Pump deterioration leads to decreased pumping efficiency and eventually costly part replacement. Pitting, worn wear ring clearances as well as casing thin and through wall defects can be rebuilt using composites specifically designed for pumping applications. Pumping efficiency is restored and enhanced with the use of a hydrophobic smooth lining, which also protects from erosion-corrosion and cavitation. Once the pump has been protected with Belzona, it can remain maintenance-free for many years. Due to over 30 years’ experience in repairing and pumps, Belzona linings are now specified to protect new pumps, thus significantly extending the lifetime of the assets and subsequent maintenance-free periods. Belzona linings have become a first choice in protecting firewater pumps in particular, offering long-term corrosion protection and seizure prevention.
