Description

Rubber Bellows Mechanical Seals are designed with elastomer bellows as the dynamic sealing element. The rubber bellows compensates for shaft movement, misalignment and pressure variations while maintaining constant contact on the seal faces.

They are highly effective in sealing water, oils, mild chemicals and slurry applications where corrosion resistance and flexibility are essential.

These seals are cost-effective, easy to install and suitable for pumps, mixers and agitators across diverse industries.
