Safety
WARNING:
• The operator must be aware of the pumpage and take appropriate safety precautions
to prevent physical injury.
• Risk of serious injury or death. If any pressure-containing device is over-pressurized, it
can explode, rupture, or discharge its contents. It is critical to take all necessary
measures to avoid over-pressurization.
• Risk of death, serious personal injury, and property damage. Installing, operating, or
maintaining the unit using any method not prescribed in this manual is prohibited.
Prohibited methods include any modification to the equipment or use of parts not
provided by ITT. If there is any uncertainty regarding the appropriate use of the
equipment, please contact an ITT representative before proceeding.
• Risk of serious personal injury. Applying heat to impellers, propellers, or their retaining
devices can cause trapped liquid to rapidly expand and result in a violent explosion.
This manual clearly identifies accepted methods for disassembling units. These
methods must be adhered to. Never apply heat to aid in their removal unless explicitly
stated in this manual.
• 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
injury 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 manual.

Storage guidelines
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 recommen-
dations of the respective manufacturers.
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:

Transportation and Storage
Model 3498 Installation, Operation, and Maintenance Manual12
• 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 retard oxidation or corrosion, and to prevent possible brinelling.
• Coat the shaft extensions and other exposed machine surfaces with an easily
removable rust preventative, such as Tectyl No. 502C from Valvoline Oil Company,
Division of Ashland Petroleum Company.
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:
Pumps are shipped from the factory with the bearings pre-greased and require no
further lubrication.
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 preventative 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.

Transportation and Storage
Model 3498 Installation, Operation, and Maintenance Manual 13
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 materials 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.
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 piping.
• The interior of the pump and the piping must be thoroughly dried.

Transportation and Storage
Model 3498 Installation, Operation, and Maintenance Manual14
• Repeat the storage preparation procedure every 12 months.
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 Packing (page 30).
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
Lubricating-oil requirements (page 41) 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 indicated 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:
• 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 recommended grease interval.
8. Remove the tape from the breather and seals.
