The Mechanical Shoe Seal is the most efficient option on the market for internal floating roof primary seals. Featuring robust, all stainless-steel components, this seal provides effective, tight shoe fit at both small and large annular rim gaps with a long and reliable service life. Additionally, this seal can be easily and safely installed during either in-service or out-of-service periods and is suitable for almost any internal floating roof style and configuration.
The DirecTank Inner Shoe shoe support mechanism consists of a durable uni-pivot hinge configuration with sufficient structural rigidity to support the shoe plate during travel within rim spaces. The shoe plate is kept in constant, tight contact with the tank shell by complementary compression elements consisting of hardened spring steel. These components allow for reliable performance in even the most challenging operational conditions, including small annular rim space and tank shell inconsistencies.
This mechanical shoe seal is the most versatile, robust primary seal option on the market providing long, reliable operation and efficiency.
