Package includes a set of tightly attached independent units of: a seal, bearing, bellow, cooling unit. Fluoroplastic bellows of specific design can stand higher pressure. Parts, interacting with working medium, are protected with fluoroplastic covers. Silicon carbide or silicized carbon seal faces are applied. The cooling unit allows using seal at working medium temperatures up to +300°С, reducing temperature in sealed area.
