Applied in pump units and equipment where sealed fluids are oil products, liquefied hydrocarbon gases, liquids with harmful chemical agents.
The seals of the second variant of construction are more effective at the operation in the environments, prone to crystallization and polymerization, with a high content of abrasive substances as well as in high-viscosity products.
