Belzona® Solves Balance Problem On Impeller

 
 

Industry:

Oil & Gas (OILG)

 
 

Application:

Gaskets, Seals and Shims (GSS)

 
 

Customer Location:

ConocoPhillips Refinery, Wood River, IL

 
 

Application Date:

July 2007

 
 

Application Situation:

Impeller did not have a solid center bore. Instead, it had a boss fit on both sides with a 60 cubic inch void in the center.

 
 

Problem:

Liquid slowly entered the void during operation causing an imbalance and vibration.

 
 

Products:

Belzona® 1321 (Ceramic S-Metal)
 

Substrate:

Bronze

 
 

Application Method:

Belzona® 1321 was injected into the void, filling it completely. Application followed Belzona Know-How System Leaflet GSS-9

 
 

Belzona Facts:

Belzona® 1321 extensively used for injecting irregular shims. Product has good handling characteristics, is non-shrinking and has high mechanical strength. The pump needed to be back in production, a new impeller would take 6 month to be delivered, then, more of the same was likely to occur!
