Overview
Erosion-corrosion and cavitation reshape pump impeller vanes and shroud profiles, pulling the unit away from its rated head curve and dropping efficiency by 5 to 10 percent before bearing temperature signals a problem. Belzona 1311 (Ceramic R-Metal) rebuilds the eroded vane geometry; Belzona 1111 (Super Metal) addresses metal loss on shaft sleeves, wear rings, and impeller hub interfaces where dimensional accuracy matters. Both rebuild on the bench with no welding, no balance disturbance from heat-affected zones, and a dry-film thickness controllable to the original profile.

About Pumps
Cavitation pitting on impellers, abrasive wear on volute liners, and corrosion of pump casings drive most pump downtime in industrial service. Belzona repair composites and coatings let plants restore lost wall thickness and add an erosion-resistant finish without removing the pump from foundation.
