may remain hot for some time after the unit has
been shut down.
2.4 Material Safety Data Sheet
As a general practice, material safety data sheets (MSDS) are not
supplied with pumps unless required. They may be requested
from Peerless Pump.
2.4.1 Noise level
Use care when touching these surfaces and wear
protective gloves if necessary to touch these
surfaces when hot.
Whenever pump noise level exceeds 85 dBA,
attention must be given to the prevailing health
and safety legislation to limit the exposure of
plant operating personnel to the noise. The usual
approach is to control exposure time to the noise
or to enclose the machine to reduce emitted
Noise levels, especially for diesel engine driven
units, can exceed safe levels. Refer to the noise
level published in the accompanying
documentation, and, if this noise level exceeds
local code or safe levels, place the unit in a
controlled access area and provide ear
protection to personnel authorized to be in this
Fire pump units can start unexpectedly at any
time. Ear protection should be carried by, or
readily available to, all personnel authorized to
be in the pump room with these units.

these gases quickly.
3. Transport and storage
3.1 Transport and handling requirements
The pump has been prepared for shipment at the factory in such
a way as to minimize potential damage due to handling and
The equipment should not be subjected to
excessive g-forces during the handling or
3.2 Receipt and inspection
Receiver should report any shortage or damage to the transport
company handling the shipment and to Peerless Pump.
Prior to installation, take inventory of the shipment to ensure that
the parts received match the list of parts on your order.
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 replacement of parts.
It is important that all the components for a pump unit be
identified and properly stored until installation is to be done.
There may be many small parts (such as line shaft couplings or
hardware) that are best left in their shipping container until
Do not unpack any more than required to verify that the
equipment is complete and undamaged unless installation is to
be done immediately. Check all packaging material that is to be
discarded to verify that no parts or instructions are being
accidentally discarded. In some shipments, small boxes
containing additional parts are bound to pump skids. Leave small
parts in their shipping container until installation so they don't get
lost. Upon unpacking make certain that accessories with a pump
unit are clearly marked showing which pump unit they are to be
used with.
3.4.2 Uncontrolled storage
When pumps are received unassembled, all the parts should be
located close to the location where the pump will be installed.
For uncontrolled storage periods of three months or less, the
equipment is to be inspected weekly to ensure that all
preservatives are intact and internals are protected.
Pump parts that are too heavy to be lifted by
hand must be lifted from the transporting vehicle
with a suitable hoist. Lifting chains or cables
must not contact machined surfaces.

lifting lugs (eyes) of the driver or pump.
Never lift unit using hooks or slings on shafts.
Use proper lifting techniques when manually
lifting components -keep component close to
body, back straight, lift with legs, DO NOT BEND
Do not work under a suspended object unless
you have taken precautions to stop its fall in
event of sling or hoist failure.
3.4 Storage
Standard factory packaging is suitable for protection during
shipment and during covered storage at jobsite for a short period
between installation and startup. The preservatives applied at the
factory have an effective life of two to three months from date of
shipment from factory, depending on the severity of the
environment in which the equipment is exposed. For international
destination this will vary depending on the sea worthiness of
export boxing.
3.4.1 Controlled storage
Storage facilities should be maintained at an even temperature of
at least 10 °F [5.5 °C] above the dew point with relative humidity
lower than 50 % and little or no dust. The equipment is to be
inspected weekly to ensure that all preservatives are intact and
internals are protected.
Inspect and recoat periodically the equipment with water
displacement rust inhibitors (VPCI-368-021, Rust-Ban 392 or
equal), crusting grease (Rust-Ban 326 or equal), vapor phase
inhibitor (Shell VPI-260 or equal) or rust preventative coating
(Rust-Ban 373 or equal).
Protect the equipment from flooding or from
harmful chemical vapors.
Storage should be free from ambient vibration.
Excessive vibration can cause bearing damage.
Precautions should be taken to prevent rodents,
snakes, birds or insect from nesting inside the
Provide a roof or shed shelter to protect from direct exposure to
the elements.
If equipped, connect space heaters on equipment such as
motors, engines or controls.
3.4.3 Standard short-term storage
The pump and equipment, as shipped, have adequate protection
for short-term (two to three months) storage in a covered, dry and
ventilated location at the job site prior to installation.
For short-term (two to three months) storage not in a covered, dry
and ventilated location at the job site prior to installation. For
packed-type pumps, remove stuffing box packing and place it in a
sealed plastic bag. Apply a film of compatible lube oil over the
water displacement rust preventative (Rust-Ban 632 or equal).
Seal the end of the stuffing box with rolled vapor phase inhibitor
paper and seal with weatherproof tape. For packed-type pumps
the packing glands may be left on the pump shaft, but should be
securely fastened in position.
All exposed machined surfaces should be thoroughly coated with
a firm film rust preventative material (Rust-Ban 373 or equal) that
is readily removable with a petroleum distillate product.
All exposed painted surfaces should be dry, clean and free of
grease and other contaminates.
After pump has been thoroughly drained, cover the pump suction
and discharge flanges with a cover (typically cardboard or wood)
to blank off these openings.
Rotate pump shaft per the rotation arrow on pump several
revolutions at least once per week to coat the bearing with
lubricant and to retard oxidation and corrosion, flat spots and
staining. Shaft should end up 90 ° from starting point.
To place the pump in operation, all protective coverings and
coatings should be properly removed. For packed-type pumps,
repack the stuffing box with the proper number of packing rings
from bag. If the packing appears to be damaged or otherwise
unfit, it should be replaced.
See section 3.4.4 Long-term storage when the startup of
equipment is made over three months from the date of shipment
from the factory.
Long-term storage protection from the factory does not extend
the warranty in any manner. Warranty policy is twelve months
from startup or eighteen months from time of shipment, whichever
occurs first. This warranty is valid only if equipment has been
properly handled and stored as per the stated requirements.
Should the equipment be stored or handled improperly, then the
warranty is invalid and may be reinstated only after a factory
representative is allowed to inspect the equipment prior to
startup. Expenses for the representative will be billed in
accordance with the latest schedule for field service engineer.
Any repairs or repair parts needed will be billed to the customer at
prices in effect at time of shipment of these repairs/parts.
At the time of pump specification and/or order placement
Peerless Pump should be advised about the extended storage
duration so that special long-term storage protection can be
provided for the equipment prior to shipping to the job site.
Inspection of the equipment by a factory representative prior to
startup is normally required to ensure equipment integrity and
compliance with warranty requirements.

5.1 Factory support
For customized products, we recommend that you have a
Peerless Pump service engineer supervise installation and
5.3 Foundation
The pump must be installed on a foundation rigid enough to
support the entire weight of the pump plus the weight of the fluid
contained in it. Weak foundations or foundations on unstable
ground can cause misalignment, vibration, and even total
foundation failure.
This is to ensure that the machinery is properly installed. You will
then also have the opportunity to review, and see implemented,
factory-recommended instructions.
This pumping unit is designed to be operated
within certain limits pertaining to fluid pump,
driver conditions, etc. These limits are listed on
the performance curve, or on original contract
Do not operate this pump at any pressure, flow
rate, or liquid temperature other than those for
which the pump was originally purchased. Do not
pump any other liquid than the one for which the
pump was originally purchased without the
consent of Peerless Pump or its authorized
representatives. Disregard of this Warning can
result in pump failure and serious personal injury
or death.
Operation outside of these limits may result in
damage to the unit, personal injury, or death.
Consult your Peerless Pump representative for
approval if a need arises to operate outside of
these limits.
The mass of the foundation should be sufficient, preferably five
times that of the rotating element of the pumping equipment, to
form a permanent and rigid support for the base plate.
Foundation and base plate bolt sizing is critical, particularly on
high-pressure pumps, to adequately restrain reaction forces such
as from directional flow change, system transients and sudden
valve closure. Concrete foundations may have anchor bolts
installed in sleeves that are two times the diameter of the bolt to
allow alignment and should be located by a drawing or template.
Failure to have each component's surface machined will result in
excessive vibration.
Operation at a reduced capacity for prolonged
periods may shorten the useful life of the seals or
packing, shaft sleeves, bearings, and the shaft.
Fire pumps are applied with full knowledge that
operation at reduced capacity will occur.
Follow the instructions in sections 5.4.1 Leveling and
5.4.2 Grouting. After the grout is cured (a minimum of 48 hours),
the pump unit may be finished for pump installation. Peerless
Pump does not recommend installation of the base plate without
the pump.
Locate pump discharge piping and suction piping
as well as auxiliary equipment, control and
starting panels so that adequate access is
provided for maintenance.
Adequate floor space and working room should
also be provided for maintenance
Steel support structures may not be stiff enough
even if their mass exceeds five times that of the
rotating element. A civil engineer should review
and approve a steel support structure before
pump installation.
Whether the base plate is installed prior to the pump installation
or at the same time, the pump must be attached to the base plate.
Check that the pump feet are clean and free of burrs and nicks.
5.2 Location
Allowable bearing loads of structural steel and
floors can be obtained from engineering
handbooks; building codes of local communities
give the recommended allowable bearing loads
for different types of soil.
To minimize frictional head loss, locate the pump
so that it can be installed with a short and direct
discharge pipe and with the least number of
elbows and fittings. If practical, it should be
placed so that it will be accessible for inspection
during operation. Pumps, drivers and controls
should be protected against flooding, freezing,
The suction supply system must provide the
pump with Net Positive Suction Head (NPSH)
equal to or greater than that required by the
pump at any capacity on its operating curve. Ask
your Peerless Pump representative for
assistance if; you do not understand how to
calculate or measure suction supply system
Position the foundation and the foundation bolts
so that pump suction and discharge flanges will
be in accurate alignment with the discharge
5.3.1 Seismic analysis
When pumps are located in seismically active areas and for
certain critical installations the pumps, supports and accessories
should be earthquake-resistant. The design specifications to
achieve earthquake resistance vary, depending upon
geographical area, class of the equipment (defining how critical
the survival of the equipment is) and the characteristics
(acceleration response) of the structure or foundation supporting
the pump.
Complete specifications for earthquake-resistance requirements
should be supplied by the customer. This includes the following:
the seismic criteria, such as acceleration, magnitudes,
frequency spectrum, location and direction relative to pump
the qualification procedure required, i.e., analysis, testing or a
combination of these, and requirements for operability during
and/or after test.
English (US)
5. Installation
Adequate headroom should be provided to accommodate the
pump to be handled, including rigging.
Properly sized slings, chains and shackles
should be available for attaching to the lifting
lugs (eyes). Eyebolts are required for handling
pump sections when lifting lugs are not provided.
5.4.1 Leveling
1. Remove the supporting timbers, rope and any other
equipment from the top of the foundation.
2. Disconnect the coupling halves between the pump and driver.
4. Orient the pump so that the discharge outlet and suction inlet
is in the desired direction and the holes in the base align with
the foundation bolts.
5. Continue to lower the pump until the bolts just enter the holes
in the base.
6. If the foundation is concrete, place the wedges under the base
plate, adjacent to the bolt holes, one under each of the four
7. For structural foundations (made up of I-beams or H-beams),
use shims under the corners.
8. Continue to slowly lower the pump until the base of the base
plate rests on the wedges or anchor bolts with washers and
5.4.2 Grouting
After the base plate is at the correct location and leveled with a
precision level, the base plate needs to be grouted to the
Grout compensates for unevenness in the foundation and base
plate and minimizes vibrations levels during operations. It
prevents the unit from shifting after mounting and alignment.
Cross board for holding
foundation bolts
Accurate alignment of the pump shaft in relation
to the motor shaft is absolutely essential for
smooth and trouble-free operation.
9. By using the wedges or washers and nuts on the anchor bolts,
adjust the pump suction flange center line to the correct
10. While maintaining the correct elevation, adjust the nuts and
washers or shims to achieve the specified levelness of 0.005"
per ft. [0.4 mm per m] in both directions. The levelness should
be measured by placing a precision level on the machined
face of the discharge flange.
11. Place a machinist's level on the discharge flange, orienting it
parallel with one of the edges of the base.
12. Move the wedges or add more shims until the level reading
reaches 0.005" per ft. [0.4 mm per m].

If the base plate is not already grouted in place,
be certain that the grouting dam around the
foundation opening is in place before lowering
the pump assembly onto the foundation.
3. Lower the pump unit until the base plate is just above the
foundation bolts.
Never attempt to align the pump using a spirit
(carpenter's) level.

For typical installations, suitable overhead lifting equipment of
adequate capacity to lift the driver, the entire pump (without
driver) or the heaviest subassembly of the pump should be
available at the job site when installing or removing the pump.
Typical foundation with base plate
Only non-shrinking grouting material should be used for grouting
the base plate to the foundation. Foundation bolts should not be
fully tightened until the grout is hardened, usually about 48 hours
after pouring.
1. Prepare the foundation surface according to the grout
manufacturer's recommendations.
2. Locate the foundation bolts by the use of a template frame
and provide anchorage as shown in fig. 4. See the outline
drawings furnished with each pump for the exact location of
the foundation bolts.
3. Build a dam on the foundation, enclosing an area around the
base plate that includes all alignment wedges. Allow for a
grout thickness of 0.75 to 1.50" thickness [19.05 mm to 38.1
mm]. See fig. 3.
4. Pour the grout through the holes provided in the base plate or
through open ends of steel channel base plates. While
pouring, tamp liberally in order to fill all cavities and prevent
air pockets. If tamping does not eliminate all air pockets, drill
small vent holes through the base surface.
5. Level off the grout flush with the top of the dam.
6. Allow the grout to cure at least 48 hours before tightening the
foundation bolts or starting the pump.
7. Tighten pipe connections to suction and discharge flanges.
8. Check the pump alignment in Section 5.9 Alignment.
9. When the grout has thoroughly dried, paint the exposed
edges to prevent air and moisture from coming in contact with
the grout.
13. Reorient the level on the same surface, 90 ° from the original
14. Again adjust the wedges or shims until a 0.005" [0.12 mm]

5.5.1 Inspection
All pump parts were carefully inspected before leaving the
factory, but may have become soiled or damaged in shipping and
handling or storage at site. The installer must therefore check that
all parts are clean and undamaged before installing them.
Never attempt to lift the pump by means of
eyebolts screwed into the driver mounting holes
because the bolts are not strong enough to carry
the weight of the entire pump.
Do not step or walk on the pump components. Do
not place other parts or equipment on the pump
Use appropriate solvent to wash off any protective coating from
the shaft sections and wipe thoroughly clean and dry.
Dirt, sand, etc. in the system will cause premature wear on the
critical pump internal surfaces, resulting in reduced pump
Pumps and drivers mounted on a common base plate were
accurately aligned before shipment. All base plates are flexible to
some extent and, therefore, must not be relied upon to maintain
the factory alignment.
Realignment is necessary after the complete unit has been
leveled on the foundation and again after the grout has set and
foundation bolts have been tightened. The alignment must be
checked after the unit is piped and rechecked periodically as
outlined in the following paragraphs. To facilitate accurate field
alignment, we do not dowel the pumps or drivers on the base
plates before shipment.
5.5.2 Engine Preparation
Safe and efficient operation of a pumping unit driven by an diesel
engine, requires the installation to satisfy the following
1. It is recommended that the operator become familiar with the
installation and service manual supplied by the engine
manufacturer or Peerless Pump
2. Be well ventilated in order to keep the ambient temperature as
low as possible. Taking 60 °F [15.6 °C] as a datum point,
every 10 °F [-12 °C] rise in temperature reduces the
horsepower of the engine by approximately 1 %.
3. Provide ample air for proper combustion.
4. Provide the engine with an efficient exhaust system so that
the combustion gasses discharge with a minimum of
5. Provide for a fuel system of adequate capacity that meets the
local codes.
5.6.1 Leveling
Flat surfaces that might capture air during grouting should be
vented to prevent voids between the surface and the grout.
The base plate should be leveled by use of wedges (see section
5.4.1 Leveling) or by use of leveling screws supported on
rectangular metal blocks.
The leveling screw threads should be covered with a non-binding
material such as grease, putty or tape before grouting, to facilitate
their removal.
If shims are used, they should be placed to isolate from the initial
application of grout. After the initial grout has cured, the forms
and shims may be removed and the void filled with a second
application of grout.
A gap of about 0.75 to 1.5" [19.05 mm to 38.1 mm] should be
allowed between the base plate and the foundation for grouting.
See section 5.2 Location.
5.6.2 Grouting
The grout material that supports the base plate is a critical
element of the pump support structure and should be carefully
selected. The product warranty is void if this Instruction is not
If the grout cracks or fails, the structure will be compromised.
When the alignment is correct, the foundation bolts should be
tightened evenly but not too firmly. The unit can then be grouted
to the foundation. It is not recommended to grout leveling pieces,
shims or wedges in place because they introduce discontinuities
and stress concentrations that may cause the grout to crack.
Foundation bolts should not be fully tightened until the grout is
hardened, usually about 48 to 72 hours after pouring. Jacking
screws should be removed after the grout has hardened and the
holes filled with an appropriate sealing material.
Do not distort the base plate by over tightening
the foundation bolts.
5.6.3 Doweling
Contact Peerless Pump for further information.
6. Provide ample accessibility to service engine.
7. Provide correct rotation of the pump. Engine rotation is
determined at the factory. No change of engine rotation can
be made in the field.

5.5 Installation preparations
5.7.1 Pipe supports, anchors or joints
Suction and discharge piping should be anchored, supported and
restrained near the pump to avoid application of forces and
moments to the pump in excess of those permitted by Peerless
Do not exceed the forces or moments specified
on the outline drawing when connecting piping to
the suction or discharge flanges.
In order to achieve optimum operation and minimum noise and
vibration, consider vibration dampening of the pump.
Piping must be independently supported and
arranged so that expansion and contraction, due
to temperature changes, will not cause
Noise and vibration are generated by the revolutions of the motor
and pump and by the flow in pipes and fittings. The effect on the
environment is subjective and depends on correct installation and
the state of the remaining system.
Elimination of noise and vibrations is best achieved by means of
a concrete foundation, vibration dampers and expansion joints.
The selection of vibration damper differs from installation to
installation. In certain cases, a wrong damper may increase the
vibration level. Vibration dampers should therefore be sized by
the supplier of the vibration dampers.
If you install the pump on a foundation with vibration dampers,
always fit expansion joints on the pump flanges. This is important
to prevent the pump from "hanging" in the flanges.
5.7.3 Suction piping
The suction and discharge piping should be of sufficient size and
be internally free of foreign material.
Considerations for suction piping to achieve optimal performance
Piping should be cleaned mechanically and
chemically, and flushed prior to installing the
pump. A large number of pump packing, seal and
seizure troubles are due to improperly cleaned
The pump should also be inspected internally for foreign matter
that may have entered the pump.
1. When operating under suction lift, line must be kept absolutely
free from air leaks.
2. When operating under suction lift, must be at least one pipe
diameter larger than the pump suction nozzle. In order to
prevent eddies and vortices, the end of the suction pipe must
be at least two pipe diameters below the free liquid surface. If
a foot valve is used to facilitate priming, the foot valve must
have a minimum flow area 1.5 times the area of the suction
pipe. The suction at all points and should not contain loops or
high spots in which air can be trapped.
3. When operating under suction pressure, pipe may be equal
to, but never less than the suction nozzle size.
Failure of the suction piping to deliver the liquid to the pump in
this condition can lead to noisy operation, swirling of liquid
around the suspended pump assembly, premature bearing failure
and cavitation damage to the impeller and inlet portions of the
Contact Peerless Pump for further information.
5.7.4 Suction valves and manifolds
Air pocket
Block valves may be installed to isolate the pump for
Foot valves are specially designed non-return valves sometimes
used at the inlet to prevent backspin caused by rapidly draining
water in the discharge pipe.
Path of water
5.7.5 Discharge valves
Air pocket
A non-return valve and an isolation valve should be installed in
the discharge pipe. The non-return valve serves to protect the
pump from backflow and excessive backpressure. The isolation
valve is used when starting and stopping the pump.
We recommend closing the isolation valve before stopping or
starting the pump.

5.7 Piping and connections
Piping Arrangement
Pump backspin and hydraulic shock can cause severe damage to
pump and motor. Install at least one non-return valve in the
discharge pipe, not more than 25 ft. [7.5 m] after the discharge
flange to help prevent this
Operating some pumps at shutoff may cause a dangerous
increase in pressure or power. If increasers are used on the
discharge side of the pump to increase the size of piping, they
should be placed between the non-return valve and the pump.
5.7.2 Vibration dampers
If expansion joints are used, they should be placed between the
pipe anchor and the non-return valve.
To prevent the transmission of vibrations to buildings, isolate the
pump foundation from building parts by means of vibration
5.7.6 Nozzle loads
The selection of the right vibration damper requires the following
The piping should be aligned with the pump nozzles to minimize
pump nozzle loads. Contact Peerless Pump for allowable nozzle
loading for your given design.
forces transmitted through the damper
5.8 Setting the impeller clearance
motor speed considering speed control, if any
required dampening in %.
To achieve optimal performance and reduce radial loading, the
impeller should be centered in the volute passageway of the
casing. For new pumps, this is done at the factory, refer to section
7.6 Wear Ring.
Pumps and drivers mounted on a common base plate were
accurately aligned before shipment. All base plates are flexible to
some extent and, therefore, must not be relied upon to maintain
the factory alignment.
After the grout has set and the foundation bolts have been
properly tightened, the unit alignment should be checked.
After the piping of the unit has been connected, the alignment
should be checked again. Alignment may be checked by
mounting a dial indicator to measure shaft movement before and
after tightening flange bolts. If the unit does not stay in alignment
after being properly installed, the following are possible causes:
English (US)
5.9 Alignment
Misalignment may be the cause of:
Noisy pump operation
Premature bearing failure
Excessive coupling wear
Recheck alignment is required after:
Grout has hardened
Foundation bolts are tightened or readjusted
Piping is connected or adjusted
setting, seasoning or springing of the foundation
Pump, driver or base plate is moved for any reason
excessive pipe strain distorting or shifting the machine
settling of the building
shifting of pump or driver on the base plate or foundation
The procedure for alignment verification for units with the pump
and driver connected by a flexible coupling, mounted on a
common base are:
To facilitate accurate field alignment, we do not dowel the pumps
or drivers on the base plates before shipment.
Reliable, trouble-free, and efficient operation of a pumping unit
requires correct alignment of pump and driver shafts.
1. Disconnect the coupling halves.
2. Set the coupling gap to the dimension shown in fig. 6, 7, or on
outline drawings.

3. Test for parallel and angular alignment with a straight edge
and feeler gauge as shown in manufacturer's instructions (at
the end of this section). With coupling halves stationary, make
trials at four places 90 ° apart. Perfect alignment occurs when
a straight edge is level across the coupling halves and the
same gauge just enters between the halves, both conditions
at all points.
4. An alternate test for parallel and angular alignment may be
made with a dial indicator mounted as shown in fig. 8.
Scribe the index lines on the coupling halves (as shown) or
mark where the indicator point rests.
Set indicator dial to zero.
Slowly turn BOTH coupling halves so that index lines match,
or indicator point is always on the mark.
Observe dial reading to determine whether pump or driver
needs adjustment.
Acceptable parallel and angular alignment occurs 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

5. When significant operating temperature differential will exist
between the pump and driver (i.e. steam turbine drive with
pump handling cold liquid), thermal growth will cause the
hotter unit to rise. Compensate for this growth by initially
setting the hotter unit 0.003" to 0.005" [0.076 mm to 0.127
mm] low. When both units are at normal operating
temperature, a final check of coupling alignment must be
made. Correct the alignment if necessary.
6. NOTE Check for correct electric motor rotation as described in
the two bullet points under paragraph 6.3 below while
coupling halves are disconnected.
7. 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 after each
shifting of a wedge.
8. In some instances, for factory-aligned pumping units, it may
be necessary to change the shims under the pump or driver,
or even relocate these factory-positioned units on the base
plate. Make such changes only after it is certain alignment
cannot be obtained by shifting of the wedges.
9. If wedges are shifted or shims changed a substantial amount
to obtain proper alignment, recheck the piping alignment and
level of the shafts.

6.1 Frost protection
5.10 Lubrication, priming and cooling systems
If the pump is to be used in area where there is a potential of

lubrication fitting at packing (if applicable)
lubrication for pump bearing
A plot of speed versus torque requirements during the starting
phase of a pump can be checked against the speed versus
torque curve of the driving motor. Contact the drive manufacture
for curve availability. The driver should be capable of supplying
more torque at each speed than required by the pump in order to
accelerate the pump up to rated speed. This condition is
generally easily attainable with standard induction or
synchronous motors, but under certain conditions, such as highspecific-speed pumps over 5000 US units [100 metric units] or
reduced voltage starting, a motor with high pull-in torque may be
required. To achieve a smooth start for the pumping equipment,
autotransformers may be connected to the starting panel or solid
state starters used. These provide a gradual increase in voltage
up to rated voltage, ensuring even acceleration.
lubrication of the driver
5.12 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.
5.12.1 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 normal pump operation.
If the driver offers little resistance while running backwards, the
rotational speed may approach the pump-specific speed.
This condition is called runaway speed and causes mechanical
problems. Contact Peerless Pump for aid in preventing this

Good practice includes the following:
Keep lubricant clean. Provide, and use, a dust tight cover on
the storage container.
Use the oldest lubricant first.
Clean pump lubricant fittings before re-lubricating with grease.
Use clean dispensing equipment.
Remove 0.25" [6.4 mm] drain pipe plug on bottom outside of
bearing housing cover. Inject clean, new grease, forcing out
the old through the drain opening.
Start and run the pump for a short time to eject any excess
grease. Reinstall 0.25" [6.4 mm] pipe plug. Wipe off ejected
Use the proper amount of lubricant -too much result 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 approximately 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.

Prior to checking rotation ensure the power is disconnected and
locked out to prevent accidental energizing of the driver.
Disconnect the coupling so that the motor shaft can spin without
driving or contacting the pump shaft.
Rotate the motor by hand in both directions to check freedom
without binding. Momentarily energize the motor to check that
rotation is in the same direction as the arrow on the pump. If
motor is three-phase type, reverse rotation (if required) by interchanging any two of the three power leads. The rotation of most
single-phase motors is fixed by internal wiring and cannot be
easily changed.
After proper rotation has been confirmed, reconnect coupling and

6.5 Check list
6.5.1 System flushing
When the pump is installed in the completed piping system, we
recommend to backflush the system to remove debris such as
stubs of welding rod, welding slag and loose scale. The pump and
other sensitive part should be protected with startup strainers,
which should in turn be removed upon completion of the flushing
6.5.2 System decontamination
After the system has been flushed to remove debris, determine if
your system needs to be decontaminated. If so, do that before
priming and filling.
6.5.3 Priming
The pump should not be run unless it is completely filled with
liquid, as there is danger of damaging some of the pump
If the system has suction pressure, bleed all air from the pump
casing and suction pipe by the opening of the automatic relief
valve at the top of the pump. Rotate the shaft a few times if
possible to evacuate any air trapped inside the impeller
The function of a stuffing box is to limit or eliminate leakage of the
pumped fluid and to prevent air from entering along the shaft.
Pumps are equipped with packing seals. These instructions are
intended for pumping units handling water.
Packed Type Seal
A packed type stuffing box must correspond to the suction
conditions of the installation. The pump is shipped with the
packing installed unless otherwise specified by the customer.
Check the packing carefully, allowing a slight leakage for
lubrication. Never force the packing into a leak-proof position
since this will create excessive friction and cause damage to the
packing or shaft sleeve. Maximum packing life can be expected
when the leakage approximates a minimum of 40-60 drops per
minute. A reduction of leakage considerably reduces the life of
both the packing and shaft sleeve. If leakage is excessive, tighten
the gland bolts evenly, about 1/6 of a turn at a time. Do not be
confused if the leakage seems to increase after and adjustment
of the packing has been made. The leakage will normally reduce
after a period of time as the packing adjusts itself to its new
position. It should be kept in mind that it takes time for newly
installed packing to "run-in" and that during this initial period,
frequent attention and adjustments are necessary. It sometimes
takes several days to achieve the desired results. Peerless Pump
recommends the use of lantern rings and water seal lines.
Once the stuffing box housing and stuffing box gland have
reached approximately the same temperature as that of the pump
parts, the running-in of the stuffing box gland has been
completed. If the stuffing box leaks too much, retighten slightly
and evenly while the pump is running. To ensure continuous
lubrication, a few drops should always drop from the stuffing box
to protect the packing or shaft sleeve against damage, see chart
for recommendations for drop rate.
When the leakage can no longer be controlled by adjusting the
gland, all rings of packing should be replaced. The addition of a
single ring to restore gland adjustment is not recommended.
If the pump is to be left idle for a long period of time, we
recommend to replace the packing prior to restarting the pump 1.
6.6 Startup, operation and shutdown
Prior to making an initial start, after installation or major
maintenance check the following:
Correct installation and rotation of driver.
Coupling alignment.
Bearing lubrication on pump and driver.
Proper lubrication for stuffing boxes. For pumps having
mechanical shaft seals, make certain that the liquid
temperature, pressure, cooling and lubrication of seal faces all
meet the manufacturer's requirements
Gauges (if used) of correct range and in good condition.
All foundation, pump, and driver bolts properly tightened. All
external fasteners (nuts, bolts, screws) on pump checked
against recommended torque values.
When possible, turn the pump shaft by hand to make sure that
parts do not bind.
Ensure the suction valve is fully open.

Refer to local fire code.
After the pump has run a reasonable time, measure the
temperature of bearing and stuffing box housings. The
temperature of the stuffing box should approximate that of the
pumped liquid. If it is to hot (overheats), the packing is too tight
and should be checked.
6.6.1 Air in system
Entrained air reduces pump total head and flow rate. To avoid air
in the system, take these precautions:
All UL/ULC listed fire pumps will have water seal piping only
when suction pressure is less than 30 psiG [2.1 bar].
All FM approved fire pumps will have water seal piping regardless
of the suction pressure.
See supplemental instruction 4850332 for high-pressure fire
pump applications.
Return lines into tanks should terminate a minimum of two
pipe diameters below the low liquid level.
6.6.2 Lubrication system
Before running the drivers, either separately or connected to the
pump, check lubrication requirements in the instructions of the
driver. Check that the following points have been fulfilled:
Grease-lubricated bearings have been properly greased with
the driver manufacturer's recommended grade.
6.6.3 Driver settings
Follow the instructions of the manufacturer.
6.6.4 Performance testing
The stuffing box gland must not be too tight
during startup in order to let sufficient liquid
lubricate the shaft and the packing.
Once the unit is energized, check operating speed, flow rate,
suction and discharge pressure, and power input. While it may
not be possible to exactly repeat the factory performance, initial
field test data becomes a valuable baseline for future checking to
determine possible wear and need to perform maintenance.
Auxiliary piping and gasket joints should be checked for leaks and
proper makeup.

products that are corrosive in nature.
12. Remove coupling key (46), and outboard deflector (40B).
If you elect to use heat to remove the part, it must
be applied with great care. Before applying heat,
ensure any residual hazardous liquid trapped
between the two parts is thoroughly drained out
to prevent an explosion or emission of toxic
vapor. Impeller design varies and so does the
amount heat and the duration of heat application
required to loosen the impeller.
Contact Peerless Pump for help in removal of
Before opening the terminal box of an electric
motor, make sure that the power supply has been
switched off.
Before starting disassembly of the pump, it is recommended that
a set of spare parts as shown in section 7.2 Recommended spare
parts be obtained. Peerless Pump does not recommend reuse of
gaskets, O-rings, packing rings, or ball bearings.
1. Shut down pump.

7.6 Wear Ring
7.7 Inspection and Repair
Wear rings provide a close-running, renewable clearance to
reduce the quantity of liquid leaking from the high-pressure side
to the suction side. These rings depend on the liquid in the pump
for lubrication. They will eventually wear so that the clearance
becomes greater and more liquid passes into the suction. This
rate of wear depends on the characteristics of the liquid pumped.
Badly worn wear rings will result in severe degradation of pump
head and flow rate, particularly on small pumps. Examination of
wear patterns can provide valuable information in diagnosing
pump problems and determining their origin.
Inspection. Visually inspect parts for damage affecting
serviceability or sealing. Emphasize inspection of mating parts
having relative motion- wear rings, for example. Perform detail
inspection as follows:
Worn wear rings or surfaces can be replaced to restore hydraulic
Standard pumps are furnished without impeller
rings; the wear surface is an integral part of the
impeller. Impeller wear rings maybe field installed
by machining. Refer to note following paragraph
2-2b for standard fits to be produced when
making such repair. Replace impellers which
cannot be salvaged by such repair.
Measure the OD of the impeller wear surface or impeller ring (8)
and the ID of the casing ring (7). Compute the diametrical
clearance (ID minus OD) and compare with the limits below. If
measured diametrical clearance exceeds two times values, repair
or replace to restore design clearance. ID surface of casing ring
must be smooth and concentric with ring OD.

Clearances in are for standard bronze or cast
iron fitted pumps. For materials with a tendency
to gall, such as stainless steel, increase
clearances by 0.010" [0.25 mm].
For bronze impellers and rings, the rings are
shrunk on the hub according to standard fit FN-4
of ANSIB4.1. Hardened impeller rings are
installed according to ANSI B4.1 standard fit
If impeller clearance is found to be out of tolerance, replace
casing wear ring. It may be necessary to consider machining
impeller wear surface for wear ring installation (if not originally
supplied) to return to approved clearance. If the impeller must be
machined to install new impeller rings, be sure machining is
concentric with impeller bore.
Use care not to reduce impeller hub OD when
machining off old impeller rings.
1. Check O-rings and bearing cover gaskets for cracks, nicks, or
tears; packing rings for excessive compression, fraying or
shredding, embedded particles (dirt or metal). Replace if
defective in any way.
2. Mount the shaft between centers or on vee blocks. Check for
eccentricity throughout entire length with a dial indicator;
eccentricity must not exceed 0.003" [0.08 mm] total indicator
reading. Check that threads are clean and sharp. Surfaces, on
which bearings mount must be smooth, have a finish of 32 µin
[0.81 µm] or better, and the shoulders square and free from
3. Examine impeller passages for cracks, dents, gouges or
embedded material.
Repair. Make needed repairs in the following manner:
1. If ID of casing rings (7) is grooved, scored or eccentric,
replace the casing rings.
2. If 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 impeller bore. Use care
NOT to reduce hub OD when machining off old impeller rings.
3. Install new impeller rings (8) on the impeller (shrink or press
depending on material).
4. Replace worn shaft sleeves.
5. Replace shafts having excessive run-out (eccentricity).
Take care not to damage any components and
avoid contamination (dirt, debris, moisture, etc.)
of the unit.
See section 7.4 Tightening torques for torque values.
1. Support 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 with a fine file all burrs and scratches.
3. Coat the shaft (6) lightly with oil.
4. Place impeller key (32) in shaft key way.
5. Align impeller (2) on shaft and install with an arbor press or
brass tubular sleeve and hammer. When assembled, the
impeller vanes must rotate in the proper direction.
Impeller hub must be centered on shaft journal.
7. Install shaft sleeve set screws in shaft sleeves. Assemble
shaft sleeves to the shaft and hand tighten against the
impeller. Do not tighten shaft sleeve set screws.
8. Install the stuffing box bushings (63).
9. Locate casing rings (7) on impeller.
10. If casing and or impeller wear rings are required, fit wear rings
into the casing or onto the impeller skirt. Contact Peerless
Pump if rings should be pressed or secured to part as needed.
Rings final clearance should provide the clearance shown in
the table in section 7.6 Wear Ring. If clearance is not
achieved, machine rings prior to proceeding.
11. Place in board deflectors (40A) on shaft.
12. If previously removed, install bearing housing seals (169) into
housings (31 and 33).
13. Press housing-bearing-seal assemblies on shaft to seat
bearings against shaft shoulders.
14. Install bearing retaining ring (18A) in groove against the out
board bearing.
15. Install gaskets (73B) on bearing covers. Use factory supplied
parts or cut replacement gaskets from 0.06" [1.52 mm] No.
444 Vellumoid. (SAEP3415A).
EXCEPTION: For all models using 3306 size outboard bearing,
gasket 73B is 0.03" [0.8 mm].
16. Attach in board and outboard bearing covers (35 and 37). In
the assembled position, the greased rain tap must be located
at bottom in a horizontal plane.
22. Adjust the shaft sleeves (14 and 14A) to center the impeller in
the lower casing volute, 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 7.4 Tightening torques.
23. Cover the top side of the casing gasket with a mixture of
graphite and oil.
24. Install the gland bolts (17B). Carefully locate the upper casing
on the lower, making certain the dowel pins engage.
25. Install cap screws and tighten working from the center of the
casing to each end, to the torque values in section
7.4 Tightening torques. If any cap screws require
replacement, use only parts with equal or greater tensile
strength. See 7.4 Tightening torques.
26. Rotate shaft by hand to check that it turns freely.
27. Push the stuffing box bushings (63) to the rear of the stuffing
28. I If the stuffing box is not packed from factory, it should be
packed prior to startup following the below guide.
29. Clean the stuffing box.
30. Check that the packing rings are of proper cross-section and
31. Stagger the joints 90° apart.
32. The rings should butt tightly but not overlap at the joints.
33. 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.
34. 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 placed in
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.
35. The pipe supplying sealing liquid should be fitted tightly so
that no air enters. If the liquid to be pumped 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.
36. Clear sealing liquid is also required if the stuffing box
materials are not completely compatible with the pump 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.
17. Install outboard deflector (40B), and coupling key (46);
assemble coupling half on the shaft and tighten the setscrews.
37. Insert two packing rings, lantern ring (29) if provided, and
three packing rings. Insert each ring separately and stagger
the joints of successive rings 90degrees.
18. Affix the new casing gasket (73A) to the lower casing (1A)
with shellac.
38. Insert the packing glands (17) and set the gland bolt nuts
finger tight.
It is very important that specified material and
thickness be used for casing gasket. Machined
surfaces of both casings must be perfectly clean
and free from burrs or nicks.
The stuffing box gland must not be too tight
during startup in order to let sufficient liquid
lubricate the shaft and the packing.
39. Rotate shaft by hand to check that it turns freely.
19. Use slings around the shaft near bearings to set rotating
element into lower casing.
40. Replace all drain plugs if removed during disassembly.
20. Position the casing rings (7) and both bearing housings so
that all dowel pins engage in slots in the lower case split
42. Make sure that the pump shaft spins freely.
21. Assemble both bearing caps per match marks and tighten the
cap screws.
