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 hazard o us. An y press ure vessel can explode,
rupture, or discharge its contents if sufficiently ove r press u r i zed causi n g deat h, 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.

mounting plate (189). Floor space and head room allotted
to the unit must be sufficient for removal from the sump
or tank.

PREPARATION FOR INSTALLATION

3

Vertical units are shipped completely assembled except
for level controls and motors. Make sure all bolts are
securely tightened. Use a torque wrench on all
non-metallic joints. Bolt and nut torque values should not
exceed those shown in the chart in Appendix I.

INSTALLATION OF UNIT IN PIT

1. Inspect pump and any accessories packed with the
unit to assure no damage has occurred during transit.

NOTE: Motors are shipped separately and should
also be inspected.

Install the pump assembly in the pit before mounting
the motor to prevent damage.

$

When handling the pump unit, it is very important
to pick up the unit by the top to prevent damage to
the pump.

2. A rope or sling should be attached to the bearing
pedestal (108) or the mounting plate (189). Serious
damage may result if the unit is picked up by the
column shaft (192) or discharge pipe (195). The

recommendations included with the controls.

pump assembly must be lowered carefully into the
pit. Care must be taken to guide the pump as it is
lowered into the pit to avoid striking the sides.

3. When the mounting plate (189) is resting in the
proper position, check the level of the plate, and shim
if necessary to level the unit. The pump shaft must be
vertical to avoid a bending stress on the shaft column,
and to avoid bearing damage during operation. Check
the shaft column (192) with a level to be sure the unit
is straight and plumb.

4. Bolt down the mounting plate, and be sure it is
supported on all four sides.

NOTE: There should be a minimum of 4 to 12
inches between the bottom of the suction strainer
and the bottom of the tank of pit.

For higher flow pumps, this clearance may be
specified as greater; check your outline drawing.

4550 IOM 5/08 13

5. Be sure the source of lubrication to the line bearings
on 4550 Series vertical pumps has been connected if
an external flush source is required. Check all fittings
at the line bearings to be sure no damage has
occurred during shipment.

6. Connect level control, if the pump is so equipped.

ASSEMBLY OF MOTOR TO MOTOR
SUPPORT

If motor is shipped from ITT Goulds' factory, both
coupling halves will be assembled on shafts in their
correct positions. If motor is shipped direct or furnished
by customer, the motor half coupling must be fitted on
motor shaft.

Place motor on motor support (240) and tighten hex cap
screws snugly.

ROTATION CHECK

Before coupling is connected, motor should be wired and
the direction of rotation checked. A rotation arrow is
located on the motor support (240).

IMPELLER ADJUSTMENT - ALL

s! CAUTION

Serious damage may result if pump is run in the
wrong direction.

CONNECTION OF PIPING

Connect discharge piping to discharge pipe flange (195)
above mounting plate (189). This piping should be
independently supported, should align naturally with the
discharge flange, should be as direct as possible, and
should have a minimum number of fittings. A gate valve
should be used for flow control. There should be no strain
on the piping, and a properly restrained expansion joint
must be used.

s

! WARNING

Never draw piping into place by forcing at the
flange connections of the pump. This may impose
dangerous strains on the unit and adversely affect
the operation of the pump resulting in physical
injury and damage to the equipment.

ALIGNMENT OF FLEXIBLE
COUPLING

Check for coupling alignment by laying a straight edge
across both coupling rims at four points 90 degrees apart.
When the straight edge rests evenly at all four points, the
coupling will be in correct alignment. Tighten hex cap
screws (370U).

1. Loosen bearing cap set screw.

2. Loosen clamping screw in adjusting collar (283A).

3. Slowly rotate adjusting collar counterclock-wise
while pushing down on shaft, and rotate shaft until
you feel the impeller touch the casing face.

4. Place a dial indicator on the end of the shaft. Rotate
the collar clockwise (CW), raising the shaft to the
clearance specified in Table 1.

NOTE: For “Quick Field” adjustment, rotate the
collar 90° clockwise, while securing the shaft.

5. Re-lock adjusting collar clamping screw (283A).

PREPARATION FOR OPERATION

MOTOR ASSEMBLY

When the motor is furnished by the customer, the motor
coupling half must be installed. Place motor on motor
support, start the mounting bolts into the motor, and
securely tighten the motor mounting bolts.

MOTOR BEARINGS

Check and follow motor manufacturer's lubrication
instructions.

ROTATION CHECK

Before coupling sleeve is connected, the motor should be
wired and the direction of rotation checked. The motor
should be rotating in a clockwise (CW) direction when
looking down on top of the motor.

s

! WARNING

Serious damage could occur if pump is operated in
the wrong direction.

After the proper motor rotation direction is established,
loosen the motor coupling half and install the coupling
sleeve. Adjust the motor coupling half and tighten. Rotate
the coupling to insure no binding occurs and install the
coupling guard. Proper alignment of the pump and motor
is of extreme importance for trouble free mechanical
operation. Check the coupling alignment by laying a
straight-edge across both coupling hubs at four points, 90
degrees apart.

PIPING THE PUMP

The pump discharge pipe is connected to the process
piping above the mounting plate. The piping should be as
direct as possible with a minimum number of fittings. It is
recommended that a check valve be installed in the pump
discharge line as close as possible to where the discharge
pipe comes through the mounting plate. This will prevent
backflow from the discharge line upon pump shutdown
and reverse rotation of the pump shaft, which could cause
serious pump damage. This is particularly critical when
the pump is on level control operation with frequent
start/stop cycles.

NOTE: It is also highly recommended for long
pump life that properly anchored bellows type
expansion joints be installed at the discharge flange
connection. See Figure 1 in Disassembly Section
for typical installations.

4550 IOM 5/08 17

COUPLING

Assure that the coupling is properly lubricated if required
by the coupling manufacturer's instructions.

CHECK FOR FREE TURNING

Before pump is started, rotate shaft by hand to be sure it is
free. If pump cannot be turned by hand, or binding or
rubbing is noticed, refer to Installation of Unit in Pit.

Install coupling guard securely before starting the pump
to prevent serious injury.

PRIMING

The pump must be full of liquid with specified
submergence head above centerline of impeller.

PUMP BEARINGS

Pump Bearings - Vertical 4550 Series

1. Upper Ball Type (Pedestal)

All vertical pumps have one ball type thrust bearing
(112) located above the mounting plate. With the
exception of sizes 4x6-10, 2x3-13, 3x4-13, 4x6-13,
6x8-13 and 8x10-15, the bearings are permanently
lubricated sealed bearings, and require no further
lubrication. To lubricate the bearing, shut off the
pump and remove the coupling guard. Remove the
grease vent plug opposite the grease fitting. Inject
grease through the fitting until it appears at the
opposite vent hole. Reinstall the coupling guard and
run the pump until it reaches operating temperature
(approximately 1-2 hours). This will allow excess
grease to purge from the bearing cavity. Shut off the
pump and reinstall the grease vent plug.

2. Lower Sleeve Type

4550 Series vertical pumps have one or more sleeve
type line shaft bearings (197B). The bearings are
nonmetallic and are self-lubricating, but must have
continuous clean liquid injected to flush the bearing
surface to clean and cool the bearing. The various
methods of flushing the bearing (s) are described as
follows:

External Clean Flush - In this arrangement the pump
unit is provided with flush tubing to all the line
bearings through the mounting plate where a
connection is provided for a continuous source of

clean liquid at a rate of 1/4 to 1/2 gpm per bearing
at 10-20 psi. This is the most desirable method of

bearing flush and will offer the greatest bearing life.

From the Pump Discharge - Bearings may be flushed
in this manner when the pumped fluid is clean and
free of solids. The flush tubing can be connected to
the discharge pipe to provide the lubricating and
cooling.

Cyclone Separator - When it is impossible to use an
external clean flush and the pumped fluid is not
clean, a cyclone separator may be used. The flush
tubing is run from the pump discharge to the cyclone
separator mounted on top of the mounting plate. The
clean fluid out of the separator is run to the line
bearings, and solids are returned back into the sump.
This method will prolong bearing life, but eventual
clogging of bearings must be expected, due to solid
buildup. Clean external flush is the best bearing flush
method.

$

Regardless of the method of bearing flush, the flush
system must be checked periodically to insure fluid
is being supplied to all the line bearings to prevent
damage to the pump.

CAUTION

OPERATION

s

! WARNING

Check motor rotation before coupling motor to
pump. Refer to Rotation Check for instructions.

$

Serious damage may result if pump is run in the
wrong rotation.

CAUTION

18 4550 IOM 5/08

START-UP PROCEDURE

Before the pump is started, turn pump by hand at the
coupling to insure it is free and does not rub or bind, and
reinstall the coupling guard. Turn on the flush to the
steady bearings if provided from an external source.
Inspect the pump casing to be sure it is submerged before
engaging the motor.

$

DO NOT operate pump at reduced capacity or with
discharge valve closed. At this point, all energy
developed by the pump will convert to heat, which
may cause either mechanical damage, or vaporizing
of pump liquid in the impeller eye, causing
cavitation.

$

DO NOT operate pump when tank level drops below
minimum pump submergence.

$

DO NOT operate pump if surging occurs.

$

DO NOT operate pump if motor overloads. This will
cause overheating of the motor and possible motor
damage.

CAUTION

CAUTION

CAUTION

CAUTION

STARTING THE PUMP

! WARNING

s

Do not run pump at greatly reduced flow because
all the motor power will go into heating the liquid in
the pump and damage may result. If this condition
exists over a long period, the temperature of the
liquid in the pump may increase until the boiling
point is reached. If this occurs, the rotating parts
are exposed to vapor with no lubrication, and they
may score or even seize to the stationary parts.
Continued operation under these conditions may
create an explosive hazard due to the confined
vapor under high pressure and temperature.

OPERATING WITH SURGE
CONDITIONS IN LINE

$

If the pump is installed with a quick-acting valve in
the discharge line that could close when the pump is
running, dangerous pressure surges may be built up
that can cause damage to the pump or line. In
services of this kind, some cushioning arrangement
must be provided to protect the pumping equipment.

CAUTION

5

1. Connect coupling, following instructions for the
particular make of coupling used. This data is
supplied separately, giving complete instructions for
connection, lubrication, alignment and maintenance.

2. Check for free turning.

3. Install coupling guard.

s

! WARNING

Never operate a pump without coupling guard
properly installed. Personal injury will occur if
pump is run without coupling guard.

4. Before pump is started, the flushing flow specified in
Pump Bearings should be started. Do not run the
pump without flush to the column bearings (197B).
(Internal for clean liquids - external for dirty liquid).

5. Starting: Pump is now ready to start. Start pump with
closed or slightly opened discharge valve. Open
immediately after starting.

OPERATIONAL CHECKS

Inspect pump carefully and frequently during the first few
hours of operation. Check motor for excessive heating.
Check motor for excessive vibration or unusual noise.

FREEZING CONDITIONS

If exposed to freezing conditions while the pump is
standing idle, liquid inside the pump must be drained.

SHUTDOWN PRACTICE

When a check valve is installed in the discharge, the
pump can be shut off without closing any valves. When
no check valve is used, the discharge valve must be
closed before the pump is stopped to prevent back flow
through the pump.

s

! WARNING

When handling hazardous and/or toxic fluids,
proper personal protective equipment should be
worn. If pump is being drained, precautions must
be taken to prevent physical injury. Pumpage must
be handled and disposed of in conformace with
applicable environmental regulation.

GENERAL COMMENTS

LUBRICATION

The ball bearing (112) supplied is greased for life. No
further lubrication is required. Column bearings (197B)
must be lubricated by an integral pumpage flush or clean
source of external liquid flush. Consult ITT Goulds
Pumps for appropriate option. Follow motor and
coupling manufacturers lubrication instructions.

MAINTENANCE

1. Periodically lubricate the upper ball bearing(s) when
equipped with grease fittings.

2. Check for noise (mechanical or hydraulic) and
vibration.

3. Check float switch operation.

4. Check flush line to the line shaft bearings for
buildup.

5. Check discharge pressure gauge periodically.

VIBRATION

It is good practice to periodically monitor vibration of the
pump. Normally, vibration level will be well below
accepted standards. Of equal importance is that the
vibration level not increase. If a problem with vibration is
encountered, refer to Troubleshooting in the Disassembly

& Reassembly Section.
