Rubber Bellows Mechanical Seal WM104

Rubber Bellows Mechanical Seal WM104 is identified by the use of a unique elastomer bellows or diaphragm for the secondary sealing part, which provides a high degree of axial flexibility to compensate for lack of concentration of the shaft & misalignment & wear due to thrust movement of the shaft. Rubber Bellows Mechanical Seal WM104 is the most common and generally used rubber bellow seal, due to its compact design, easy installation, mass production, and low cost.
