Having a unique Rubber Bellow secondary seal, these seals have been designed for general sealing purposes. The unique rubber bellow seal provides high degree of axial flexibility to compensate for misalignment, lack of concentricity of the shaft and wear due to thrust movement of the shaft.
As there is no relative movement between rubber bellow and shaft, there is no fretting and seal can react quickly to any movement.
Another type of Rubber Bellow seals is with outer spring. It drives the seal and secures face contact in both directions. These seals are used slurries, sewage and waste water applications.
This seal is generally used in hot & cold water pumps, oil pumps including others.
