Application Situation
6 Centrifugal Pump Impellers at an O&M company. 
Application Method
The application was carried out in accordance with a modified version of Belzona Know-How System Leaflet CEP-1, after thorough surface preparation and cleaning, the damaged parts of the impeller were rebuilt with Belzona 1311. Then Belzona 1341 was used to provide protection before Belzona 2141 was applied to protect from cavitation.
