Belzona® Reconstructs Turbine Blades And Impeller

 
 

Industry:

Mining and Quarrying (MINQ)

 
 

Application:

Centrifugal Pumps (CEP)

 
 

Customer Location:

Mine, Chile

 
 

Application Date:

July 2010

 
 

Application Situation:

Required coating for the impeller to protect it against severe abrasion.

 
 

Problem:

The worn-out turbine blades prevented the equipment from working properly. 

 
 

Products:

Belzona 1311 (Ceramic R-Metal)

 

Substrate:

Steel

 
 

Application Method:

The impeller was cleaned and the turbine blades were repaired to its original dimensions. In order to achieve this, bars were welded to define the area and provide support. Then, a wire mesh was placed with the goal to strengthen the repair and define the body of the turbine blades, in order to later apply Belzona 1311. Application was carried out in accordance with a modified version of Belzona Know-How System Leaflet CEP-1.

 
 

Belzona Facts:

The customer did not have an additional impeller at that time and the equipment had to remain in operation. For this reason the impeller was repaired without stopping the machine until the new equipment arrived the following week. Since the impeller that was repaired with Belzona 1311 was working well, it was replaced only after six months.
