1.2 Safety
Model 3498 Installation, Operation, and Maintenance Manual 7

WARNING:
•Equipment that will operate in a potentially explosive environment must be installed in ac-
cordance with the following instructions.
• All equipment being installed must be properly grounded to prevent unexpected static
electric discharge. If not, a static electric discharge may occur when the pump is drained
and disassembled for maintenance purposes.
• All equipment being installed must be properly grounded to prevent unexpected static
electric discharge.
• 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. See nameplate section and pumpage tem-
perature table.
• 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 are not allowed in an ATEX classified environment.
• Dynamic seals are not allowed in an ATEX classified environment.
• 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 this
section.
• 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.
1.2 Safety
8 Model 3498 Installation, Operation, and Maintenance Manual

• 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 adequate shaft ground
measures are applied. Ensure drives are certified for variable frequency drive operation
by the manufacturer. Use ground brushes on VFD motor applications with conductive
couplings or ensure pump shaft is adequately grounded.
• 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.
• 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.
1.2.4.1 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.

2.3.1 Pump storage requirements
Consider a unit to be in storage when any of these conditions apply:
•It has been delivered to the job site and is awaiting installation.
• It has been installed, but operation is delayed pending completion of planned construction.
• There are long periods (30 days) between operation cycles.
• The plant or department is shut down.
Store accessories such as motors, steam turbines, and gears according to the recommendations of the
respective manufacturers.
2.3.1.1 Temporary storage
Storage time
These guidelines apply to horizontal and vertical pumps for storage of one month or less.
If the equipment will not be installed and operated soon after arrival, then provide these conditions for
storage:
• Clean, dry, well-ventilated location
• Free from vibrations
• Free from rapid or wide variations in temperatures
Storage maintenance
• Oil-lubricated pumps are shipped without lubricant. Fill the frame completely with oil for storage.
Before putting equipment into operation, drain the oil to the proper level.
• Every week, rotate the shaft several revolutions in order to coat the bearings with lubricant, to re-
tard oxidation or corrosion, and to prevent possible brinelling.
• Coat the shaft extensions and other exposed machine surfaces with an easily removable rust pre-
ventative, such as Tectyl No. 502C from Valvoline Oil Company, Division of Ashland Petroleum
Company.
2.3.1.2 Prepare the pump for long-term storage
CAUTION:
Do not store the pump near sources of vibration, such as near a railroad, heavy truck traffic, or
impacting machinery. Doing so can result in false brinelling of the pump bearings.
The following procedure applies to horizontal and vertical pumps only for storage of one month or longer.
Follow the same guidelines for temporary storage in addition to this procedure.
1. Prepare oil-lubricated bearing frames for storage:
Pumps with oil lubrication are shipped from the factory without oil in the bearing frame. To prepare
these frames for storage, complete these steps:
a) Fill the bearing frame with a lubricating oil that contains a rust preventative such as Mobilarma
500 Series oil.
If this oil will be used for initial operation of the equipment, then take care to select an oil suited to
the intended operating temperature of the pump. Check the supplier’s technical data and the pump
instruction book for this information.
b) Seal all vents and apply a waterproof tape around the oil seals in the bearing frames.
2. Prepare grease-lubricated bearing frames for storage:

Model 3498 Installation, Operation, and Maintenance Manual 15

Pumps are shipped from the factory with the bearings pre-greased and require no further lubrica-
tion.
a) If the pump will be stored in a humid environment or outside, then add 0.5 ounce (14.8 ml) of
corrosion-inhibiting concentrated oil such as Cortec’s VCI-329 to the frame.
b) Seal all vents and apply a waterproof tape around the grease seals in the bearing frame.
3. Prepare the packed stuffing box for storage:
a) Remove the gland, lantern ring, packing base ring (if applicable), and packing from the stuffing
box.
If the packing is in good condition, then it can be saved. Otherwise, discard it.
b) Thoroughly clean and dry the interior of the stuffing box and the shaft sleeve.
c) Coat all interior parts of the stuffing box, except for stainless materials, with a soft film rust pre-
ventative such as Valvoline Tectyl 502C or Cortec’s VCI-369.
d) Seal the end of the stuffing box with waterproof tape.
You will need to remove and replace this tape when you rotate the shaft.
e) Store the gland, packing base ring, packing, and lantern ring until the pump is ready to be put
into service.
4. Prepare the stuffing box with mechanical seal for storage:
A seal box made of stainless material does not require this procedure.
a) For a double-face seal, open uppermost flushing tap on the stuffing box and fill the cavity with a
lightweight (#10-#20) rust preventative oil such as Mobilarma 500.
b) For a single-face seal, remove the flushing-water plug to the stuffing box and spray an oil-base
volatile corrosion inhibitor such as Cortec’s VCI-329 into the stuffing box cavity.
Be sure to coat as much of the interior of the cavity as possible.
c) Seal all vent and drain lines. Seal the point where the shaft exits the box with waterproof tape.
You will need to remove and replace this tape when you rotate the shaft.
Note that most mechanical seals provided have elastomer materials made of Buna-N, Neoprene, or
Viton™, which are not affected by hydrocarbon-based lubricants. If your pump has seals with mate-
rials other than these, then you must check the compatibility of that material with the manufacturer
of the rust preventative used.
5. For pumps made of non-stainless material, complete these steps:
a) Coat all exposed machined surfaces (flanges, faces, shafts, exposed locating fits, and so forth.)
with a firm rust preventative such as Valvoline Tectyl 890.
b) Place a volatile corrosion inhibitor device in the pump casing such as Cortec’s VCI 309, 101, or
110, depending on the pump size and application.
WARNING:
If pumped liquid includes potable water, food, beverage, etc., then the corrosion inhibitor must
be non-toxic. Use of toxic corrosion inhibitors in this circumstance can result in injury or death.
6. Cement the rubber diaphragm flange covers over the suction and discharge flanges. Protect these
rubber diaphragm covers with hardboard material.
7. Make sure all vents, drains, or plugs are tightly sealed.
The pump is now ready to be placed in storage.

2.3.1.3 Storage location and care
Indoor storage and care
Preparation is minimal if the indoor storage area is dry and clean.
•Take care to prevent extremes in temperature (below 32°F [0°C] and above 110°F [43°C]).
• Keep the pump out of direct sunlight.
• Cover the pump in order to protect it from dust and dirt.
• Prevent moisture buildup around the pump, either by allowing proper ventilation or by tightly sealing
the pump in the cover with a suitable amount of desiccant to ensure dryness.
• Rotate the pump shaft 10–15 turns twice a month. This operation recoats the bearings with grease
or oil and prevents false brinelling. Be sure that the shaft comes to rest in different positions.
If the indoor storage area is humid or dirty, such as an unfinished building, treat the pump as if it were to
be stored outdoors.
Outdoor storage and care
• Inspect the storage area weekly, and after storms, for damage to protective covers.
• Rotate the shaft 10–15 turns three times a month.
• Repeat the storage preparation procedure every six months in normal environments and every two
months in corrosive environments, such as salt air.
Installed but not in service
Preparation for storage under these conditions is the same as for indoor and outdoor storage, except
that the suction and discharge piping serve as the flange covers.
• Inspect the casing area once a month for moisture buildup. Replace the volatile corrosion inhibitor
at this time.
• Tightly close the suction and discharge valves and remove all fluid from the pump and attached pip-
ing.
• The interior of the pump and the piping must be thoroughly dried.
• Repeat the storage preparation procedure every 12 months.
2.3.1.4 Prepare the stored pump for operation
1. Remove all rust inhibitor coating from exposed machined surfaces using the method described by
the supplier.
2. Remove all corrosion protection devices or material from the pump casing.
3. If the pump has packing, then repack the pump. See 4.6.1 Packing on page 35.
4. If the pump has mechanical seals, then drain the protective oil from the seal cavity. Flush the cavity
with clean water or seal lubricant for five minutes before startup.
5. Remove the flange covers, tape, and all unnecessary pipe plugs.
6. Prepare the oil-lubricated bearing frame:
a) Drain the rust preventative oil from the frame and replace with fresh oil.
Note that some rust preventative oils such as Mobilarma 500 can be used in the bearing frame for
startup and initial running. Check the supplier’s technical data and 6.3.2.1 Lubricating-oil require-
ments on page 50 in order to make sure that the oil used is of suitable viscosity and grade for the
intended application. If this is the case, then drain the oil from the bearing frame to the level indicat-
ed on the sight gauge.
b) When the oil used to protect the bearing frame is used to run the pump on startup, change this
oil initially at half the recommended time for oil changes.
7. Prepare the grease-lubricated bearing frame:
2.3 Storage guidelines
Model 3498 Installation, Operation, and Maintenance Manual 17

• No special methods are required to prepare for startup.
• You can leave the corrosion inhibitor oil in the frame.
• If the pump is started with the factory-supplied grease, then re-grease initially at half the rec-
ommended grease interval.
8. Remove the tape from the breather and seals.
