Rubber bellow type mechanical seal
Hydro Serve Technologies
Type HS25 has a unique rubber bellow secondary seal, which provides a high degree of axial flexibility to compensate for lack of concentricity of the shaft & misalignment & wear due to thrust movement of the shaft.
The seal can be use regardless of direction of rotation, since the driving torque is not transmitted through the coil spring, The required driving torque is enhanced through the unique rubber bellow which fits on the shaft. There are no bonded Joints and all the face materials are interchangeable without having to modify any dimensions.

Generally used in sewage applications, waste water pumps, & fuel injection pumps.
