Pump Safety Tips

Safety Apparel:

Insulated work gloves when handling hotbearings or using bearing heater

Heavy work gloves when handling parts withsharp edges, especially impellers

Safety glasses (with side shields) for eyeprotection, especially in machine shop areas

Steel-toed shoes for foot protection whenhandling parts, heavy tools, etc.

Other personal protective equipment to protectagainst hazardous/toxic fluids

Coupling Guards:

Never operate a pump without a coupling guardproperly installed

Flanged Connections:

Never force piping to make a connection with apump

Use only fasteners of the proper size andmaterial

Ensure there are no missing fasteners

Beware of corroded or loose fasteners

Operation:

Do not operate below minimum rated flow, orwith suction/discharge valves closed

Do not open vent or drain valves, or removeplugs while system is pressurized

Maintenance Safety:

Always lock out power

Ensure pump is isolated from system andpressure is relieved before disassembling pump,removing plugs, or disconnecting piping

Use proper lifting and supporting equipment toprevent serious injury

Observe proper decontamination procedures

Know and follow company safety regulations

Observe all cautions and warnings highlighted inpump Installation, Operation and MaintenanceInstructions.

FOREWORDThis manual provides instructions for the Installation, Operation, and Maintenance of theGoulds Models 3196, CV 3196, HT 3196, LF 3196, NM 3196, 3198, and 3796. This manualcovers the standard product plus common options that are available. For special options,

supplemental instructions are supplied. This manual must be read and understood before

installation and start-up.

This instruction manual covers several different pump models that all have a common powerend. Most assembly, disassembly, and inspection procedures are the same for all the pumps.However, where there are differences, they are called out separately within the manual. Thedesign, materials, and workmanship incorporated in the construction of Goulds pumps makesthem capable of giving long, trouble-free service. The life and satisfactory service of anymechanical unit, however, is enhanced and extended by correct application, proper installation,periodic inspection, condition monitoring and careful maintenance. This instruction manual wasprepared to assist operators in understanding the construction and the correct methods ofinstalling, operating, and maintaining these pumps.

Goulds shall not be liable for physical injury, damage, or delays caused by a failure to

observe the instructions for installation, operation, and maintenance contained in this

manual.

When intalled in potentially explosive atmospheres, the instructions that follow the Ex symbolmust be followed. Personal injury and/or equipment damage may occur if these instructions arenot followed. If there is any question regarding these requirements or if the equipment is to bemodified, please contact a Goulds representative before proceeding.

Warranty is valid only when genuine Goulds parts are used.

Use of the equipment on a service other than stated in the order will nullify the warranty,unless written approval is obtained in advance from Goulds Pumps.

Supervision by an authorized Goulds representative is recommended to assure proper installation.

Additional manuals can be obtained by contacting your local Goulds representative or bycalling 1-800-446-8537.

DEFINITIONS

These pumps have been designed for safe andreliable operation when properly used and maintainedin accordance with instructions contained in thismanual. A pump is a pressure containing device withrotating parts that can be hazardous. Operators andmaintenance personnel must realize this and followsafety measures. Goulds Pumps shall not be liablefor physical injury, damage or delays caused by afailure to observe the instructions in this manual.

Throughout this manual the words WARNING,CAUTION, ELECTRICAL, ATEX, and NOTE areused to indicate procedures or situations whichrequire special operator attention:

! WARNINGOperating procedure, practice, etc. which, if notcorrectly followed, could result in personalinjury or loss of life.

! CAUTIONOperating procedure, practice, etc. which, if notfollowed, could result in damage or destructionof equipment.

If equipment is to be installed in apotentially explosive atmosphere and theseprocedures are not followed, personalinjury or equipment damagefrom an explosion may result.

Particular care must be taken whenelectrical power source to the equipment isenergized.

NOTE: Operating procedure, condition, etc.which is essential to observe.

EXAMPLES

! WARNINGPump shall never be operated without couplingguard installed correctly.

! CAUTIONThrottling flow from the suction side may causecavitation and pump damage.

Improper impeller adjustment could causecontact between the rotating andstationary parts, resulting in a spark andheat generation.

Lock out driver power to prevent electricshock, accidental start-up and physicalinjury.

NOTE: Proper alignment is essential for longpump life.

GENERAL PRECAUTIONS

! WARNINGPersonal injuries will result if proceduresoutlined in this manual are not followed.

! NEVER apply heat to remove impeller. It mayexplode due to trapped liquid.

! NEVER use heat to disassemble pump due torisk of explosion from trapped liquid.

! NEVER operate pump without coupling guardcorrectly installed.

! NEVER operate pump beyond the ratedconditions to which the pump was sold.

! NEVER start pump without proper prime (allmodels), or proper liquid level in self-primingpumps (Model 3796).

! NEVER run pump below recommendedminimum flow or when dry.

! ALWAYS lock out power to the driver beforeperforming pump maintenance.

! NEVER operate pump without safetydevices installed.

! NEVER operate pump with discharge valveclosed.

! NEVER operate pump with suction valveclosed.

DO NOT change conditions of servicewithout approval of an authorized Gouldsrepresentative.

EXPLOSION PREVENTION

In order to reduce the possibility of accidental explosions in atmospheres containing explosivegasses and/or dust, the instructions under the ATEX symbol must be closely followed. ATEXcertification is a specification enforced in Europe for non- electrical and electrical equipmentinstalled in Europe. The usefulness of the ATEX requirements are not limited to Europe, andare useful guidelines for equipment installed in any potentially explosive environment.

SPECIAL ATEX CONSIDERATIONS

All installation and operation instructions in this manualmust be strictly adhered to. In addition, care must betaken to ensure that the equipment is properlymaintained. This includes but is not limited to:

1. Monitoring the pump frame and liquid endtemperature.

2. Maintaining proper bearing lubrication.

3. Ensuring that the pump is operated in theintended hydraulic range.

ATEX IDENTIFICATION

For a pumping unit (pump, seal, coupling, motor andpump accessories) to be certified for use in an ATEXclassified environment, the proper ATEX identificationmust be present.

The ATEX tag would be secured to the pump or thebaseplate on which it is mounted. A typical tag wouldlook like this:

The CE and the Ex designate the ATEX compliance.The code directly below these symbols reads asfollows:

II = Group 2

2 = Category 2

G/D = Gas and Dust present

T4 = Temperature class, can be T1 to T6
