Perfo – P1000 Primary Mechanical Scissors Shoe Seal

Our ATT Tank Perfo – P1000 Primary Mechanical-Shoe Seal, also known as a “metallic shoe seal”, is characterized by a metallic sheet (the “shoe”) that is held against the vertical tank wall. The mechanical shoe seal height is 750 millimeters (mm). The shoe is connected by braces to the floating deck and is held tightly against the wall by springs or weighted levers. A flexible coated fabric (the “envelope”) is suspended from the shoe seal to the floating deck to form a vapor barrier over the annular space between the deck and the primary seal.

Our ATT Tank Perfo – P1000 Primary Mechanical-Shoe Seal is suitable for tanks without appreciable tank shell distortion or where the product stored is particularly aggressive. Unsuitable for distorted tanks shells or where shell coatings have been applied.
The ATT Tank Perfo – P1000 Primary can become equipped with counterweights or with a coil spring or pusher bar system as the sealing pressure is more constant over time.
