Products:

Belzona 1341 (Supermetalglide)

 

Substrate:

Steel and Brass

 
 

Application Method:

The application was carried out in accordance with the Belzona Know-How System Leaflets CEP-1 and CEP-3. Surface preparation was carried out by grit blasting to a near white finish. Belzona 1311 was applied by using a formed piece of applicator trimmed down to the same size and shape of the damaged volute area. Belzona 1341 was brush applied in two coats as recommended.

 
 

Belzona Facts:

The existing pump was only 5 years old and showing heavy cavitation damage. The pump casing would have been fairly expensive to replace. With maybe $5.00 USD of Belzona 1311 used to repair the damage and one unit of Belzona 1341 used to coat the impeller and the inside of the pump, it was a very cost effective repair. Additional benefits included an increase in the pump's efficiency when it was tested following reassembly.
