Rubberbellow Seals

Elastomeric Bellows seals are non-directional, technically advantageous and extremely versatile.
Applications include, but are not limited to; Pumps, Mixers, Agitators and Compressors

Our range is vast and a seal to suit virtually all applications is available.

The design of the Bellows seals is such that all rotary components are contained with no loose parts that could
be subject to damage during fitting.

All bellows seals feature static sealing on the shaft that cannot cause shaft wear or fretting. Another advantage
of this design is that it can be used in situations where shaft fretting had previously occurred with another seal design.
