  GMN - Labyrinth & Gap Seals  

The GMN Non-Contact Seals are the right alternative for customer designed labyrinth seals which are expensive and difficult to produce. Our products are effective but not expensive due to the compact design and easy installation for the most applications. They are working properly independent of inner or outer ring rotation or of both parts turn.

Non-Contact Seals may be used as an alternative even to contact or rubber seals, especially at higher speeds. Fine or coarse granular contamination as well as splashing liquids can be sealed reliably. There are quite some applications where a Non-Contact seal may be used as the first step of a complex sealing system when a contact seal is required but has to be protected against granular or dusty environment to increase the life of the whole unit or seal assembly.


Labyrinth Seals

The GMN Labyrinth Seals are made from steel and aluminium. Due to the very special production process we gain absolute identity and smooth use of the profiles of inner and outer ring, resulting in optimum sealing performance. The Labyrinth Seals are supplied as complete, not separable units of a steel inner ring and an aluminium outer ring with no contact after proper installation.

    Gap Seals

The GMN Gap Seals with return drain are made from high quality and highly resistance plastic material. The chemical resistance covers lots of chemicals, bacteria and fungi. This fact is highly appreciated by the food industry and the consumer goods industry.
