protects its products for shipment. However, the
effective life of the preservatives applied at the factory
can vary from 3 to 18 months depending on the severity
of the environment in which the equipment is stored.
This section provides procedures for preparation prior to
storage and maintenance during storage of Goulds Water
Technology pumps. These procedures are necessary
to protect the precision parts of the pumps. Specific
procedures for storing motors, gear-drivers, and engines,
should be obtained from the equipment manufacturer.
This section is intended to be of general assistance to
users of Goulds Water Technology VIC pumps. It shall
not modify, amend and/or otherwise alter the scope
of Goulds Water Technology VIC pumps warranty
responsibilities to the purchaser in any way whatsoever.
Storage Preparation
Goulds Water Technology VIC pumps require proper
preparation for storage and, regular maintenance during
storage. The pump shall be considered in storage when
it has been delivered to the job site and is awaiting
installation.
Preferably, the storage area shall be paved, well drained
and free from flooding, and be indoors whenever
possible.
Weatherproof coverings used for outdoor storage shall be
flame resistant type sheeting or tarpaulins. They shall be
placed so as to provide good drainage and air circulation
and shall be tied down to protect from wind damage.
Storage area shall be maintained in a clean condition at
all times.
Pumps and/or component parts shall be placed on skids,
pallets, or shoring to permit good air circulation.
Pumps and/or component parts shall be sorted so as to
permit ready access for inspection and/or maintenance
without excessive handling.
Pumps and/or component parts stacked during storage
shall be arranged so that the racks, containers, or crates
bear full weight without distortion of pumps or parts.
Identification markings must be readily visible. Any
cover removed for internal access shall be replaced
immediately.
Pump and bowl assembly shafting shall be rotated
counter clockwise, as a minimum, once a month. Shaft
shall not be left in the same previous position, nor in the
extreme raised or lowered lateral position. Shaft should
rotate freely.
NOTE: For further information on these procedures
contact your Goulds Water Technology
representative.
Recommended Storage Procedures
Controlled storage facilities should be maintained at an
even temperature 10º F (6º C) or more above the dew
point with relative humidity less than 50% and little or
no dust. (If these requirements can not be met the pump
is to be considered in uncontrolled storage.)
For uncontrolled storage periods of 6 months or less,
the pump is to be inspected periodically to insure that all
preservatives are intact.
All pipe threads and flanged pipe covers are to be sealed
with tape.
The pump must not be stored closer than six inches (15
cm) from the ground.
5
Uncontrolled Long Term Storage Preparations
When applicable to the pump, storage periods over six
months require the preceding storage procedure and
storage preparation plus the following:
Inspect the lube oil and seal flush piping and either
fill the piping with rust preventative oil, or re-coat the
piping periodically to prevent corrosion.
Place 10 pounds (4.5 kg) of moisture absorbing desiccant
or 5 pounds (2.3 kg) of vapor phase inhibitor crystals
near the center of the pump. If the pump is assembled,
place an additional one pound (0.5 kg) in the discharge
nozzle securely fastened to the discharge elbow.
Install a moisture indicator near the perimeter of the
pump. Cover the pump with 6 mil (0.15 mm) minimum
thickness black polyethylene or equal and seal it with
tape. Provide a small ventilation hole approximately ½
inch (12 mm) diameter.
Discharge Head
The discharge head is either a cast iron head or a
fabricated head. Ports are provided for connecting
the pressure gauge, stuffing box or mechanical seal
bypass return and lubricator connections. The driver
support portion of the discharge head is designed with
large windows for easy stuffing box or mechanical seal
adjustment. The windows are covered with coupling
guards for safe operation.
Column
Threaded or flanged column construction provides
positive shaft and bearing alignment and ease of assembly
and disassembly. The line-shaft is supported within
the column by using bearing retainers in the column
assembly. The retainers are usually integrally fabricated
in the column pipes. Bearings are spaced to provide
vibration free operation below the shaft first critical
speed in order to insure long bearing life and reduced
shaft wear.
Provide a roof or shed shelter to protect from direct
exposure to the elements.
GENERAL DESCRIPTION
The model VIC pump is a vertical industrial turbine type
pump installed in a can (barrel), and is designed to meet
wide ranges of service with maximum dependability. See
Figure 1 or Figure 2 for some typical VIC pump.
Drivers
When mechanical seals are required, the most common
type of drivers supplied are solid vertical shaft motors
with adjustable spacer type couplings. When packed
stuffing boxes are used with open line shaft pumps,
hollow shaft motors or right angle gear drives, are often
used with a separate head shaft through the driver and
connected to the pump by a threaded coupling.
Bowl Assembly
The bowls are generally of flanged construction for
accurate alignment and ease of assembly and disassembly.
Impellers may be either open or enclosed depending
on the design requirements. They are fastened to the
pump shaft by taperlocks. For temperatures over 140°F
(60°C) and in the larger size bowls (over 18”), impellers
are keyed to the shaft. A special first stage low NPSH
impeller may be provided in certain application.
Thrust Pot
A thrust pot is utilized when the driver is not designed to
carry the pump thrust.

When pumping unit is installed in a potentially
explosive environment, the instruction after
the 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 equipment is to be
modified, please contact a Goulds Water Technology
representative before proceeding.
FOUNDATION AND PIPING
SUB BASE (SOLE PLATE) OR BARREL FLANGE
INSPECTION
Sub base and sole plate are terms in common use to
describe a general class of solid steel plates mounted
in grout (or bolted to steel structures) at the pumpfoundation interface.
1. Remove the sub base from the pump discharge head
or barrel flange, when shipped assembled.
2. Completely clean the underside of the sub base. It is
sometimes necessary to coat the underside of the sub
base with an epoxy primer. (This is available as an
option.)
3. Remove the rust preventative solution from the
machined topside with an appropriate solution.
SITE WITH CONCRETE FOUNDATION
1. A pump should have adequate space for operation,
maintenance, and inspection.
2. Sub base mounted pumps are normally grouted
on a concrete foundation, which has been poured
on a solid footing. The foundation must be able to
absorb any vibration and to form a permanent, rigid
support for the pumping unit.
3. The foundation must be of adequate strength to
support the complete weight of the pump, plus the
weight of the liquid passing through it. A typical
installation will have bolts with a pipe sleeve 2 ½
times the bolt diameter embedded in the concrete.
Bolts should be sized and located in accordance
with the dimensions given on the Certified Pump
Outline Drawing, if provided. The pipe sleeve
allows movement for the final positioning of the
foundation bolts to conform to the holes in the sub
base flange. See Figure 3.
All equipment being installed must be properly
grounded to prevent unexpected static electrical
discharge. If not, a static electric discharge may
occur when the pump is drained and disassembled for
maintenance purpose.
4. Remove water and/or debris from anchor bolt holes/
sleeves prior to grouting. If the sleeve type bolts are
being used, fill the sleeves with packing or rags to
prevent grout from entering.
5. Carefully lower the sub base onto the foundation
bolts. Hand tighten the nuts.
6. Leveling the sub base may be done by several
methods. Two common methods are:
A. Using leveling wedges. This is shown in Figure 4.
B. Leveling nuts on the anchor bolts.
Regardless of the method, a machinist level must be
used for leveling.
NOTE: When using a machinist level, it is important
that the surface being leveled is free of all
contaminants, such as dust, to ensure an
accurate reading.
7. Level the sub base in two directions at 90º on the
machined surface. The levelness tolerance is 0.005
inches per foot for commercial, and 0.001 inches
per foot for API.

concrete foundation, up to level of dam. Remove
air bubbles from grout as it is poured by puddling,
using a vibrator, or pumping the grout into place.
Non-shrink grout is recommended.
4. Allow grout to set at least 48 hours.
5. Tighten foundation bolts.
SITE WITH STRUCTURAL STEEL FOUNDATION
When the pump is mounted directly on a structural steel
frame, pumps shall be located directly over, or as near as
possible to, the main building members, beams or walls.
The barrel, discharge head mounting flange or sub base,
shall be bolted to the support to avoid distortion, prevent
vibration and retain proper alignment.
PUMP INSTALLATION
When pumping unit is installed in a potentially
explosive environment, the instruction after the
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 equipment is to be modified, please
contact a Goulds Water Technology representative before
proceeding.
Pumps of 20 feet (6 m) or less in length are usually
shipped assembled, with the exception of the driver,
mechanical seal with tubing and coupling assembly,
spacer or non spacer type. When provided, refer to the
Certified Pump Outline for the applicable base plate plan
for the location of anchor bolt holes.
INSTALLING A PARTIALLY ASSEMBLED PUMP
PIPING
Guidelines for piping are given in the “Hydraulic
Institute Standards”, available from: Hydraulic Institute,
9 Sylvan Way, Parsippany, NJ 07054-3802 and must be
reviewed prior to pump installation.
Never draw piping into place by forcing
the flange connections of the pump. Pipe
strain will adversely effect the operation of the pump
resulting in damage to the equipment and possible
physical injury.
1. All piping must be supported independently, and
line up naturally with the pump flange so that undue
pipe strain is not imposed on the pump.
2. DO NOT connect piping to pump until grout has
hardened and pump hold-down bolts have been
tightened.
3. It is suggested that expansion loops or joints, if used,
be properly installed in the discharge line. When
handling liquids at elevated temperatures expansion
joints are used, so linear expansion of piping will
not draw pumps out of alignment.
4. Carefully clean all pipe parts, valves and fittings,
and piping branches prior to assembly.
5. Isolation and check valves should be installed in
discharge line. Locate the check valve between
isolation valve and pump, this will permit inspection
of the check valve. The isolation valve is required
for regulation of flow, and for inspection and
maintenance of pump. The check valve prevents
pump or seal damage due to reverse flow through
the pump when the driver is turned off.
6. Increasers, if used, should be placed between pump
and check valves.
1. If a base plate was supplied, install as described in
Foundation/Piping Section (page 9).
2. Clean the mounting surface of the plate and clean
bottom surface of discharge head mounting flange.
3. Check that all fasteners on the pump are tight, as it
is recognized that transportation and handling may
result in bolt relaxation.
4. Install the barrel (can) to discharge head O-ring
(743).
5. Sling through discharge head holes or thread two
eyebolts through bolt holes in mounting flange and
hoist unit into position over foundation.
NOTE: Eyebolts or sling should be rated to handle
in excess of the pump weight (see Outline
Drawing).
6. Lower the unit and carefully guide it so that unit
does not strike the side of the base plate. Continue
to lower unit until the discharge head flange engages
and rests firmly on the plate, then secure with
capscrews provided.
7. When a lineshaft is shipped separately check shaft
for straightness; average total run out should not
exceed 0.005” T.I.R. (0.127mm) for 10 feet (3 m).
Shaft must be within tolerance prior to installation.
8. Refer to remainder of this manual for complete
assembly, startup, maintenance, disassembly and
recommended lubricants for the pump.
INSTALLING THE BOWL ASSEMBLY
Do not work under a heavy suspended
object unless there is positive support and
safe guards, which will protect personnel, should a hoist
or sling fail.
7. Cushioning devices should be used to protect the
pump from surges and water hammer if quickclosing valves are installed in the system.
10
Do not attempt to lift bowl assembly
by the pump shaft. This can result in
damaging the pump shaft.
1. Prior to installing the bowl assembly, check that
CAUTION
CAUTION
CAUTION
all capscrews are tight. Turn the pump shaft by
hand and make sure it turns freely. Remove all
accumulated dust, oil, or other foreign material
from the external surfaces.
2. If a suction strainer is provided, assemble it to the
suction bell (or suction bowl).
1. Coat a thin film of oil to the threads on the lineshaft
(646) and the coupling (649) (for non-galling
material, or Molykote if galling material).
2. Install threaded coupling onto pumpshaft by
threading it on for one-half its length. A fine
wire inserted in the drill hole at the center of the
coupling can be used as a gauge to determine
when the coupling is correctly positioned on the
pumpshaft. Remove the wire after installed the
coupling.
Use “MOLYKOTE” Dow Corning or
equal for all galling material such as 316
stainless steel.
INSTALLING THE COLUMN
OPEN LINESHAFT
Pump lineshafts are coupled with either threaded
or keyed couplings. Follow only those procedures
appropriate for the type of lineshaft coupling supplied.
When provided, see the Certified Pump Outline Drawing
for the number of column and shaft sections required.
Figure 5
3. Place two I-beam supports across the base plate
opening, strong enough to safely support the weight
of the entire pump assembly. These I-beams should
be connected by threaded rods and nuts so as to
clamp them firmly together for the portion to be
supported. (See Figure 5).
4. Place a suitable hoist or derrick over base plate
opening with the hook in the center. Place the
elevator clamps just below the discharge bowl. Place
the elevator clamps just below the discharge bowl.
For flanged column install two threaded eyebolts
through the discharge bowl bolt holes 180º apart
for flanged column. For threaded discharge utilize
a lifting bail sized to handle the weight of the bowl
assembly and suction apparatus. Attach a sling to the
elevator clamps, eyebolts, or lifting bail and hoist it
into position.
5. Carefully lower bowl assembly, guiding the unit so it
does not strike the sides of the opening. Continue
to lower bowl assembly until the elevator clamps
or discharge bowl flange rests firmly on the I-beam
supports.
6. Place a cover over the discharge bowl opening to
prevent entrance of dirt or other foreign matter
until ready for installation of the column assembly.
Do not drop any foreign object into the
bowl assembly. Such an object can cause
serious damage to the pump and any downstream
components. Any foreign object dropped into the bowl
assembly must be retrieved prior to continuing assembly.
THREADED COUPLING INSTALLATION
NOTE: Shaft threads are left-handed.
When the threaded coupling is not installed on the
pumpshaft, install as follows:
1. Check the headshaft (608) and lineshaft (646) for
straightness. Average total runout should be less
than 0.0005” T.I.R. per foot, not to exceed 0.005”
T.I.R. for every 10 feet of shafting.
2. Hoist the first piece of lineshaft over the bowl
assembly. Lower the lineshaft until the bottom end
is properly aligned with the coupling of the pump
shaft. Apply a thin film of oil to the threads on the
lineshaft (646) and the coupling (649) (for nongalling material, or Molykote if galling material).
Use “MOLYKOTE” Dow Corning or
equal for all galling material such as
316 stainless steel.
3a. With lineshaft in the proper position on the
coupling, screw lineshaft into the coupling manually
until resistance is felt. A fine wire inserted in the
hole at the center of the coupling can be used as a
gage to determine when the coupling is correctly
positioned on the shaft. Remove the wire after installing the shaft. Completely tighten the joint
by using a pair of pipe wrenches. Use care not to
damage any bearing journal areas on the shaft.
NOTE: Shaft threads are left-handed.
3b. With a keyed coupling
insert the key into the
pump shaft. Lower the
sleeve over the pump shaft,
to approximately 1.0 in
(25.4 mm) below the top
of the shaft. Then lower
the lineshaft until it touches
the pump shaft. Insert the
split ring into the grooves
of the pump shaft and
lineshaft. Raise the sleeve
until it covers the split ring,
then insert the key into the
lineshaft. Raise the sleeve to the top of the key and
secure the sleeve to the split ring with a lock screw
and lock wire.
11
CAUTION
WARNING
CAUTION
4. Install two eyebolts diametrically opposite the upper
flange of the bottom column (644). Attach a sling to
the eyebolts and to the hoist hook. Lower column
section until the flange engages the flanged top bowl
register. Insert as many bolts through both flanges
as possible. Lift column assembly high enough to
allow rotation of the supports. Install and tighten
remaining capscrews gradually in diametrically
opposite pairs until all are uniformly tightened.
5. Lift the assembly and remove the elevator clamp or
supports and slowly lower the bowl and the column
assembly. Place supports on the base plate and
continue to lower the assembly until the column
elevator clamps or column flange comes to rest on
the supports.
NOTE: Normally, the bearing retainer will be integral
with column. The top flange of the column will
have male register and the bottom flange of the
column will have a female register. If you have
separate bearing retainers, there will be a female
register in the flange at both ends of the column.
Follow step 6 below.
6. Place the bearing retainer (652) with bearing (656)
over the shaft and fit the retainer in the female
register of the flange. Make sure the contact faces in
the flanges are clean. Use a file to remove nicks or
dings.
7. Install threaded coupling (649) on the protruding
end of the lineshaft (646), if required.
8. Assemble next column (642) section, or top column
(641) as required, and make sure bottom column
register (or bearing retainer (652)) engages the top
column register, and secure with capscrews (760B)
and hex nuts (735A) provided. Tighten capscrews
into hex nuts gradually and uniformly.
9. Repeat the preceding procedures until all column
sections required have been installed.
Do not drop any foreign object into the
column assembly. Such an object can
cause serious damage to the pump and any downstream
components. Any foreign object dropped into the column
assembly must be retrieved prior to continuing assembly.
INSTALLING THE DISCHARGE HEAD
VIC Pumps are provided with either “T” type or “L” type
head. Install the discharge head as follows:
1. If the stuffing box (See Fig. 6) is assembled to the
head, remove it and all the attached piping.
2. When a mechanical seal is provided it is shipped
separately.
3. Remove coupling guard if provided. Attach a sling
to the lifting lugs on the side of the discharge head
or through windows and hoist discharge head over
the protruding top shaft.
Eyebolts or sling should be rated to handle
in excess of the pump weight (see Outline
Drawing).
Do not bump or scrape the shaft protruding above the column. This could result in
bending or damaging the shaft.
12
4. Orient the discharge head in the required position
and lower the head. Centering the vertical hole with
the top shaft protruding above the column until the
discharge head engages the column flange. Install
capscrews and secure discharge head to the column
flange. Tighten capscrews gradually in diametrically
opposite pairs.
5. Lift the pump assembly high enough to allow rotation of the supports. Realign and lower assembly.
Install and tighten remaining capscrews. Repeat
the rotating and the tightening procedure until all
capscrews are uniformly tight.
6. Hoist the discharge head by lifting lug and remove
the elevator clamp attached to column.
7. Remove the support timbers or I-beams and clean
the top of barrel flange. Orient the discharge head
in the required position.
NOTE: Sling should be rated to handle in excess of the
pump weight.
8. Lower bowl, column and head assembly, until
discharge head mounting flange engages with the
barrel flange. Secure discharge head to barrel.
Check the levelness of the discharge head in all
directions, utilizing a machinist level across the
driver’s mounting surface of the discharge head.
9. Check whether the top shaft (or stub shaft) is in
the center of the stuffing box bore. If not, the shaft
must be centered by shimming the head base and the
sub base (or the foundation).
10. Rotate the shaft approximately 90º. Check again
whether the shaft is at the center of the stuffing box
bore or not. If not, either the top shaft is bent or the
first shaft below it did not butt properly. Correction
must be made before the installation procedures can
proceed.
INSTALLING THE STUFFING BOX
Assemble stuffing box as shown in Figure 6.
1. Clean the surface of the discharge head where
the stuffing box will be mounted and remove any
nicks or burrs with a fine flat file. Position gasket
on surface. Slide stuffing box (616) down over
headshaft and into position on the gasket. Secure
stuffing box with capscrews.
2. Grease the packing ring (620) for easier installation.
3. Twist the packing ring sideways to get it around the
shaft easily. Start the first ring into the stuffing box.
When the entire ring is worked in using the fingers,
tamp it down using a split wood bushing (or equal)
and push the packing ring down firmly. It must seal

compression of packing and damage to the shaft or sleeve
and heat up the shaft and stuffing box.
7. The stuffing box is shipped with both ports plugged.
If the discharge pressure is over 100 psi, remove the
plug on Port “A” and attach a bypass (relief) line. If
the discharge pressure is over 200 psi, remove the
plug on Port “B” and attach another bypass line.
8. Final adjustment of the stuffing box must be made at
pump start up.
9. A properly packed stuffing box should be loose
enough to allow the shaft to be turned manually
and must have leakage (see page 22 – Packing Adjustment).
Do not over tighten packing or excessive

protect by covering the inside of the pump seal
housing. Remove burrs, nicks and sharp corners by
using a strip of emery cloth over the shaft threads.
File threads around the keyway with a smooth mill
file or emery cloth. Sharp edges must be rounded.
3. Remove all chips and dust from the shaft area.
4. Check that all rotary unit parts of the seal fit over
the shaft. A pre-check may be made by removing the
O-ring(s) from the cartridge sleeve Inside Diameter
(ID) and then installing the seal on the shaft. Further
shaft clean up will be necessary when the seal will
not pass all the way into the seal housing.
5. Remove the seal after the pre-check, and re-install
the sleeve O-ring(s).
6. Sparingly lubricate the shaft and sleeve ID with
the lubricant included with the mechanical seal or
recommended by the mechanical seal manufacturer.
The following lubricants may be used, for water service, when no lubricant is supplied or recommended
by the mechanical seal manufacturer.
• Light oil (SAE #10 or 20)
• Dow Corning #4 Grease
• Silicone lubricant
• Wax or clay
• Soapy water

INSTALLING THE MECHANICAL SEAL
The vertical turbine pumps are usually supplied with
cartridge type mechanical seals, shipped assembled
- ready for installation, when mechanical seals are
supplied. Instructions for installing mechanical seals
are provided by the seal manufacturer. Consult the seal
manufacturer’s instructions (furnished with the seal) for
information on the type of seal used. Additionally, refer
to factory furnished outline drawing and seal piping
schematic on complex seal piping arrangements.
GENERAL REQUIREMENTS FOR ALL SEALS
1. Check surfaces at the face of the seal housing and
at the bottom of the seal housing to insure that they
are clean, flat and free of burrs. The face surface
must be smooth to form a good sealing surface for a
gasket or O-ring.
2. Check that shaft is smooth, and free of burrs, nicks
and sharp corners that could ruin the O-ring or
Oil based lubricants will damage EPR / EPDM
elastomer O-rings. Silicone lube and soapy water are
safe for EPR / EPDM elastomer O-rings.
7. Install the O-ring or gasket, between the seal
housing and seal. Install the seal over the shaft and
ease it into position against the face of the seal box.
Take care when passing the sleeve and O-ring over
keyways or threads to avoid damaging the O-ring.
Do not bump carbon members against the
shaft as they may chip, crack or break.
8. Position seal gland on discharge head seal housing
and secure with capscrews (or nuts for studs)
provided. Tighten capscrews gradually and
uniformly in a criss-cross pattern, taking 2 or 3
passes.
Do not over tighten capscrews on gland.
This can distort seal seat and cause seal
failure.
9. Install all seal piping as required. Prior to making
final connections of sealing liquid pressurizing
lines, make sure the seal housing and all sealing
liquid lines are flushed free of dirt, scale and other
particles that would be abrasive to the sealing faces.
10. The Driver and Coupling must now be installed
before the driver installation can proceed. See page
14 - INSTALLATION OF A HOLLOW SHAFT
DRIVER or page 16 - INSTALLATION OF A
SOLID SHAFT DRIVER as appropriate.

INSTALLING THE DRIVER
When installed in a potentially explosive
environment, please ensure the motor is
properly certified.
Serious damage may result if pump is run
in the wrong direction.
NOTE: When pump is supplied with a thrust pot, do not
secure the driver to discharge head until after the
thrust pot and flexible coupling are installed.
INSTALLATION OF A HOLLOW SHAFT DRIVER
This refers to either VHS type electric motors or hollow
shaft type gear drives. A small paragraph will be devoted
to combination electric motor and right angle gear
drives.
Do not work under a heavy suspended

WARNING
object unless there is a positive support
and safe guards which will protect personnel should a
hoist or sling fail.
1. The driving mechanism of all hollow shaft driver is
shown on Figure 7. The head shaft (608) extends up
through the quill or hollow shaft of the driver and
is held in place by an adjusting nut (604), which not
only carries all the static and hydraulic thrust of the
impellers and shaft, but also provides the adjustment
for the impeller clearances. The head shaft is
connected to top shaft (or stub shaft) by a threaded
coupling or a rigid flange coupling.
2. Attach a sling to the lifting lugs of driver and hoist
the driver up. Inspect the mounting surface, register
and clean these surfaces thoroughly. If any burrs
are found, remove burrs with a smooth mill file,
cleaning thoroughly afterward.
3. For motor, orient the motor conduit box in the
required position. For the right angle gear, orient
the input shaft to the desired position. Align the
driver mounting holes with the mating tapped holes
on the discharge head. Lower the driver until the
registers engage and the driver rests on the discharge
head. Secure driver with capscrews provided.
4. Lubricate the driver bearings in accordance with
instructions given on lubrication plate attached to
the driver case. (Or refer to IOM of the driver)
5. After lowering and orienting the driver as explained
above, remove the drive coupling and the hold
down bolts (See Figure 16). Be sure to mark the
location of the coupling before removing it.

top flange, discharge head base flange to base plate
or the base plate itself could be out of level. If the
latter, shimming between it and discharge head base,
will correct it. Also, check concentricity of motor to
motor-stand (if provided) to discharge head.
9. With the motor in place and the head shaft
projecting through the motor quill shaft, make
temporary electrical connection to check the motor
rotation. (Be sure to remove the ratchet pins or balls before checking motor rotation.) Motor must rotate
counter-clockwise when viewed from the top. See
arrow on pump name plate. If motor does not rotate
counter-clockwise, you can change the rotation by
interchanging any two leads.
Never check motor rotation with the drive
coupling in place. The bore clearance
between the drive coupling and the pump shaft O. D.
is so close that should the motor spin with this shaft
stationary, galling and locking together is very likely to
take place.
10. Install motor drive coupling. (Be sure to line up the
match mark made at step 5.) Insert the ratchet pins
if a non-reverse ratchet is used. Match the coupling
lugs with corresponding holes in motor. Tighten
hold down bolts evenly, making sure driver coupling
is properly seated in the register fit.
11. Fit gib key (730) into keyway, by filing if necessary,
to where there is a snug but sliding fit. This key
must be able to be removed by gentle leverage with
a screwdriver under it.
12. Be careful that the gib key (730) is not too high so
as to hold up the adjusting nut (604) from seating
on the drive coupling. If it is, cut off some length of
the key.
13. Install adjusting nut (604) to hand tight.
COMBINATION ENGINE AND MOTOR DRIVES
1. On combination drivers, the motor is invariably on
top with a projecting head shaft extension.
Figure 7
6. Lower the head shaft through the motor quill shaft
to meet the shaft coupling. Apply a thin film of oil
to head shaft threads (if non-galling material) and
screw into the shaft coupling (located above the
stuffing box). Make sure the shaft is not damaged in
any way. Tighten the joint.
7. Check that the head shaft centers inside the driver
quill shaft within 0.06” (1.5mm). If it does not,
misalignment is indicated.
8. Any head shaft misalignment with driver quill
shaft could be caused by a bent head shaft, burrs,
or foreign matter between shaft ends or any of the
mounting flanges: motor flange to discharge head
2. Follow all procedures outlined in the previous
paragraph, except that the motor must be lowered
over this extended head shaft and great care must be
taken to center it exactly so as not to bump or misalign the shaft while the motor is being lowered into
place.
3. There are several methods of running engines
without electric motors and vice versa, requiring
simple adjustment to the combination drive, but
they are too numerous to mention here and can be
obtained from the gear manufacturers instructions
included with the shipment.

2. Orient the motor conduit box in the required
position. Align the motor mounting holes with the
mating tapped holes on the discharge head. Lower
the motor until the registers engage and the motor
rests on the discharge head. Secure motor with
capscrews provided.

3. On drivers having a nonreverse ratchet or pins,
manually turn the driver shaft clockwise viewed
from the top until the nonreverse ratchet or pins
fully engage.
G
4. Lubricate motor bearings in accordance with
instructions given on lubrication plate attached to
the motor case.
Figure 8
NOTE: 1.00” and 1.18” diameter shafts are 12 thread
per inch (tpi), 1.50" through 2.44" are 10 tpi, all
larger sizes are 8 tpi.
3. For Open Impellers, Align hole “A” in the adjusting
nut (604) and hole “C” in the driver coupling
(See Figure 8) or whatever similar holes are in like
position. If care is exercised, this will give an initial
impeller clearance of 0.001” to 0.003” depending
on shaft size or the pitch of the thread.
4. Insert capscrew into hole “B” provided these are
the nearest matching holes for counter-clockwise
rotation of adjusting nut, turn adjusting nut counterclockwise until holes “B” and “D” line up. This
gives 1/20 of a turn which is 0.004” on 12 tpi shaft
or 0.005” on 10 tpi shaft.
5. Normal impeller clearance for the open impeller is
considered to be 0.015” for the first 10 feet of the
column length and 0.010” additional clearance for
each 10 ft of length thereafter. This can be reduced
in some instances where is necessary, but should
not be attempted without consulting the factory or
factory serviceman is present.
NOTE: Please read and follow the motor manufacturer’s
instructions before lubricating the motor
bearings. Too much lubricant can cause the
bearings to overheat prematurely.
The motor must not be tested for direction
of rotation when coupled to the pump.
If pump should rotate in the wrong direction, serious
damage to the pump and motor would result. Also
serious injury to personnel could result.
5. Make temporary electrical connections according
to tagged leads or diagram attached to the motor.
Motor must rotate counterclockwise when viewed
from the top. See arrow on pump name plate. If
motor does not rotate counterclockwise, you can
change the rotation by interchanging any two leads.
6. Motor shaft end play adjustment: if required,
motor shaft end play shall be checked with a dial
indicator prior to connecting the pump coupling to
the solid shaft motor. Consult the applicable motor
manufacturers instruction manual for detailed
information on motor shaft end play.

7. If the pump is supplied with an adjustable spacer
coupling (see figure 10), install spacer (612) between head shaft and driveshaft hubs. Secure with
capscrews (759) and hex nuts (735).
IMPELLER ADJUSTMENT
Improper impeller adjustment could cause
contact between the rotating and stationary
parts, resulting in a spark and heat generation.

secured to the shaft prior to impeller adjustment.
(open or enclosed type impellers). Shaft must
move up or down within the seal Assembly.
For pumps handling liquids between –50º to
200º F, impeller adjustment can be made under
ambient conditions. For liquids in excess of
this range, it is recommended that impeller
adjustment be made after the pump surface
temperature has reached an equilibrium when
charged with the pumpage. In those cases, where
this is not feasible due to safety consideration
or impossible due to external ice build up in
cryogenic applications, refer to factory for
specific instructions.
OPEN IMPELLERS
1. With the impellers touching the bottom of the
bowls, turn the adjusting plate (613) towards the
driver hub (610) or spacer (612) obtain 0.015 inch
clearance between the adjusting plate and driver
hub or spacer for the first 10 feet of column. Add
0.010” for each additional 10 feet of column. See
figure 10 or 11. Note: The determination of driver
shaft end play can be critical and should be added
to this setting. For larger pumps over 8”, this
amount may be too little; please refer to Outline
Drawing.
Impeller adjustment is identical for all motors and
right angle gear drives. Adjustment is accomplished by
turning the adjusting plate (613). (See figure 11 or 12).
The correct adjustment is listed on the Outline Drawing

2. After impeller adjustment, align adjusting plate (613)
WARNING
with the pump hub (614), and tightly draw coupling
flanges together with capscrews (759) and nuts
(735). (See figure 9 and 10).
3. Check shaft run out with dial indicator. For
mechanical seal installation, the run out should be
0.005 or less.
4. Set seal after impeller adjustment. Securely tighten
all set screws in the collar. Remove the spacer
between the gland plate and collar. Retain spacer for
future resetting of seal.
ENCLOSED IMPELLERS
For enclosed impellers obtain the clearance between the
adjusting plate and driver hub or spacer as specified on
the outline drawing. See Figure 11 or 12.
INSTALLING THE GREASE LUBRICATED THRUST POT
This type of thrust pot and the motor stand are
assembled on the discharge head by the factory. This
thrust pot is designed to be used with NEMA Vertical
C-face motors. The motor shaft and the pump shaft have
to be coupled with flexible coupling.
NOTE: When impellers are reset, the seal must also be
reset.
Figure 11
INSTALLATION:
1. Install both coupling halves prior to mounting
the motor. Refer to the coupling manufacturer’s
instructions.
2. Using the lifting lugs on the motor, carefully lower
the motor onto the motor stand of the thrust pot
(See Figure 13) and align the bolt holes.
3. Install the bolts finger tight.
4. Make temporary electrical connections according
to tagged leads or diagram attached to the motor.
Motor must rotate counterclockwise when viewed
from the top. See arrow on pump name plate. If
motor does not rotate counterclockwise, you can
change the rotation by interchanging any two leads.
Before beginning any alignment procedure,
make sure driver power is locked out.
Failure to lock out driver power will result in serious
physical injury.
ALIGNMENT OF FLEXIBLE COUPLING:
Alignment of the pump and motor is extreme importance
for trouble-free mechanical operation. Straight edge
alignment by an experienced installer proves adequate for
most installations.
1. Check for coupling alignment by laying a straight
edge across both coupling rims at four points 90º
apart.
2. Move motor until straight edge rests evenly at each
position. Repeat procedure until correct alignment is
achieved.
3. Install flexible sleeve between the hubs per the
manufacture’s instructions.
4. Tighten all motor bolts.
NOTE: Be sure the relief fitting (#11 in Figure 13) is
clear of paint or any other obstructive material.
Otherwise it will cause premature failure of the
thrust pot and is not covered under warranty.

6. Install the adjusting nut (#17) to hand tight.
7. With shafting all the way down and the impellers
resting on their seats, turn the adjusting nut (#17)
in counter-clockwise direction, thus lifting the shaft,
until the impellers just clear their seats and the
shaft/motor turns free by hand. This removes all
deflection from the shaft.
8. Line-up one of the holes in the adjusting nut with
the nearest hole in the driver coupling. Insert the
capscrew in the hole and tighten it.
NOTE: 1.00” and 1.18” diameter shafts are 12 tpi, 1.50"
through 2.44" are 10 tpi, all larger sizes are 8 tpi.
9. Install the bottom of the flexible coupling to the top
of the drive shaft.
10. Attach a sling to the lifting lugs of driver and hoist
the driver up. Inspect the mounting surface, register
and clean these surfaces thoroughly. If any burrs
are found, remove burrs with a smooth mill file,
cleaning thoroughly afterward. Temporarily attach
the top half of the flexible coupling to the motor
shaft.
11. Orient the motor conduit box in the required
position. Align the driver mounting holes with the
mating tapped holes on the discharge head. Lower
the driver until the registers engage and the driver
rests on the thrust pot assembly. Secure driver with
capscrews provided.
12. Secure the flexible coupling assembly.
INSTALLING THE OIL LUBRICATED THRUST POT
If the unit is supplied with a thrust pot (see Figure 14),
the thrust pot should be installed on top of the discharge
head or motor stand before installing the driver. The
driving mechanism of the thrust pot assembly is similar to
the hollow shaft motor. (See Figure 7)
1. Attach a sling to the thrust pot assembly through
the windows on the motor adapter and hoist the
assembly over the top of the discharge head.
2. Clean the mounting face with a flat file to remove
any burr of the discharge head and the thrust pot.
Lower the thrust pot assembly and orient it so that
the bolt hole on the base of the thrust pot and the
top flange of the discharge head are lined up. Install
all the bolts to secure the assembly to the discharge
head.
13. Install the coupling guard.
14. Fill the oil reservoir with recommended oil.

Consult the applicable manufacturer’s instructions for
detailed information for the prime mover (electric motor,
engine or steam turbine), coupling, driveshaft, gear
driver. Prior to startup, check the following:
1. Confirm that the following procedures described
in the “Installing the Drivers” sections have been
performed:
STARTUP PRECAUTIONS
1. All equipment and personal safety related devices
and controls must be installed and operating
properly.
2. To prevent premature pump failure at initial start-up
due to debris in the pipe system, ensure the system
has been adequately cleaned and flushed.
3. Variable speed drivers should be brought to rated
speed as quickly as possible.
A. Wiring of Driver.
B. Driver must rotate counterclockwise (CCW)
when viewed from above.
Serious damage may result if pump is run
in the wrong direction.
Do not check motor rotation unless motor
is bolted to pump and drive coupling is
match marked and removed.
Be sure to install the coupling guards
around all exposed shafts and couplings
before start up of the pump. Failure to comply may result
in severe personnel injury or death.
C. Check alignment of pump and driver.
D. Impeller adjustment has been made.
E. Mechanical seal lock collar is attached to shaft.
2. For open lineshaft pump, make sure the stuffing box
relief (bleed) line is connected (if applicable).
3. For pump with mechanical seal, make sure mechani-
cal seal is properly lubricated and all piping to seal is
connected. Also, check that all cooling, heating and
flushing lines are operating and regulated.
4. Open the air release system isolation valve. Adjust
the air release system throttling device so that it is
partially open. It should not be closed or fully open.
NOTE: Not exhausting the air or exhausting it too fast
can damage the pump.
5. All connections to driver and starting device match
wiring diagram. Voltage, phase, and frequency on
motor nameplate agree with line current.
6. Rotate shaft manually to ensure impellers are not
binding.
4. Variable speed drivers should not be adjusted or
checked for speed governor or over-speed trip
settings while coupled to pump at initial startup. If
settings have not been verified, uncouple the unit
and refer to driver manufacturer’s instructions for
assistance.
5. Running a new or rebuilt pump at slow speeds
may not provide enough flow to adequately flush
and cool the stuffing box bushing’s close running
surfaces.
6. Pumpage temperatures in excess of 200º F (93º C)
will require warm-up of pump prior to operation.
Circulate a small amount of pumpage through the
pump until the casing temperature is within 100º
F (38º C) of the pumpage temperature and evenly
heated.
PRIMING
The pump must be properly vented
through the discharge head/barrel vent
connections. This is especially important for fluids with
suction pressure close to their vapor pressures. Vent
piping must be continuously rising back to source so that
fluid cannot collect in the vent line.
The first stage impeller must always be completely
submerged. Pump must not run dry as the rotating parts
within the pump may gall and seize to the stationary
parts. The parts must be lubricated by the liquid being
pumped.
NOTE: NPSHa must always exceed NPSHr as shown on
Goulds Water Technology performance curves.
NOTE: Pump must never be throttled on the suction
side by allowing suction strainer to become
clogged.
PUMP STARTUP
7. Verify that driver bearings are properly lubricated
and check oil level in housing.
8. Check that auxiliary seal components are properly
vented.
9. Inspect discharge piping connection, valves and
pressure gauges for proper operation.
1. Partially close the valve in the discharge line.
2. Crack open suction side valves on pressurized
systems slowly. Open suction valves fully.
3. Vent system when the pump surface temperature has
reached an equilibrium.
4. Start the pump. If any abnormal noises, jerking
or vibration is noted, stop the pump immediately,
determine the cause of the abnormalities and correct
them.

CAUTION
open discharge valve. If driver overheats or there is
excessive vibration, stop the pump, determine the
causes and correct them.
Improper impeller adjustment could cause
contact between the rotating and stationary
parts, resulting in a spark and heat generation.
6. If the air release valve is manually operated, close it.
7. For open lineshaft pumps, with the pump in
operation, there should be some leakage at the
stuffing box packing. The correct leakage rate is
approximately one drop per second. Check the
temperature of the leakage as well as the discharge
head. If the pump runs hot and the leakage begins
to choke off, stop the pump and allow it to cool
down. A few light taps with a hammer on the gland
will upset the packing sufficiently to resume leakage.
After pump has cooled, restart pump and follow
preceding procedure. Run pump 15 minutes, check
leakage. If it exceeds two drops per second, adjust
packing as described in “Packing Adjustment and
Replacement”.
8. For pump with mechanical seal, if seal leaks slightly
at startup, allow a reasonable amount of time for
seal to adjust itself. Liquids with good lubricating
qualities normally take longer to wear in the seal
than liquid with lesser qualities. When a seal starts
out with a slight leak and gets progressively less
while running, it is indicative of leakage across the
seal faces. Continued running will eliminate this.
Where leakage occurs immediately and remains
constant, unaffected by running, it usually indicates
secondary seal (Shaft packing) damage, or seal faces
are warped out of flat.
Maintenance – SECTION 5
PREVENTIVE MAINTENANCE
Before initiating maintenance procedures,
disconnect (utilizing proper logout/
tagout procedures) all energy sources to the equipment
and accessories and completely discharge all parts and
accessories which retain electric charge. Failure to
comply may result in severe personnel injury or death.
Preventive maintenance includes periodic inspection
of oil level in the oil reservoir (for pump with oil lube
column), re-lubrication of electric motors, gear drives
and prime mover. Systematic inspection of the pump
and its components shall be made at regular intervals.
The frequency required depends upon the operating
conditions of the pump and its environment. See
following Preventive Maintenance Schedule. Consult
the applicable manufacturer’s instructions for detailed
information on maintenance for the prime mover,
driveshaft, electric motors and gear drives. Any deviation
in performance or operations from what is expected can
be traced to some specific cause. Variances from initial
performance will indicate changing system conditions,
wear, or impending breakdown of the unit.
PREVENTIVE MAINTENANCE SCHEDULE
(in operating hours)
Clean dirt, oil and grease from
driver and discharge head.
Clean driver ventilation passage to
prevent overheating.
Change lubrication in gear drive. 2,000 or once a year
Tighten all loose bolts and check
for excessive vibration.
If packing is grease lubricated,
add as required.
Check that there is some leakage
through stuffing box while pump is
in operation. Do not tighten gland
nuts unless necessary.
Maintain a liquid film of lubrication
between the seal rubbing faces.
Re-grease the motor bearings:

PACKING ADJUSTMENT AND REPLACEMENT
Pumps equipped with packing, shall be adjusted
whenever the leakage rate exceeds two drops per second.
If there is no leakage or the stuffing box overheats, do
not back off gland nuts while the pump is running. This
will allow the entire set of rings to move away from the
bottom of the box, without relieving pressure of the
packing on the shaft. Stop the pump and allow packing
to cool then restart the pump.
Be sure to reinstall the coupling guard
before restarting the pump.
It may be necessary to repeat this procedure several
times before proper amount of liquid comes through to
efficiently prevent overheating. If leakage is excessive,
adjust the stuffing box as follows:
1. With the pump in operation, tighten the gland nuts
one-quarter turn for each adjustment. Allow packing
to equalize against the increased pressure and
leakage to gradually decrease to a steady rate, before
making another adjustment.
Do not over tighten the stuffing box.
Excessive pressure can wear out packing
prematurely and seriously damage the shaft.
2. With the pump shut down and when packing has
been compressed to the point that the gland is about
to contact the upper face of stuffing box, remove
the split gland, add one extra packing ring and
readjust. If this fails to reduce leakage to two drops
per second, remove all packing rings and replace
with new rings.
3. Remove the packing with the aid of a packing hook.
If a lantern ring is provided, remove it by inserting
a wire hook in the slots of the ring and pull it from
the packing box. Thoroughly clean the stuffing box
of all foreign matter.
22
4. If the replacement packing is in the form of a
WARNING

continuous coil or rope, it must be cut into rings
before installing. Tightly wrap one end of the
packing material around the top shaft like one coil
spring, and cut through the coil with a sharp knife.
For re-packing sequence, refer to “Installing the
Stuffing Box” (page 12).
THRUST POT LUBRICATION AND MAINTENANCE
OIL LUBRICATED THRUST POT (SEE PAGE 19)
Pumps are shipped without oil. Oillubricated bearings must be lubricated at
jobsite.
It is a good practice to flush the oil reservoir before first
time operation and at the time of oil changes to remove
all grit particles in the oil reservoir sump. Use the same
type of oil to flush reservoir as specified for lubrication.
(See page 24 on recommended turbine oil.) Remove
drain plug (Item # 37) before flushing. Flushing oil
may be poured through oil fill opening (Item #32) after
removing oil fill plug. The proper oil level when the unit
is not running shall be not more than 1/8” to 1/4” from
the top of the oil sight gauge (Item #36). Overfilling
may result in overheating of the unit. During operation
the oil level in the sight gauge may be higher than
the recommended range mentioned above. Under no
circumstance is it allowed to rotate the unit when the oil
in the sight gauge is not at the required level.
To avoid oxidation of the anti-friction bearings during
shut-down periods lasting longer than one week, it is
recommended to fill up the oil reservoir until the oil runs
over the oil retainer tube (Item #2) and down the shaft
so that the bearings remain completely immersed in the
oil. Before start-up, do not forget to drain the excess oil
to its required level. Oil change depends on the severity
of the environment. Generally speaking, when the oil
in the sight gauge changes to a darkish brown color it
is time for an oil change. However, for a longer bearing
life, it is recommended that the oil be changed every six
months. Be sure to flush the oil reservoir (see above) with
each oil change.
The bearing is pre-lubricated at factory. Re-grease the
bearing according to the following procedure and per the
schedule in the above table.
NOTE: The bearing temperature usually rises after
re-greasing due to an excess supply of grease.
Temperature will return to normal after the
pump has run and purged the excess from the
bearings, usually two to four hours.
For most operating conditions, lithium based NLGI 2
grease is recommended. This is the grease factory used
for pre-lubrication. This grease is acceptable for bearing
temperatures of 5º to 230º F. Temperature extremes
(either high or low) may require different type grease.
Following table lists some various manufacturers’
compatible grease:
Mobil Mobilith AW2
Amoco Amolith EP2
Ashland Multilube EP2
Exxon Unirex N2
Shell Alvania EP LF2
Unocal Unoba EP2
Chevron Dura-Lith EP NLGI2
NOTE: If it is necessary to change the grease type or
consistency, the bearing must be removed and all
the old grease eliminated from the housing and
bearing.
Bearings must be lubricated properly in
order to prevent excess heat generation,
spark and premature failure.
SEASONAL SHUTDOWN
Prior to restating the pump, manually
rotate the shaft several times.
1. For oil lubricated pumps that are shut down for
an extended period of time, it is suggested that the
pump be operated for at least 15 minutes every two
weeks with oil feed wide open 2 hours before and
during startup in order to maintain a film of oil on
the shafting and shaft bearings.
2. For product (or water) lubricated pump, if the pump
is to be shut down for an extended period of time,
operate it for at least 15 minutes with adequate prelubrication every two weeks.
3. Before resuming normal operations, oil should be
changed on drivers, right angle gear and lubricating
oil system. After 15 minutes of operation, readjust
the lateral.
1. Wipe dirt from grease fittings.
2. Check relief port 180º from fitting to make sure it is
open.
3. Fill the grease cavity through the fitting until fresh
grease comes out the relief hole.
4. Ensure the relief port closes.
