Dual Cartridge Seals

As single cartridge catalog seals, Dual cartridge catalog seals are also designed for specific or general purpose applications with emphasis on best forgiveness for extreme operating environment. They fit standard or oversized seal chambers of process pumps per ANSI/ASME B73 specification or equal.

Dual seals are required when single seals cannot survive the operating conditions or cannot meet environmental emission regulations.
