6.4 Design detail
6.4.1 Casing
The pump casing is made from Cast Iron or Ductile Iron,
and is an axially-split double suction volute design with the
suction and discharge flanges and mounting feet cast
integrally with the lower casing half.
Tapped and plugged holes are provided for priming, vent,
drain, and gauge connections. The upper casing half can
be removed without disturbing the suction or discharge
piping. Pump flanges are made with ANSI Class 125 or
250 drillings, and come in the following combinations,
[Suction/Discharge]: 125/125; 125/250; and 250/250.
The suction and discharge are on a common centerline in
the vertical direction for all pump model types; and on a
common horizontal centerline for model types 8100, 8150,
and 9100.
6.4.2 Impeller
The impeller is an enclosed double suction type made of
bronze, which is statically and hydraulically balanced. The
impeller is firmly secured to the shaft by a key positioned
by shaft sleeves and both locked in place by shaft sleeve
lock nuts.
The shaft sleeves are made of bronze and protect the
shaft from wear and from contact with the pumped liquid.
Shaft sleeves are locked in place by threaded bronze
shaft sleeve nuts. An O-ring is furnished under the sleeve
to prevent leakage.
6.4.5 Stuffing Box
The stuffing box consists of die formed, graphite coated,
synthetic fiber packing rings; and a split type gland to
permit removal and access to the packing. The 8100
stuffing box housing is made of cast iron, and is separate
from the pump casing. The stuffing box housing is drilled
and tapped for drain connections.
6.4.6 Casing Rings
The casing rings are made of bronze and are installed
with an anti-rotation device and designed to restrict
leakage across the ring fit.
6.4.7 Bearings
The bearings are grease lubricated rolling type selected to
carry radial and thrust loads. The outboard bearing is
retained to handle the axial thrust.
6.4.8 Bearing Housings
The bearing housings are bolted to the pump and are
piloted to positive alignment of the rotating element. The
housings provide a fit for the inboard bearing that allows
freedom for thermal expansion while the outboard
bearing(s) are clamped in place in order to take all the
thrust loads and keep the rotating element in its proper
axial location. Openings for adding grease and draining
grease are provided.
6.4.9 Baseplate
The baseplate is welded construction, manufactured from
steel and is sufficiently rigid to support the pump and the
driver.
6.4.10 Coupling
The coupling is of the flexible type. The coupling hubs are
secured to the driver and the driven shafts by a setscrew
located over the key.
6.4.11 Coupling Guard
The coupling guard is made of metal, and meets the
requirements of EN ISO 13857.
6.4.12 Rotation
Pumps have a clockwise or counterclockwise rotation
when viewed from its driven end.
6.4.3 Shaft
The shaft is made of AISI 1045 or 4140 steel and of ample
size to operate under load with a minimum deflection.

6.7 Dimensions and weights
Refer to the general dimensional drawing supplied with
the pump unit
7 Installation
This section describes the installation of a complete
pump unit.
CAUTION
7.1 Location
Install the pump in a well-ventilated, dry place above the floor
level wherever possible. Take care to prevent the pump from
freezing during cold weather when not in operation.
The pump should be installed with sufficient space around it
to facilitate ventilation and accessibility for inspection,
maintenance and service. A clear space with ample head
room should be allowed for the use of an overhead crane or
hoist to lift the unit.
Install the pump as near to the suction supply as possible,
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.
When installing the pump, consider its location in relation to
the system to assure that sufficient Net Positive Suction Head
[NPSH] is available at the pump inlet connection. Available
NPSH [NPSH
NPSH [NPSH
The pump must be primed before starting. Whenever
possible, the pump should be located below the fluid level to
assure priming. This condition provides a positive suction
head on the pump. It is also possible to prime the pump by
pressurizing the suction vessel.
Installations should be performed by persons
qualified in the setting up of pumping
equipment.
WARNING
All electrical work should be carried out by
qualified personnel.
WARNING
Engine-driven pump units:
The engine must be provided with adequate
ventilation to satisfy the requirements of the
combustion system, and allow adequate
dissipation of radiated heat and exhaust
emissions.
] must always equal or exceed the required

] of the pump.
R

7.2 Foundation
We recommend that the pump unit should be installed on a
concrete foundation, sufficiently substantial to absorb
vibration and to form a permanent, rigid support for the
baseplate.
A base of concrete weighing 3 to 5 times the weight of the
pump unit is recommended.
The foundation should be 3 to 6 inches [75 to 150mm] longer
and wider than that of the baseplate that will be installed.
Foundation bolts must match those of the base plate. The
foundation should be poured without interruption to within 1/2
to 1-1/2 inches [12.7 to 38.1mm] of the finished height. The
top surface of the foundation should be well scored and

Exhaust pipes shall be installed with clearances of at least 9
inch [229mm] to combustible materials.
7.6.8 Pressure Gages
Properly sized pressure gages should be installed in both the
suction and discharge nozzles in the gauge taps provided.
The gauges will enable the operator to easily observe the
operation of the pump, and also determine if the pump is
operating in conformance with the performance curve.
7.7 Final alignment
WARNING
Do not operate pump with coupling out of
alignment. Ensure final coupling alignment is
within the values according to the coupling
manufacturer’s instructions. Coupling, pump,
or driver failure may occur. Failure to follow
these instructions could result in serious
personal injury.
After connecting piping to the pump, rotate the shaft several
times by hand to ensure that there is no binding and all parts
are free. Recheck the coupling alignment, as previously
described, to ensure that there is no pipe strain. Correct, if
necessary, by adjusting the motor only.
7.6.9 Stuffing box lubrication
7.6.9.1 General guidelines
Contaminants in the pumped liquid must not enter the
stuffing box. These contaminants may cause severe
abrasion or corrosion of the shaft, or shaft sleeve, and rapid
packing deterioration; even plugging the stuffing box flushing
and lubrication system.
The stuffing box must be supplied at all times with a source
of clean, clear liquid to flush and lubricate the packing.
This is normally achieved with a supply from the pump
discharge volute to the stuffing box. A control valve may be
fitted into the supply line to control the pressure to the
stuffing box.
7.6.9.2 Packing
Pumps are normally packed before shipment. If the pump is
installed within 60 days after shipment, the packing will be in
good condition with a sufficient supply of lubrication.
If the pump is stored for a longer period, it may be necessary
to repack the stuffing box. In all cases, however, inspect the
packing before the pump is started.
It is important to establish the optimum flushing pressure that
will keep contaminants from the stuffing box cavity. If this
pressure is too low, fluid being pumped may enter the stuffing
box. If the pressure is too high, excessive packing wear may
result; and extreme heat may develop in the shaft causing
higher bearing temperatures.
The most desirable condition, therefore, is to apply seal water
at a flow rate of approximately 0.25 gpm [0.95 lpm] at a
pressure approximately 15-20 psig [1 bar] above the
maximum stuffing box pressure. [Approximately one [1] drop
per second.]
NOTE: Packing adjustment is covered in section 9,
Maintenance.
7.8 Electrical Connection
WARNING
Risk of electric shock. All electrical
connections shall be performed by a qualified
The operating voltage and frequency are marked on the
motor nameplate.
The motor must be suitable for the power supply at the
installation site.

electrician in accordance with all applicable
codes, ordinances and good practices.
Failure to follow these instructions could
result in serious injury, death and/or property
damage.
WARNING
Risk of injury due to rotating parts. Isolate the
motor from its supply voltage and keep it locked
out when performing any work on the pump.
NOTICE
Follow the instructions of the motor
manufacturer.
NOTICE
Engine-driven pump units: The requirement for
the electrical connection of the engine unit is
covered in the engine manufacturer’s
Installation Manual.

8 Start-up, operation and
shutdown
8.1 Start-up
WARNING
Start-up should be carried out by authorized
personnel. Do not start the pump until all prestart-up checks have been performed
11. Assure that coupling is properly lubricated, if required.
12. Assure that pump is full of liquid and all valves are
properly set and operational, with the discharge valve
closed and the suction valve open. Purge all air from top
of casing.
13. Check rotation. Be sure that the driver operates in the
direction indicated by the arrow on the pump casing as
serious damage can result if pump is operated with
incorrect rotation.
8.1.2 Priming
CAUTION
Do not start the pump until it has been
completely filled with liquid and vented. The
pump must not run dry as this will result in
serious damage to the pump.
WARNING
Electric Shock Hazard: Electrical connections
are to be made by qualified personnel, in
accordance with applicable codes,
ordinances, and good practices.
NOTICE
See also installation and operating
instructions for the electric motor, if
applicable.
NOTICE
See also installation and operating
instructions for the diesel engine, if
applicable. We recommend that you register
the diesel engine with the manufacturer
before start-up. Otherwise, the engine
manufacturer cannot provide any warranty if
the engine is faulty.
8.1.1 Preparation for startup
WARNING
Unexpected Start-up Hazard: Disconnect and
Before the initial start of the pump, perform the following
inspections:
1. Remove all corrosion protection materials, referenced
in section 5.3 Storage, in accordance with the
manufacturer’s recommendations.
2. Check alignment between pump and driver, (motor or
engine). See section 7.5 Initial Alignment.
3. Check that all pipes and hoses are installed correctly.
4. Check all electrical connections. Check voltage, phase,
and frequency.
5. Check suction and discharge piping and pressure
gauges for proper operation.
6. Check that all safety devices are installed.
7. Turn rotating element by hand to assure that it rotates
freely.
8. Check stuffing box adjustment, lubrication, and piping.
9. Check driver lubrication.
10. Assure that pump bearings are properly lubricated.
lockout power before performing pre-start-up
checks. Failure to follow these instructions
could result in serious personal injury or
death.
NOTICE
Flushing: New and old systems should be
flushed to eliminate all foreign matter. Heavy
scale, welding splatter and wire or other large
foreign matter can clog the pump impeller.
If the pump is installed with a positive head on the suction, it
can be primed by opening the suction valve, and loosening
the vent plug on top of the casing (Do not remove), allowing
air to be purged from the casing.
If the pump is installed with a suction lift, priming must be
done by other methods such as foot valves, ejectors, or by
manually filling the casing and suction line.
All drains should be closed when filling the system. Filling
should be done slowly so that excessive velocities do not
cause rotation of the pumping elements which may cause
damage to the pump or its driver. The adequacy of the piping
anchors and hangers may be checked at this time by
mounting a dial indicator off of any rigid structure not tied to
the piping and setting the indicator button on the pump flange
in the axial direction of the nozzle.
If the indicator moves, as the filling proceeds, the anchors
and supports are not adequate or set properly and should be
corrected.
8.2 Coupling Guard
WARNING
Unexpected Start-up Hazard: Disconnect and
lockout power before performing pre-start-up
checks. Failure to follow these instructions
could result in serious personal injury or
death.
NOTICE
The coupling guarding described herein
refers to guarding that is supplied by A-C Fire
Pump for pumps that have a motor driver. For
pumps with an engine driver refer to the
engine manufacturers instructions, supplied
with the pump unit.
NOTE: The coupling guard fasteners have devices that keep
them from completely detaching from the guard or the pump.
Do not remove these devices or separate the fasteners from
the guard or the pump.
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.

8.3 Operation
8.4 Shutdown
WARNING
Pump units have a sound pressure level
higher than 85 dB(A). Hearing protection
must be worn when the pump is running.
WARNING
Do not operate the pump at or near zero flow,
i.e. closed discharge valve. Explosion could
result. Failure to follow these instructions
could result in serious personal injury and
part damage.
WARNING
Do not operate the pump unless all guarding
are in place.
8.3.1 General Procedure
1. Close drain valves and valve in discharge line.
2. Open fully all valves in the suction line.
3. Slowly turn on seal water to the stuffing box. (If pumped
fluid is dirty or if leakage of air is to be prevented, these
lines should be always left open.)
4. Prime the pump. [NOTE: If the pump does not prime
properly, or loses prime during start-up, it should be shut
down and the condition corrected before the procedure
is repeated.]
5. Start the pump driver (Engines may require warming up;
consult the manufacturer’s instructions).
6. When the pump is operating at full speed, open the
discharge valve slowly. This should be done promptly
after start-up to prevent damage to pump by operating
at zero flow.
7. Adjust the liquid seal valves to produce the
recommended pressure for the packed stuff box.
8.3.2 Optional Checklist
NOTICE
This section applies to parameters that
contribute to assessing the performance of
the pump unit.
WARNING
Escaping pressurized liquids. Liquid draining
from the pump could result in personal injury
and equipment damage.
NOTICE
This section applies to the complete pump
unit. See also installation and operating
instructions for the driver, (electric motor or
diesel engine), and controller.
The following steps will take care of most normal shutdowns
of the pump, i.e. maintenance or to make any further
adjustments of process piping, valves, etc., as required.
1. Shut off power supply to the driver.
2. Close suction and discharge valves.
3. Close seal liquid valves. (If pumped liquid is dirty, or if
leakage is to be prevented, these lines should always
be left open, except when the pump is completely
drained.)
4. Open drain valves as required.
8.5 Returning to service
After long-term storage and before commissioning, check
seals, bearings, and lubrication.
8.6 Freeze Protection
CAUTION
If heat is used to keep the pump from
freezing, do not let the temperature rise
above 150°F [66°C].
Pumps that are shut down during freezing conditions should
be protected by one of the following methods:
1. Drain the pump; remove all liquid from the casing.
2. Keep fluid moving in the pump and insulate or heat the
pump to prevent freezing.
1. Driver/Pump Rotation: Check the rotation each time that
the motor leads have been disconnected. Be sure that
the driver operated in the direction indicated by the
arrow on the pump casing.
2. Flow: An accurate measurement of the flow rate is
difficult to in the field. Venturi meters, flow nozzles,
orifice plates, or timing the draw down in a wet well are
all possible methods. Record any reading for future
reference.
3. Pressure: Check and record both suction and discharge
pressure gauge readings for future reference.
4. Power: Record voltage, amperage per phase, kilowatts if
an indicating wattmeter is available, and the pump
speed.
5. Temperature: Check and record the bearing temperature
using a thermometer. Temperature should not exceed
225°F [107°C] for polyurea-greased bearings and180°F
[82°C] for lithium-greased bearings.

8.7 Field testing
A performance curve for the pump-unit is included in the
document package shipped with the pump unit or it can be
obtained from A-C Fire Pump. This can be used in
conjunction with a field test, if one is required.
All A-C Fire Pump tests and curves are based on the
Hydraulic Institute Standards. Any field tests must be
conducted according to these standards.
Unless otherwise specifically agreed, all capacity, head, and
efficiencies are based on factory tests using clear water at a
temperature not greater than 85°F [29°C].

Check the shaft to ensure that it can be rotated after fitting
each packing ring.
Fit as many rings as possible into the stuffing box without
having any packing protruding, and without over-compressing
the packing
NOTE: The last ring in each box may not be required until
after the pump has operated for a period of time.
NOTE: When supplied, the seal cage will replace the third
packing ring from the bottom of the stuffing box. The seal
cage must be aligned with the seal water inlet when the
packing is compressed.
Bring the gland follower up squarely against the last packing
ring and tighten the nuts evenly to finger pressure.
9.4.5 Packing Adjustment
Install the proper flush set up.
Start the pump and allow the packing to leak freely at startup. During the break-in period, adjustments should be made
gradually (tightening the gland nuts one 1/4 revolution at a
time), allowing 5 to 10 minutes between adjustments.
After the break-in period, the leakage rate can be controlled
to 40 to 60 drops per minute.

7. Remove all casing main joint cap screws [2-904-1] and
dowels [2-916-1].
8. Using the slot in the casing main joint, separate the
casing halves with a pry bar. Lift the upper half casing
[2-001-0] by the cast lugs.
NOTE: Some casings have jacking screws.
9. Series 8100 only: Tap the stuffing boxes [3-073-9] with
a soft-headed hammer to break the seal between the
stuffing box and the lower casing [2-001-0].
10. Series 8200 and 9100: Remove packing [1-924-9] and
seal cage [1-013-9] from each stuffing box.
11. Series 8150, 8200, and 9100: Remove cap screws [3-
904-9] which hold the bearing housings [3-025-3] to the
lower casing.
12. The rotating element may now be removed. Carefully lift
the complete rotating element, protecting the packing
surface on the outside diameter of the shaft sleeve [3009-9] from damage and place on two support blocks.
10.2.2 Bearing Housing
1. Remove four cap screws [3-904-9] from each bearing
housing [3-025-3, 3-025-4] and remove the bearing
housings from the shaft [3-007-0].
2. Bend back the lock-washer tab and remove locknut [3516-4] and lock-washer [3-517-4] from the outboard
end of the shaft and, using a bearing puller, remove the
bearing [3-026-4] from the shaft. Remove the inboard
end bearing [3-026-3] in the same manner.
NOTE: Locknut and lock-washer are not used on inboard
end bearings.
3. Series 8200 and 9100: Remove bearing covers [5-018-
0] out of bearing housings. Pull deflectors [3-136-9] off
the shaft. Slide stuffing box bushings [6-008-0] off the
shaft.

Replace if grooved, pitted or worn.
10.3.3 Gaskets and O-rings
After dismantling, discard and replace.
10.3.4 Bearings
It is recommended that bearings are not reused after
removal from the shaft.
10.3.5 Bearing isolators and lip seals
1. The lubricant, bearings and bearing housing seals are
to be inspected for contamination and damage.
Damaged parts should be replaced.
2. If bearing damage is not due to normal wear and the
lubricant contains adverse contaminants, the cause
should be corrected before the pump is returned to
service.
3. Bearing isolators (if used) should be inspected for
damage but are normally non-wearing parts and can be
usually reused.
Used parts must be inspected before
assembly to ensure that the pump will
operate correctly.
CAUTION
Do not reuse the ball bearings.

outboard side only.
7. Install both bearing housings.
10.4.4 Rotating element
After completion of the preceding steps, carefully place the
shaft assembly into the lower half pump casing.
10.4.4.1 Series 8100
1. Set the rotating element in the pump casing [2-001-0],
assuring correct rotation. Locate both stuffing box
tongues in their respective casing grooves.
2. Locate pins [3-943-9] in the stuffing box and the casing
wear rings in their respective slots at the casing parting
line. Correct any O-ring bulging.
10.4.4.2 Series 8200
1. Set the rotating element in the pump casing [2-001-8],
assuring correct rotation. Correctly locate casing ring
pins, stuffing box bushing pins, and interstage
diaphragm pins in the casing main joint slots. (Sliding
the inboard bearing housing towards the coupling
slightly will ease assembly).
2. Bolt the outboard bearing housing in place. Ensure that
both housings are seated properly in the lower half
casing.
