The seal contains fluoroplastic bellows of specific design, which can stand higher pressure. Support flange and rubber ring, which seal the shaft, are protected against sealed medium effect with the help of fluoroplastic covers. The outside cooling unit lowers buffer fluid temperature, improving seal operation conditions.
