High-Performance Face-to-Back Arrangement Double Cartridge Mechanical Seal
Our Face-to-Back Arrangement Double Cartridge Mechanical Seal is designed to provide superior sealing performance in critical industrial applications. This high-performance seal is preassembled with a gland plate on a sleeve, enabling seamless installation over the pump shaft or shaft sleeve in conventional stuffing boxes, making it compatible with a wide range of pump types and manufacturers.
The Face-to-Back configuration combines the advantages of both back-to-back and face-to-face arrangements, ensuring efficient leakage control and an enhanced pressure barrier. This design is particularly suited for applications handling hazardous, toxic, or high-pressure media, preventing contamination and ensuring long-term equipment reliability.
For optimal operation, the seal must be installed at its correct operating length and positioned precisely within a clean housing. The cartridge construction allows for quick installation and easy removal, minimizing downtime and eliminating the need for highly skilled labour.
With its robust, factory-assembled design, our Face-to-Back Arrangement Double Cartridge Mechanical Seal delivers a highly efficient, durable, and maintenance-friendly sealing solution for demanding industrial environments.
