gases on a consistent basis. And it’s in this area where the impressive strengths of ttv mechanical seals really become clear.
