PI Operation Manual
The bearings should remain in their original packaging. Once they are to be
assembled onto the shaft, they must be removed from their packaging, and the preservative in
the outside diameter and the bore must be wiped out.
Bearings should be demagnetized before mounting them, to avoid contamination.
During assembly, all threads must be protected with an anti-seize agent.
1. Insert the shaft key in the keyway on the impeller side of the shaft.
In case that the pump is PI Fire or Close Coupled, the shaft must be assembled
with a shaft sleeve.
2. If applicable, insert the shaft sleeve into the shaft. Make sure that the sleeve enters completely.
