TAC 11 Cartridge Seal

 

The TAC-11 is a full cartridge design. It is a single stationary multi-spring seal with an elliptical gland. It is a great replacement for two-bolt gland & packing configurations and component seal applications. Many consider this seal to be the next step up from two-bolt gland & packing configurations and component seals. All of AR Thomson Groups ANSI mechanical seals are balanced seals and feature monolithic faces, thermal management technology, and stationary spring designs. Monolithic faces have proven to be more resistant to distortion from higher temperature or pressure applications.

 

Thomson Adaptive Cartridge Thermal Management Technology

The thermal management technology removes heat from the faces and distributes it to other areas of the seal and stuffing box. This removal of the heat allows for some intermittent flow of liquid between the faces (dry running). Stationary spring designs are self-aligning and allow for some alignment issues and improper installation.

 

The TAC-11 design is excellent for process pumps, clean to light slurry, water/wastewater, and irrigation systems. The seal is lightweight and physically smaller in order to fit in many applications that a larger seal may not. This seal may also be a good candidate for applications where flush media may not be present or there is no room for the flush line. It is available in many different metallurgies, elastomers, and face combinations to meet the specifications of your application.
