Description
The TRHS 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 seal equipped with secondary graphoil gaskets is recommended for fluids with temperatures higher than 260° C.
The balanced cartridge solution is equipped with a floating containment bush for physiological losses of the seal.
The TRHS 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, rotating metal bellows and flange with floating bush
- Connections for flushing and quench hole with steam and labyrinth device to force the circulation of steam to touch and completely cool the seal and sliding surfaces
- Double direction of rotation
- Mutipoint injection uniform flow distribution system
- Flange and shaft sleeve designed to customer specifications
- Recommended for API 610 horizontal and vertical pumps
- Solution developed to provide installations on existing machines.
