Engineered Pump Solutions for Corrosive Pickling Processes
Steel and stainless steel pickling places exceptionally high demands on pump technology. Aggressive pickling acids, metallic ions, solids and continuous operation require reliable, application‑specific pump solutions to ensure safe, efficient and stable plant operation.
Rheinhütte Pumpen provides engineered pump solutions for steel and stainless steel pickling applications, supporting all stages of the pickling and regeneration process under highly corrosive conditions.
Process Requirements and Challenges
Pickling processes are used to remove surface layers such as scale, rust and oxides by chemical or electrochemical treatment. During operation, pickling solutions become increasingly loaded with:
- metallic ions
- solid particles
- reaction by‑products
As a result, pickling liquids must be renewed, solids must be separated or the media must be recycled. From a pumping perspective, these processes involve:
- highly corrosive acids
- solids‑laden fluids
- fluctuating chemical compositions
- continuous operation in harsh environments
These conditions exceed the limits of standard pump designs and materials.
Engineered Pump Solutions for Pickling Applications
Rheinhütte Pumpen develops application‑specific pump solutions for the handling, circulation and treatment of pickling liquids in steel and stainless steel processing plants.
Pumps are designed to handle:
- highly corrosive pickling media
- suspended solids and metal salts
- regeneration and recycling circuits
Each solution is precisely adapted to the specific medium, concentration and operating conditions.
Material and Design Expertise
A key success factor in pickling applications is the correct selection of corrosion‑resistant materials.
Rheinhütte Pumpen offers a broad portfolio of suitable materials, including:
- polypropylene (PP) and polyethylene (PE) for many common pickling media
- advanced plastics such as PVDF and PFA / PTFE for more aggressive conditions
- special materials such as SIGUSS® and high‑alloy stainless steels (e.g. 1.4517) for demanding applications
Based on decades of practical experience and in‑house expertise, Rheinhütte Pumpen selects the optimal pump material even for complex and difficult pickling media.
