Description
The TR8S seal is particularly suitable, in the absence of external washing, for non-toxic and non-polluting fluids which crystallize in contact with the atmosphere; the rotating bellows excludes the problems of packing of the springs and the dynamic o-ring and tolerates axial and radial movements.
The balanced cartridge solution is equipped with a fixed containment bush for physiological leaks from the seal.
The TR8S seal is the result of the standardization of a series of projects tested and created in accordance with the API 682 IV edition standard.
- Balanced single cartridge seal, execution with rotating metal bellows and flange with fixed bush;
- The bellows allows double direction of rotation;
- Connections for washing and/or drainage;
- Flange and shaft sleeve designed to customer specifications;
- Solution developed to provide installations on existing machines;
- Recommended for ASME B73.1 and B72.2 horizontal and vertical pumps.
