Impeller assembly
1. Place the impeller key(s) in the shaft key slot.
2. Apply anti-seizing agent along the entirety of the shaft length.
3. Place the impeller on V-blocks or stands such that the impeller bore direction is
parallel to the ground. The shaft will be horizontally inserted into the impeller bore.
4. Check the impeller and casing to determine the correct rotational relationship. Insert
the outboard (non-driving end) of the shaft into the impeller bore horizontally using a
rubber mallet to gently tap the shaft in until the impeller is centered along the impeller
key length.
5. Lightly grease casing wear ring O-rings and roll them into their respective grooves.
Insert two steel pins into each casing wear ring. Slide the casing wear rings over the
impeller eye.
