*Product description:
Dual cartridge seal in compliance with standard API 682 4th edition in face-to-back version.
The balanced dual cartridge solution is ideal for arrangement 2 and 3 or with auxiliary
fluid at atmospheric pressure.
The two versions are particularly suitable for toxic or polluting fluids that crystallize when in
contact with the atmosphere or in case of no external washing; the rotary bellows prevents
