This Seal is designed with a wave spring for media containing solids or with high viscosity, e.g., sugar, paper, sewage and wastewater industry. This seal can also be used in a dirty application, as spring clogging does not occur. The springs are product-protected. There is no sticking or clogging; keep faces in contact. Additionally, these series are compact in design, featuring a reduced axial length. Torque transmission from the retainer shell to the seal ring is through the drive pin.
