Industrial Pump Repair: Power Generation, Italy

6th November 2024

Industry: Power Generation
Location: Italy
Application: Industrial Seawater Pump
Products: 201 Ceramic Repair Paste & 202 Ceramic Repair Fluid

The Challenge

At power plant in Italy, the casing of a recycling seawater pump exhibited extensive corrosion and pitting due to prolonged exposure to harsh marine conditions. This damage threatened the pump’s operational efficiency and reliability, emphasising the need for a robust industrial pump repair solution to restore functionality and prevent further degradation. The customer sought a long term repair method capable of withstanding the plant’s demanding environment and ensuring consistent performance.

The Solution

The pump casing was prepared through abrasive blasting to ISO 8501/4 SA 2.5 (SSPC SP10/NACE 2) standards, achieving a 75-micron angular profile to optimise coating adhesion. After blasting, MEK was used to clean and degrease the surface, ensuring no contaminants remained. Pitted areas and corrosion holes were meticulously repaired using 201 Ceramic Repair Paste, restoring structural integrity and creating a solid foundation for the protective coating.

Two coats of 202 Ceramic Repair Fluid were applied using brush techniques to ensure complete coverage. Each layer was applied at a nominal thickness of 350 microns, forming a durable, erosion resistant barrier. This multi-layered system provided enhanced protection against the abrasive and corrosive effects of seawater, extending the pump’s operational lifespan under demanding conditions.
