The TLJ is a single-end, balanced cartridge mechanical seal with multiple springs. It supports bidirectional rotation and uses clamp transmission.
The compensation components are assembled inside the seal flange. An elastomer barrier isolates the springs from the process medium. This design helps prevent spring jamming caused by slurry and solid particles.
Multiple springs distribute the closing force evenly across the seal faces. This arrangement helps maintain stable sealing performance during operation.
The sleeve uses elastomer support on the shaft. This design prevents axial displacement and helps protect the shaft from damage.
The cartridge construction simplifies installation and replacement. The seal also provides reliable performance in demanding slurry applications.
The TLJ is also known as an external-flush mechanical seal. It is widely used in power plant flue gas desulfurization, salt chemical processing, papermaking, and water treatment.
Typical applications include desulfurization pumps, salt slurry pumps, and paper pulp pumps.
