HMT - Model Retro-Fit -Mechanical Shoe Seal for Aluminum Internal Floating Roofs
HMT’s Retro-Fit Mechanical Shoe Seal was designed to solve a common problem in the AST industry: how to add a primary mechanical shoe seal safely and effectively to an existing lightweight aluminum IFR. This seal employs a unique system of pontoons to provide additional buoyancy required at the perimeter and a compression ring to give the rim added strength and torque resistance to handle the drag forces exerted by the shoe seal. The Retro-Fit Mechanical Shoe Seal provides a long service life, compatibility with virtually all stored products, and a tight fit to aid in eliminating emissions losses.
With all the benefits of the HMT Mini-Shoe seal, this seal will outlast common floppy wiper seals multiple times over. This seal eliminates the problem of prematurely degrading wiper seals.

The Retro-Fit Mini-Shoe allows operators to improve not only the durability of their primary seal, but also improve the loss factor used in emissions calculations.
The Retro-Fit Mini-Shoe maintains a tight seal even with wide-ranging rim spaces and tank abnormalities
Workhorse design and materials
Supported by a system of buoyant pontoons — each pontoon is held in place by extruded structural aluminum framing for excellent strength and rigidity
