Cartridge seal

A Cartridge Mechanical Seal is a compact, pre-engineered sealing solution designed to eliminate leakage in rotating equipment such as pumps, agitators, and mixers. The seal is supplied as a fully assembled unit, integrating the seal faces, springs, secondary elastomers, sleeve, and gland into one precision-aligned cartridge, which ensures quick and error-free installation.

This type of seal works by maintaining controlled contact between a rotating seal face and a stationary seal face, supported by spring force and hydraulic pressure. The cartridge design protects critical sealing components from misalignment and shaft damage, making it highly reliable even in demanding operating conditions.
