Primary and Secondary Seal Systems for Internal Floating Roof Tanks and External Floating Roof Tanks. We Design, Manufacture and Supervise the Installation of a range of Seal Systems for Floating Roofs. There are three possible mechanical seal systems that we would recommend for most External Floating Roof Tanks:- TS1 - Mechanical Pantograph Shoe Plate Primary Seal together with Compression Plate Secondary Seal This is a very robust seal system with excellent efficiency and long operating life. To install the TS1, access is required from the underside of the floating roof. It also requires the addition of a Secondary Seal (TS16/2) TS100 - Mechanical Lightweight Primary Seal together with Compression Plate Secondary Seal A primary seal system with excellent efficiency and long operating life. The seal can be installed and maintained from the top of the roof and therefore access is not required from the underside of the floating roof. This means it is not necessary to take the tank out of service for major seal repair/replacement. It also requires the addition of a Secondary Seal (TS16/2) TS16 - Mechanical Double Compression Plate Seal This is the most cost effective and efficient seal system available – in fact LM TankServ guarantee 12 years zero maintenance required when the tank is operating normally. This seal can be installed and maintained from the top of the roof and therefore access is not required from the underside of the floating roof and it is not necessary to take the tank out of service for major seal repair/replacement. A further advantage is that a separate Secondary Seal is not required as it is already incorporated.
