AS SBB
Single end, multiple springs, balanced cartridge mechanical seal with spring protector and independent direction of rotation. Springs isolated from medium to prevent jamming from high viscosity and crystallization. Compensation components support the sleeve for extended lifetime. Easy installation without disassembling the seal cavity. Custom standards. Specifically designed for slurry pumps on the Tian Kun Hao dredger. Inner diameter range: 80–220 mm.
