The KGJ is a single-end, balanced cartridge mechanical seal designed for slurry pump applications. It features multiple springs, spring protection, and bidirectional rotation. The cartridge design allows quick and easy installation without disassembling the seal chamber.

The compensation components are supported by the sleeve to maintain stable axial movement. The springs remain isolated from the process medium, preventing clogging caused by high-viscosity media and crystallized solids. This design helps maintain the flexibility of the compensation ring and extends seal service life.

The KGJ is designed for abrasive, high-solid slurry applications. It is widely used in flue gas desulfurization (FGD) systems at coal-fired power plants. Typical applications include absorber slurry circulation pumps, gypsum slurry pumps, limestone slurry pumps, and gypsum discharge pumps.

The KGJ slurry pump seal is also suitable for slurry handling in paper making, alumina production, coal washing, mining, sewage treatment, metallurgy, power generation, and chemical processing.
