Pantograph Type

Due to the force exerted by the weights, the pressure at the top and bottom of the mechanical seal is optimized. The weighted structure, along with the use of materials thinner than carbon steel and aluminum, eliminates the need for extra weight. As a result, the system effectively minimizes product leakage by using the pressure generated by the springs, in contrast to the weighted system. The efficient sealing performance can accommodate gaps up to 200 mm and operates within a ±100 mm tolerance range.

Design Features

Each seal is customized to fit the tank to ensure maximum performance, long life, and safe operation. Primary seals include a variety of configuration and component options. 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 (made of Teflon) 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. Storagetech Liquid mounted Primary shoe seals can be categorized as PANTOGRAPH and SCISSOR type seals. The most important issue that affects the performance of the sealing system is that the load which is applied to the shoe seals needs to balance and this force covers all openings through the rim. Mechanical seal systems are restricted to the lined storage tanks for not to damage the cladding material.
