COLOSSUS CK800 Welded Metal Bellows Cartridge Seal (ANSI / DIN pumps)

Single, rotating welded metal bellows cartridge seal. Installation dimensions fit ANSI and DIN process pumps, in metric and inch sizes. The bellows uses a 45 degree inner forming angle to spread stress and raise pressure capability, and the face design was optimized by finite element analysis and validated by testing for low emissions. Available in standard and common material configurations.
