Safematic SE2-LSTB-3.150-QRMG-303822 Mechanical Seal is a dual, cartridge-type SE2 seal built for Sulzer and Andritz paper-and-pulp pumps. The model SE2-LSTB-3.150-QRMG-303822 belongs to Safematic’s SE2 family, a dual, balanced cartridge seal designed for the demanding service found in pulp-and-paper equipment and slurry pumps. As a replaceable dual-seal solution, it integrates the seal faces, springs, and gaskets into a single cartridge, enabling straightforward service without disassembling the pump itself. Industry references describe the SE2 line as an option for replacing Sulzer or Andritz seals on paper and pulp machines, supporting reliable operation in challenging fluids and high-wear environments. Typical applications include Sulzer/Andritz pumps used in pulp processing and related industrial processing where a compact, robust dual cartridge seal is advantageous.
