1 Introduction and Safety
1.1 Important Safety Notice
To: Our Valued Customers:
User safety is a major focus in the design of our products. Following the precautions outlined in this man-
ual will minimize your risk of injury.
ITT Goulds pumps will provide safe, trouble-free service when properly installed, maintained, and operat-
ed.
Safe installation, operation, and maintenance of ITT Goulds Pumps equipment are an essential end user
responsibility. This Pump Safety Manual identifies specific safety risks that must be considered at all
times during product life. Understanding and adhering to these safety warnings is mandatory to ensure
personnel, property, and/or the environment will not be harmed. Adherence to these warnings alone,
however, is not sufficient — it is anticipated that the end user will also comply with industry and corporate
safety standards. Identifying and eliminating unsafe installation, operating and maintenance practices is
the responsibility of all individuals involved in the installation, operation, and maintenance of industrial
equipment.
Please take the time to review and understand the safe installation, operation, and maintenance guide-
lines outlined in this Pump Safety Manual and the Instruction, Operation, and Maintenance (IOM) man-
ual. Current manuals are available at https://www.gouldspumps.com/en-US/Tools-and-Resources/Litera-
ture/ or by contacting your nearest Goulds Pumps sales representative.
These manuals must be read and understood before installation and start-up.
For additional information, contact your nearest Goulds Pumps sales representative or visit our Web site
at https://www.gouldspumps.com
1.2 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 con-
tents of the pump and eliminate the possibility of exposure, particularly if hazardous and/or tox-
ic. Potential hazards include, but are not limited to, high temperature, flammable, acidic, caus-
tic, explosive, and other risks.
1 Introduction and Safety
Model 3299 Installation Operation Maintenance 3

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 for-
bidden. 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 http://www.gouldspumps.com/literature.

equipment only at specifically identified lifting points or as instructed in the current IOM.
Current manuals are available at www.gouldspumps.com/literature_ioms.html or from
your local ITT Goulds Pumps sales representative. Note: Lifting devices (eyebolts,
slings, spreaders, etc.) must be rated, selected, and used for the entire load being lifted.
1.4 General precautions
Model 3299 Installation Operation Maintenance 5

WARNING Alignment:
Shaft alignment procedures must be followed to prevent catastrophic failure of drive
components or unintended contact of rotating parts. Follow coupling manufacturer's
coupling installation and operation procedures.
WARNING Before beginning any alignment procedure, make sure driver power is locked out. Fail-
ure to lock out driver power will result in serious physical injury.
CAUTION Piping:
Never draw piping into place by forcing at the flanged connections of the pump. This
may impose dangerous strains on the unit and cause misalignment between pump and
driver. Pipe strain will adversely effect the operation of the pump resulting in physical in-
jury and damage to the equipment.
WARNING Flanged Connections:
Use only fasteners of the proper size and material.
WARNING Replace all corroded fasteners.
WARNING Ensure all fasteners are properly tightened and there are no missing fasteners.
WARNING Startup and Operation:
When installing in a potentially explosive environment, please ensure that the motor is
properly certified.
WARNING Operating pump in reverse rotation may result in contact of metal parts, heat generation,
and breach of containment.
WARNING Lock out driver power to prevent accidental start-up and physical injury.
WARNING The impeller clearance setting procedure must be followed. Improperly setting the clear-
ance or not following any of the proper procedures can result in sparks, unexpected
heat generation and equipment damage.
WARNING If using a cartridge mechanical seal, the centering clips must be installed and set screws
loosened prior to setting impeller clearance. Failure to do so could result in sparks, heat
generation, and mechanical seal damage.
WARNING The coupling used in an ATEX classified environment must be properly certified and
must be constructed from a non-sparking material.
WARNING Never operate a pump without coupling guard properly installed. Personal injury will oc-
cur if pump is run without coupling guard.
WARNING Make sure to properly lubricate the bearings. Failure to do so may result in excess heat
generation, sparks, and / or premature failure.
CAUTION The mechanical seal used in an ATEX classified environment must be properly certified.
Prior to start up, ensure all points of potential leakage of process fluid to the work envi-
ronment are closed.
1.4 General precautions
6 Model 3299 Installation Operation Maintenance

CAUTION Never operate the pump without liquid supplied to mechanical seal. Running a mechani-
cal seal dry, even for a few seconds, can cause seal damage and must be avoided.
Physical injury can occur if mechanical seal fails.
WARNING Never attempt to replace packing until the driver is properly locked out and the coupling
spacer is removed.
WARNING Dynamic seals are not allowed in an ATEX classified environment.
WARNING DO NOT operate pump below minimum rated flows or with suction and/or discharge
valve closed. These conditions may create an explosive hazard due to vaporization of
pumpage and can quickly lead to pump failure and physical injury
WARNING Ensure pump is isolated from system and pressure is relieved before disassembling
pump, removing plugs, opening vent or drain valves, or disconnecting piping.
WARNING Shutdown, Disassembly, and Reassembly:
Pump components can be heavy. Proper methods of lifting must be employed to avoid
physical injury and/or equipment damage. Steel toed shoes must be worn at all times.
WARNING The pump may handle hazardous and/or toxic fluids. Observe proper decontamination
procedures. Proper personal protective equipment should be worn. Precautions must be
taken to prevent physical injury. Pumpage must be handled and disposed of in conform-
ance with applicable environmental regulations.
WARNING Operator must be aware of pumpage and safety precautions to prevent physical injury.
WARNING Lock out driver power to prevent accidental startup and physical injury.
CAUTION Allow all system and pump components to cool before handling them to prevent physi-
cal injury.
CAUTION If pump is a Model NM3171, NM3196, 3198, 3298, V3298, SP3298, 4150, 4550, or
3107, there may be a risk of static electric discharge from plastic parts that are not prop-
erly grounded. If pumped fluid is non-conductive, pump should be drained and flushed
with a conductive fluid under conditions that will not allow for a spark to be released to
the atmosphere.
WARNING Never apply heat to remove an impeller. The use of heat may cause an explosion due to
trapped fluid, resulting in severe physical injury and property damage.
CAUTION Wear heavy work gloves when handling impellers as sharp edges may cause physical
injury.
CAUTION Wear insulated gloves when using a bearing heater. Bearings will get hot and can cause
physical injury.
1.5 ATEX Considerations and Intended Use
Special care must be taken in potentially explosive environments to ensure that the equipment is proper-
ly maintained. This includes but is not limited to:
Description of ATEX
The ATEX directives are a specification enforced in Europe for electrical and non-electrical equipment
installed in Europe. ATEX deals with the control of potentially explosive atmospheres and the standards
1.5 ATEX Considerations and Intended Use
Model 3299 Installation Operation Maintenance 7

of equipment and protective systems used within these atmospheres. The relevance of the ATEX re-
quirements is not limited to Europe. You can apply these guidelines to equipment installed in any poten-
tially explosive atmosphere.
Guidelines for compliance
Compliance is fulfilled only when you operate the unit within its intended use. Do not change the condi-
tions of the service without the approval of an ITT representative. When you install or maintain explosion
proof products, always comply with the directive and applicable standards (for example, IEC/EN
60079-14).
1. Monitoring the and liquid end temperature.
2. Maintaining proper bearing lubrication.
3. Ensuring that the pump is operated in the intended hydraulic range.
The ATEX conformance is only applicable when the pump unit is operated within its intended use. Oper-
ating, installing or maintaining the pump unit in any way that is not covered in the Instruction, Operation,
and Maintenance manual (IOM) can cause serious personal injury or damage to the equipment. This in-
cludes any modification to the equipment or use of parts not provided by ITT Goulds Pumps. If there is
any question regarding the intended use of the equipment, please contact an ITT Goulds representative
before proceeding.

2 Introduction
2.1 Purpose of manual
This manual is furnished to acquaint you with the easiest and most practical way to install, operate, and
maintain this pump. Read it completely before doing any work on your unit and keep it handy for future
reference.
Equipment cannot operate well without proper care. To keep the unit at top efficiency, follow the recom-
mended installation and servicing procedures out lined in this manual. Goulds Pumps Sales and Service
Parts Central is available to expertly guide the installation of the pump for maximum operating life and
minimum downtime.
Goulds Model 3299 Plastic Lined Magnetic Drive pumps are frame mounted, volute type centrifugal
pumps which are separately coupled to a driver such as an induction motor. Goulds Model 3299 Plastic
Lined Magnetic Drive pumps are also available close coupled to a C-face motor; there is no separate
pump bearing frame.
The magnet drive is a coaxial synchronous drive which utilizes permanent (passive) magnets on both the
inner and outer carriers. The attraction between North and South pole pairs allows 100% speed transfer
from the motor to the pump impeller. The drives have constant maximum torque ratings irrespective of
speed.
The 3299 is available in five sizes and various liner materials. Throughout these instructions Group I and
II sizes are referred to. These can be easily identified as follows:
Group Pump size
I l x l.5-6, 2x3-6, l x l.5-8
II 1.5 x 3-8, l x 2-10

NOTICE:
There are five (5) basic drive frames available on the 3299. Drive frame designations are: A, B,
C, D, E. Refer to Appendix A Engineering Information for torque ratings of these drives. Drive
capability varies inversely with pumping temperature. However, the proper drive selection de-
pends on many other considerations such as speed, magnet material, liquid viscosity, specific
gravity, impeller diameter, bearing loads, etc. Always contact your nearest Goulds Pumps rep-
resentative when changing service conditions.
WARNING:
Do not run unit dry; severe pump damage can occur. Failure to follow these instructions could
result in property damage, severe personal injury, or death.
WARNING:
This unit contains high power magnets. Persons wearing pacemakers must no, be allowed
near this equipment. Close location of watches, credit cards, computer tapes, disks, or memory
devices must be avoided to prevent damage. Failure to follow these instructions could result in
property damage, severe personal injury, or death.
WARNING:
•
Follow the Horizontal Pump Lifting Instruction Booklet (52-328-427) attached to the pump.
Unit weights are given on page 33. Failure to follow these instructions could result in
property damage, severe personal injury, or death.

Model 3299 Installation Operation Maintenance 11

• Read all warning and caution decals on the pump. Do not operate without all guards in
place.
• Never use motor lifting lugs or pump drive frame lifting eye to lift the entire pump-driver-
baseplate unit.
• Disconnect and lock out power before servicing.
When field hydro-testing pump or system, do not exceed maximum design pressure given on pump
nameplate. Vent all air from pump and piping.
CAUTION:
For frame mounted units, check rotation of driver with coupling disconnected. On close coupled
units jog the pump and motor momentarily, about a half second, so that the motor rotation can
be confirmed by observing the motor fan direction. The proper pump rotation is clockwise as
viewed from the motor fan end. Failure to follow these instructions could result in severe per-
sonal injury or property damage.
WARNING:
Do not operate at or near zero flow (closed shutoff valve). Explosion could result due to large
temperature rise in the fluid being pumped. Failure to follow these instructions could result in
property damage, severe personal injury, or death.
WARNING:
If pump is to be used on process fluids above 120°F pump surface temperatures could be hot
enough to cause burns. We recommend pump casing surfaces be insulated. Failure to follow
these instructions could result in severe personal injury or death.
CAUTION:
When shipping bare magnet assemblies, especially by air, special precautions may be neces-
sary. Usually the shipment of an assembled pump is not a problem. It is advisable to consult
with the freight company.

Model 3299 Installation Operation Maintenance 13

5 Installation
5.1 Receiving pump
Check pumps for shortages and damage immediately upon arrival. (An absolute must!) Prompt reporting
to the carrier's agent, with notations made on the freight bill, will expedite satisfactory adjustment by the
carrier.
Pumps and drivers are normally shipped from the factory mounted on a baseplate. Couplings may either
be completely assembled or have the coupling hubs mounted on the shafts and the connecting members
removed. When the connecting members are removed, they will be packaged in a separate container
and shipped with the pump or attached to the baseplate.
Shafts are in alignment when the unit is shipped; however, due to shipping, the pumps may arrive mis-
aligned and, therefore, final alignment must be established during installation. Goulds Pumps has deter-
mined that proper and correct alignment can only be made by accepted erection practices. Refer to the
following paragraphs on 5.4 Foundation on page 15, 5.5 Setting baseplate on page 16, 5.6 Alignment
procedure on page 19 and 5.7 Doweling on page 20. All pumps have been factory tested with water. If
no special requirements have been specified, prior to shipping, a small quantity of water may remain in-
side the pump. This should be noted due to possible reactions with the pumped liquid or flushing liquid.
5.2 STORAGE
1. Temporary:
Temporary storage is considered one month or less. If the pump is not to be installed and operat-
ed soon after arrival, store it in a clean, dry place having slow, moderate changes in ambient tem-
perature. Rotate the shaft periodically to coat the bearings with lubricant and to retard oxidation,
corrosion, and to reduce the possibility of false brinelling of the bearings.
For complete details on temporary storage, consult Bulletin 52-130-372 in your submittal pack-
age or request a copy from your nearest Goulds Pumps Representative.
2. Long Term:
Plastics are subject to cold flow, i.e., plastic parts may deform even when they are not in use. It is
recommended to consult with Goulds Pumps if the pumps have been stored for a long period.
Storage longer than one month is considered long term storage. Refer to Bulletin 52-130-373 in
your submittal package or request a copy from your nearest Goulds Pumps Representative.
5.3 Location
The pump should be installed as near the suction supply as possible, with the shortest and most direct
suction pipe practical. The total dynamic suction lift (static lift plus friction losses in suction line) should
not exceed the limits for which the pump was sold.
5 Installation
14 Model 3299 Installation Operation Maintenance

Figure 2: Foundation
The pump must be primed before starting. Whenever possible, the pump should be located below the
fluid level to facilitate priming and assure a steady flow of liquid. This condition provides a positive suc-
tion head on the pump. It is also possible to prime the pump by pressurizing the suction vessel.
When installing the pump, consider its location in relation to the system to assure that sufficient Net Posi-
tive Suction Head (NPSH) at pump suction is provided. Available NPSH must always exceed the re-
quired NPSH of the pump.
The pump should be installed with sufficient accessibility for inspection and maintenance. A clear space
with ample head room should be allowed for the use of an overhead crane or hoist sufficiently strong to
lift the unit.
NOTICE:
Allow sufficient space to be able to dismantle pump without disturbing the pump inlet and dis-
charge piping.
The pump should be located in a dry place above the floor level whenever possible. Take care to prevent
the pump from freezing during cold weather when not in operation. Should the possibility of freezing exist
during shut-down period, the pump should be completely drained, and all passages and pockets where
liquid might collect should be blown out with compressed air.
Make sure there is a suitable power source available for the pump drive. If motor driven, electrical char-
acteristics should be identical to those shown on motor data plate.
5.4 Foundation
The foundation must be substantial enough to absorb vibration. (Hydraulic Institute Standards recom-
mend the foundation weight be at least five (5) times the weight of the pump unit) It must form a perma-
nent and rigid support for the baseplate. This is important in maintaining the alignment of a flexibly cou-
pled unit.
Foundation bolts 0.25" smaller in diameter than the clearance holes in the baseplate should be embed-
ded in the concrete to a depth of eight (8) times the diameter of the bolt and locked with either a hook
around a reinforcing bar or alternatively, a nut and washer at the bottom. The bolts should have a sleeve
around them at least six (6) times the bolt diameter long and at least two (2) bolt sizes larger in I.D. If a
nut and washer are used for locking, the washer should have an O.D. two (2) sizes larger than the
sleeve.
5.4 Foundation
Model 3299 Installation Operation Maintenance 15

The foundation should be poured within 0.75 - 1.5" of the finished height. (See Figure 2: Foundation on
page 15). Freshly poured foundations should be allowed to cure for several days before the unit is set in
place and grouted.
5.5 Setting baseplate
Pump units are checked at the factory for align ability to required tolerances. Due to flexibility of an
ungrouted base and handling in shipment, it should not be assumed that the unit is in alignment when it
is placed on the rough foundation. If these directions are followed, the required alignment should be
readily achieved.
Initial or rough alignment must be done prior to grouting of baseplate. Rough alignment is designated
as .020" TIR parallel alignment and .009" TIR per inch of radius angular alignment (Refer to 5.6 Align-
ment procedure on page 19). Use blocks at anchor bolts and midway between to position bottom of
base at finished height (See Figure 3: Grouting on page 16) with foundation bolts extending through
holes in the baseplate. Metal wedges with a small taper may be used in lieu of blocks and shims.
If the unit has a non-flexible coupling, the coupling halves should be disconnected; this is generally not
necessary on flexible type couplings.
Tighten up all pump and motor bolts to assure they have not loosened or a soft foot has occurred due to
base distortion in shipment.
Figure 3: Grouting
If driver is being field installed, it should be centered in its bolt holes with shims added to bring the motor
into rough alignment with the pump.
NOTICE:
Do not exceed six (6) shims, using as thick a shim as possible, otherwise, sponginess or soft
foot will result
For 3299 frame mounted pumps, level and plumb the pump shaft, coupling faces and flanges by adding
or removing shims between the blocks and bottom of the base. Hand tighten the anchor bolt nuts at first
being very careful not to distort the base, snug down the nuts with a wrench. The non-flexible coupling
should not be reconnected until the alignment operation has been completed.

For 3299 close coupled pumps, level and plumb the pump flanges, with the motor foot bolts loosened, by
adding or removing shims between the blocks and bottom of the base. Hand tighten the anchor bolt nuts
at first. Being careful not to distort the base, snug down the nuts with a wrench. Recheck that the pump
flanges have remained level and plumb. Next tighten the motor foot bolts, being careful to recheck that
the pump flanges remain level and plumb. Shimming of the motor may be required to maintain align-
ment.
NOTICE:
The baseplate does not have to be level.
After foundation bolts are lightly torqued, recheck alignment requirements once more. Follow require-
ments outlined at the beginning of this section. Add
or remove shims under the base and snug anchor bolts until rough alignment tolerances are met.

Then the unit can be grouted in (See Figure 3: Grouting on page 16).

Model 3299 Installation Operation Maintenance 17

Grout compensates for the uneven foundation. Together with the baseplate, it makes a very rigid inter-
face between the pump and foundation distributing the weight over the length of the base and prevents
shifting.
Use an approved, non-shrinking grout such as Embeco 636 or 885 by Master Builders, Cleveland, Ohio
or equivalents. This is an iron filings style grout.
Grouting procedure
1. Build a strong form around the foundation to contain the grout.
2. Soak the top of the foundation thoroughly, then remove surface water.
3. The baseplate should be completely filled with grout and if necessary, temporarily use air relief
tubing or drill vent holes to remove trapped air.

Figure 7: Alternate alignment method
4. After the grout has thoroughly hardened (approximately 24 hours) tighten the foundation bolts
fully.
5. Check the alignment after the foundation bolts are tightened.
