Industry: Chemical
Location: Australia
Application: Split Case Pump Repair
Products: 101 Metal Repair Paste & 203 Super Flow
The Challenge
A split horizontal cast iron wastewater pump at a chemical plant suffered extensive pitting and wear from prolonged exposure to harsh process fluids. The damage significantly reduced performance and increased the risk of costly downtime. An urgent wastewater pump repair was needed to restore functionality, prevent further degradation, and ensure reliable operation in demanding conditions.
The Solution
The wastewater split case pump underwent an extensive cleaning process to remove contaminants and prepare the surface for repairs. This step was crucial to achieving a strong bond between the substrate and the repair materials. Pitted and damaged areas were meticulously restored using Resimac 101 Metal Repair Paste, which filled cavities and returned the pump to its original profile.
To ensure long term protection, the repaired pump was coated with two layers of Resimac 203 Super Flow. The first coat, applied in grey, formed a durable base layer to enhance the system’s resistance to harsh process fluids. The second coat, in blue, added an extra level of defence, particularly against abrasion and chemical attack. The dual layer system ensured comprehensive protection for the split case pump interior surfaces, reducing the risk of recurring damage and premature failure.
Results & Benefits
- Restored the OEM of the split case pump and provided a protective barrier to withstand the plant’s demanding chemical environment
- Reduced the risk of unforeseen failures, offering the facility confidence in its wastewater management system
- Improved performance and structural integrity of the pump
- Enhanced durability, lowering costs and maintenance requirements
