8) The rotor should be disassembled only
in a shop environment. The impellers
are interference fit on the PWM models,
and are not designed to be removed in
the field.
9) The reinstallation of the rotor should be
performed in reverse order of the above
steps. The case ring locking pins should
all be turned to the top for installation,
and rolled into the locking slot once the
element is landed in the casing. If this is
a replacement element, the rotating
element will need to be checked for
centering in the stationary wear parts
and volutes, and checked for TIR.
10) To set centering, use a magnetic base
dial indicator on one end of the pump,
and set the indicator parallel to the shaft
axis. Using a screw driver or small pry
bar between an impeller and the shroud
wall, carefully push the element all the
way toward the dial indicator. Set the
indicator to “0”. Carefully push the
element in the opposite direction and
record the total distance. Care should
be taken not to damage the case split
line or impeller when pushing the
element. The centering setting should
be half of the total travel of the indicator
when the centering shim and thrust
bearing are installed. Adjust centering
shim thickness as necessary to set the
proper centering.
