HMT - Model Allentech -Primary Mechanical Shoe Seal
The primary mechanical shoe seal is considered a liquid mounted seal per API and EPA recommendations. The tightly spaced hoop springs exert a nearly constant force against the tank shell to maintain the seal even around peaked vertical seams and abrupt tank distortions. We have completed thousands of installations throughout the world and have eliminated seal compatibility and replacement issues for AST operators since 1992.
High Durability
Long life due to the use of type 301 full-hard stainless steel pressure mechanisms.
Lightweight
Designed especially for Aluminum Internal Floating Roofs.
Excellent Compatibility
Stainless Steel and PTFE components are compatible with virtually all stored products.
Even Pressure / Gap Sealing
Equal force is applied to the Shoe Plate through the continual contact of the hoop springs.
Threaded S.S. studs welded directly to the shoes
No through holes that promote corrosion and increase shell friction.
