Mechanical seals

Mechanical seal Type 380

The type 380 is a stationary single-cartridge seal. The mechanical seal was specially optimised to meet the requirements of the petroleum industry. The type 380 is equipped with a so-called "floating" safety seal. As a result, this mechanical seal is also recommended for extreme boundary conditions - from water and highly volatile hydrocarbons to acids and alkalis.
