Belzona® Restores Vacuum Pump Affected By Deep Erosion

 
 

Industry:

Mining and Quarrying (MINQ)

 
 

Application:

Centrifugal Pumps (CEP)

 
 

Customer Location:

Mine, Peru

 
 

Application Date:

April 2008

 
 

Application Situation:

Interior of the central casing of a large liquid ring vacuum pump

 
 

Problem:

Seal water drags solids deeply eroding the central body all around, on both sides of the central ribbing weakening the casing and even making a hole at one point.

 
 

Products:

Belzona 1311 (Ceramic R-Metal)

Belzona 1341 (Supermetalglide)

 

Substrate:

Cast iron

 
 

Application Method:

The application was carried out in accordance with the Belzona Know-How System Leaflet CEP-5. It was locally blasted and filled in using Belzona 1311 and was covered with Belzona 1341.

 
 

Belzona Facts:

For each hour that the plant is closed, the mine loses significant revenue. The delivery of a new casing would take too long. Using Belzona has saved production and the repair was completed in just 6 hours, during the plant’s general maintenance downtime planned for one day. Thanks to Belzona, the plant was never left without the vacuum pump.
