Mechanical seals - TG Mechanical seals

TG GRAPHITE STEATITE + EPDM

General features

Rubber bellows mechanical seal
Unbalanced
Single spring
Independent of direction of rotation
Short axial installation length

Mechanical seal for large-series cold water pumps, produced in millions of units per year.
The TG owes its success to the wide range of application, the short axial length (this allows for more economic pump construction and saves material), and the best quality/price ratio.
The elasticity of the bellows design enables a more robust operation.
The TG can also be used as a multiple seal in tandem or back-to-back arrangement when the product media cannot ensure lubrication, or when sealing media with a higher solids content
