FOREWORD
This manual provides instructions for the Installation, Operation, and Maintenance of the
Goulds Models 3196, CV 3196, HT 3196, LF 3196, NM 3196, 3198, and 3796. This manual
covers 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 power
end. 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. The
design, materials, and workmanship incorporated in the construction of Goulds pumps makes
them capable of giving long, trouble-free service. The life and satisfactory service of any
mechanical unit, however, is enhanced and extended by correct application, proper installation,
periodic inspection, condition monitoring and careful maintenance. This instruction manual was
prepared to assist operators in understanding the construction and the correct methods of
installing, 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 symbol
must be followed. Personal injury and/or equipment damage may occur if these instructions are
not followed. If there is any question regarding these requirements or if the equipment is to be
modified, 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 by
calling 1-800-446-8537.

DEFINITIONS .................................. 7
GENERAL PRECAUTIONS........................... 7
DEFINITIONS
These pumps have been designed for safe and
reliable operation when properly used and maintained
in accordance with instructions contained in this
manual. A pump is a pressure containing device with
rotating parts that can be hazardous. Operators and
maintenance personnel must realize this and follow
safety measures. Goulds Pumps shall not be liable
for physical injury, damage or delays caused by a
failure to observe the instructions in this manual.
Throughout this manual the words WARNING,
CAUTION,ELECTRICAL, ATEX, and NOTE are
used to indicate procedures or situations which
require special operator attention:
s
!WARNING
Operating procedure, practice, etc. which, if not
correctly followed, could result in personal
injury or loss of life.
l
!CAUTION
Operating procedure, practice, etc. which, if not
followed, could result in damage or destruction
of equipment.
If equipment is to be installed in a
potentially explosive atmosphere and these
procedures are not followed, personal
injury or equipment damage
from an explosion may result.
Particular care must be taken when
electrical power source to the equipment is
energized.
NOTE: Operating procedure, condition, etc.
which is essential to observe.
EXAMPLES
s
!WARNING
Pump shall never be operated without coupling
guard installed correctly.
l
!CAUTION
Throttling flow from the suction side may cause
cavitation and pump damage.
Improper impeller adjustment could cause
contact between the rotating and
stationary parts, resulting in a spark and
heat generation.
Lock out driver power to prevent electric
shock, accidental start-up and physical
injury.
NOTE: Proper alignment is essential for long
pump life.

GENERAL PRECAUTIONS
s
!WARNING
Personal injuries will result if procedures
outlined in this manual are not followed.
s
!NEVER apply heat to remove impeller. It may
explode due to trapped liquid.
s
!NEVER use heat to disassemble pump due to
risk of explosion from trapped liquid.
s
!NEVER operate pump without coupling guard
correctly installed.
l
!NEVER operate pump beyond the rated
conditions to which the pump was sold.
l
!NEVER start pump without proper prime (all
models), or proper liquid level in self-priming
pumps (Model 3796).
l
!NEVER run pump below recommended
minimum flow or when dry.
s
!ALWAYS lock out power to the driver before
performing pump maintenance.
s
!NEVER operate pump without safety
devices installed.
s
!NEVER operate pump with discharge valve
closed.
l
!NEVER operate pump with suction valve
closed.
DO NOT change conditions of service
without approval of an authorized Goulds
representative.
EXPLOSION PREVENTION
In order to reduce the possibility of accidental explosions in atmospheres containing explosive
gasses and/or dust, the instructions under the ATEX symbol must be closely followed. ATEX
certification is a specification enforced in Europe for non- electrical and electrical equipment
installed in Europe. The usefulness of the ATEX requirements are not limited to Europe, and
are useful guidelines for equipment installed in any potentially explosive environment.
SPECIAL ATEX CONSIDERATIONS
All installation and operation instructions in this manual
must be strictly adhered to. In addition, care must be
taken to ensure that the equipment is properly
maintained. This includes but is not limited to:
1. Monitoring the pump frame and liquid end
temperature.
2. Maintaining proper bearing lubrication.
3. Ensuring that the pump is operated in the
intended hydraulic range.
8ANSIFAM IOM - 12/03

ATEX IDENTIFICATION
For a pumping unit (pump, seal, coupling, motor and
pump accessories) to be certified for use in an ATEX
classified environment, the proper ATEX identification
must be present.
The ATEX tag would be secured to the pump or the
baseplate on which it is mounted. A typical tag would
look like this:
The CE and the Ex designate the ATEX compliance.
The code directly below these symbols reads as
follows:
II = Group 2
2 = Category 2
G/D = Gas and Dust present
T4 = Temperature class, can be T1 to T6
(see Table 1)
Table 1
Code
Max permissible
surface temperature
oF (oC)
Max permissible
liquid temperature
oF (oC)
T1 842 (450) 700 (372)
T2 572 (300) 530 (277)
T3 392 (200) 350 (177)
T4 275 (135) 235 (113)
T5 212 (100) Option not available
T6 185 (85) Option not available
The code classification marked on the equipment
should be in accordance with the specified area
where the equipment will be installed. If it is not,
please contact your ITT/Goulds representative before
proceeding.
INTENDED USE
The ATEX conformance is only applicable when the
pump unit is operated within its intended use. All
instructions within this manual must be followed at all
times. Operating, installing or maintaining the pump
unit in any way that is not covered in this manual can
cause serious personal injury or damage to the
equipment. This includes any modification to the
equipment or use of parts not provided by ITT/Goulds.
If there is any question regarding the intended use of
the equipment, please contact an ITT/Goulds
representative before proceeding.
CONDITION MONITORING
For additional safety precautions, and
where noted in this manual, condition
monitoring devices should be used. This
includes, but is not limited to:
♦Pressure gauges
♦Flow meters
♦Level indicators
♦Motor load readings
♦Temperature detectors
♦Bearing monitors
♦Leak detectors
♦PumpSmart control system
For assistance in selecting the proper instrumentation
and its use, please contact your ITT/Goulds
representative.
