Engineered Pump Solutions for Safety‑Critical Chemical Processes
Chlor‑alkali electrolysis places exceptionally high demands on pump technology. The handling of highly corrosive and toxic media requires reliable, application‑specific pump solutions to ensure safe, stable and continuous plant operation.
Rheinhütte Pumpen provides engineered pump solutions for chlor‑alkali electrolysis, covering all industrial process technologies and supporting reliable operation throughout the entire process chain.
Process Requirements and Challenges
Chlor‑alkali electrolysis is the industrial basis for the production of:
- chlorine (Cl₂)
- caustic soda (NaOH)
- hydrogen (H₂)
On an industrial scale, two technologies are applied worldwide:
- diaphragm process
- membrane process
All three involve aggressive, corrosive and safety‑critical media, combined with strict purity requirements and continuous 24/7 operation. These conditions place extreme demands on pump design, materials and operational reliability.
