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.

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.

equipment damage. Lift 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.
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. Failure 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 misalign-
ment between pump and driver. Pipe strain will adversely effect the operation
of the pump resulting in physical injury 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 fasten-
ers.
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 clearance 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 certi-
fied and must be constructed from a non-sparking material.
WARNING Never operate a pump without coupling guard properly installed. Personal in-
jury will occur if pump is run without coupling guard.
1.4 General precautions
6 VIS Installation, Operation and Maintenance Instructions

WARNING Make sure to properly lubricate the bearings. Failure to do so may result in ex-
cess heat generation, sparks, and / or premature failure.
CAUTION The mechanical seal used in an ATEX classified environment must be proper-
ly certified. Prior to start up, ensure all points of potential leakage of process
fluid to the work environment are closed.
CAUTION Never operate the pump without liquid supplied to mechanical seal. Running a
mechanical 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 dis-
charge valve closed. These conditions may create an explosive hazard due to
vaporization of pumpage and can quickly lead to pump failure and physical in-
jury
WARNING Ensure pump is isolated from system and pressure is relieved before disas-
sembling pump, removing plugs, opening vent or drain valves, or disconnect-
ing 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 decon-
tamination procedures. Proper personal protective equipment should be worn.
Precautions must be taken to prevent physical injury. Pumpage must be han-
dled and disposed of in conformance with applicable environmental regula-
tions.
WARNING Operator must be aware of pumpage and safety precautions to prevent physi-
cal 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 pre-
vent physical 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 properly 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 explo-
sion due to trapped fluid, resulting in severe physical injury and property dam-
age.
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.
1.4 General precautions
VIS Installation, Operation and Maintenance Instructions 7

WARNING Noise:
Sound pressure levels may exceed 80 dbA in operating process plants. Clear
visual warnings or other indicators should be available to those entering an
area with unsafe noise levels. Personnel should wear appropriate hearing pro-
tection when working on or around any equipment, including pumps. Consider
limiting personnel’s exposure time to noise or, where possible, enclosing
equipment to reduce noise. Local law may provide specific guidance regard-
ing exposure of personnel to noise and when noise exposure reduction is re-
quired.
WARNING Temperature:
Equipment and piping surfaces may exceed 130ºF (54ºC) in operating proc-
ess plants. Clear visual warnings or other indicators should alert personnel to
surfaces that may reach a potentially unsafe temperature. Do not touch hot
surfaces. Allow pumps operating at a high temperature to cool sufficiently be-
fore performing maintenance. If touching a hot surface cannot be avoided,
personnel should wear appropriate gloves, clothing, and other protective gear
as necessary. Local law may provide specific guidance regarding exposure of
personnel to unsafe temperatures.
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
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.
Current IOMs are available at https://www.gouldspumps.com/en-US/Tools-and-Resources/Literature/

3 Storage
3.1 Storage
Goulds Pumps carefully preserves and protects its products for shipment. However, the effective life of
the preservatives applied at the factory can vary from 3 to 18 months depending on the severity of the
environment in which the equipment is stored. This section provides procedures for preparation prior to
storage and maintenance during storage of Goulds' pumps.
These procedures are necessary to protect the precision parts of the pumps. Specific procedures
for storing motors should be obtained from the motor manufacturer. This section is intended to be of gen-
eral assistance to users of Goulds pumps. It shall not modify, amend, and/or otherwise alter the scope of
Goulds Pumps warranty in anyway whatsoever.
3.2 Storage Preparation
Goulds' submersible pumps require proper preparation for storage. The pump shall be considered in
storage when it has been delivered to the job site and is awaiting installation. If a pump has been instal-
led, but is not in regular operation, such as seasonal shutdown or an extended period of time, it is sug-
gested that the pump be operated for at least 15 minutes every two weeks if possible.
3.3 Recommended Storage Procedures
1. Controlled storage facilities should be main tained at an even temperature 10°F or more above
the dew point with relative humidity less than 50% and little or no dust. (If these requirements
cannot be met the pump is to be considered in uncontrolled storage.)
2. For uncontrolled storage periods of six months or less, the pump is to be inspected periodically to
insure that all preservatives are intact.
3. All pipe threads and flanged pipe covers are to be sealed with tape.
4. The pump must not be stored closer than six inches to the ground.
3.4
Preparations for Uncontrolled Long Term Storage
• Storage periods over six months require the preceding uncontrolled storage procedure plus the fol-
lowing:
1. Inspect the assembly and recoat periodically to prevent corrosion.
2. Place ten pounds of moisture absorbing dessicant or five pounds of vapor phase inhibitor crys-
tals near the center of the pump. If the pump is assembled, place an additional one pound in
the discharge nozzle securely fastened to the dis charge flange.
3. Install a moisture indicator near the perimeter of the pump. Cover the pump with 6 mils mini-
mum thickness black polyethylene or equal and seal it with tape. Provide a small ventilation
hole approximately½ inch diameter.
4. Provide a roof or a shed shelter to protect from direct exposure to the elements.

5 Pump Installation
5.1 Pump Installation
NOTICE:
Pump Installation: All bolts are torqued by the factory and secured with Loctite. It is recognized
that transportation and handling may result in bolt relaxation, therefore, check that all fasteners
on the pump are tight prior to installation.
• Preliminary precautions should be taken prior to the final installation of the pump. The well and well
site should be examined carefully in the following manner.
1. Check to insure sand has not covered the perforated sections of the well.
2. Determine that the well is of ample diameter and depth and is sufficiently straight to receive the
pump. The submersible unit must be operated in a straight portion of the well. Exerted pres-
sures can and will cause misalignment of bearings or
couplings. When the straightness of the well is not known, it is recommended to lower a test blank
with the same diameter and length as the combined pump/motor assembly with electrical leads into
the well to the desired depth. If there is any doubt about straightness, caging and plotting are rec-
ommended.
CAUTION:
Never install unit with the bottom of the motor closer than five feet from the bottom of the well.
NOTICE:
In a previously used well, any obstruction such as jagged casing or other damage should be
removed or corrected. Visual inspection may be performed through the use of an underwater
television camera.
3. Any oil or oil emulsion must be removed from the surface of the water to prevent premature
damage to the unit. It is possible to prevent fluid from entering the unit during installation by
wrapping with an envelope of water soluble polyvinyl alcohol, but this will not protect the jacket
material of the electrical conductor.
4. Survey the well
Many wells have more than one size of casing installed and frequently the lower sections are small-
er in diameter than the upper casing.
CAUTION:
Do not install the unit with the motor in mud, sand, or resting on the bottom of the well. It is
important to prevent the well from sanding up at any time to the point that the motor becomes
even partially buried.
5.2 Preparing the Foundation
The foundation must be rigid, level, and of adequate strength to support the complete weight of the
pump, motor, column, plus the weight of the liquid passing through it. It is recommended the foundation
5 Pump Installation
16 VIS Installation, Operation and Maintenance Instructions

be constructed of solid concrete, how ever, adequate beams or timbers may be used. A common founda-
tion consists of the following concrete mixture:
1. One part cement
2. Two parts sand
3. Four parts gravel with sufficient water to make a stiff mix
5.3 Preparation for Installation
• Lay out of the column pipe and bowl/motor assembly on suitable timbers keeping all material out of
the dirt. Pipe coupling ends should be located towards the well. Clean all threads thoroughly and
coat with joint compound as installed. All other parts should be laid out in the order in which they
will be used.
5.4 Checking Resistance
Before removing shipping skids, resistance of motor and cables should be checked with a proper instru-
ment such as a megger. Make cable splice, if not already done at the factory, as follows:
1. Tape cable splice
a) Snip outer jacket in two or three places and remove jacket, with Sta-Kon or other similar pliers,
peeling jacket back approximately one foot. Remove any cotton or other tape from individual
conductors in order to expose the insulation of each wire. Strip the insulation of each conductor
back far enough to allow the conductor to extend half way through a sleeve type connector.
Crimp connector to the conductor. Strip motor lead insulation back far enough to fit into connec-
tor and butt against cable end. Crimp connector as before. Pull on wire to make sure connector
is firmly crimped to both the motor lead and cable. Scrape the insulation to remove any loose
bits of tape or thread and roughen surfaces. Thoroughly clean surfaces with a solvent (Naph-
tha, lacquer thinner, etc.). This will insure a watertight splice.
b) Using a self-bonding polyethylene based tape, start a the center of the connector and tape one
inch past end of connector, stretching tape about 10% while taping. Overlap tape about one
half of tape width. Continue taping back past connector one inch on the other side. This com-
pletes the first layer of tape. Upon completing each layer, coat tape with Scotch-Kate electrical
coating 31KBB or a similar material. Tape next layer back past connector one inch farther than
the first wrap so that the conductor is now taped two inches from the end of the connector. This
completes the second layer. Tape back past the center again to opposite end, this time one
inch farther than the second layer of tape, completing the third layer.
c) Tape back to the center and cut off the tape. Connector has now been taped at center with four
layers of half lapped tape. Using vinyl plastic electrical tape, start at the center of the splice and
tape one inch past the end of the insulating tape. Stretch the tape about 25% while taping and
overlap about one-half tape width. Wrap to the other end, past the center of the splice and one
inch past the end of the polyethylene based tape, thus completing the fifth layer. Tape sixth and
seventh layers, extending each layer one inch past the previous one.
d) To finish the taped splice, tape back to the center and cut the tape off. The overall length of the
taped splice should be approximately 12" long and have eight layers of tape, four insulating
and four jacketing.
2. Cast Cable Splice
a) To prepare the 3-conductor power cable for splicing, insert a sharp knife blade between the ca-
ble jacket and the lead insulation and strip the jacket back 2½" from the end, taking care not to
cut the lead insulation. Strip the cambric wrapping (if any) off of the conductors and strip back
rubber insulation 5/e" from the end. Assemble the cable connectors and crimp them in place
using a crimping tool. If cables are too large for the connectors, cut off enough strands to re-
duce them to the size of the connectors.
5.3 Preparation for Installation
VIS Installation, Operation and Maintenance Instructions 17

b) Cut off the motor leads to equal length. Clean off the ends of the leads for about a foot, using a
cloth wet with gasoline or solvent. Clean the end of the power cable also. Insert the three motor
leads into the corresponding holes in the bottom of the rubber casing and push them several
inches out the top. Crimp the motor leads into the corresponding connectors, crimping the cen-
ter one first. Bend the cables into line with the holes in the casing and slip the casing up until
the connectors are inside the holes and about ¼" from the top.
c) Mix the resin as directed, but squeeze the bag lightly when mixing, since it may rupture if too
much pressure is applied. Cut off a corner of the bag and squeeze all of the resin into the cas-
ing. With the roll of tape at hand, fold the bag, and tape the top of the bag snugly to the power
cable until the resin runs out over the top. This will assure maximum coverage of the resin and
minimum size of the finished splice. It is not necessary to tape over the top of the casing, since
the resin will seal it. When the resin is firm to the touch, the splice may be immersed for testing
or for final installation.
d) Since the power cable is usually larger than the motor leads, it may be necessary to cut some
of the strands of the larger cable and to fill out the smaller leads by bending some of the
strands double. The use of the proper crimping tool is advised, but if one is not available, a
sound connection can be made by flattening the connectors with a ball peen hammer and mak-
ing one or two indents with a center punch. Avoid crushing the ends of the connectors since
this may cause them to split open.
After splicing is completed, wet the splice and check resistance to ground. This can be achieved in
the following manner:
3. Attach one pole of the megger to ground and the other pole of the megger to any one of the motor
leads.
CAUTION:
The minimum reading for each lead to ground should be 50 megohms.
4. To check phases for continuity, connect the megger poles to two of the three leads, altering until all
three pairs of leads have been checked. Megger readings should all be zero, which indicates con-
tinuous circuit.
NOTICE:
Such a resistance check should be performed during and immediately after the completion of
installation.
5.5 Energizing the Motor
•Secure the pump and motor with chain tongs to resist torque. Energize the motor momentarily (on
and immediately off) to check the rotation.
NOTICE:
Rotation will be counterclockwise when viewed from the discharge bowl.
• If rotation is wrong, interchange any two of the motor leads at the control panel.
CAUTION:
Correct rotation is of extreme importance. Excessive overloads may be developed under oper-
ating conditions with reverse rotation.
