• If the pump or motor is damaged or leaking, electric shock, fire, explosion, liberation of
toxic fumes, physical harm, or environmental damage may result. Do not operate the unit
until the problem has been corrected or repaired.
• Risk of serious personal injury or property damage. Dry running may cause rotating parts
within the pump to seize to non-moving parts. Do not run dry.
• Risk of death, serious personal injury, and property damage. Heat and pressure buildup
can cause explosion, rupture, and discharge of pumpage. Never operate the pump with
suction and/or discharge valves closed.
• Running a pump without safety devices exposes operators to risk of serious personal in-
jury or death. Never operate a unit unless appropriate safety devices (guards, etc.) are
properly installed. See specific information about safety devices in other sections of this

WARNING:
•When equipment/pumping unit is installed/operated in a potentially explosive atmosphere,
the instructions after the Ex symbol must be followed and equipment must be installed in
accordance with the following instructions. Personal injury and/or equipment damage
from an explosion 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.
• Particular care must be taken when the electrical power source to the equipment is ener-
gized.
• 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.
• NEVER start pump without proper prime (all models), or proper liquid level in self-priming
pumps (Model 3796 and SP3298).

• All equipment being installed must be properly grounded to prevent unexpected static
electric discharge. This includes ensuring that the PFA lined pumps (Model 3198), ETFE
lined pumps (Model 3298, SP3298, V3298), and the non-metallic liquid end pumps (Mod-
el NM3196) are pumping fluids that are conductive. If not, a static electric discharge may
occur when the pump is drained and disassembled for maintenance purposes
• When pumping fluids with conductivity less than 1000 ps/m follow IEC TS 60079 32-1
guidelines.
• Alignment procedures must be followed to prevent unintended contact of rotating parts.
Follow coupling manufacturer’s installation and operation procedures.
• When installing in a potentially explosive environment, ensure that the motor and acces-
sories are properly certified.
• The impeller clearance setting procedure must be followed. Improperly setting the clear-
ance or not following any of the proper procedures can result in sparks, unexpected heat
generation and equipment damage.
• The impeller and wear ring clearance setting procedures 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.
• Service temperature in an ATEX classified environment is limited to the area classification
specified on the ATEX tag affixed to the pump (reference Table 1 in the Safety section for
ATEX classifications).
• The coupling used in an ATEX classified environment must be properly certified.
• The coupling guard used in an ATEX classified environment must be constructed from a
non-sparking material.
• Bearings must be lubricated properly in order to prevent excess heat generation, sparks
and premature failure.
• The mechanical seal used in an ATEX classified environment must be properly certified.
• The mechanical seal must have an appropriate seal flush system. Failure to do so will re-
sult in excess heat generation and seal failure.
• Packed Stuffing Boxes and/or Dynamic Seals are not allowed in an ATEX classified envi-
ronment.
• Pumps that are not self-priming must be fully primed at all times during operation. The
only model lines that are self-priming is the 3796 and SP3298.
• Pumps must be fully primed at all times during operation.
• The preventive maintenance section must be adhered to in order to keep the applicable
ATEX classification of the equipment. Failure to follow these procedures will void the
ATEX classification for the equipment. Bearing replacement intervals are given in the spe-
cific pump model IOM.
• Inspection intervals should be shortened appropriately if the pumpage is abrasive and/or
corrosive, or if the environment is classified as potentially explosive.
• Throughout this section on bearing lubrication, different pumpage temperatures are listed.
If the equipment is ATEX certified and the listed temperature exceeds the applicable val-
ue shown in Table 1 under SAFETY, then that temperature is not valid. Should this situa-
tion occur, please consult with your ITT/Goulds representative.
• Cooling systems, such as those for bearing lubrication, mechanical seal systems, etc.,
where provided, must be operating properly to prevent excess heat generation, sparks
and premature failure.
• Rotate shaft by hand to ensure it rotates smoothly and there is no rubbing which could
lead to excess heat generation, sparks and premature failure.
1.4 ATEX Considerations and Intended Use
14 3610 i-FRAME API 610 11th Ed/ISO 13709 2nd Ed, API Type BB1 Single-Stage, Axially-Split, Between-Bearing IOM

• Flange loads from the piping system, including those from thermal expansion of the pip-
ing, must not exceed the limits of the pump. Casing deformation can result in contact with
rotating parts which can result in excess heat generation, sparks and premature failure.
• Ensure that pump and systems are free of foreign objects before operating and that ob-
jects cannot enter the pump during operation. Foreign objects in the pumpage or piping
system can cause blockage of flow which can result in excess heat generation, sparks
and premature failure.
• Do not insulate or allow the bearing housings to accumulate a dust layer as this can result
in excess heat generation, sparks and premature failure.
• Check for magnetism on the pump shaft and demagnetize the shaft if there is any detect-
able magnetism. Magnetism will attract ferritic objects to the impeller, seals and bearings
which can result in excess heat generation, sparks and premature failure.
• Leakage of process liquid may result in creation of an explosive atmosphere. Ensure the
materials of the pump casing, impeller, shaft, sleeves, gaskets and seals are compatible
with the process liquid.
• Leakage of process liquid may result in creation of an explosive atmosphere. Follow all
pump and seal assembly procedures.
• A buildup of gases within the pump, sealing system and or process piping system may
result in an explosive environment within the pump or process piping system. Ensure
process piping system, pump and sealing system are properly vented prior to operation.
• Sealing systems that are not self purging or self venting, such as plan 23, require manual
venting prior to operation. Failure to do so will result in excess heat generation and seal
failure.
• Do not apply additional paint or coatings to the pump when in an ATEX environment.
Static electric discharge can be initiated when contacting or rubbing surfaces with exces-
sive coating thickness.
• Potential electrostatic charging hazard. Do not rub, clean, or blast equipment with dry
cloth or dry media.
• Stray electrical currents may ignite explosive atmospheres. Ensure drives are certified for
variable frequency drive operation by the manufacturer.
• User shall observe necessity of using a safety device, such as a flame arrestor, to prevent
flame entering or leaving the pump sump, tank, or barrel when applicable.
• For variable speed motor applications, the electric motor must be specified with shaft
grounding and used with a conductive type coupling suitable for the area classification.
• In plants or pumps with cathodic corrosion protection, a small current constantly flows
through the construction. This is not permissible on the complete pump or partially-as-
sembled machinery without further precautions being taken. ITT should be consulted in
this context.
