Xylem 9100 Series Base Mounted Centrifugal Fire Pumps AC8585 REV.C - Manual (Page 9)

10. GROUTING PROCEDURE
Grout compensates for uneven foundation,
distributes weight of unit, and prevents
shifting. Use an approved, non-shrinking
grout, after setting and leveling unit (See
Figure 5).
a. Build strong form around the foundation to
contain grout.
b. Soak top of concrete foundation
thoroughly, then remove surface water.

c. Base plate should be completely filled with
grout.
d. After the grout has thoroughly hardened,
check the foundation bolts and tighten if
necessary.
e. Check the alignment after the foundation
bolts are tightened.
f. Approximately 14 days after the grout has
been poured or when the grout has
thoroughly dried, apply an oil base paint to
the exposed edges of the grout to prevent
air and moisture from coming in contact
with the grout.

12. ALIGNMENT PROCEDURE
NOTE: A flexible coupling will only
compensate for small amounts of
misalignment. Permissible misalignment will
vary with the make of coupling. Consult
coupling manufacturer’s data when in doubt.
Allowances are to be made for thermal
expansion during cold alignment, so that the
coupling will be aligned at operating
temperature. In all cases, a coupling must be
in alignment for continuous operation. Even
though the coupling may be lubricated,
misalignment causes excessive wear,
vibration, and bearing loads that result in
premature bearing failure and ultimate seizing
of the pump. Misalignment can be angular,
parallel, or a combination of these, and in the
horizontal and vertical planes. Final alignment
should be made by moving and shimming the
motor on the base plate, until the coupling
hubs are within the recommended tolerances
measured in total run-out. All measurements
should be taken with the pump and motor foot
bolts tightened. The shaft of sleeve bearing
motors should be in the center of its
mechanical float.
NOTE: Proper alignment is essential for
correct pump operation. This should be
performed after base plate has been properly
set and grout has dried thoroughly according
to instructions. Final alignment should be
made by shimming driver only. Alignment
should be made at operating temperatures.
WARNING: Unexpected Start-up Hazard
Disconnect and lock out power before
servicing. Failure to follow these instructions could
result in serious personal injury or death and
property damage.

REMOVAL/INSTALLATION
WARNING: Unexpected Start-up Hazard
Disconnect and lock out power before
servicing. Failure to follow these instructions could
result in serious personal injury or death and
property damage.
NOTE: Do not spread the inner and outer
guards more than necessary for guard
removal or installation. Over spreading the
guards may alter their fit and appearance.
Removal
a. Remove the two capscrews that hold the
outer (motor side) coupler guard to the
support bracket(s).
b. Spread the outer guard and pull it off the
inner guard.
c. Remove the capscrew that holds the inner
guard to the support bracket.
d. Spread the inner guard and pull it over the
coupler.
Installation
a. Check coupler alignment before
proceeding. Correct if necessary.
b. Spread the inner guard and place it over
the coupler.
c. With the inner guard straddling the
support bracket, install a capscrew
through the hole (or slot) in the support
bracket and guard located closest to the
pump. Do not tighten the capscrew.
d. Spread the outer guard and place it over
the inner guard.
