Belzona® Protects Paper Mill Fan Pump

 
 

Industry:

Fluid Flow (FLOW)

 
 

Application:

Centrifugal Pumps (CEP)

 
 

Customer Location:

Oregon, USA

 
 

Application Date:

2013

 
 

Application Situation:

Split case pump.

 
 

Problem:

Pumping stock at 125˚F, with calcium carbonate added, goes through a boil out process using sodium hydroxide and phosphoric acid at 165˚F. With the wear on the casing, it is just a matter of time before the chemicals create a hole.

 
 

Products:

Belzona 1111 (Super Metal)

Belzona 1391T

 

Substrate:

Cast Iron

 
 

Application Method:

The pump was grit blasted. Belzona 1111 was used to fill all the pitting. Two coats of 1391T were brushed on.

 
 

Belzona Facts:

There were no alternatives. Even a new pump would need to be coated to handle the caustic/acid boil out.
