Mechanical seal Type 321
The DEPAC mechanical seal type 321 is a stationary, tandem-active, double-cartridge mechanical seal with a venting facility. The double pressure relief of the seal faces on the product side also ensures that the seal faces do not open in case of pressure reversal - and that the pressure relief for reducing the friction values is present under all pressure conditions. The product variants in the form of the type 322 and the type 323, which are intended especially for larger seal chamber cross sections, round off the universal range of application for this mechanical seal.
