TR8D

Description

The TR8T/D seal is particularly suitable, in the absence of external washing, for toxic or 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 “dual” cartridge solution is suitable for execution 2 and 3 or with auxiliary liquid at atmospheric pressure (buffer) or pressurized (barrier).

The TR8T/D 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 cartridge seal, execution with rotating metal bellows;
  
• Double direction of rotation;
  
• IN-OUT flushing or vent connections for auxiliary liquid;
  
• Auxiliary liquid circulation device with high capacity to dissipate heat and avoids the need for an external pump;
  
• Recommended for ASME B73.1 and B72.2 horizontal and vertical pumps;
  
• Solution developed to provide installations on existing machines.
