KTL External Flush Mechanical Seal for Desulfurization, Salt Slurry and Pulp Pumps

KTL is a balanced cartridge mechanical seal designed for desulfurization, salt slurry, paper pulp, and water treatment pumps. Its multiple-spring design provides even load distribution, while the elastomer-isolated springs help prevent clogging and sticking. The stationary design supports bidirectional rotation and enables easy installation with reliable sealing performance.

The KTL is a single-end, balanced cartridge mechanical seal with multiple springs and a stationary design. It supports bidirectional rotation and uses a clamped drive for reliable torque transmission.

The compensation assembly is integrated into the flange. An elastomer isolates the springs from the process medium, helping prevent spring clogging and sticking. Multiple springs distribute the closing load evenly across the seal faces. This design helps maintain stable sealing performance during operation.

The sleeve is supported by elastomers on the shaft. This structure prevents axial movement and helps protect the shaft from damage. The cartridge design also simplifies installation and maintenance.

The KTL is also known as an external flush mechanical seal. It is designed for demanding applications involving abrasive or corrosive process media.

The KTL mechanical seal is widely used in power plant flue gas desulfurization, salt chemical processing, paper making, and water treatment. Typical applications include desulfurization pumps, salt slurry pumps, and paper pulp pumps.
