Primary Mechanical Shoe Seal (MS6)

The Primary Mechanical Shoe Seal (MS6) has been used on different tanks types, containing the full range of Crude and Refined products. The seal is suitable for welded and riveted tanks with wide variations in rim spaces. All mechanical seal components are easily accessible allowing installation with the tank remaining “in-service”. No welding or flame cutting is required to install or maintain the shoes. All components are pinned or bolted with corrosion resistant fasteners.

Metallic shoes can be furnished in galvanized or stainless steel. Shoe height is selected to match the rim configuration, minimize extension below the floating roof and to ensure compliance with environmental codes. Metallic shoes are suspended in the rim space by bolt-on pantograph hanger assemblies. This flexible pantograph mechanism ensures that metallic shoes are held in constant contact with the tank shell despite rim gap variations.
