Single Cartridge Seals
Compact, Pre-Assembled Cartridge Seals for Superior Sealing Performance
At GSI – Globe Seal Industries, we manufacture high-quality single cartridge seals designed to provide trouble-free sealing in pumps, mixers, agitators, and other rotating equipment. Engineered for easy installation and reliable operation, our cartridge seals help you reduce downtime, maintenance costs, and ensure consistent process integrity.
Product Overview
Single cartridge seals are pre-assembled, factory-tested mechanical seals housed in a convenient cartridge design. Unlike traditional component seals, cartridge seals integrate all critical elements — seal faces, secondary seals, gland, and sleeve — into a single, self-contained unit. This simplifies installation, improves alignment, and reduces the risk of seal failure due to improper fitting.
At GSI, our cartridge seals are designed to meet a wide range of service conditions, delivering dependable performance across many industries.
