Heat exchanger


  • Mode of operation to API Plan 23

Technical Data

  • Process side: Up to 50 bar: -29 °C to 270 °C
  • Cooling water side: Up to 20 bar: -29 °C to 100 °C


Tube-in-tube heat exchanger for cooling single and double mechanical seals.

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.
