When industrial equipment suffers from severe corrosion, the traditional route of replacing assets is costly and involves extended downtime. Belzona UK can help rebuild your vital assets and increase asset life.
How can a pump be rebuilt instead of replaced?
A pump in continuous industrial service was suffering from severe corrosion. The condition had deteriorated to the point of significant through-wall defects, raising urgent concerns about safety, performance, and operational continuity.
Due to the pumps importance to the facility’s process, any extended outage to replace was out of the question. Belzona UK offered a solution to refurbish the pump and have it reinstated within days.
Rebuilding pumps with minimal downtime
The Belzona UK team designed a composite and coating solution that addressed both the structural and protective needs of the pump:
1. Structural Reinforcement with Belzona 1981 SuperWrap II
The pump’s damaged areas were structurally rebuilt using Belzona 1981 SuperWrap II, an ISO 24817 and ASME PCC-2 compliant composite repair system. Belzona 9371 reinforcement sheet was integrated to restore strength and integrity to the severely weakened structure, providing reinforcement.
2. Surface Profiling with Belzona 1311 (Ceramic R-Metal)
Once structurally sound, the team skimmed the repaired surfaces with Belzona 1311, a high-performance rebuilding compound. This step restored the pump’s internal geometry, improving flow efficiency and creating a smooth profile ready for protective coating.
3. Long-Term Protection with Belzona 1391T (Ceramic HT)
Finally, the application team coated the surface with Belzona 1391T, a high-temperature, corrosion- and chemical-resistant coating. This solution provides long-term protection against the erosive and corrosive conditions.
How to rebuild and enhance a pump with Belzona
Benefits of pump restoration
Belzona UK successfully restored to full service within days, minimising downtime and saving on significant costs. The multi-step repair reinstated mechanical strength and ensured long-term corrosion protection, ensuring safe operation.
Since reinstating the asset, the plant has reduced power to the pump as the repair was so successful it is now outperforming the other pumps in-situ.
Why It Worked
- Cold-applied, no hot work, reduced safety risks during repair
- ISO & ASME compliant composite system guarantees performance
- Restoration & protection, extends the equipment’s operational lifespan
- Minimal disruption & carried out in situ, avoiding costly replacement
This project is a prime example of how our engineered polymer systems give failing assets a new lease of life, even in the most severe cases of corrosion damage.

Warning signs include reduced flow or pressure, unusual noise or vibration, leaks, overheating, increased energy consumption, or visible corrosion on the pump casing or impeller.
Repair times depend on the severity of damage and the cure time of the materials used. Many cold-applied repair systems cure quickly, allowing pumps to be returned to service within hours instead of days.
Casing, volutes, wear rings, impellers, shaft sleeves, flange faces, and suction/discharge areas can often be rebuilt or protected. Surface deterioration caused by corrosion and erosion is commonly restored.
