Cartridge Mechanical Seal

Single Cartridge Unbalance Mechanical Seals

A Cartridge seal is a design with complete installation on site with no requirement of trchnical experts . A cartridge seal design should be used whenever possible to ensure proper seal assembly and optimum mechanical seal MTBFs. The use of cartridge mechanical seals significantly minimizes installation errors.

This seals are single acting pre-assembled cartridge mechanical seals, which could be directly installed without any dimensional adjustment during installation. These cartridge unbalanced seals are independent of direction of rotation being designed to handle slurries, sludge, thick syrup and polymerising fluids. The spring provided in the cartridge construction are being isolated from the fluid enhancing the seal life.
