Reliable Pump Technology for Highly Corrosive Process Media
Sulphuric acid production places exceptionally high demands on pump technology. Highly corrosive fluids, in some cases containing abrasive solids, varying temperatures and continuous operation require robust, application‑specific pump solutions to ensure safe and reliable plant performance.
Rheinhütte Pumpen provides engineered pump solutions for sulphuric acid production, designed to operate reliably under the harsh chemical and mechanical conditions typical of this process and to support stable operation across all production stages.
Process Requirements and Challenges
In sulphuric acid plants, pumps are required to handle:
- liquid sulphur
- dilute and concentrated sulphuric acid
- Spent sulphuric acid with impurities for reconcentration
- Oleum
- Reconcentration of spent sulphuric acid (weak acid)
- Processes with fluctuating temperatures and thermal loads
These conditions lead to severe corrosion, erosion, abrasion, and thermal stress, and they quickly exceed the limits of standardized pump materials and designs.
Engineered Pump Solutions for Sulphuric Acid Applications
Rheinhütte Pumpen designs application‑specific pump solutions for all critical process steps in sulphuric acid production.
Depending on the duty, vertical and horizontal centrifugal pumps are used and precisely adapted to the chemical composition, temperature and solids content of the media.
Optimized hydraulic designs and robust mechanical constructions ensure stable performance, high operational safety and long service life, even under continuous operation and aggressive process conditions.
Material and Design Expertise
A key factor for reliable pump operation is the careful selection of corrosion‑ and wear‑resistant materials.
Rheinhütte Pumpen offers a broad portfolio of special alloys and corrosion‑resistant materials specifically developed for sulphuric acid applications. These materials provide long‑term protection against chemical attack and mechanical wear and significantly reduce maintenance requirements.
Through close cooperation with leading plant constructors and supported by in‑house research and development, Rheinhütte Pumpen continuously adapts its materials and designs to changing process conditions and evolving plant concepts.
