Hydro Runner at a small Canadian Power Plant
Mild cavitation was decreasing generating efficiency
Runner was coated with Belzona 2141 (ACR-Fluid Elastomer) to restore and maintain efficiency. After 2 years it is still in perfect condition.
ITT 3480 Impeller
Severe cavitation was necessitating a full rebuild every 3 months
Impeller received two coats of Belzona 1321 (Ceramic S-Metal) and a final coat of Belzona 2141 (ACR-Fluid Elastomer). Impeller now lasts 28 months between rebuilds!
