DESCRIPTION
The 8200 Series Centrifugal Fire Pumps are
framed mounted pumps which feature – high
efficiency, rugged construction, compact
design, foot mounted volute and regreasable
bearings. These features, along with the
horizontal split case, make installation,
operation and service easy to perform.
OPERATIONAL LIMITS
Unless special provisions have been made
for your pump by ITT A-C Fire Pump
Systems, the operational limits for 8200
Series Centrifugal Fire Pumps are as follows:
MAXIMUM WORKING PRESSURE
Listed on pump nameplate.
SEAL OPERATING LIMITS
PACKING
PH Limitations 7-9; Temperature Range 0 to
+200°F
PUMP IDENTIFICATION
There are two identification plates on each
pump. The pump rating plate gives
identification and rating information. Figure 1
shows an example of a typical Rating Plate.
Permanent records for this pump are
referenced by the Serial Number and it must,
therefore, be used with all correspondence to
order all spare parts and replacement parts.
The fourth digit indicates the specific pump
on orders for more than one pump. For
example, if an order called for six pumps, all
pumps would have the same first three sets
of digits and the last digit will change to
identify each of the six. (e.g. 03-123456-0101
, 03-123456-01-02, etc.)
The frame plate, shown below in Figure 2,
gives information concerning the bearings
and their lubrication. The inboard and
outboard bearing numbers refer to the
bearing manufacturer’s numbers.
For use on open or closed systems which
require a large amount of makeup water, as
well as systems which are subjected to widely
varying chemical conditions and solids
buildup.

INSTALLATION
PUMP LOCATION
Locate the pump so there is sufficient room
for inspection, maintenance and service. If
the use of a hoist or tackle is needed, allow
ample head room.
WARNING: Falling Objects Hazard
Eyebolts or lifting lugs, if provided, are for
lifting only the components to which they are
attached. Failure to follow these instructions could
result in serious personal injury or death, or
property damage.
If lifting base pump is required, use a nylon
string, chain, or wire rope, hitch around both
bearing supports. If lifting of the entire pump is
required, do so with slings placed under the
base rails as shown.
Care must be taken to size equipment for
unbalanced loads which may exist if the
motor is not mounted on the base at the time
of lifting. Motor may or may not be mounted
at the factory.
Pump, base, and driver assemblies where the
base length exceeds 100 inches may not be
safe to lift as a complete assembly. Damage to
the baseplate may occur. If the driver has
been mounted on the baseplate at the factory,
it is safe to lift the entire assembly. If the driver
has not been mounted at the factory, and the
overall baseplate length exceeds 100 inches,
do not lift the entire assembly consisting of
pump, base, and driver. Instead, lift the pump
and baseplate to its final location without the
driver. Then mount the driver.
The best pump location for sound and
vibration ab-sorption is on a concrete floor
with subsoil underneath. If the pump location
is overhead, special precautions should be
undertaken to reduce possible sound
transmission. Consult a sound specialist.

If the pump is not on a closed system, it
should be placed as near as possible to the
source of the liquid supply, and located to
permit installation with the fewest number of
bends or elbows in the suction pipe.
The installation must be evaluated to
determine that the Net Positive Suction Head
Available (NPSHA) meets or exceeds the Net
Positive Suction Head Required (NPSHR), as
stated by the pump performance curve. See
page 11 for more details on proper suction
piping installation.
RECEIVING PUMP
Check pump for shortages and damage
immediately upon arrival. (An absolute must.)
Prompt reporting to the carrier’s agent with
notations made on the freight bill, will
expedite satisfactory adjustment by the
carrier.
Pumps and drivers normally are shipped from
the factory mounted and painted with primer
and one finish coat. Couplings may be either
completely assembled or have the coupling
hubs mounted on the shafts and the
connecting members removed. When the
connecting members are removed, they will
be packaged in a separate container and
shipped with the pump or attached to the
base plate.
NYLON SLING,
CHAIN OR WIRE
ROPE
Shafts are in alignment when the unit is
shipped; however, due to shipping, the
pumps may arrive mis-aligned and, therefore,
alignment must be established during
6
installation. ITT AC Fire Pump Systems has
determined that proper and correct alignment
can only be made by accepted erection
practices. Refer to the following paragraphs
on “Foundation,” “Base Plate Setting,”
“Grouting Procedure,” “Alignment Procedure”
and “Doweling.”
collect should be blown out with compressed
air.
Make sure there is a suitable power source
available for the pump driver. If motor driven,
electrical characteristics should be identical to
those shown on motor data plate.
TEMPORARY STORAGE
If the pump is not to be installed and operated
soon after arrival, store it in a clean, dry place
having slow, moderate changes in ambient
temperature. Rotate the shaft periodically to
coat the bearings with lubricant and to retard
oxidation, corrosion, and to reduce the
possibility of false brinelling of the bearings.
LOCATION
The pump should be installed as near the
suction supply as possible, but no less than
five suction diameters (refer to page 11,
suction and discharge piping section) with the
shortest and most direct suction pipe
practical. The total dynamic suction lift (static
lift plus friction losses in suction line) should
not exceed the limits for which the pump was
sold.
The pump must be primed before starting.
Whenever possible, the pump should be
located below the fluid level to facilitate
priming and assure a steady flow of liquid.
This condition provides a positive suction
head on the pump. It is also possible to prime
the pump by pressurizing the suction vessel.
When installing the pump, consider its
location in relation to the system to assure
that sufficient Net Positive Suction Head
(NPSH) at pump suction is provided.
Available NPSH must always equal or exceed
the required NPSH of the pump.
FOUNDATION
A substantial foundation and footing should
be built to suit local conditions. The
foundation must be substantial enough to
absorb vibration. (Hydraulic Institute
Standards recommends the foundation weigh
at least five (5) times the weight of the pump
unit.) It must form a permanent and rigid
support for the baseplate. This is important in
maintaining the alignment of the flexibly
coupled unit.
The foundation should be poured without
interruption to within 1/2 to 1-1/2 inches of the
finished height. The top surface of the
foundation should be well scored and
grooved before the concrete sets; this
provides a bonding surface for the grout.
Foundation bolts should be set in concrete as
shown in Figure 5. An optional 4-inch long
tube around the bolts at the top of the
concrete will allow some flexibility in bolt
alignment to match the holes in the base
plate. Allow enough bolt length for grout,
shims, lower base plate flange, nuts and
washers. The foundation should be allowed
to cure for several days before the base plate
is shimmed and grouted.

PIPE SLEEVE
BOLT
The pump should be installed with sufficient
accessibility for inspection and maintenance.
A clear space with ample head room should
be allowed for the use of an overhead crane
or hoist sufficiently strong to lift the unit.
NOTE: Allow sufficient space to be able to
dismantle pump without disturbing the pump
inlet and discharge piping.
Select a dry place above the floor level
wherever possible. Take care to prevent
pump from freezing during cold weather when
not in operation. Should the possibility of
freezing exist during a shut-down period, the
pump should be completely drained, and all
passages and pockets where liquid might

remove coupling guard for checking
alignment.)
d. If alignment needs improvement, add
shims or wedges at appropriate positions
under base, so that retightening of anchor
nuts will shift shafts into closer alignment.
Repeat this procedure until a reasonable
alignment is reached.

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 6).
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.
SEE ANSI/OSHA COUPLER GUARD
REMOVAL/INSTALLATION
(SEE BELOW)
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,
8
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.
e. Install the outer guard capscrews by
following the step stated below which
pertains to your particular pump:
i. For pumps with a motor saddle support
bracket: Ensure the outer guard is
straddling the support arm, and install
but do not tighten the two remaining
capscrews.
ii. For pumps without a motor saddle
support bracket: Insert the spacer
washer between the holes located
closest to the motor in the outer guard,
and install, but do not tighten, the two
remaining capscrews.
f. Position the outer guard so it is centered
around the shaft, and so there is less than
a 1/4" of the motor shaft exposed. On
guards that utilize a slotted support
bracket, the inner guard will have to be
positioned so there is only a 1/4" of the
pump shaft exposed.
g. Holding the guard in this position, tighten
the three capscrews.

Proceed with this method only if satisfied that
face and outside diameters of the coupling
halves are square and concentric with the
coupling borers. If this condition does not
exist or elastomeric couplings do not make
this method convenient, use Method 2.
1. Check angular misalignment using a
micrometer or caliper. Measure from the
outside of one flange to the outside of the
opposite flange at four points 90° apart.
DO NOT ROTATE COUPLER.
Misalignment up to 1/64" per inch of
coupler radius is permissible.
2. At four points 90° apart (DO NOT
ROTATE COUPLER), measure the
parallel coupler misalignment by laying a
straight edge across one coupler half and
measuring the gap between the straight
edge and opposite coupler half. Up to a
1/64" gap is permissible.

Final Alignment
Final alignment cannot be accomplished until
the pump has been operated initially for a
sufficient length of time to attain operating
temperature. When normal operating
temperature has been attained, secure the
pump to re-check alignment and compensate
for temperature accordingly. See Alignment
Section.
WARNING: Rotating Components
Hazard
Do not operate pump without all guards in place.
Failure to follow these instructions could result in
serious personal injury or death and property
damage.
OPTIONAL Alignment Procedure
If desired, the pump and motor feet can be
doweled to the base after final alignment is
complete. This should not be done until the
unit has been run for a sufficient length of
time and alignment is within the tolerance.
See Doweling Section.
CAUTION: Extreme Temperature and/or
Flying Debris Hazard
Eye protection and gloves required. Failure to
follow these instructions could result in property
damage and/or moderate personal injury.
NOTE: Pump may have been doweled to
base at factory.
DOWELING
Dowel the pump and driving unit as follows:
a. Drill holes through diagonally opposite feet
and into the base. Holes must be of a
diameter 1/64 inch less than the diameter
of the dowel pins. Clean out the chips.
b. Ream the holes in feet and base to the
proper diameter for the pins (light push fit).
Clean out the chips.
c. Insert pins to be approximately flush with
feet.
