Industrial Process Pump Safety Manual
IMPORTANT SAFETY NOTICE
To: Our Valued Customers
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 www.gouldspumps.com/literature_ioms.html or by contacting
your nearest Goulds Pumps sales representative.
These manuals must be read and understood before installation and start-up.
For additional information, contact your nearest Goulds Pumps sales representative or visit our Web site at
www.gouldspumps.com.

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.

S-3

S-5
General Precautions
WARNING

Alignment:
Shaft alignment procedures must be followed to prevent catastrophic failure of drive
components or unintended contact of rotating parts. Follow coupling manufacturer’s
coupling installation and operation procedures.
WARNING
Before beginning any alignment procedure, make sure driver power is locked out. Failure
to lock out driver power will result in serious physical injury.
CAUTION

Piping:
Never draw piping into place by forcing at the flanged connections of the pump. This may
impose dangerous strains on the unit and cause misalignment between pump and driver.
Pipe strain will adversely effect the operation of the pump resulting in physical injury and
damage to the equipment.
WARNING Flanged Connections:
Use only fasteners of the proper size and material.
WARNING Replace all corroded fasteners.
WARNING Ensure all fasteners are properly tightened and there are no missing fasteners.
WARNING
Startup and Operation:
When installing in a potentially explosive environment, please ensure that the motor is
properly certified.
WARNING

Operating pump in reverse rotation may result in contact of metal parts, heat generation,
and breach of containment.
WARNING
Lock out driver power to prevent accidental start-up and physical injury.
WARNING

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.
WARNING

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.
WARNING

The coupling used in an ATEX classified environment must be properly certified and
must be constructed from a non-sparking material.
WARNING Never operate a pump without coupling guard properly installed. Personal injury will
occur if pump is run without coupling guard.
WARNING

Make sure to properly lubricate the bearings. Failure to do so may result in excess heat
generation, sparks, and / or premature failure.
CAUTION

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.

S-6
General Precautions
CAUTION

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.
WARNING Never attempt to replace packing until the driver is properly locked out and the coupling
spacer is removed.
WARNING
Dynamic seals are not allowed in an ATEX classified environment.
WARNING

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.
WARNING Ensure pump is isolated from system and pressure is relieved before disassembling pump,
removing plugs, opening vent or drain valves, or disconnecting piping.
WARNING
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.
WARNING
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.
WARNING Operator must be aware of pumpage and safety precautions to prevent physical injury.
WARNING
Lock out driver power to prevent accidental startup and physical injury.
CAUTION Allow all system and pump components to cool before handling them to prevent physical
injury.
CAUTION

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.
CAUTION Wear heavy work gloves when handling impellers as sharp edges may cause physical
injury.
CAUTION Wear insulated gloves when using a bearing heater. Bearings will get hot and can cause
physical injury.

Designation codes :
(example)
1.1 Intended use
The pump is equipped with a permanent-magnet syn-
chronous drive. It is suitable for the leak-free convey-
ance of aggressive, toxic, ignitable or hot liquids.
Vertical installation of the pumps is only possible with
grease-lubricated rolling bearings or rolling bearings
with oil mist lubrication. Please consult the manufac-
turer. The observance of the specified physical lim-
its is important for perfect functioning and safe
operation, especially with regard to explosion
protection to prevent potential sources of ignition (see
Section 2.5):
♦It must be ensured that the pump is always filled
with liquid during operation.
♦For safe pump operation, we recommend a flow
rate which lies between 0.3 and 1.1 Qopt. The
maximum operating temperature must never be
exceeded. See Section 2.5.7. In case of doubt,
you must consult the manufacturer.
♦The manufacturer must be consulted in the event
of entrainment of gas >2% as well as solids in or-
der to avoid a lack of lubrication and dry-running.
♦The plant NPSH value (NPSHA) should be 0.5 m
higher than the NPSH value of the pump
(NPSHR). See also Section 5.4.1.
Inadmissible modes of operation, even for a
short period, may result in serious damage to
the unit.
In connection with explosion protection, potential
sources of ignition (overheating, electrostatic and
induced charges, mechanical and electric sparks) may
result from these inadmissible modes of operation;
their occurrence can only be prevented by adhering to
the intended use.
Furthermore, reference is made in this connection to
the Directive 95/C332/06 (ATEX 118a) which contains
the minimum regulations for improving the occupa-
tional health and safety of the workers who may be at
risk from an explosive atmosphere.
This unit must not be operated above the val-
ues specified in the data sheet as regards the
fluid to be conveyed, flow rate, speed, density,
delivery head and operating temperature as well as
the motor rating.
The instructions contained in the operating man-
ual or contract documentation must be observed;
if necessary consult the manufacturer.
All important features are documented in the data
sheet included in the scope of delivery.
In the event of operating conditions other than those

ous substances.
If the unit is used in potentially explosive
areas, special attention is to be paid to the
sections identified with “Ex” in this operat-
ing manual.
2.1 For the customer/operator
The following must be observed:
♦The notes on safety contained in this operating
manual,
♦the prevailing regulations on accident prevention,
♦in-house work, operating and safety regulations of
the customer.
♦Hot or cold machine parts must be protected by
the customer against being touched.
♦No protective facilities may be removed when the
machine is in operation.
♦Hazards due to electricity are to be excluded.
♦Leaks of hazardous media (e.g. explosive, toxic,
hot) must be removed so that no risk arises for
people and the environment. The statutory provi-
sions are to be observed.
Caution when using the units in potentially
explosive area! Inadmissible modes of opera-
tion must be prevented.
2.2 For maintenance
In principle, work on the unit may only be performed
when it is at a standstill.
It is imperative to observe the procedure for stopping
the machine described in this operating manual. See
Section 6.3.
Pumps which convey media which are a health haz-
ard must be decontaminated.
All safety and protective facilities must be remounted
or enabled immediately after the end of work.
In the assemble state, if the safety notes (see also
Section 5.1 and 7.5.2) are observed, the magnetic
drives do not cause any risks or have any affect on
the environment.
During dismantling and assembly as well as
during transport and storage of the magnetic
drives as single components, the notes on
safety in Section 7.5.2 must be observed.
The points listed in Section 6.1 must be followed be-
fore recommissioning.

2.3 Conversion work and produc-
tion of spare parts by the cus-
tomer
Conversion of or changes to the machine are only
admissible after consultation with the manufacturer.
Original spare parts and accessories authorised by
the manufacturer serve to enhance safety.
The use of other parts may annul the liability for any
resultant consequences.
2.4 Inadmissible modes of opera-
tion
The operational safety of the machine supplied is only
guaranteed if it is used properly in accordance with
Section 1.1 of this operating manual.
The operating limits specified in the data sheet must
under no circumstances be exceeded.
2.5 Explosion protection
If the units are used in potentially explosive areas, the
measures and notes in Sections 2.5.1 to 2.5.8 are
imperative to guarantee the explosion protection.
2.5.1 Filling the unit
During pump operation the wetted interior of
the pump must always be filled with the liquid
medium.
This prevents any explosive atmosphere and the risk
of dry-running.
If the customer cannot ensure this, we rec-
ommend that appropriate monitoring facilities
be provided.
All auxiliary, heating and cooling systems
must also be carefully filled.
2.5.2 Special operating conditions
In the standard design the can chamber and
the plain bearings are cooled and lubricated
by a flushing flow.
The cooling flow may be interrupted and an inadmis-
sible rise in temperature may occur due to properties
of the liquid (e.g. sticking, possibly by an inadmissible
ingress of solids, clogging, ingress of gas etc.). Ap-
propriate monitoring facilities are to be provided. See
Section 5.6.
For safe pump operation, we recommend a flow rate
of 0.3 to 1.1 Qopt. If the pump is operated outside this
range, it must be ensured that the max. admissible
flow rate according to the pump characteristic curve is
not exceeded and that the max. admissible operating
temperature according to Section 2.5.6 is observed.
If the cooling flow is too low or there is none at all, this
may lead to an inadmissible rise in temperature on the
metallic can owing to eddy current losses.
If the flow rate is too high, the differential pressure
upstream and downstream of the plain bearings could
fall so much that a lack of lubrication or dry-running
may occur.
If the flow rate is too low, the medium may heat up so
much owing to the fluid friction that the max. admissi-
ble surface temperature of the relevant temperature
class is exceeded.
Overloading, overheating, non-observance of the de-
sign data or the incorrect selection of the magnetic
drive can lead to the decoupling of the inner and outer
magnet assemblies. As a result, eddy currents are
induced on the can and the inner and outer magnet
assemblies and an inadmissible rise in temperature
may occur.
The situation is to be remedied by providing appropri-
ate monitoring facilities. See Section 5.6.
The plant NPSH value (NPSHA) should be 0.5 m
higher than the NPSH value of the pump (NPSHR) to
prevent a lack of lubrication or dry-running of the plain
bearings.
2.5.3 Identification
The identification on the pump relates to the pump
section. A separate declaration of conformity must be
provided for the shaft coupling and motor and for
other attachments as well as corresponding identifica-
tion.
Example of the identification of the pump section:
CE Ex II 2 G/D T1-T... .
The identification indicates the theoretically available
range of the temperature classes. The admissible
temperature depending on the pump design are de-
rived in accordance with Section 2.5.6. The same
applies to the drive.
For an overall unit (pump, coupling, motor) with vari-
ous temperature classes, the lowest class in each
case applies as follows :
Example 1 : Pump T3, motor T4, coupling T4
T3 applies, i.e. the unit may only be used in atmos-
pheres which may ignite at temperatures <200 °C
(+ safety margin). The maximum medium temperature
of the pump for this example is 175 °C (see table in
Section 2.5.6).
Example 2 : Pump T4, Motor T3, coupling T4
T3 applies, i.e. the unit may only be used in atmos-
pheres which may ignite at temperatures <200 °C
(+ safety margin).

2.5.4 Check of the direction of rotation
If there is also a risk of explosion during the
installation phase, the check of the direction of
rotation must under no circumstances be con-
ducted by briefly switching on the unfilled pump in
order to prevent an inadmissible rise in temperature at
the plain bearings.
We recommend you to only perform a check
of the direction of rotation with the coupling
disengaged or with a rotating field instrument.
See also Section 6.1.2.
2.5.5 Mode of operation of the pump
The pump may only be started with the suction side
shut-off element fully opened and the discharge side
shut-off element slightly opened. Start-up against a
closed check valve is also possible. The discharge
side shut-off element is to be regulated to the operat-
ing design point directly after run-up.
See also Section 5.4.1.
Operation with closed shut-off elements in the
suction and/or discharge lines is not permitted!
There is a risk that even after a short time
high surface temperatures on the pump hous-
ing may occur owing to rapid heating of the
liquid in the pump interior.
A rapid rise in the pressure inside the pump
involves the risk of overloading to the point of
bursting.
The pump must not be in operation in the unfilled
or partially filled state (dry running). This
results in serious damage to the pump and
additional risks to the environment can
arise. Dry-running cannot only occur with an insuffi-
ciently filled interior but also in the event of
high gas contents in the liquid medium.
Operation of the pump outside the admissible operat-
ing range may also lead to dry-running (e.g. due to
evaporation in the interior).
2.5.6 Temperature limits
In normal operating mode the highest tem-
peratures are to be expected at the contact
point shaft seal/shaft (only with oil bath lubri-
cation), on the inner races of the rolling bearings and
at high medium temperatures on the metallic can.
In the case of liquids > 40 °C the surface temperature
of the pump housing is generally lower than the tem-
perature of the liquid.
If the pump is heated (e.g. heating jacket), it
must be ensured that the temperature classes
prescribed in the annex are observed.
The entire pump surface must have free contact with
the environment.
During operation of the pump it must be en-
sured that excessive deposits of dust are pre-
vented (regular cleaning) in order to prevent
the pump surface from heating to above the admissi-
ble temperature.
The plant customer must ensure that the pre-
scribed operating temperature is observed. The
maximum admissible temperature of the liquid
medium at the pump inlet depends on the tem-
perature class and the selected lining material
required in each case.
The following table contains the resultant theoretical
limit values of the temperature of the liquid medium
allowing for the temperature classes according to EN
13463-1.

2) The limit values specified for the temperature of the medium at
the pump inlet are determined for the most unfavourable case
(high speed, low flow rate, low heat capacity of the medium,
large magnetic drive ....). Under favourable operating conditions
the limit values specified may be increased by up to 10 K after
consultation with the manufacturer.
3) Consult the manufacturer for higher temperatures than 280 °C.
The admissible operating temperature of the
pump is indicated in the data sheet.
Observance of the temperature class T4 with oil
bath lubrication is not possible with the standard
shaft seal. A labyrinth seal must be used instead
of the shaft seal for the temperature class T4 and
with oil-lubricated rolling bearings.

2.5.7 Maintenance
For safe and reliable operation, it must be
ensured with regular inspection intervals that
the unit is properly serviced and kept in a per-
fect technical condition.
Example: Functioning of the rolling bearings. The
mode of operation and operating conditions largely
determine the actual service life that can be attained.
Regular checks of the bearings and there running
noise can prevent excess temperatures due to hot-
running bearings, collision of the outer magnet as-
sembly against the lantern or even defective bearing
seals. See Section 7.2.
If auxiliary systems (e.g. external flushing, cooling,
heating) are installed, a check must be made to see
whether monitoring facilities are required to safeguard
their operation.
2.5.8 Electric peripheral equipment
Electric peripheral equipment, e.g. pressure,
temperature and flow sensors etc. must com-
ply with the prevailing safety requirements and
explosion protection provisions.
3 Transport and storage
The pump or the unit must be transported
properly. It must be ensured that during
transport the pump/unit remains in the hori-
zontal position and does not slip out of the transport
suspension points.
A pump or motor can be suspended from the ring bolt
provided for this purpose.
The suspension points are not suitable for transport-
ing a complete unit, i.e. pump with base plate and
motor.
In this case, the slinging points for the ropes on the
base plate are to be used. See Figure 1.
The slinging ropes must not be attached to free shaft
ends or to the ring bolt of the motor.
Fig. 1
Directly after receipt of the goods, the consign-
ment must be checked for completeness and any
in-transit damage.
Damaged pumps must not be installed in the plant.
When unpacking magnetic drives as single
parts, the relevant notes in Section 7.5.2
must be observed.
Handle goods carefully to prevent damage.
Flange covers serve as protection during transport
and must not be removed.
If the unit is not installed immediately after delivery, it
must be put into proper storage.
It should be stored in a dry, vibration-free room as at
constant a temperature as possible.
If magnetic drives are stored as single parts,
the relevant notes in Section 7.5.2 are to be
observed.
In the case of prolonged storage conservation
agents on machined component surfaces and packing
with a desiccant may be necessary.
3.1 Return consignments

dia must be well flushed and cleaned before being
returned to the manufacturer's works.
A General Safety Certificate on the field of applica-
tion is to be enclosed with the returned goods.
Pre-printed forms are enclosed with the installation
and operating manual.
Safety precautions and decontamination methods are
to be mentioned.

4 Product description
The housing dimensions of the pump model ICM
comply with ISO 2858 / DIN EN 22858.
The technical requirements and nominal ratings of the
pump models ICM and ICMP comply with ISO 2858 /
DIN EN 22858 / ISO 15783 / DIN ISO 5199.
The sectional drawing shows the pump set-up. See
Section 9.
The metal housing 100 has an axial suction nozzle
and radial discharge nozzle. The housing drain screw
103 permits the entire pump including the can interior
to be drained.
The impeller 230 is of closed design. The back vanes
serve to offset the axial thrust. The impeller is at-
tached to the magnet assembly shaft by an impeller
nut 231 and key 940/2 and rests against the distance
washer 551/1.
The plain bearing pedestal 339 has flushing bores
which serve to dissipate the heat on the can and lubri-
cate the plain bearing cartridge 310. Depending on
the pump design, connection tapped bores can be
provided on the plain bearing pedestal to permit ac-
cess to the pump interior (e.g. for monitoring devices
or external flushing).
The plain bearing cartridge 310 encapsulates all the
individual parts of the bearing system and permits the
exchange of the complete unit in one piece. It is at-
tached to the plain bearing pedestal with hex. screws
901/1. The inner magnet assembly 859 is fitted with
permanent magnets. These magnets of the inner
magnet assembly are protected against the medium
by a corrosion-resistant metallic cover. The inner
magnet assembly and shaft are one piece.
A parallel pin 562/1 serves as an anti-torsion insert for
the plain bearing cartridge.
The inner magnet assembly accommodates axial
vanes to promote the flushing flow.
The metallic can 159 seals the pump interior against
the atmosphere to ensure it is leak-proof.
The lantern 344 is screwed against the housing with
hex. screws 901/3 and washers 554/3. Both the hous-
ing gasket 401 and the can gasket 406 are tightly
sealed through the direct action of the bolting force.
The lantern has a safety rubbing surface which pro-
tects the can against damage from the drive magnet
assembly if the rolling bearings become defective.
The hex. screws 901/5 prevent the individual parts
from falling apart when the entire slide-in unit is being
removed from the pump housing. These screws are
not provided in some pump sizes. Instead the set-
screws 904/2 perform this function.
The bearing pedestal 330 contains radial ball bearings
321 and lubrication is provided by an oil bath. The oil
bath is sealed against the atmosphere by two rotary
shaft seals 421 and a cover gasket 403. They are
sealed on both sides. The wavy spring washer 953/1
exerts an axial pre-load on the radial ball bearings and
rests against the rear bearing cover 361. The torque is
transmitted to the drive magnet assembly 858 by the
key 940/1 and the drive shaft 213.The magnets are
glued into the drive magnet assembly which is axially
secured by the hex. socket screw 914/1.
Should the can become defective, the flat gasket
400/1 at least seals the medium against the atmos-
phere for a short period.
The flushing/cooling flow is fed into the can chamber
through the flushing bores in the plain bearing pedes-
tal. The flushing flow passes through the plain bear-
ings back into the housing. The rotating magnets gen-
erate an eddy current in the can which heats the flush-
ing/cooling flow.
Design details are provided in the sectional drawing,
Section 9.
Additional information is also contained in the Bro-
chure and Pricebook.

5 Installation
5.1 Safety regulations
Equipment which is operated in potentially
explosive areas must satisfy the explosion
protection regulations.
People with a pacemaker are at risk from the
strong magnetic field of the magnetic drive. It
may be life-threatening for them to stay at a
distance of less than 500 mm to the pump.
5.2 Installation of pump/unit
The structural work must be prepared in accordance
with the dimensions in the installation drawing.
Method of installation: on a grouted base plate and
firm foundation
¾Align base plate on the ground foundation.
¾Insert foundation bolts and grout base plate.
¾Do not tighten the foundation bolts uniformly and
firmly until the mortar has set.
5.3 Alignment of pump - coupling -
motor
The following information is of a general na-
ture. If necessary, special notes of the cou-
pling and motor manufacturer are to be ob-
served.
After attachment of the base plate on the
foundation and connection of the pipes, the
alignment of the coupling must be carefully checked
and, if necessary, the unit re-aligned with the motor.
¾A coupling check and possible re-alignment is also
necessary if the pump and motor are supplied on a
common base plate and aligned.
¾Prior to alignment undo the support bracket 183
and then tighten it without stress.
¾The pump is to be aligned in all directions using a
spirit level (on shaft/discharge nozzle) (admissible
position deviation max. 0.2 mm/m).
¾A distance depending on the coupling used is to be
observed between the pump and motor shafts.
See installation drawing.
¾Use supports in the direct vicinity of the bolts foun-
dation/base plate.
Ensure that the unit cannot be started during
work without the coupling guard.
5.4 Piping
Before the pump is installed, both the suction and
supply lines as well as the discharge line are to be
cleaned.
Dirt or damage to the sealing surfaces is best avoided
if the flange covers remain on the flanges until just
before installation.
Use flange gaskets suitable for the medium.
The screw tightening torques in Section 1.2 are to be
observed for tightening the flange screws.
5.4.1 Nominal size
The operating design point of a centrifugal pump lies
at the intersection of the pump curve and the pipe
curve, see Fig. 2. The pump curve is provided by the
pump manufacturer. The pipe curve is determined
using diagrams or PC programs.
Under no circumstances can the nominal size of the
piping be derived from the connected nominal size of
the pump.
The pipe nominal size can also be determined using
the flow rate as a rough guide.

The velocity in the suction line should not exceed
2.0 m/s and 5.0 m/s in the discharge line.
When determining the suction line nominal size, the
NPSH value (net positive suction head) must also be
observed. The NPSHR value required for the pump is
specified in the data sheet.
The NPSHR available in the plant
should be at least 0.5 m higher than
the NPSHR required for the pump.
Otherwise, this will lead to a drop in the delivery head,
cavitation or even failure of the pump.
