User safety is a major focus in the design of our products. Following the precautions outlined in this
manual will minimize your risk of injury.
ITT Goulds pumps will provide safe, trouble-free service when properly installed, maintained, and
operated.
Safe installation, operation, and maintenance of ITT Goulds Pumps equipment are an essential end user
responsibility. This Pump Safety Manual identifies specific safety risks that must be considered at all
times during product life. Understanding and adhering to these safety warnings is mandatory to ensure
personnel, property, and/or the environment will not be harmed. Adherence to these warnings alone,
however, is not sufficient — it is anticipated that the end user will also comply with industry and corporate
safety standards. Identifying and eliminating unsafe installation, operating and maintenance practices is
the responsibility of all individuals involved in the installation, operation, and maintenance of industrial
equipment.
Please take the time to review and understand the safe installation, operation, and maintenance guidelines
outlined in this Pump Safety Manual and the Instruction, Operation, and Maintenance (IOM) manual.
Current manuals are available at
your nearest Goulds Pumps sales representative.
www.gouldspumps.com/literature_ioms.html or by contacting

SAFETY WARNINGS
Specific to pumping equipment, significant risks bear reinforcement above and beyond normal safety precautions.
WARNING
A pump is a pressure vessel with rotating parts that can be hazardous. Any pressure vessel can explode,
rupture, or discharge its contents if sufficiently over pressurized causing death, personal injury, property
damage, and/or damage to the environment. All necessary measures must be taken to ensure over
pressurization does not occur.
WARNING
Operation of any pumping system with a blocked suction and discharge must be avoided in all cases.
Operation, even for a brief period under these conditions, can cause superheating of enclosed pumpage and
result in a violent explosion. All necessary measures must be taken by the end user to ensure this condition is
avoided.
WARNING
The pump may handle hazardous and/or toxic fluids. Care must be taken to identify the contents of the pump
and eliminate the possibility of exposure, particularly if hazardous and/or toxic. Potential hazards include, but
are not limited to, high temperature, flammable, acidic, caustic, explosive, and other risks.
WARNING
Pumping equipment Instruction, Operation, and Maintenance manuals clearly identify accepted methods for
disassembling pumping units. These methods must be adhered to. Specifically, applying heat to impellers
and/or impeller retaining devices to aid in their removal is strictly forbidden. Trapped liquid can rapidly
expand and result in a violent explosion and injury.
ITT Goulds Pumps will not accept responsibility for physical injury, damage, or delays caused by a failure to
observe the instructions for installation, operation, and maintenance contained in this Pump Safety Manual or the
current IOM available at www.gouldspumps.com/literature.

Ensure all fasteners are properly tightened and there are no missing fasteners.
Startup and Operation:
When installing in a potentially explosive environment, please ensure that the
motor is properly certified.
Operating pump in reverse rotation may result in contact of metal parts, heat
generation, and breach of containment.
Lock out driver power to prevent accidental start-up and physical injury.
The impeller clearance setting procedure 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.
If using a cartridge mechanical seal, the centering clips must be installed and set
screws loosened prior to setting impeller clearance. Failure to do so could result
in sparks, heat generation, and mechanical seal damage.
The coupling used in an ATEX classified environment must be properly certified
and must be constructed from a non-sparking material.
Never operate a pump without coupling guard properly installed. Personal injury
will occur if pump is run without coupling guard.
Make sure to properly lubricate the bearings. Failure to do so may result in excess
heat generation, sparks, and / or premature failure.
The mechanical seal used in an ATEX classified environment must be properly
certified. Prior to start up, ensure all points of potential leakage of process fluid to
the work environment are closed.
Never operate the pump without liquid supplied to mechanical seal. Running a
mechanical seal dry, even for a few seconds, can cause seal damage and must be
avoided. Physical injury can occur if mechanical seal fails.
Never attempt to replace packing until the driver is properly locked out and the
coupling spacer is removed.
WARNING
WARNING
Dynamic seals are not allowed in an ATEX classified environment.
DO NOT operate pump below minimum rated flows or with suction and/or
discharge valve closed. These conditions may create an explosive hazard due to
vaporization of pumpage and can quickly lead to pump failure and physical injury.

Shutdown, Disassembly, and Reassembly:
Pump components can be heavy. Proper methods of lifting must be employed to
avoid physical injury and/or equipment damage. Steel toed shoes must be worn at
all times.
The pump may handle hazardous and/or toxic fluids. Observe proper
decontamination procedures. Proper personal protective equipment should be
worn. Precautions must be taken to prevent physical injury. Pumpage must be
handled and disposed of in conformance with applicable environmental
regulations.
Operator must be aware of pumpage and safety precautions to prevent physical
injury.
Lock out driver power to prevent accidental startup and physical injury.
Allow all system and pump components to cool before handling them to prevent
physical injury.
If pump is a Model NM3171, NM3196, 3198, 3298, V3298, SP3298, 4150, 4550,
or 3107, there may be a risk of static electric discharge from plastic parts that are
not properly grounded. If pumped fluid is non-conductive, pump should be
drained and flushed with a conductive fluid under conditions that will not allow
for a spark to be released to the atmosphere.
Never apply heat to remove an impeller. The use of heat may cause an explosion
due to trapped fluid, resulting in severe physical injury and property damage.
Wear heavy work gloves when handling impellers as sharp edges may cause
physical injury.
Wear insulated gloves when using a bearing heater. Bearings will get hot and can
cause physical injury.

Alignment
Alignment procedures must be followed to
prevent unintended contact of rotating
parts. Follow coupling manufacturer’s
coupling installation and operation
procedures.
SET UP
1.Mount two dial indicators on one of the coupling
halves (X) so they contact the other coupling half
(Y) (Fig. III-1).
2.Check setting of indicators by rotating coupling
half X to ensure indicators stay in contact with
coupling half Y but do not bottom out. Adjust
indicators accordingly.
ANGULAR ALIGNMENT
A unit is in angular alignment when indicator A
(Angular indicator) does not vary by more that .002 in.
(.05 mm) as measured at four points 90° apart.
Vertical Correction (Top-to-Bottom)
1.Zero indicator A at top dead center (12 o’clock) of
coupling half Y.
2.Rotate indicators to bottom dead center
(6 o’clock). Observe needle and record reading.
3.Negative Reading - The coupling halves are
further apart at the bottom than at the top. Correct
by either raising the driver feet at the shaft end
(add shims) or lowering the driver feet at the other
end (remove shims), (Fig. III-2).
Positive Reading - The coupling halves are
closer at the bottom than at the top. Correct by
either lowering the driver feet at the shaft end
(remove shims) or raising the driver feet at the
other end (add shims).

APPENDIX IV
Old JM Clipper CFT Design Labyrinth Seal Installation Instructions
Description of Operation
The labyrinth oil seal serves two functions. The first
being to exclude environmental contamination from
the power-end. This is accomplished with a series of
tight clearance fits between the stationary and rotor.
Any water that manages to enter the seal is
eliminated from the seal through a drain slot located
at the six o’clock position when installed.
On the oil side, a series of oil grooves are present to direct
any oil between the shaft and stationary back into the oil
sump through a drain slot at the six o’clock position.
®
O-rings are supplied as standard due to their
Viton
chemical resistance. The stationary uses an O-ring to fit
the labyrinth seal to the housing. The stator uses an
O-ring to fit the labyrinth to the housing. The rotor uses an
O-ring to seal along the shaft and to serve as the drive.
Installation Procedures
l
!
The ITT Goulds labyrinth oil seal is a one piece
assembly. Do not attempt to separate the rotor
and stator. Damage to the seal may result.
1.Assemble the power end per the instructions in
Section 6 - Disassembly & Reassembly.
l
!
The edges of the keyway can be sharp. Failure
to cover the keyway may result in a cut O-ring
and a damaged seal.
2.Wrap tape around the coupling end of the shaft to
cover the keyway.
CAUTION
CAUTION
3.Press the seal over the shaft into the thrust
bearing housing or thrust bearing end cover by
hand until the shoulder of the seal is seated
against the housing/cover.
NOTE: An O-ring lubricant is not required, but
can be used if desired. If used, be sure the
lubricant is compatible with the O-ring material
and plant standards.
4.For STX units: Press the seal over the shaft into
the bearing frame by hand until the shoulder of
the seal is seated against the frame.
For all other units: Once the frame adapter is
installed on the bearing frame, press the seal over
the shaft into the frame adapter by hand until the
shoulder of the seal is seated against the adapter.
NOTE: An O-ring lubricant is not required, but
can be used if desired. If used, be sure the
lubricant is compatible with the O-ring material
and plant standards.
NOTE: During start-up when the parts of the
labyrinth oil seal establish a voluntary running
clearance, a small amount of wear is experienced
as the parts are in contact. This wear produces a
carbon filled Teflon
diameter of the seal and at the drain slot. This is
the result of the two surfaces being smoothed,
similar to burnishing. A lubricant should not be
applied between the faces at installation. Once the
running clearance has been established, no further
wear is experienced and no decrease in seal
performance occurs as a result of the carbon/
®
Teflon
residue.

NOTE: The smooth surface of electrical tape
provides an excellent surface to slide the rotor
O-ring over.

l
The motor may be heavy and should be
properly supported with a clean, uncorroded
eye bolt or a strap under both end bells.
NOTE: Use of a C-Face adapter will result in
one of the following configurations — a foot
mounted adapter with an overhung motor or an
unsupported adapter and a foot mounted motor.
2.Remove the C-Face adapter (340) from the pump
bearing frame (228A) by loosening the four bolts
(371N) attached to the bearing frame flange.
NOTE: Both coupling hubs do not need to be
removed.
CAUTION
Inspections
1.Visually inspect the C-face adapter (340) for
cracks. Check surfaces for rust, scale, or debris.
Remove all loose or foreign material (Fig. V-1).
2.Check for corrosion or pitting.
Reassembly
1.Mount both the pump and motor coupling hubs if
not already mounted.
2.Slide the C-Face adapter (340) over the pump
shaft (122) and mount against the pump bearing
frame (228A) flange using four bolts (371N).
Torque bolts to the values shown in Table V-2.
3.Mount the motor to the C-Face adapter (340)
using the four or eight motor bolts (371). Torque
bolts to the values shown in Table V-2.
A shaft alignment is not required when using the C-Face
adapter. The rabbetted fits of the motor to the adapter
and the adapter to the bearing frame automatically
aligns the shaft to within the specified limits below.
The C-face motor adapter is intended for end users
who need fast pump installation. A C-face adapter
can attain a nominal alignment of 0.007 inches TIR.
However, due to the stack up of machining tolerances
of the various parts, the alignment can be as high as
0.015 inches TIR. Using a flexible, elastomer
coupling like a Rexnord ES or Wood's Sureflex will
provide acceptable pump and motor life under these
alignment conditions.
To achieve the best Mean Time Between Pump
Maintenance (MTBPM) requires shaft alignments of
less than 0.002 inches (0.05mm). End users who
require high pump and motor reliability are better
served by using a foot mounted motor on a precision
machined baseplate and performing a conventional
alignment.

Do not heat the sleeve with an open flame.
Irreparable damage will occur to the sleeve.
For those users who do not have the above facilities,
shaft/sleeve sub-assemblies are available from ITT
Goulds.
1.Remove the old or damaged sleeve (126) from
the shaft (122). The sleeve may be cut
lengthwise with a sharp knife.
2.Thoroughly clean the shaft. Pay particular
attention to the knurled area of the shaft under the
sleeve.
NOTE: The replacement sleeve will not have
the same dimensions as the sleeve which was
removed until it is mounted on the shaft and
machined.
3.Heat the replacement sleeve in a controlled oven
at 550° F (288° C) for 40 minutes.
l
!
Do not heat the sleeve with an open flame —
irreparable damage will occur to the sleeve.
!WARNING
s
The oven and sleeve are hot. Use insulated gloves
to prevent burn injuries.
4.Remove the sleeve from the oven.
5.Slide the sleeve onto the shaft immediately after
removing it from the oven. Push the sleeve onto
the shaft until the sleeve bottoms out on the
shoulder of the shaft (Fig. VI-1). The hook end of
the sleeve will extend beyond the knurled portion
of the shaft.
CAUTION
CAUTION
6.As the sleeve cools, it will shrink in length. Apply
light pressure to keep the sleeve against the shaft
shoulder. Maintain pressure until the hook
portion of the sleeve seats itself against the
shoulder under the hook (Fig. V-2).

1.Inspect the shaft (122) to ensure that it is clean,
dimensionally correct, and is free of nicks, burrs,
etc.
2.Lightly coat the bearing seating with a thin film of
oil.
3.Remove the bearing (112) from its packaging.
4.Wipe the preservative from the bearing (112) bore
and outer diameter.
5.Use an induction heater with a demagnetizing
cycle to heat bearing (112) to an inner ring
temperature of 230 °F (110 °C).
!WARNING
s
Wear insulated gloves when using a bearing
heater. Bearings will get hot and can cause
physical injury.
6.Position the bearing (112) on the shaft (122)
against the shoulder and snug the locknut (136)
against the bearing until it is cool. The locknut
prevents the bearing from moving away from the
shaft shoulder as it cools.
NOTE: Regreasable bearing has a single shield.
The outboard bearing is installed with shield
toward impeller.
7.Remove bearing locknut (136) after bearing (112)
has cooled.
8.Place lockwasher (382) on shaft (122). Place
tang of lockwasher in keyway of shaft.
9.Thread locknut (136) onto shaft (122). Tighten
locknut one-eighth (1/8) to one-quarter (1/4) turn
beyond snug. Bend any tang of lockwasher (382)
into a slot of locknut.
NOTE: Tighten locknut if necessary to align the
closest tab of lockwasher with slot on locknut,
but do not overtighten. See Table VII-1 for
maximum locknut torque.

APPENDIX VIII
INPRO Labyrinth Oil Seal Installation Instructions
Description of Operation
The INRP VBXX-D®Labyrinth Oil Seal is specially
designed to protect pump bearings from lubrication
starvation as well as environmental contamination.
The bearing is made up of three basic parts: the rotor
(1), stator (2), and VBX
over the shaft and is held in place by an elastomeric
drive ring (4). The drive ring causes the rotor to turn
with the shaft and provides a positive, static seal
against the shaft. There is no metal-to-metal contact,
therefore, no friction or wear concerns.
®
Ring (3). The rotor (1) fits
Intallation Procedures
!CAUTION
l
The INPRO VBX is a one piece design. Do not
attempt to separate the rotor (1) from the stator
(2) prior to or during installation.
1. Assemble the power end per the instructions in
Section 6 - Disassembly and Reassembly.
l
!CAUTION
The edges of the keyway can be sharp. Failure
to cover the keyway with tape may result in a
cut o-ring and a damaged seal.
2.Wrap some electrical tape around the coupling
end of the shaft to cover the keyway.
NOTE: The smooth surface of the electrical
tape provides an excellent surface to slide the
rotor O-ring over.
3. Lightly lube the shaft and rotor drive ring (4) with
supplied lubricant.
NOTE: Lubricant will aid in the installation
process. If used, be sure the lubricant is
compatible with the O-ring material and plant
standards.
4. Use an arbor press to install the outboard INPRO
VBXX-D
port (6) at the 6 o'clock position. Press it only as far
as the beginning of the stator location ramp (9) and
avoid angular misalignment. There is nominal 0.002"
interference fit. Discard any residual material from
the stator gasket (5).
For STX Units
5. Press the inboard seal over the shaft into the
bearing frame as described in Step 4 above.
For All Other Units
5. Once the frame adapter is installed on the
bearing frame, press the inboard seal over the shaft
and into the adapter as descbied in Step 4 above.
