Customer Location:

Austria

 
 

Application Date:

Application Situation:

In the course of a general refurbishment and performance increase of the pump, a new impeller was installed which changed the profile. This required a change in the contour of the shaft, which is where Belzona was required. The areas of the shaft in contact with water were coated with Belzona 5811.
