Roll Mill Slurry Pump Repair With Belzona

 
 

Industry:

General Industry (GIND)

 
 

Application:

Centrifugal Pumps (CEP)

 
 

Customer Location:

Steel Mill Decatur, Alabama

 
 

Application Date:

December 2005

 
 

Application Situation:

This is a large (5-foot diameter) slurry pump underneath the main floor of the roll mill. The slurry is comprised of wastewater and highly abrasive metal particles. The wear ring disintegrated allowing severe damage to the pump casing. The pump was taken to a machine shop and a stainless steel wear ring crafted.

 
 

Problem:

The wear ring disintegrated allowing severe damage to the pump casing. Their need was to repair the casing and find a way to bind the new wear ring in place. If this could not be done a new casing would have to be ordered.

 
 

Products:

Belzona® 1111 (Super Metal)

 

Substrate:

Pump casing is NiHard (nickle/chromium)

 
 

Application Method:

Application carried out in accordance with Belzona System Leaflet CEP-2.

 
 

Belzona Facts:

The pump casing was put back into service within a matter of days (within their shutdown period) instead of purchasing a new casing. Repairs costing a few thousand dollars in Belzona were better than a 6 week delay and 10s of thousands of dollars for a new casing. It has been 19 months and the pump is still in service and running well.
