COLOSSUS C8 Multi-Spring Mechanical Seal (DIN 24960)

Multi-spring rotating mechanical seal with an integrated seal ring design. Connection dimensions comply with DIN 24960 and GB 6556, so it fits standard centrifugal pumps and other rotating shaft equipment. The compact design resists pressure and thermal deformation and keeps face distortion low at high pressure. Variants C8U, C8UV, C8B, C8BV and C8BKC cover different working conditions.

Key features
