Heat exchanger compliant with all requirements of API 682, 3rd and 4th edition. For single or double mechanical seals (arrangements 1, 2 or 3).
The heat exchanger cools the fluid upstream of the product-side mechanical seal and prevents vaporisation between the seal faces. This markedly increases the seal life.
Circulation between the cooler and the KSB mechanical seal is ensured via a circulation system integrated in the seal. A throttling bush largely isolates the cooled fluid in the seal chamber from the hot fluid pumped.
