Maxwell MRS-3 Primary Spring Plate Shoe Seal (EFR Rim Seal)
Our Maxwell MRS-3 Primary Spring Plate Shoe Seal, also known as a “metallic shoe seal”, is characterized by a metallic overlapping sheet which are pushed by an integral compression spring to the tank wall. Having a gas-tight membrane hold in place by a membrane support makes this Spring Plate Seal very effective in reducing evaporation of emissions to nearly “zero” emission.
Our Maxwell MRS-3 Primary Spring Plate Shoe Seal is suitable for tanks without appreciable tank shell distortion or where the product stored is particularly aggressive. When using technical plastic shoe slider plates, this seal can be used in tanks where a tank shell coating has been applied.
The most commonly used Maxwell Mechanical Shoe Seals either used as a single or combined configuration are:
• MRS-1 Primary Mechanical Shoe Seal
The MRS-1 models can be combined with MRS-12 Secondary Shoe-Mounted Seal
All Maxwell MRS-3 Rim Seals can be combined with secondary rim seals
Finally, when the local requirements are pushing local terminals or refineries to add a tertiare or tertiary or triple rim seal, on request these extra rim seals can be provided by Maxwell.
