Rubber bellow mechanical seals are designed with the rubber bellows. Rubber provides the secondary seal between each seal face and adjacent seal face. One seal face is fixed and seals statically using an o-ring or cup gasket. The other is spring-loaded and requires a semi-dynamic seal to accommodate some axial play, such as a dynamic o-ring in pusher-type mechanical seal face seals or elastomeric bellows in non-pusher ones. The semi-dynamic applications(involving flexing and sliding of the elastomer)can be critical for maintaining proper contact between the faces through face friction, shaft movements, etc.
Wendong supplies a range of rubber bellows seals to suit a range of applications and media, from water and general liquids through to mildly aggressive and aggressive fluids. We offer rubber bellows mechanical seals in a variety of materials to suit different applications.
