SAFETY WARNINGS
Specific to pumping equipment, significant risks bear reinforcement above and beyond normal safety precautions.
WARNING
A pump is a pressure vessel with rotating parts that can be hazardous. Any pressure vessel can explode,
rupture, or discharge its contents if sufficiently over pressurized causing death, personal injury, property
damage, and/or damage to the environment. All necessary measures must be taken to ensure over
pressurization does not occur.
WARNING
Operation of any pumping system with a blocked suction and discharge must be avoided in all cases.
Operation, even for a brief period under these conditions, can cause superheating of enclosed pumpage and
result in a violent explosion. All necessary measures must be taken by the end user to ensure this condition is
avoided.
WARNING
The pump may handle hazardous and/or toxic fluids. Care must be taken to identify the contents of the pump
and eliminate the possibility of exposure, particularly if hazardous and/or toxic. Potential hazards include, but
are not limited to, high temperature, flammable, acidic, caustic, explosive, and other risks.
WARNING
Pumping equipment Instruction, Operation, and Maintenance manuals clearly identify accepted methods for
disassembling pumping units. These methods must be adhered to. Specifically, applying heat to impellers
and/or impeller retaining devices to aid in their removal is strictly forbidden. Trapped liquid can rapidly
expand and result in a violent explosion and injury.
ITT Goulds Pumps will not accept responsibility for physical injury, damage, or delays caused by a failure to
observe the instructions for installation, operation, and maintenance contained in this Pump Safety Manual or the
current IOM available at www.gouldspumps.com/literature.

PUMP DESCRIPTION
The Model 3298 is a sealless close coupled or frame
mounted centrifugal pump with an enclosed impeller that is
driven by a synchronous magnetic coupling and meets
dimensional standards of ANSI B73.1. (The 1x1 1 2-5 is not
ANSI dimensional.)
Rear Impeller Wear Ring - is standard on M and L group
size pumps and is not required on S group sizes. The wear
ring is pressed into the rear of the impeller assembly. The
wear ring reduces axial thrust in the M and L group size
pumps.
The SP 3298 is a self-priming sealless close coupled or
frame mounted centrifugal pump with an enclosed impeller
that is driven by a synchronous magnetic coupling. The
pump and frame / adapter feet locations meet ANSI B73.1
dimensional standards.
Magnetic Coupling - is a coaxial synchronous type using
rare earth magnets. This concept results in a compact
design and allows the impeller to turn at the same speed as
the motor, (i.e. there is no slip between the drive and driven
magnets.)
The V 3298 is a vertical in-line sealless close coupled
centrifugal pump with an enclosed impeller that is driven
by a synchronous magnetic coupling and meets the
dimensional standards of ANSI B73.2.
Magnets - Neodymium Iron (NdFe).
Casing - The casings are one piece cast ductile iron lined
with 1/8" TEFZEL®1 and have ANSI class 150 flanges with
a TEFZEL® raised face. The 3298 and SP 3298 are end
suction, top centerline discharge and are self-venting. The
V 3298 is side suction, side discharge and is also
self-venting.
Impeller Magnet Assembly - The 3298 family utilizes a
one or two piece impeller magnet assembly. The magnet
ring is balanced to ISO 1940 G6.3 levels and is sealed
within the solid enclosed TEFZEL® impeller magnet
assembly.
Stationary Shaft - The impeller magnet assembly rotates
about a solid stationary silicon carbide shaft. The shaft is
supported at one end by the containment shell and the other
end by the TEFZEL® bearing spider.
Containment Shell - isolates the pumped liquid from the
atmosphere. The containment shell construction is backed
with vinylester FRP.
Radial Bearings and Thrust Bearings - Goulds standard
bearing material is carbon with optional Pure Sintered
Alpha Grade Silicon Carbide or DryGuard™ Pure Sintered
Alpha Grade Silicon Carbide.
Standard Close Coupled Mounting - The drive magnet
assembly is keyed, set screwed and mounted directly to the
motor shaft. This arrangement eliminates the need to
perform pump/motor alignment.
3
Optional Power End - The standard configuration is cast
iron with flood oil lubricated ball bearings. Pure oil mist
systems are available as an option. For protection and
reliability of the bearings and the lubricant, a labyrinth seal
is provided. On the inboard side a lip seal is used to prevent
leakage of oil into the magnetic drive assembly.
Bearing Spider - The bearing spider constructed from
solid TEFZEL® houses one of the key silicon carbide thrust
bearings in the pump and supports the stationary shaft at
one end.

following installation instructions.
BASEPLATE INSPECTION
1.
Remove all equipment.
3.
2.
Completely clean the underside of baseplate. It is
sometimes necessary to coat the underside of the
baseplate with an epoxy. This may have been
purchased as an option.
Remove the rust preventative solution from the
machined pads with an appropriate solution.
SITE / FOUNDATION
A pump should be located near the supply of liquid and
have adequate space for operation, maintenance, and
inspection.
Baseplate mounted pumps are normally grouted to a
concrete foundation, which has been poured on a solid
footing. The foundation must be able to
3298 Family Rev. 5/08
absorb any vibration and to form a permanent, rigid
support for the pumping unit.
The location and size of the foundation bolts are shown on
the outline assembly drawing, provided with the pump data
package.
15
equipment being installed must be properly
! All
grounded to prevent unexpected static electric
discharge. This includes ensuring that the PFA
lined pumps are pumping fluids that are conductive.
If not, a static electric discharge may occur when the
pump is drained and disassembled for maintenance
purposes.
Foundation bolts commonly used are sleeve type (Fig. 10)
and J type (Fig. 11). Both designs permit movement for
final bolt adjustment.
1.
Inspect foundation for dust, dirt, oil, chips, water, etc.
and remove any contaminants. Do not use oil-based
cleaners as grout will not bond to it.
2.
Prepare the foundation in accordance with the grout
manufacturer’s recommendations.

2.
Place two sets of wedges or shims on the foundation,
one set on each side of every foundation bolt
(Fig. 12, 13). The wedges should extend .75 in.
(20 mm) to 1.5 in. (40 mm) above the foundation, to
allow for adequate grouting. This will provide even
support for the baseplate once it is grouted.
3.
Carefully lower baseplate onto foundation bolts.
4.
Level baseplate to within .125 in.(3mm) over the length of
the base and .062 in. (1.5 mm) over the width of the base by
adjusting shims or wedges.
5.
Hand tighten bolts.
Remove water and/or debris from anchor bolt
holes/sleeves. If the sleeve type bolts are being used,
fill the sleeves with rags to prevent grout from
entering.

unintended contact of rotating parts. Follow
coupling manufacturer's coupling installation and
operation procedures.
To remove guard, refer to coupling guard assembly/
disassembly instructions.
The points at which alignment is checked and adjusted are:
·
·
Initial Alignment is done prior to operation when
the pump and the driver are at ambient temperature.
Final Alignment is done after operation when the
pump and driver are at operating temperature.
Alignment is achieved by adding or removing shims from
under the feet of the driver and shifting equipment
horizontally as needed.
NOTE: Proper alignment is the responsibility of the
installer of the unit.
Accurate alignment of the equipment must be attained.
Trouble-free operation can be accomplished by following
these procedures:
ALIGNMENT CHECKS
Final Alignment (Hot Alignment)
· After First Run - To obtain correct alignment when both
pump and driver are at operating temperature.
Thereafter, alignment should be checked periodically in
accordance with plant operating and maintenance
procedures.
NOTE: Alignment check must be made if process
temperature changes, piping changes, and/or pump
service is performed.
3
ALIGNMENT CRITERIA
Good alignment is achieved when the dial indicator
readings as specified in the alignment procedure are .002
in. (.05 mm) Total Indicated Reading (T.I.R.) or less when
the pump and driver are at operating temperature (Final
Alignment).
During the installation phase, however, it is necessary to
set the parallel alignment in the vertical direction to a
different criteria due to differences in expansion rates of
the pump and driver. Table 2 below shows recommended
cold settings for electric motor driven pumps based on
different pumpage temperatures. Driver manufacturers
should be consulted for recommended cold settings for
other types of drivers (steam turbines, engines, etc.).

REMEDY
Loosen pump hold down bolts and slide pump and driver
until horizontal alignment is achieved.
Determine if center of baseplate should be raised or
lowered and correct by evenly adding or removing shims
at the center of the baseplate.
NOTE: With experience, the installer will understand
the interaction between angular and parallel and will
make corrections appropriately.
GROUT BASEPLATE
1.
Clean areas of baseplate that will contact grout. Do not
use an oil-based cleaner because grout will not bond to it.
2.
Build a dam around foundation (Fig. 22). Thoroughly
wet foundation.
3.
Pour grout through grout hole in baseplate up to level of
dam. Remove air bubbles from grout as it is poured by
puddling, using a vibrator, or pumping the grout into
place. Non-shrink grout is recommended (Fig. 22).
4.
Allow grout to set.
5.
Fill remainder of baseplate with grout. Remove air as
before (Fig. 23).
Fig. 23
Fig. 22
6.
Allow grout to set at least 48 hours.
7.
Tighten foundation bolts.
ALIGNMENT CHECK
Re-check alignment before continuing, using methods
previously described.

3298 Family Rev. 5/08
PIPING
Guidelines for piping are given in the Centrifugal Pump
section of the “Hydraulic Institute Standards” and should
be reviewed prior to pump installation.
A ▲
!
WARNING
Never draw piping into place by forcing at the flanged
connections of the pump. This will impose dangerous
strains on the unit and cause misalignment between
pump and driver. Pipe strain can adversely effect the
operation of the pump. That could result in serious
personal injury and damage to equipment.
loads from the piping system, including
! Flange
those from thermal expansion of the piping, must
not exceed the limits of the pump. Casing deforma-
3
tion can result in contact with rotating parts and
result in excess heat generation, sparks and
premature failure.
Fig. 25
1.
All piping must be supported independently and must
line up naturally with the pump flanges.
2.
Piping runs shall be designed to minimize friction
losses.
5.
DO NOT make final connection of piping to pump
until grout has hardened and pump and driver
hold-down bolts have been tightened.
The piping should be arranged to allow pump flushing
prior to removal of the unit on services handling
corrosive liquids.
6.
System should be thoroughly cleaned prior to
installation.
3.
4.
It is suggested that expansion loops or joints, if used,
be properly installed in suction and/or discharge lines
when handling liquids at elevated temperatures, so
linear expansion of piping will not draw pump out of
alignment (Fig. 24 & 25).
SUCTION PIPING
A ▲
!
WARNING
NPSHA must always exceed NPSHR as shown on
Goulds performance curves received with order.
Reference Hydraulic Institute for NPSH and pipe
friction values needed to evaluate suction piping.
Properly installed suction piping is a necessity for trouble
free pump operation. Suction piping should be flushed
BEFORE connection to the pump.
1.
Use of elbows close to the pump suction flange should
be avoided. There should be a minimum of 2 pipe
diameters of straight pipe between the elbow and
suction inlet. Where used, elbows should be long
radius (Fig. 26)
Fig. 24
3298 Family Rev. 5/08
23
CORRECT
CORRECT PIPING
Fig. 26
Fig. 28
Suction Lift Conditions
1. Suction pipe must be free from air pockets
Fig. 27
2.
3.
Use suction pipe one or two sizes larger than the pump
suction, with a reducer at the suction flange. Suction
piping should never be of smaller diameter than the
pump suction.
Reducers should be eccentric at the pump suction
flange with sloping side down and horizontal side at
the top (Figs. 26, 27, 28).
$
CAUTION
2.
Suction piping must slope upwards to pump.
3.
All joints must be air tight.
4.
A means of priming the pump must be provided, such
as a foot valve, except for the self priming pump.
Suction Head/Flooded Suction Conditions
1. An isolation valve should be installed in the suction
line at least two pipe diameters from the suction to
permit closing of the line for pump inspection and
maintenance.
2.
Keep suction pipe free from air pockets.
3.
Piping should be level or slope gradually downward
from the source of supply
Pump must never be throttled on suction side.
4.
Suction strainers, when used, must have a net “free
area” of at least three times the suction pipe area.
4.
No portion of the piping should extend below pump
suction flnge.
5.
Separate suction lines are recommended when more
than one pump is operating from the same source of
supply.
5.
The size of entrance from supply should be one or two
sizes larger than the suction pipe.
6.
The suction pipe must be adequately submerged below
the liquid surface to prevent vortices and air
entrainment at the supply.
24
3298 Family Rev. 5/08
DISCHARGE PIPING
INCORRECT PIPING
1.
Isolation and check valves should be installed in
discharge line. Locate the check valve between
isolation valve and pump, this will permit inspection of
the check valve. The isolation valve is required for
priming, regulation of flow, and for inspection and
maintenance of pump. The check valve prevents pump
or seal damage due to reverse flow through the pump
when the driver is turned off.
2.
Increasers, if used, should be placed between pump
and check valves.
3.
Cushioning devices should be used to protect the
pump from surges and water hammer, if quick-closing
valves are installed in system.

CONNECT CONDITION
MONITORING DEVICES
If unit is equipped with power monitoring systems, this
must be connected.
PRIMING PUMP
Never start pump until properly primed (pump casing and
suction piping are full of liquid). Components such as
internal sleeve bearings depend on liquid for lubrication
and will quickly fail if run dry.
Your particular system conditions will dictate method used
to prime pump.

MAINTENANCE OF BEARINGS—FRAME MOUNTED
STANDARD CLOSE COUPLED PUMP
Many 3298s, SP 3298s, and V 3298s are close coupled
mounted as standard. Close coupled pumps do not have
bearings which require lubrication.
this section on bearing lubrication,
! Throughout
different pumpage temperatures are listed. If the
equipment is ATEX certified and the listed
temperature exceeds the applicable value shown in
Table 1 under Safety, then that temperature is not
valid. When this situation occurs, please consult
with your ITT/Goulds representative.
OIL LUBRICATED BEARINGS
!
▲
WARNING
Pumps are shipped without oil. Oil lubricated bearings
must be lubricated at the job site.
Remove fill plug (113A) and add oil until level is at the
center of the sight glass (319). Replace fill plug (Fig. 32)
(See Table 6).
Fig. 32
OIL LUBRICATED BEARINGS
Frame mounted 3298s and SP 3298s do have bearings
which require lubrication. Oil level is measured through
the sight glass. Oil level must not fall below center of site
glass. An increase in level may be noted after start up due
to oil circulation within the bearing frame. Change oil after
200 hours for new bearings, thereafter, every 4000
operating hours or 6 months, whichever period is shorter.

Table 7A
Failure Symptoms Due to Dry Run Operation
Poor lubrication or dry run operation of 3298 liquid lubricated bearing surfaces results in a significant increase of heat generation. The
lack of cooling flow through the pump also causes significant temperature increase of the bearings. This temperature increase causes
damage to the surrounding parts as described and shown in Fig. 33: (Numbers in Fig. 33 correspond to numbers described below).
1.
The plastic surrounding the outboard thrust bearing may be melted.
2.
The plastic surrounding the carbon or silicon carbide impeller radial bearings may be melted.
3.
The plastic surrounding the inboard thrust bearings may be melted.
4.
If the impeller seizes on the shaft due to excessive heat, the shaft may spin in the shaft spider, wearing the inside diameter of
the shaft spider.
REMEDY
A.
Install dry run protection device like a power monitor (refer to appendix for more information on power monitors)
B.
Modify process system or controls to eliminate dry run operation.
C.
Change bearing material to DryGuard™ coated silicon carbide if silicon carbide bearings were initially installed in the pump.

RETURN OF MATERIALS
If it is necessary to return the pump to a Goulds factory or
repair facility for service, certain procedures must be
followed.
Do not return any parts without authorization from the
warranty engineer, a warranty claim number, and the
preprinted shipping label supplied by Goulds. In rare
instances because of the pumpage, ITT Goulds Pumps
Warranty Services may, at their option, decide not to have
the parts returned.
The parts being returned must be decontaminated prior to
shipment. The decontamination must be verified in
writing. The correct Material Safety Data Sheet (MSDS)
must accompany the parts along with decontamination
"sign off." This information is stated within the ITT
Goulds Pumps "decontamination procedure." The
Warranty Service engineer will send a copy of this
procedure to the customer. Please remember that
inspection of the parts cannot be started until we receive
the proper documentation. This is a safety and legal issue
and consequently strict adherence to procedure is
mandatory — there will be no exceptions.
Before shipping, check with your carrier for special
procedures that may be required when shipping highly
magnetic materials.
All pumps must be decontaminated prior to return. Refer
to Preparation for Disassembly and Decontamination
Procedure.

COUPLING GUARD INSTALLATION Frame Mounted Only
!
The coupling guard used in an ATEX classified
environment must be constructed from a nonsparking material.
B▲
!
WARNING
Before assembly or disassembly of the coupling guard is
performed, the motor must be de- energized, the motor
controller/starter put in a locked-out position, and a
caution tag placed at the starter indicating the disconnect.
Replace coupling guard before resuming normal
operation of the pump. Goulds Pumps assumes no
liability for avoiding this practice.
XLT-X Align the end plate (pump end) to the pump
bearing housing so that the large slots on the end
plate clear the bearing housing tap bolts and the small
slots are aligned to the impeller adjusting bolts.
Attach the end plate to the bearing housing using the
jam nuts on the impeller adjusting bolts as shown in
Fig. II-3.
After the end plate is attached to the bearing housing,
the impeller clearance must be checked and reset as
explained in the Preventive Maintenance section.
NOTE: Coupling adjustments should be completed
before proceeding with coupling guard assembly.
Fig. II-2
8
Fig. II-1
Simplicity of design allows complete assembly of the
coupling guard, including the end plate (pump end), in
about fifteen minutes. If the end plate is already in place,
assembly can be accomplished in about five minutes.
Assembly:
NOTE: If end plate (pump end) is already installed,
make any necessary coupling adjustments and then
proceed to Step 2.
Fig. II-3
1. STX, MTX, LTX - Align end plate (pump end) to
the bearing frame. (No impeller adjustment
required.)
3298 Family Rev. 5/08
131
2. Spread bottom of coupling guard half (pump end)
slightly and place over pump end plate as shown in
Fig. II-4. The annular groove in the guard half is
located around the end plate (Fig. II-5).
Fig. II-7
4. Spread bottom of coupling guard half (driver end)
slightly and place over coupling guard half (pump
end) so that annular groove in coupling guard half
(driver end) faces the motor as shown in Fig. II-8.
Fig. II-4
Fig. II-5
3. After the coupling guard half (pump end) is located
around the end plate, secure it with a bolt, nut and
two washers through the round hole at the front end
of the guard half as shown in Fig. II-6. Tighten
securely (Fig. II-7).
Fig. II-8
Fig. II-6
132
3298 Family Rev. 5/08
5. Place end plate (driver end) over motor shaft as
shown in Fig. II-9. Locate the end plate in the
annular groove at the rear of the coupling guard half
(driver end) and secure with a bolt, nut, and two
washers through the round hole at the rear of the
guard half. Finger tighten only.
Fig. II-10
Disassembly
The coupling guard must be removed for certain
maintenance and adjustments to the pump, such as
adjustment of the coupling, impeller clearance
adjustment, etc. The coupling guard should be replaced
after maintenance is completed.
Fig. II-9
6. Adjust length of coupling guard to completely cover
shafts and coupling as shown in Fig. II-10 by sliding
coupling guard half (driver end) towards motor.
After adjusting guard length, secure with bolt, nut
and two washers through the slotted holes at the
center of the guard and tighten. Check all nuts on the
guard assembly for tightness.

!
WARNING
Before assembly or disassembly of the coupling guard is
performed, the motor must be de- energized, the motor
controller/starter put in a locked-out position, and a
caution tag placed at the starter indicating the disconnect.
Replace coupling guard before resuming normal
operation of the pump. Goulds Pumps assumes no
liability for avoiding this practice.
DO NOT resume normal pump operation with the
coupling guard removed.
NOTE: Refer to illustrations for assembly in reverse
order.
1. Remove nut, bolt, and washers from center slotted
hole in the coupling guard. Slide motor end coupling

POWER MONITORS
CONDENSED POWER MONITOR USER GUIDE
ITT Goulds Pumps offers various power monitoring
devices which have been designed to protect pumps from
dry-running, running against a closed discharge valve,
and running outside of the recommended operating region
for specific pump sizes, speeds, and impeller diameters.
Power monitors were designed to detect power relative to
load which is a linear function as opposed to measuring
amperage relative to load which is a parabolic function.
The linear characteristic of measuring power vs. load
enhances sensitivity at low power conditions where
increments in power are critical. See Fig. IV-1 for
comparison of power measurements vs. amperage
measurements. Quite simply, a properly adjusted and
installed power monitor is an insurance policy for
securing extended pump life.
The following summarized concepts will assist in
effectively selecting and properly calibrating power
monitors used to protect pumps.
1. Read your power monitor installation instructions
and wiring diagram before attempting to calibrate the
unit.
2. Understand your pump’s recommended operating
envelope as provided by ITT Goulds Pumps.
4. Understand the full range of your operating duty,
including power requirements at the rated minimum
and maximum flow conditions.
5. If only small fluctuations occur between the rated
point and trip points (less than 15% of the total motor
horsepower available), then the Integra Motor
Minder should not be used. In this case, use either
the Emotron or Load Controls unit as they can
detect to approximately 1% changes in horsepower.
6. Understand the relationship and limitations of item
numbers 2, 3, and 4 as an integrated functional
system.
7. Identify potential failures that would most likely be
characteristic of your specific process and the pump
type selected.
8. Understand the power scope and torque scope of the
selected electric motor.
9. A complete analysis of the above concepts will
define a safe operating range for your specific
system.
10. When feasible, further define your operating range to
run as close to BEP (best efficiency point) as
practical.
11. Select single trip unit or dual trip unit as practical for
your specific system.
12. Set low power trip point at the power draw required
when operating at the manufacturer’s recommended
minimum flow or higher, yet less than the normal
operating point.
13. Set the high trip point at the power draw required
when operating at the manufacturer’s recommended
maximum flow or lower, or at flow rate that will
prevent cavitation.
Fig. IV-1
3. Understand your systems requirements and
limitations.
3298 Family Rev. 5/08
14. When using dual trip power monitors, select high and
low trip points designed to protect your specific
system within the recommended pump operating
region defined by ITT Goulds Pumps. This method
will create boundaries for a safe pump operating
envelope.
139
8
POWER MONITORS, (cont’d)
15. Set nuisance trip feature for each power trip. The
nuisance trip device should be set at an appropriate
interval that will allow the system to experience
momentary fluctuations in power draw. However,
the nuisance trip device should also be set at an
appropriate time frame that will prevent the pump
from experiencing excessive heat or dangerous
operating conditions.
16. Set the delay timer for start-up conditions that will
appropriately allow the system to come to normal
operating power within a time frame that will
maximize protection of your pump.
17. For variable speed operation, consult ITT Goulds
Pumps or the power monitor manufacturer for
appropriate auxiliary devices designed for operating
at multiple speeds or fluctuating frequencies.
18. Select electrical enclosure that is suitable for the
operating environment or install the unit in an
appropriate electrical panel.
19. Do not activate the power monitor’s manual override
until a thorough examination of the source of the
problem is defined and corrected.
20. Investigate and select power monitor features that are
most suitable for your particular application and plant
safety.
Power monitors can be strategically calibrated to protect
your pump from any of the following conditions by
appropriately determining the power draw at any of these
individual conditions:
·
·
·
·
Dry Running
Closed Discharge Valve
·
·
·
·
·
·
·
·
·
·
·
Plugged Suction
Cavitation
Air Lock
Decoupled Magnets
Solidified, Plugged, or Frozen Discharge Line
Fluctuating Viscosities, Precipitation, or
Coagulation
Broken or Damaged Shaft
Broken or Damaged Coupling
Jammed Impeller
Bad Bearings
Rapid Cycling
The power draw at each of these conditions can be
simulated in a plant test or estimated through calculations
or interpolations from the pump performance curve. By
defining these dangerous power fluctuations, appropriate
calibration of the power monitoring unit will prevent
avoidable pump failures. See Fig. IV-2 for a typical
power evaluation recorded from a common centrifugal
pump electric motor.
Contact ITT Goulds Pumps Application Engineering staff
or regional distributor for assistance and power analysis
for your specific system.
For further details and evaluation of power monitoring
units, a comprehensive power monitor user guide is
available from ITT Goulds Pumps distribution network.

Polyshield® ANSI Combo
Installation, Operation, and Maintenance Instructions
SAFETY CONSIDERATIONS
APPLICATION
Several important general precautions are listed below:
The polymer concrete material used in the manufacture of
the Polyshield® ANSI Combo has been formulated for
application in a wide range of corrosive fluid handling
services. The material is not, however, universally
corrosion resistant. A comprehensive corrosion guide is
available. (Refer to Accessories Section of the Electronic
Pricebook.) It is strongly recommended that this bulletin
be reviewed prior to specifying or installing a Polyshield®
Product.
1. Do not remove the Polyshield® ANSI Combo from its
shipping pallet until you are ready to hoist it onto its
location.
2. Do not subject the Polyshield® ANSI or Custom
Combo to rough handling or unnecessary mechanical
shock.
3. Do not attempt to lift the Polyshield® ANSI Combo
by any means other than that which is prescribed in
these procedures.
4. Do not use hammer blows or other impact loading to
adjust the positioning of the Polyshield® ANSI
Combo. Do not pry against the Polyshield® mounting
block when moving the motor during shaft alignment.
5. Do not attempt to transport, handle, or install a
Polyshield® ANSI Combo when ambient temperature
is below -50° F (-45° C).
6. Do not operate a pump installed on a Polyshield® ANSI
Combo at process fluid temperatures in excess of 300° F
(150° C) with polymer mounting pads and 500° F with
alloy mounting pads unless prior approval from ITT
Industries - Goulds Pumps is obtained in writing.

environment is limited by Table 1 in the Safety
Section.
NOTE: Always coordinate installation activity with
operations personnel, and follow all plant safety
requirements and applicable safety and health laws,
directives and regulations.
OVERVIEW
$
STORAGE
This section addresses the storage procedures for the
Polyshield® ANSI Combo only. When storing
Polyshield® ANSI Combos and pump assemblies, it is
important that the proper storage procedures for the pump
be observed as well. Refer to the Installation, Operation
and Maintenance Instructions (IOM) for the particular
Goulds pump that is mounted on your Polyshield®
product.
Polyshield® normal packaging is designed to protect the
Polyshield® ANSI Combo during shipment and handling
from the time it is manufactured at the factory to
installation at the end user’s job site. If the Polyshield®
Combo is to be stored for a period of time prior to
installation, it is recommended that the following
procedures be followed:
a.
CAUTION
Observance of proper handling procedures during
installation is extremely important to prevent damage
to the Polyshield® ANSI Combo. While polymer
concrete possesses inherent high strength, subjecting it
to impact or bending loads through rough handling or
improper lifting or mounting may result in irreparable
damage to the Polyshield® ANSI Combo as well as
damage to the mounted equipment or injury to
personnel.
3298 Family Rev. 5/08
The Polyshield® ANSI Combo is also suitable for
application in a wide range of fluid process temperatures,
specifically, -50° F to 300° F (-45° C to 150° C).
Depending on the configuration of the pump that is to be
mounted on the Polyshield®, fluid process temperature in
excess of 300° F (150° C) may be permissible. Contact
your ITT Industries - Goulds Pumps representative for
assistance in determining acceptability of a specific
application.
Leave the Polyshield® ANSI Combo strapped to its
wooden shipping pallet.
b. Place the pallet on a solid, dry, level surface in a
location where the ANSI Combo cannot be struck by
passing fork trucks, falling objects, etc. Make sure
the pallet does not rock.
c.
Do not stack heavy objects on top of the Polyshield ®
ANSI Combo.
d. If the Polyshield® ANSI Combo is to be stored in an
143
8
outdoor location, cover the Polyshield® completely
with a tarpaulin or dark plastic sheeting to prevent
UV degradation of the surface.
NOTE: UV degradation (bleaching) of the polymer
concrete is the normal result of exposure to sunlight.
This phenomenon is purely a visible change in the
color of the material, which in no way compromises
the performance or corrosion resistance
characteristics of the Polyshield®.
!
▲
WARNING
Do not attempt to stand a Polyshield® on its
end to make more efficient use of storage space.
Neither the Polyshield® Combo nor the strapping that
holds the Polyshield® Combo to its wooden pallet
have been designed for vertical storage. Severe
personal injury or death, as well as irreparable
damage to the Polyshield® Combo may result if the
Combo tips over.

Lifting Polyshield Combo Units and Polyshield
Combo / Pump Assemblies
$
®
CAUTION
®
Polyshield units should be transported via
fork truck to the area of their intended installation on
the wooden pallets on which they were shipped. Never
transport a Polyshield® unit over a long distance or
over rough terrain while suspended from slings.
Only trained personnel should do lifting. Pumps and
motors often have integral lifting eyes or eye bolts.
These are intended for use in lifting the individual
pieces of equipment. Do not use these features to lift a
Polyshield® Combo / pump assembly.
Lifting
The following procedures are recommended for lifting
Polyshield® ANSI Combo units:
Polyshield® with no mounted equipment:
!
▲
WARNING
Do not install eyebolts in the Polyshield® thread
inserts for the purpose of lifting the base. This
practice imposes lateral loads on the inserts — which
they were not designed to withstand.
Remove the metal shipping straps that hold the
Polyshield® unit to the wooden pallet. Slip slings under
each end of the Polyshield® unit as a harness (Fig. VI-1).
144
Fig. V-1
Lift the Polyshield® unit a few inches off the pallet and
verify that it hangs reasonably level and that the slings are
not prone to slipping out of position.
!
▲
WARNING
Keep hands and feet out from under the Polyshield ®
unit during these steps. If slings slip and the unit tips
over, severe personal injury or death may result, as
well as irreparable damage to the Polyshield®
Combo.
If the sling appears to be unstable, set the Polyshield® unit
back on the pallet and reposition the slings.
After satisfactory slinging has been achieved, the
Polyshield® unit may be hoisted onto its foundation.
Take care not to bump the unit against fixed objects or
induce any unnecessary shock loads. Lower the unit
slowly over the foundation using care to center the unit
over the rebar cage. Place shim packs or wedges under the
Polyshield® unit at a minimum of eight total or (four [4]
locations on each side) to allow for the removal of the
slings. Twelve (12) total shim locations or (six [6] shim
locations each side are required for Polyshield® units
exceeding six feet in length.
POLYSHIELD® WITH INSTALLED
EQUIPMENT:
Pump and motor installed:
Remove the metal shipping straps that hold the
Polyshield® unit to the wooden pallet. Slip slings under
each end of the Polyshield® unit. This procedure is
recommended up to the MTX or LTX pump units. All
motors up to a 364T NEMA frame may be installed while
mounted. Motor frame sizes 365T or larger should be
removed during locating and installation of the
Polyshield® ANSI Combo units. Check to see that the
pump suction nozzle does not interfere with the lifting
sling. If the pump creates interference, it should be
removed. Lift the Polyshield® ANSI Combo a few inches
off the pallet and verify that it hangs reasonably level and
that the slings are not prone to slipping out of position.
3298 Family Rev. 5/08

INSTALLATION
General Description of the Polyshield® ANSI Combo
The Polyshield® ANSI Combo is a solid, polymer
concrete foundation and baseplate shell that is
manufactured in versions that conform to accommodate
ASME/ANSI B73.1 pumps.
Polyshield® ANSI Combo units are manufactured in five
primary sizes with integral catch basins and removable
motor mounting blocks.
Metallic thread inserts are provided in the mounting
surface for the particular combination of pump and motor
that the Combo is intended. The metallic thread inserts on
the pump end are available in 316SS (18.8 CrNi stainless
steel), Alloy 20 (A744, CN-7M) and Hastelloy C 276
(A494, CW-6M). Multiple motor insert patterns are also
available to accommodate more than one NEMA frame
size. The standard thread insert material for the motor end
is 316SS (18.8 CrNi stainless steel).
Optional alloy pads are available instead of metallic
inserts for requirements that call for 0.002”/ft. and or
process temperatures between 301° F and 500° F.
Polyadjust Motor Block Adjuster System
The Polyshield® ANSI Combo utilizes as standard the
unique Polyshield® Polyadjust motor mounting system
(Fig. VI-2). This system is comprised of a one-piece
polymer concrete motor mounting block having surface
flatness and parallelism equivalent to machine steel
blocks. The Polyadjust motor mounting block system
incorporates the Polyloc Transverse Jack Bolt system.
The Polyloc system provides transverse motor
adjustment. The side-mounted adjusters allow for shaft
alignment to critical tolerances with minimal disturbance
of indicators. The adjusters make contact with a solid
motor mounting block not the foot of the motor.
3298 Family Rev. 5/08

Polyshield® ANSI and Custom Combos Installation
Procedures (NEW CONSTRUCTION)
1. Remove laitance and form grease and oil from area
where the Polyshield® ANSI Combo will be located
using mechanical means, abrasive blasting, or water
blasting. Remove any loose debris including fins,
aggregate, or any protruding objects around the
perimeter of the area where the Polyshield ANSI
Combo will rest.
2. Measure the outside dimensions of the Polyshield®
ANSI Combo and subtract 8” from both the width
and length to determine the rebar maximum
dimension, thus providing clearance from the side of
the walls of the ANSI Combo.
3. Drill holes in the existing slab a minimum of four
inches deep for doweling in the vertical rebar rods
allowing a minimum of one inch clearance from the
top of the interior of the Polyshield® ANSI Combo.
Space the rebar rods of 12” centers. Remove dust
and debris from dowel holes and fill with epoxy
adhesive for anchoring the rebar.
4. Allow the epoxy adhesive to cure, and then install
horizontal rebar rods, tying in place with wire.
5. Place the Polyshield® ANSI Combo over the rebar
cage, making adjustments for proper elevation,
orientation relative to piping centerlines. A qualified
millwright should field verify proper position of the
pump mounting pads relative to the centerline of the
suction piping. Appropriate shims may be placed
along the bottom edge of the Polyshield® ANSI
Combo to aid in leveling. Place shim packs or
wedges under the Polyshield® unit at a minimum of
eight total (or four [4] locations on each side) to
allow for the removal of the slings and metal lifting
straps from each end. A minimum of twelve (12)
total shim locations (or six [6] shim locations each
side) are recommended for Polyshield® units
exceeding seven feet in length.

6. Check and verify the dimensions again before the
grouting procedure begins.
7. A low slump standard concrete mix is suitable for
filling the Polyshield® ANSI Combo in new
construction.
8. Seal around the outside bottom perimeter of the
Polyshield® ANSI Combo with a fast setting
hydraulic cement. Two brand name hydraulic
cements are: Water Plug Hydraulic Cement and
Dam-It Non Shrink Hydraulic Cement.
9. Pour the concrete mixture through the grout fill port
on the top of the Polyshield® ANSI Combo using a
concrete vibrator to ensure proper flow of the
concrete. Do not over vibrate as excessive vibrating
leads to larger aggregate settling which will result in
a weak mix.
10. Pour the concrete to the bottom edge of the grout fill
port.
11. Remove any loose debris from around edges of the
grout fill port.
12. Seal grout fill port with grout port plug and
Polyshield® Seal Kit provided.
13. Install pump, motor, and attach lines.
