To support gas sealed Mechanical Seals with Nitrogen, other technical gases or gas mixtures, in many cases a high gas flow is required.
Depending on the required flow capacities we have been working with the DLE5 or the 8DLE1,65 in many different projects. Due to the different specifications regarding Temperature, Working pressure, the approved materials and standards (i.e. NACE) a range of different variants is available.
The following table will give an overview about the different variants, which are suitable for most of the seal gas applications.
