Elastomer Mechanical seals E12R

الاستومر مکانیکال سیل مدل E12R



  • 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 E12R 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 E12R 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. Installation proposals can be provided upon request.
