COLOSSUS CK300 Multi-Spring Cartridge Mechanical Seal (ANSI / DIN pumps)

Balanced cartridge seal with external multiple springs. Installation dimensions fit ANSI and DIN process pumps, in metric and inch sizes. The rotating face design was optimized by finite element analysis and validated by testing for low face emissions, and a reverse balance structure withstands short back pressure. Wide choice of materials.

Key features

• Cartridge design: removes installation errors
• Fits ANSI and DIN process pump seal chambers, metric and inch series
• Quick positioning pin drive
• Reverse balance: withstands momentary back pressure
