Pump Oil Sump Not All Its "Cracked" Up To Be

 
 

Industry:

Water / Wastewater (WATR)

 
 

Application:

Valves, Pipes and Fittings (VPF)

 
 

Customer Location:

US Bureau of Reclamation / Farmington, NM

 
 

Application Date:

July 2007

 
 

Application Situation:

7000HP Lewis Alice Motor driving a water pump with 800 cubic feet per second flow rate

 
 

Problem:

Large oil sump for the shaft bearing at the top of the pump was experiencing cracking from harmonic vibration. As the company that produced the pump was no longer in business and available parts are difficult to find and very expensive, $1000 of Belzona saved them over $60,000 worth of replacement parts, labor and downtime. In addition the Belzona solution eliminated the problem from occurring again.

 
 

Products:

Belzona® 2111 (D&A Hi-Build Elastomer)
 

Substrate:

Steel

 
 

Application Method:

The application was carried out in accordance with a modified version of the Belzona Know-How System Leaflet VPF-3.

 
 

Belzona Facts:

Welding would have stressed the steel causing more cracks to appear. The only way to resist vibration and contain the oil was a flexible surface.
