Belzona 1111 (Super Metal)

Belzona 1341 (Supermetalglide)



Cast iron


Application Method:

Application was carried out in accordance with Belzona Know-How System leaflet CEP-10. Original profiles were restored with Belzona 1111 before applying two coats of Belzona 1341 to provide future erosion corrosion protection to the impellers.


Belzona Facts:

The application of Belzona 1111 restored the original surface profile, allowing the client to avoid the expense of a total part replacement. The Belzona 1341 then added a layer of protection, preventing the recurrence of cavitation or corrosion damage and simultaneously improving flow rates thanks to the smooth surface.
