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
2 Model HS Installation, Operation, and Maintenance Manual

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.
1.3 Safety
Definitions
Throughout this manual the words Warning, Caution, and Electrical are used to indicate where special
operator attention is required.
Observe all Cautions and Warnings highlighted in the Pump Safety Manual and the IOM provided with
your equipment.
WARNING:
Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
Example: Pump shall never be operated without coupling guard installed correctly.
CAUTION:
Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.
Example: Throttling flow from the suction side may cause cavitation and pump damage.

Model HS Installation, Operation, and Maintenance Manual 3

WARNING NEVER use heat to disassemble pump due to risk of explosion from tapped
liquid.
WARNING NEVER operate pump without coupling guard correctly installed.
WARNING NEVER run pump below recommended minimum flow when dry, or without
prime.
WARNING ALWAYS lock out power to the driver before performing pump maintenance.
WARNING NEVER operate pump without safety devices installed.
WARNING NEVER operate pump with discharge valve closed.
WARNING NEVER operate pump with suction valve closed.
WARNING DO NOT change service application without approval of an authorized ITT
Goulds Pumps representative.
WARNING Safety Apparel:
•Insulated work gloves when handling hot bearings or using bearing
heater
• Heavy work gloves when handling parts with sharp edges, especially
impellers
• Safety glasses (with side shields) for eye protection
• Steel-toed shoes for foot protection when handling parts, heavy tools,
etc.
• Other personal protective equipment to protect against hazardous/toxic
fluids
WARNING Receiving:
Assembled pumping units and their components are heavy. Failure to properly
lift and support equipment can result in serious physical injury and/or equip-
ment damage. Lift equipment only at specifically identified lifting points or as
instructed in the current IOM. Current manuals are available at www.gould-
spumps.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:
1.4 General precautions
4 Model HS Installation, Operation, and Maintenance Manual

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 Never operate a pump without coupling guard properly installed. Personal in-
jury will occur if pump is run without coupling guard.
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 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 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.
1.4 General precautions
Model HS Installation, Operation, and Maintenance Manual 5

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.
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.

2 General Information
2.1 Preparation for shipment
Goulds pumps are prepared at the factory for shipment under covered conditions. They are protected for
transport and short term covered storage. Unless otherwise specified, it is assumed the pump will be in-
stalled upon delivery. Additional protection can be provided by request.
2.2 Installation
Location of unit
The pump should be located in a clean, dry area free from flooding. The area should provide adequate
space for maintenance and repair, considering complete disassembly and handling of equipment. The
unit should be positioned to provide the most efficient pipeline system.
Piping
Short, direct suction and discharge pipelines and a minimum of elbows and fittings result in the least
amount of pipe friction.
Suction piping
1. Excessive Friction losses will cause cavitation.
2. Must be kept free of air leaks, particularly in long lines or conditions of high suction lift.
3. Flow regulating valves must not be located on suction side of the pump.
Discharge piping
1. Excessive friction losses result in insufficient head.
2. A check valve should be located in the discharge line to protect the pump from reverse flow and
excessive pressure.
Piping support
The pumps are not designed to carry loads imposed by the weight of the pipeline. Suction and discharge
piping must be supported near the pump, unless otherwise specified. Pumps and sub-bases can be de-
signed to carry loads due to thermal expansion.
Foundation
The foundation must be a permanent, rigid support for the sub-base or floor-plate. It should be an indus-
trially accepted design capable of absorbing excessive vibration. Foundations are typically concrete with
anchor bolts cast into secure the pump.
An anchor bolt assembly consists of a bolt and washer with a sleeve 2 times the diameter of the bolt.
When the assembly is cast in concrete, the washer prevents the sleeve and bolt from being pulled. The
sleeve I.D. provides an adjustment allowance around the bolt. A lug is generally welded on the bolt to
prevent rotation when tightening. Anchor bolts should be located in the concrete by a template dimen-
sioned from the pump installation drawing. The top of the sleeve should be temporarily sealed with waste
material to prevent concrete from entering during the concrete pouring operation.
2 General Information
Model HS Installation, Operation, and Maintenance Manual 7

Figure 1: Typical anchor bolt
Installing Pump on Foundation
If sub-bases or floor-plates were directly anchored to poured concrete foundations, surface irregularities
would cause distortion. Rectangular metal blocks and shims, or metal wedges having a small taper, are
placed beside each anchor bolt to level the sub-base or floor-plate, see Figures below, Leveling with
Wedges and Leveling with Blocks and Shims. The anchor bolts are then drawn tight enough to maintain
position and level.
Figure 2: Leveling with wedges
To secure the shims in place and provide a level surface for the base or plate, grout is poured over the
concrete foundation. A ¾" to 1-½" grout allowance is recommended. When subbases have cavities,
grout holes are provided to fill all spaces. After the grout has hardened, permanently tighten the anchor
bolts.
