Rubber Bellow Seals

Rubber Bellow Seals are mainly used in waste water treatment plants for the sewage applications.Due to its compact design it can be easily mounted.

It has a unique rubber bellow secondary seal, which provides a high degree of axial flexibiiity and protects the shaft/ sleeve from fretting.

Rubber Bellow Mechanical Seals can be used regardless of direction of rotation since the driving torque is not transmitted through the coil spring. The required driving torque is through the spring and spring holder.The single coil spring will avoid effluent particle.
