in api there are three arrangement
Arrangement 1: Seal configurations having one seal per cartridge assembly;
Arrangement 2: Seal configuration having two seals per cartridge assembly, with the space between the seals at a pressure less than the seal chamber pressure.
Arrangement 3: Seal configurations having two seals per cartridge assembly, utilizing an externally
supplied barrier fluid at a pressure greater than the seal chamber pressure.

Since you reference API, Appendix A of 682 would be the logical starting point.
