1 Important Safety Notice
2 HSU Installation, Operation and Maintenance Instructions

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.
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.

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:
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.
4 General precautions
6 HSU 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.

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/

7 General
7.1 Introduction
This instruction manual is intended to assist those involved with the installation, operation and mainte-
nance of Goulds SPD slurry pumps. It is recommended that this manual be thoroughly reviewed prior to
installing or performing any work on the pump or motor.
7.2 Importance of instructions
The design, material and workmanship incorporated in the construction of Goulds SPD slurry pumps
makes them capable of giving long, trouble-free service. The life a satisfactory service of any mechanical
unit, however, is enhanced and extended by periodic inspection and careful maintenance. This manual
was prepared to assist operators in understanding the construction and correct methods of installing, op-
erating, and maintaining these pumps.
Keep this manual handy for reference. Further information can be obtained by contacting the Slurry
Pump Division, P.O. Box 419, Baldwinsville, New York, 13027.
7.3 Special warnings
Goulds Slurry Pump Division will not be liable for any damages or delay caused by failure to comply with
the provisions of this instruction manual. This pump is not to be operated at speeds, working pressures,
discharge pressures, or temperatures higher than or used with liquids other than, stated in the original
order acknowledgement, Without written permission of the Slurry Pump Division, Goulds Pumps, Inc.
7.4 Receiving inspection - shortages
Care should be taken when unloading pumps. If shipment is not delivered in good order and in accord-
ance with the bill of lading, note the damage or shortage on both receipt and freight bill. Make any claims
to the transportation company promptly.
7.5 Preservation and storage
Goulds Slurry Pump Division's normal domestic shipping and storage preparation is suitable for protect-
ing the pump during shipment in covered trucks. Although this is a submersible pump, storage in a clean,
dry area will help preserve the paint and prevent corrosion. Hand rotation of the shaft every thirty days is
recommended to keep the seals free and the bearings lubricated.
7.6 Sump installation
The sump floor should be level and firm where the pump will be placed. Make sure the sump and sump
inlet line are free from large pieces of debris which could eventually obstruct the pump inlet.
7.7 Motor installation
The motor is furnished with thermal protection and a moisture probe. Wire the motor according to the
motor manufacturer's wiring diagram. Re-check the protective circuits after the wiring is completed to
avoid a possible motor failure because of an oversight.
The motor has to be completely submerged for continuous operation. It can be operated for a maximum
of 15 minutes without being submerged. The sump controls should be set to allow a maximum possible
7 General
12 HSU Installation, Operation and Maintenance Instructions

run of 15 minutes after the motor is no longer completely submerged if the sump is large enough to not
have completed the pump-down in that time.
The motor is rated for full horsepower with liquid temperatures of 40° C (104° F) or lower.
7.8 Pump installation
Make sure the lifting device is securely fastened to the motor lugs or hooks so the unit will not be drop-
ped when it is lowered into the sump. Check the 1/8" vent hole in the adapter plate, between the motor
and the casing, to make certain it is not plugged and then carefully lower the unit into position in the
sump. Check the pump for being approximately level. Support the discharge pipe to prevent excessive
loads from being transmitted to the pump flange and casing.
7.9 Starting the pump
The most important concern is the prevention of motor overloading. Refer to the motor nameplate for the
full load ampere rating of the motor. Install an ammeter on the motor leads and check the motor draw
immediately after the unit is started.
An excessive current draw with a 3-phase motor is an indication of wrong rotation.
Observe the discharge for flow rate, then change two of the three motor leads to reverse the direction of
rotation. If the rotation was wrong, the current draw will be reduced at the same or greater flow rate. Sin-
gle phase motors are internally wired for the correct rotation.
The ammeter on the motor leads should be checked for overload at all sump level heights with the liquid
that will be normally pumped to check for motor overload at some other condition from that encountered
at start-up. The horsepower will tend to increase as the level in the sump rises.
7.10 Locating trouble
Insufficient or no discharge can be caused by any of the following conditions:
1. Speed too low (usually due to low voltage)
2. System head too high
3. Insufficient NPSH or submergence
4. Wear of the pump parts
5. Wrong direction of rotation
6. Pump not completely primed (plugged vent hole)
7. Suction opening or discharge pipe clogged
8. Viscosity of slurry too high
7.11 Excessive current draw
Excessive current draw may be caused by any of the following conditions:
1. Wrong direction of rotation
2. Pump operating at a high horsepower area of the pump curve (capacity is greater than the de-
sign capacity)
3. Impeller rubbing or mechanical defect in the motor
4. Specific gravity or viscosity too high.
5. Low voltage
