7.11 Reassembly of pump
The following directions are for use when the pump is completely dismantled and it is desired to reas-
semble. See
4.3 Adjustment of stuffing box gland on page 26 .
1. If the impeller diameters have been cut in the field, the impellers should be statically balanced and,
if possible, dynamically balanced. Balancing can be effected by grinding on the outside of the
shrouds near the periphery.
2. Determine the correct setting of the impellers and sleeves on the shaft in relation to the rotation of
the pump. To do this, face the discharge flange of pump. The locking shaft sleeve (104) (sleeve with
keyway) must be on the right as shown in Figure 21 and the impellers must rotate in correct relation
to the casing as shown in the end views in Figure 21.
Figure 21:
3. Mark the location of the keyways on the outside of both the second stage impeller hub (145) and
the locking sleeve (104) at points "A" and "B" in Figure 22 and Figure 23. These marks will be used
later to indicate that the keyways are in line.
