unless required. You may request them from your Peerless
representative.
2. Receiving the product
2.1 Unpacking the product
Do not unpack more than required to verify that the equipment is
complete and undamaged unless installed immediately. Look
through all packaging material that is to be discarded to ensure no
parts or instructions are discarded accidentally. In some shipments,
small boxes containing additional parts are bound to pump skids.
Leave small parts in their shipping container until installation. While
unpacking, make sure that pump unit accessories are clearly
marked indicating the exact pump unit they should be used with.
The product must be inspected after transport and before
installation.
To complete the inspection, follow the steps below:
1.
Check the product for transport damage. Contact the
transporter immediately in case of damage.
2.

English (US)
2.2 Inspecting the product
If a seismic analysis is required, please refer to the
governing bodies recommended for grouting and
foundation requirements.
The customer must supply complete specifications for earthquakeresistance requirements including seismic criteria, acceleration,
magnitudes, frequency spectrum, location and direction relative
to the pump and qualification procedure.
3.3 Mechanical installation
3.3.1 Recommendation for pump foundation
All rotating equipment generates vibrations when turning at high
speeds. Proper installation and anchorage of the pumps and
installation accessories are critical to limit vibrations and achieve
reliable installation. To ensure acceptable vibration levels in the
field, all parts of the system must be sufficiently stiff and firmly
anchored to minimize vibrations:
WARNING
Crushing hazard
Death or serious personal injury
‐ Make sure all persons stand clear of the load and the
lifting equipment while product is lifted, lowered,
loaded and unloaded. Do not allow anyone to stand
on, under, or near the load.
Do not subject the pump to excessive g-forces during
handling or transport.
2.4 Scope of delivery
This applies for pumps above 13 hp (10 kW).
•
The foundation and concrete should be of adequate strength to
support the weight of the pump including accessories, the
weight of the liquid passing through the pump, and the forces
generated by the pump.
•
The mass of the concrete foundation should be a minimum of
three to five times the mass of the supported equipment and
should have sufficient rigidity to withstand the axial, transverse,
and torsional loadings generated by these machines.
•
The foundation should be 5.9 in (15 cm) wider than the base
plate for pumps up to 469 hp (350 kW) and 9.8 in (25 cm) wider
for larger pumps.
•
The concrete used in the foundation should have a minimum
tensile strength of 362 lbf/in2 (250 N/cm2).
•
Always use a non-shrink epoxy grout to fasten the pump base
plate to the foundation.
A typical shipment will include:
•
one skid with the fire pump and the driver mounted on the base
plate
•
one skid with the controller and accessories, if any
•
installation and operating instructions.
Refer to the original order in case of questions about shipping, for
example, special arrangements with third-party vendors for shipping
and storage.
3.3.2 Pump foundation
Large pumps will be mounted on a steel base anchored to
two concrete pillars.
3. Installing the product
3.1 Factory support
For Engineered to Order (ETO) products, Peerless recommends
that you invite a Peerless service engineer to supervise the
installation and startup. This is to ensure a proper installation.
Peerless recommends that you review the instructions
provided with the pump.
3.2 Location
Install the pump permanently on a firm, raised concrete foundation
of sufficient size to dampen any vibration and prevent any deflection
or shaft misalignment. The foundation may float on springs or be a
raised part of the floor.
Proceed like this:
1.
Pour the foundation without interruption to 0.75- 1.5 in (20-40
mm) below the final pump level. Leave the top of the
foundation rough. Then clean and wet it down.
2.
Scour and groove the top surface of the foundation before the
concrete sets to provide a suitable bonding surface for the
grout.
3.
Place anchor bolts in pipe sleeves for positioning allowance.
4.
Allow enough bolt length for grout, base flange, nuts, and
washers.
5.
Allow the foundation to cure several days before proceeding to
install the pump.
Install the product in a location that meets the following
requirements:
3.2.1 Minimum space
Always allow sufficient accessibility space for maintenance and
inspection. Provide a clearance of 24 inches (610 mm) with ample
head room for use of overhead lifting equipment strong enough to
lift the product.
3.2.2 Seismic analysis
When the pump is located in a seismically active area or in certain
critical installations, ensure that the pumps, supports, and
accessories are earthquake-resistant. The design specifications for
earthquake resistance vary depending on the geographical area
and the class of the equipment. The class of the
equipment depends on defining how critical is the survival of the
equipment, the characteristics of the structure's response to
accelerations, and the foundation supporting the pump.

5.
After pump alignment has been established, put nuts on the
anchor bolts and tighten them just enough to keep the base
plate from moving.
6.
Construct a formwork around the concrete foundation and pour
grout inside the base plate. The grout will compensate for the
uneven foundation, distribute the weight of the pump, and
prevent shifting.

3.3.3 Positioning the pump
When the raised concrete foundation has been poured and allowed
to set, proceed as follows:
WARNING
Overhead load
Death or serious personal injury
‐ Never attempt to lift the entire pump by means of
eyebolts screwed into the driver mounting holes. This
attachment point may not be strong enough to carry
the weight of the entire unit.
Adequate space above the installation site must be
provided to accommodate rigging and the longest section
of the pump to be handled.
1.
Lower the base plate over the anchor bolts and rest it on loose
adjustment wedges or shims placed near each anchor bolt and
at intervals not exceeding 24 in (610 mm) along each side.
2.
Place the shims or wedges so that they raise the bottom of the
base plate 0.75-1.25 in (19-32 mm) above the foundation,
allowing clearance for grout.
3.
Level the pump shaft, flanges, and base plate using a level,
adjusting the wedges or shims, as required.
If the pump is equipped with jacking screws, use
them to lift the pump and adjust the wedges or shims.
8
Allow for the grout to cure fully before proceeding with torquing
the anchor bolts and the pipe connections.
8.
After the grout has thoroughly hardened, check the anchor
bolts and tighten them if necessary. Recheck the pump
alignment after tightening the anchor bolts.

3.3.4 Dowel pins
To comply with the Hydraulic Institute recommendations, all pumps
should be dowelled.
The pump feet can be drilled for dowels at the factory or in the field.
Doweling the pump feet accomplishes the following:
•
Prevents lateral movement.
•
Eases realignment if the pump is removed from the base.
•
Temporarily holds the pump if the hold-down bolts loosen.
3.3.5 Installing dowel pins
If dowel holes were not drilled in the pump feet at the factory then
determine the dowel and hole size by measuring the diameter of the
mounting hole in the pump foot and subtract 3/8".
Peerless recommends the use of straight dowel pins as described
in the following steps:
1.
Check the coupling alignment and correct if necessary.
2.
Drill holes in opposite pump feet. The holes should be 1/64"
smaller than the dowel diameter.
3.
Clear the debris.
4.
Ream the holes in the pump feet and base to the correct
diameter. Allowing for a push fit.
5.
Clear the debris.
6.
Insert the dowels to a depth that leaves sufficient thread to
attach a nut.
7.
Thread the nuts onto the dowel and tighten.
Pressure gauges will enable the operator to monitor the
pump performance and determine whether the pump
conforms to the parameters of the performance curve
3.4.1 Engine preparation
The following installation requirements help to ensure safe and
efficient operation of a pumping unit driven by a diesel engine:
1.
Ensure that the operator is familiar with the installation and
service manual supplied with the engine.
2.
Ventilate the area around the engine to keep the ambient
temperature as low as possible. With 60 °F (15.6 °C) as a data
point, every Δ 10 °F (Δ 6 °C) rise in temperature reduces the
horsepower of the engine by approximately 1%.
3.
Provide adequate air for efficient combustion.
4.
Provide the engine with an efficient exhaust system so that the
combustion gasses discharge with a minimum of back
pressure.
5.
Ensure that the fuel system is of adequate capacity and meets
codes and regulations.
6.
Provide ample space to access the engine for maintenance.
7.
Provide correct rotation of the pump. Engine rotation is
determined at the factory, and no change to engine rotation can
be made in the field.
If cavitation, vapor binding, or other unstable operating
situations occur, the pressure gauges will indicate with
wide fluctuation in the inlet and outlet pressures.
3.5.1.2 Vibration dampers
To prevent the transmission of vibrations to foundations and
surrounding structures, isolate the pump and foundation from
connected structures by means of vibration dampers. The selection
of the correct vibration damper requires the following data:
•
forces transmitted through the damper
•
motor speed(s)
•
required dampening in %.
The selection of a vibration damper differs from installation to
installation. In certain cases, a wrong damper may increase the
vibration level. Peerless recommends that the vibration dampers be
sized by the supplier. If you install the pump on a foundation with
vibration dampers, always fit expansion joints on the pump flanges.
Install expansion joints on the pump flanges to prevent the
pump from "hanging" in the flanges.
3.5 Mechanical installation
3.5.1 Pipes and connections
3.5.1.1 Inlet pipe
The inlet pipe must be installed in a manner that minimizes
pressure loss and permits sufficient liquid flow into the pump during
starting and operation.
English (US)
3.4 Installation preparation
3.5.1.3 Inlet pipe
The inlet pipe must be installed in a manner that minimizes

Observe the following precautions when installing the inlet pipe:
Observe the following precautions when installing the inlet pipe:
•
•
Run the inlet pipe as direct as possible, and ideally, make sure
the length is at least ten times the pipe diameter. A short inlet
pipe can be the same diameter as the inlet port. A long inlet
pipe must be one or two sizes larger than the inlet port,
depending on the length, and with a reducer between the pipe
and the inlet port.

•
•
Install a gate valve in the inlet line to be able to isolate the
pump during shutdown and maintenance, and to facilitate
pump removal. Where two or more pumps are connected to the
same inlet pipe, install two gate valves to be able to isolate
each pump from the pipe.

3.5.1.4 Outlet pipe
•
A short outlet pipe can be the same diameter as the pump
outlet port. A long outlet pipe must be one or two sizes larger
than the outlet port, depending on the length.
•
It is best to use long horizontal outlet pipes.
•
Install a non-return valve to protect the pump from backflow
and excessive backpressure. The check valve should be
installed between the isolation valve and pump.
Pump backspin and hydraulic shock can cause severe
damage to the pump and driver.
•
Install a gate valve near the outlet port to be able to isolate the
pump during shutdown and maintenance, and to facilitate
pump removal.
•
Any high points in the outlet pipe may entrap air or gas and
thus reduce pump operation.
•
excessive force on the pipes distorting or shifting the machine.
•
settling of the building.
•
shifting of pump or driver on the base plate or foundation.
Misalignment may be the cause of:
•
noisy pump operation
•
vibration
•
premature bearing failure
•
excessive coupling wear.
3.5.3.1 Checking the alignment
The procedure for verifying the alignment of a pump and driver
connected by a flexible coupling, mounted on a common base plate
are:
1.
Disconnect the coupling halves.
2.
Set the coupling gap to the recommended alignment
dimension.
3.
Test for parallel and angular alignment with a straight edge and
feeler gauge.
4.
An alternate test for parallel and angular alignment may
be made as follows with a dial indicator mounted:
• Scribe the index lines on the coupling halves or set the
indicator dial to zero.
• Slowly turn both coupling halves so that the index lines
match.
Operating pumps against a closed valve will cause an
increase in pressure and power.
If an increaser is used on the outlet pipe to increase the
pipe size then it should be placed between the non-return
valve and the pump. If expansion joints are used then
they should be placed between the pipe support or anchor
and the non-return valve.
• Observe the dial reading to determine whether pump or
driver
• Acceptable parallel and angular alignment occur when total
indicator reading (complete turn) does not exceed limits
shown on either a tag or decal on the unit or on the unit
outline drawing.
5.
3.5.1.5 Nozzle load
The pipes should be aligned with the pump nozzles to minimize
pump nozzle loads. Refer to ANSI/HI 9.6.2 for assessment of
applied nozzle loads.
3.5.2 Impeller clearance
When a significant operating temperature differential exists
between the pump and driver (i.e. a steam turbine driver
with a pump handling cold liquid), thermal growth causes the
hotter component to rise. You can compensate for this by
initially setting the hotter unit 0.003 to 0.005 in. (0.076 to 0.127
mm) lower. When both units are at normal operating
temperature, make a final check and correct the alignment if
necessary.
To achieve optimal performance and service life, the impeller
clearance must be centered in the volute. Pumps are shipped from
the factory with the impeller clearance set.
Check for correct electric motor rotation while
coupling halves are disconnected.
3.5.3 Alignment
6.
Correct for excessive parallel and angular misalignment by
slightly shifting the leveling wedges under the base plate. Tap
lightly (in or out) with a hammer. Retest alignment each time
after you shift a wedge.
7.
It may be necessary to change the shims under the pump or
driver or even relocate the pump or driver on the base plate.
Make such changes only after you are sure that shifting the
wedges do not achieve alignment.
8.
If wedges are shifted or shims are shifted, recheck the pipe
alignment and the level of the shafts.
Reliable, trouble-free, and efficient operation requires accurate
alignment of pumps and drivers mounted on a common base plate.
Shipping and installation can alter the factory alignment. Therefore,
check the alignment after:
•
mounting.
•
the grout has hardened.
•
the foundation bolts are tightened or adjusted.
•
the pipes to the product are connected.
•
pump, driver or base plate is moved.
Y
To check alignment, mount a dial indicator to measure shaft
movement before and after tightening the flange bolts.
To facilitate accurate field alignment, we do not dowel the
pumps or drivers on the base plates before shipment.
If the product does not stay in alignment after installation, possible
causes of misalignment are:
•
10
setting, seasoning or springing of the foundation.

3.5.3.4 Aligning the engine drivers
3.7 Control, monitoring, and alarm equipment
Engine-driven units are typically supplied with the pump and drive
on a common base plate. For units that are supplied separately,
contact Peerless.
Check control and alarm systems for correct installation
and function according to the manufacturer's instructions.
If a universal drive is installed, contact the manufacturer
for instructions.
1.
Check the angular alignment between the pump and engine
shafts.
2.
Check the parallel alignment between the pump and engine
shafts.
3.
When coupled, verify that the angle between the pump and
drive shaft is less than three degrees. For assistance,
contact Peerless.
4.
Verify that at least 3/4 of the key is engaged with the coupler
and shaft.
Check all alarm point settings.
3.7.1 Stopping the unit/reverse runaway speed
A sudden power and/or discharge valve failure during pump
operation against a static head will result in a flow reversal, and the
pump will operate as a hydraulic turbine in a direction opposite to
that of a normal pump operation.
If the driver offers little resistance while running backward, the
rotational speed may approach the pump specific speed.
4. Preparing the pump for startup
3.5.4 Lubrication, priming and cooling systems
4.1 Lubricating the pump
If supplied, please refer to additional documents attached to the
pump, or contact Peerless.
Before attempting to start the pump, check the following items:
3.6 Electrical connection
All electrical connections must be carried out by a
qualified electrician in accordance with local regulations.
•
lubrication fitting at packing, if applicable
•
lubrication for pump bearing
•
lubrication of the driver
•
oil-cooling connections for the driver, if applicable
•
coupling, refer to the manufacturer's instructions.
Good practice includes the following:
DANGER
Electric shock
Death or serious personal injury
‐ Switch off the power supply before you start any work
on the product.
‐ Make sure that the power supply cannot be switched
on accidentally.
Locate the electrical conduit and boxes so as to avoid obstruction of
the pump.
Check speed versus torque requirements during the starting phase
of a pump against the speed versus torque curve of the driving
motor.
In order to accelerate the pump up to rated speed, the driver should
be capable of supplying more torque at each speed than required
by the pump. In general, this condition is easily attainable with
standard induction or synchronous motors, except under certain
conditions when a motor with high pull-in torque may be required,
such as high specific speed pumps over 5000 US units (100 metric
units) or reduced voltage startup.
To achieve a smooth start for the pumping equipment, consider
connecting autotransformers to the starting panel or using solidstate starters. These provide a gradual increase in voltage up to
rated voltage ensuring even acceleration.
Control, monitoring and alarm equipment
All control and alarm systems should be checked for
correct installation and functioning in accordance with the
manufacturer's instructions. All alarm point settings should be
checked.
Stopping the unit/reverse runaway speed
A sudden power and/or discharge valve failure during
pump operation against a static head will result in a flow reversal,
and the pump will operate as a hydraulic turbine in a
direction opposite to that of a normal pump operation. If the driver
offers little resistance while running backward, the rotational speed
may approach the pump specific speed. This condition is called
runaway speed and causes mechanical problems. Contact Peerless
for aid in preventing this condition.
12
•
Keep lubricant clean, and use a dust-tight cover on the storage
container.
•
Use the oldest lubricant first.
•
Clean the pump lubricant fittings before re-lubricating with
grease.
•
Use clean dispensing equipment.
•
Remove 0.25 in (6.4 mm) of drain pipe plug on the bottom
outside of the bearing housing cover. Inject clean, new grease
forcing out the old grease through the drain opening.
•
Start and run the pump for a short time to eject any excess
grease. Reinstall 0.25 in (6.4 mm) of pipe plug. Wipe off any
ejected grease.
•
Use the proper amount of lubricant. Too much lubricant results
in churning, unnecessary power consumption, rapid heating to
a high temperature and inadequate lubrication.
Normal bearing temperatures vary with the seasons and
environment and may range from 0 to 250 °F (-18 to 121
°C). A continuous rise from the established, normal
operating temperature indicates trouble and probable
failure of the bearing. Shut down the pump immediately.
Tightly pressed packing will result in burnt packing and
scoring of the shaft or shaft sleeve.
WARNING
Electric shock
Death or serious personal injury
‐ Switch off the power supply before you start any work
on the product.
The stuffing box should slowly leak fluid, 40-60 drops per
minute, during operation. When the leak can no longer be
controlled by adjusting the stuffing box gland, add one
additional ring of packing and ensure the gland is loose.
When the leak can no longer be controlled, all packing
rings must be replaced.
Three-phase motor shaft rotation can be reversed by
switching any two of the three power leads.
Do not attempt to switch any leads in a single-phase
motor to change the direction of rotation. The rotation of
most single-phase motors is determined by internal wiring
and cannot be changed easily.
1.
Disconnect the power supply.
2.
Lockout-Tagout the power supply.
3.
Disconnect the coupling from the motor and pump shaft. Motor
shaft spins without driving or contacting the pump shaft.
4.
Rotate the motor shaft by hand in both directions.
Verify that the motor spins without binding.
5.
6.
Momentarily energize the motor.
Verify that the motor spins in the direction indicated on the
pump volute.
•
The stuffing box is packed at the factory.
•
Each ring is cut to the proper length.
The end of the rings must come together and not overlap.
•
The rings are placed in the stuffing box so that the joints of the
packing rings are staggered.
•
The stuffing box is furnished with a lantern or seal ring.
•
The box has a tapped connection for grease lubrication, if
applicable.
- 3 oz. (89 mL) of grease must be injected into the stuffing box
every 24 hours of operation.
Automatic grease seal lubrication systems can be
installed as an accessory.
Install the coupling and guards.
4.3 Guards
WARNING
Moving machine parts or blades
Death or serious personal injury
‐ Guards must not be removed while the pump is
operational. Ensure an approved coupling guard is in
place before operating the pump.
Refer to the accessory manufacturer's safety instructions.
4.4 Flushing the system
Before the pump is installed, we recommend that you clean the
system to remove debris, for example, stubs of welding rod, welding
slag, and loose scale. Protect the pump and other sensitive parts
with startup strainers.
4.5 System decontamination
After the system has been flushed to remove debris, determine
if the system needs to be decontaminated. If the system needs to
be decontaminated, it must be done before priming and filling the
pump.
4.6 Priming
The pump should not be run unless it is completely filled with liquid,
as there is danger of damaging some of the pump components.
If the system has suction pressure, follow these steps:
1.
Bleed all air from the pump casing and suction pipe by the
opening of the automatic relief valve at the top of the pump.
2.
Rotate the shaft a few times, if possible, to evacuate any air
trapped inside the impeller passages.
After the stuffing box housing and stuffing box gland reach
approximately the same temperature as the pump parts, the
running-in of the stuffing box gland has been completed. If the
stuffing box leaks too much, tighten it slightly and evenly while the
pump is running. To ensure continuous lubrication, a few drops
should always drip from the stuffing box to protect the packing or
shaft sleeve against damage. See 4.7.1 Recommended packing for
recommendations for leakage rate. If the pump is to be left idle for a
long period of time, we recommend that you replace the packing
before starting the pump.

Do not damage the O-ring (14B) between the shaft
and the sleeve.
Please see the manuals supplied with the accessories.
8.4 Wear ring
Wear rings decrease the clearance between the impeller and volute
to reduce the quantity of liquid leaking from the high-pressure zone,
outlet, and the low-pressure zone, inlet. The rings are designed to
use the pumped liquid for lubrication and to be replaced when worn
to maintain optimal pump performance and service.
As the rings wear, the clearance between the impeller and
the volute increases as does the amount of liquid leaking from the
high-pressure to the low-pressure zone. The rate of wear depends
on the characteristics of the pumped liquid. The pump will typically
have a volute wear ring and can also have an impeller wear ring.
Badly worn wear rings will result in severe degradation of pump
performance: head and flow rate, especially on small
pumps. Examination of wear patterns can provide valuable
information to diagnose pump performance or maintenance issues
and determining the source of a problem.
8.5 Replacing the wear ring
Standard pumps are not supplied with impeller wear rings, and they
can be installed in the field. The wear surface of the impeller is an
integral part of the impeller. Impellers with worn surfaces that
cannot be fitted with wear rings must be replaced.
Use the following steps to determine if the wear rings must be
replaced:
1.
Measure the outer diameter (OD) of the impeller wear surface
or wear ring (8) and the inner diameter (ID) of the volute wear
ring (7).
2.
Compute the diametrical clearance, ID minus OD, and
compare them with the allowed diametrical clearance.
3.
If the measured clearance is out of tolerance, proceed as
follows:
28. Remove the impeller (2) from the shaft.
Use an arbor press. The tolerance for the fit between
the impeller hub inner diameter and shaft outer
diameter is within the ANSI B4.1 [LC] standard.
29. Remove the impeller key (32).
Ensure the ID of the volute ring is concentric with the
wear ring OD, and the surface is smooth.
30. Clean all parts:
a.
Do not clean the bearings. Do not use a metal or
wire brush.
Clean metal parts with a solvent.
a. Replace the volute wear ring and impeller wear ring if the
measured clearance is two times the maximum allowed
clearance.
Machining the impeller wear surface may be
necessary to install or replace the impeller wear
rings. Ensure that the impeller OD is not reduced
and is concentric with the bore of the impeller.
Bronze impeller rings are shrink-fitted onto the hub
according to ANSI B4.1 [FN-4].
Hardened impeller rings are installed according to
ANSI B4.1 [FN-1].
Use a bristle brush.
b. Scrape gasket and lubricant from flanges.
31. Replace or recondition worn or defective parts if the following is
observed:
a. O-rings and bearing cover gaskets have cracks, nicks, or
tears.
b. Packing rings are excessively compressed, fraying or
shredding, or embedded with particles (dirt or metal).
b. Replace the volute wear ring if the measured clearance is
out of tolerance.
8.6 Diametrical clearance
c. Check the entire shaft length for eccentricity with a dial
indicator. Runout must not exceed 0.003 in (0.08 mm).
Clearances are for the standard bronze or cast iron fitted
pumps. For materials with a tendency to gall such as
stainless steel, increase clearances by 0.01 in (0.25 mm).
Mount the shaft between centers or V-blocks on a
level surface.
20
d. Check that threads are clean and sharp.

5.
Align impeller (2) on the shaft and install with an arbor press
or brass tubular sleeve and hammer. When assembled,
the impeller vanes must rotate in the proper direction.
6.
Impeller hub must be centered on shaft journal.
7.
Apply a thread locker on the shaft sleeve, set screws and
install them in the shaft sleeves. Assemble shaft sleeves to the
shaft and hand tighten against the impeller. Tighten the set
screws to a minimum torque of 12 ft-lbs.
Before installation:
1.
Take inventory of the shipment to ensure that the received
parts match the list of parts on your order.
2.
Note the extent of damage or shortage on the freight bill and
bill of lading. Failure to note damage or missing parts may
result in declined warranty or refusing replacement of parts.
3.
It is important that all the pump and system components are
identified and properly stored until installation, see 5.1.4 Longterm storage. There may be many small parts (such as line
shaft couplings or hardware) that are best left in their shipping
container until installation.
8.8 Repairing the product
Visually inspect parts for damage that affects serviceability or
sealing. Pay special attention to mating parts with relative motion,
for example, the wear rings.
Inspection
Perform a detailed inspection as follows:
•
Check O-rings and bearing cover gaskets for cracks, nicks, or
tears.
•
Check packing rings for excessive compression, fraying or
shredding, embedded particles (dirt or metal). Replace them if
they are defective in any way.
•
•
•
Mount the shaft between centers or on V-blocks. Check
for eccentricity throughout the entire length with a dial indicator.
Eccentricity must not exceed 0.003 in (0.08 mm) total
indicator reading.
Mount the shaft between centers or on V-blocks. Check
for eccentricity throughout the entire length with a dial indicator.
Eccentricity must not exceed 0.003 in (0.08 mm) total
indicator reading.
Examine the volute for cracks, dents, gouges or embedded
material.
Repairs
Make needed repairs in the following manner:
•
If the inner diameter (ID) of casing rings (7) is grooved, scored
or eccentric, replace the casing rings.
•
If the impeller wear surfaces or impeller rings (8) are defective,
the impeller must be machined to install new impeller rings. Be
sure machining is concentric with the impeller bore. Use care
NOT to reduce hub outer diameter (OD) when machining off
old impeller rings.
•
Install new impeller rings (8) on the impeller (shrink or press
depending on the material).
•
Replace worn shaft sleeves.
•
Replace shafts having excessive run-out (eccentricity).
8.9 Assembling the pump
Take care not to damage any components and avoid
contamination (dirt, debris, moisture, etc.) of the unit.
Peerless does not recommend reusing gaskets, O-rings,
packing rings, or ball bearings.
1.
Support the pump shaft in blocks and rails to protect it
from bending or being damaged during the re-assembly
process.
2.
Check that the shaft is straight and free of nicks and scratches.
Remove all burrs and scratches with a fine file.
3.
Coat the shaft (6) lightly with oil.
4.
Place impeller key (32) in shaft keyway.
We recommend using Loctite 242 thread locker.
Apply a 360° bead of thread locker to the first few
threads, leaving the first thread-free.
8.
Install the stuffing box bushings (63).
9.
Locate casing rings (7) on the impeller.
10. If casing and or impeller wear rings are required, fit wear
rings into the casing or onto the impeller skirt. Contact Peerless
if rings should be pressed or secured to part as needed. The
final clearance of rings should provide the clearance shown
in the table in section 8.6 Diametrical clearance. If clearance is
not achieved, machine rings before proceeding.
11. Insert board deflectors (40A) on the shaft.
12. If previously removed, install bearing housing seals (169)
into housings (31 and 33).
13. Press housing-bearing-seal assemblies on the shaft to
seat bearings against shaft shoulder fillet.
14. Install bearing retaining ring (18A) in the groove against the
outboard bearing.
15. Install gaskets (73B) on bearing covers. Use factory
supplied parts or cut replacement gaskets from 0.06 in (1.52
mm) No. 444 Vellumoid. (SAEP3415A). EXCEPTION: For all
models using 3306 size outboard bearing, gasket 73B is 0.03
in (0.8 mm).
16. Install outboard deflector (40B) and coupling key (46).
17. Affix the new casing gasket (73A) to the lower casing (1A) with
lubricant.
It is very important that the specified material and
thickness are used for casing gasket. Machined
surfaces of both casings must be perfectly clean and
free from burrs or nicks.
18. For the 12AEF21, follow step a before step b, for all other
models follow step b only:
a. If the bearings bracket has been removed, install it before
setting the rotating element into the lower casing.
b. Use slings around the shaft near the bearings to set the
rotating element into the lower casing.
19. Position the casing rings (7) and both bearing housings so that
all dowel pins engage in slots in the lower case split surface.
20. Assemble both bearing caps per match marks, and tighten
the cap screws.
21. Adjust the shaft sleeves (14 and 14A) to center the impeller
in the lower casing, and tighten both shaft sleeves with
a spanner wrench, then add Locktite to the shaft sleeve
set screws. Then tighten shaft sleeve set screws according
to section 8.2.4 Tightening torques.
22. Cover the top side of the casing gasket with a lubricant.
23. Install the gland bolts (17B). Carefully locate the upper
casing on the lower casing, making certain the dowel pins
engage.

8.7 Inspecting the product
English (US)
24. Install cap screws and tighten working from the center of
the casing to each end, to the torque values in
section 8.2.4 Tightening torques. If any cap screws
require replacement, use only parts with equal or greater
tensile strength. See 8.2.4 Tightening torques.
25. Rotate shaft by hand to check that it turns freely.
26. Push the stuffing box bushings (63) to the rear of the stuffing
boxes.
27. The stuffing box is not packed from the factory, it should be
packed prior to startup according to the guide below.
28. Clean the stuffing box.
29. Check that the packing rings are of proper cross-section and
length.
30. Stagger the joints 90° apart.
31. The rings should butt tightly, but not overlap at the joints.
32. Tamp down the individual packing rings, but not too tightly,
as this may result in burning the packing and scoring the shaft
or shaft sleeve.
33. Where compatible, lightly lubricate the inner and outer packing
diameter with a suitable lubricant. When a lantern ring is
required, make sure that sufficient packing is inserted below
the lantern ring so that the bypass line intersects the packing
container bore adjacent to the lantern ring and is not blocked
by the packing.
34. Replace the water seal piping.
The pipe supplying sealing liquid should be fitted
tightly so that no air enters. If the pumped liquid is
dirty or gritty, clean sealing liquid should be piped to
the stuffing box in order to prevent damage to the
packing and shaft sleeves.
Clear sealing liquid is also required if the stuffing
box materials are not completely compatible with the
pumped liquid. The sealing liquid should be at a
pressure sufficient to ensure a flow of clean liquid into
the pump, but not so high as to require excessive
tightening of the packing.
35. Insert two packing rings, lantern ring (29), if provided, and three
packing rings. Insert each ring separately, and stagger the
joints of successive rings 90°.
36. Insert the packing glands (17), and set the gland bolt
nuts finger tight.
The stuffing box gland must not be too tight during
startup in order to let sufficient liquid lubricate the
shaft and the packing.
37. Rotate shaft by hand to check that it turns freely.
38. Replace all drain plugs if removed during disassembly.
39. Re-lubricate the bearings. See section 4.1 Lubricating the
pump.
40. Make sure that the pump shaft spins freely.
