CAUTION 

After installation of spare parts it is important that the steps outlined in Section 6.1 "Commissioning / Return to 
Service" are followed prior to start-up. 

 
Due to the erosive action of the slurry, many of the wet end components of the pump may require replacement during normal 
maintenance. Inspection or overhaul of the mechanical components may also require the replacement of certain parts. 
 
The following are recommended lists of parts (whenever applicable) to have on hand for normal maintenance and inspection. 
The  quantities  of  parts  kept  in  store  will  depend  upon  the  severity  of  the  slurry  duty  and  the  number  of  units  operating. 
Maintenance practices may also favor keeping fully built sub-assemblies or complete pumps on hand in some cases. Previous 
experience in similar duties often provides the best experience. If in doubt, contact your GIW / KSB representative for specific 
recommendations.
