Engineered Pump Solutions for High‑Temperature Thermal Systems
Molten salt applications place exceptionally high demands on pump technology. High operating temperatures, strong thermal cycling and continuous operation require robust, precisely engineered pump solutions to ensure safe, stable and efficient plant performance.
Rheinhütte Pumpen provides engineered pump solutions for molten salt systems, designed to operate reliably in high‑temperature thermal applications such as energy, chemical and industrial heat transfer processes.
Process Requirements and Challenges
Molten salts are used as high‑temperature heat‑transfer media and thermal energy storage systems, and are also employed for the heat treatment of metals in molten salt baths, typically operating within a temperature range of 150 °C to 600 °C.
From a pumping perspective, these applications involve:
- extreme operating temperatures
- thermal expansion and contraction
- fluctuating thermal loads during start‑up and shutdown
- strict requirements to maintain the salt in liquid state
- continuous 24/7 operation
These conditions require pump designs that go far beyond standard industrial solutions.
