1 Introduction and Safety

1.1 Important Safety Notice

T

o: Our Valued Customers:

User safety is a major focus in the design of our products. Following the precautions outlined in this man-

ual will minimize your risk of injury.

ITT Goulds pumps will provide safe, trouble-free service when properly installed, maintained, and operat-

ed.

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 guide-

lines outlined in this Pump Safety Manual and the Instruction, Operation, and Maintenance (IOM) man-

ual. Current manuals are available at https://www.gouldspumps.com/en-US/Tools-and-Resources/Litera-

ture/ or by contacting your nearest Goulds Pumps sales representative.

These manuals must be read and understood before installation and start-up.

1.2 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 suf

ficiently 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 con-

tents of the pump and eliminate the possibility of exposure, particularly if hazardous and/or tox-

ic. Potential hazards include, but are not limited to, high temperature, flammable, acidic, caus-

tic, explosive, and other risks.

1 Introduction and Safety

Current manuals are available at www.gouldspumps.com/literature_ioms.html or from

your local ITT Goulds Pumps sales representative. Note: Lifting devices (eyebolts,

slings, spreaders, etc.) must be rated, selected, and used for the entire load being lifted.

1.4 General precautions

ICB Installation, Operation and Maintenance Instruction 5

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. Fail-

ure 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 in-

jury 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 clear-

ance 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 oc-

cur 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 envi-

ronment are closed.

1.4 General precautions

6 ICB Installation, Operation and Maintenance Instruction

CAUTION Never operate the pump without liquid supplied to mechanical seal. Running a mechani-

cal 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 conform-

ance 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 physi-

cal 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 prop-

erly 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.

WARNING Never apply heat to remove an impeller. The use of heat may cause an explosion due to

trapped fluid, resulting in severe physical injury and property damage.

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

.

1.5 ATEX Considerations and Intended Use

Special care must be taken in potentially explosive environments to ensure that the equipment is proper-

ly maintained. This includes but is not limited to:

1.

Monitoring the pump frame and liquid end temperature.

2. Maintaining proper bearing lubrication.

3. Ensuring that the pump is operated in the intended hydraulic range.

The ATEX conformance is only applicable when the pump unit is operated within its intended use. Oper-

ating, installing or maintaining the pump unit in any way that is not covered in the Instruction, Operation,

and Maintenance manual (IOM) can cause serious personal injury or damage to the equipment. This

tured to the highest quality and safety levels.

Please contact your local Goulds representative for details on

genuine Goulds parts.

1.6 Parts

ICB Installation, Operation and Maintenance Instruction 9

2 Safety Regulations

2.1 Explosion Protection

On application of units in areas endangered to explosion measures and references in the Filling of Unit

and Maintenance sections, must be observed, so that explosion protection is guaranteed.

Filling of unit

During operation of the pump the system of the suction and pressure pipe and the pump itself must

permanently be filled with the pumped liquid.

Thus, no explosive atmosphere can develop and the danger of dry-run is avoided.

If the operator can´t guarantee that, according monitoring measures must be provided.

NOTICE:

Equally all seal casings, auxiliary systems of the shaft sealing, as well as heating and cooling

systems must be filled carefully

.

Marking

The marking of the pump refers to the pump itself. For the motor resp. further additions a separate

Declaration of Conformity

, as well as a corresponding marking must be available.

Example of marking at pump: CE Ex II 2 G c T1-T.

The marking shows the theoretically applicable range of temperature classes. The different tempera-

tures, permitted acc. to pump design, result as shown in Temperature Limits. The same is valid for the

drive.

For a whole unit (pump, motor) with different temperature classes the lowest is valid.

Rotation Control

If danger of explosion is also existing during installation, the rotation control must not be carried out

by short start-up of the empty pump, to avoid undue temperature increase in case of contact of rotating

and stationary parts.

Operation of pump

The pump must only be started up with fully opened suction side and slightly opened pressure side

valve. The start-up against closed non-return valve, however

, is possible. Immediately after the start-up

the discharge side valve must be adjusted to the operating point.

Refer to 6.1.4 Switch on drive on page 29, as well.

Operation with closed valve in suction and / or discharge pipe is not permitted!

There´s a danger, that high surface temperatures are developing at the pump casing after relatively

short time, through fast heating of the liquid inside the pump.

NOTICE:

Fast pressure increase inside the pump can lead to overload and, thus, the pump can burst.

2 Safety Regulations

10 ICB Installation, Operation and Maintenance Instruction

In Limits of Operation, Flow min. / max., the minimum flow is stated. Longer operating phases with these

flows and the named liquids don´t cause additional increase of surface temperature at the pump.

Furthermore the references in Start-up, Operation, Shut down of these operating Instructions must be

taken into consideration.

On pumps with mech. seals the permitted temperature limits can be exceeded due to dry-run. Dry run

not only can occur on insuf

ficiently filled seal casing, but also because of too much gas in the medium.

Operation of the pump out of the permitted operating range can lead to dry-run, as well.

Temperature limits

Under normal operating conditions the highest temperatures must be expected at the surface of the

pump casing and in the area of the bearings.

The surface temperature occurring at pump casing corresponds with the temperature of the pumped liq-

uid.

In the area of lantern and motor free contact of surface to environment must be given for proper cooling.

During operation of the pump it must be secured that an overabundant sedimentation of dust is avoid-

ed (regular cleaning), to prevent heating of pump surface over the permitted temperature.

The operator of the plant must secure that the defined operating temperature is observed. The max. al-

lowed temperature of the pumped liquid at suction depends on the particular temperature class.

The following table shows the theoretical temperature

limits of the pumped liquid in consideration of the temperature classes acc. to EN 13463-1.

Temperature class acc.

EN 13463-1

Temperature class acc.

EN 13463-1

T4 (135°C) 135°C

T3 (200°C) 140°C

T2 (300°C) 140°C

T1 (450°C) 140°C

The particular allowed operating temperature of the pump is shown in the data sheet and / or the or-

der confirmation resp. the type plate at the pump.

Maintenance

For a secure and reliable operation it must be secured by regular inspections, that the unit is main-

tained competently and is kept in good technical condition.

Example: Function of bearings. Operation and application conditions are essentially responsible for their

achievable life cycle.

By regular control of the lubricant and the running sound the danger of occurring over temperatures by

bearings running hot or defect bearing seals is avoided. Refer to Monitoring and 7.1.4 Cleaning of pump

on page 33.

The function of the shaft sealing must be secured by regular control.

If auxiliary systems (e.g. external flushing, cooling, heating) are installed, it must be checked, if monitor-

ing devices are necessary to secure the function.

Electrical switches and control device, instrumentation and accessories

Electric switches and control device, Instrumentation and accessories

2.1 Explosion Protection

ICB Installation, Operation and Maintenance Instruction 11

Electric switches and control devices, instrumentation and accessories must correspond with the valid

safety requirements and regulations for explosion protection.

2.2 Use acc. to Regulations

Speed, Pressure, T

emperature

Suitable safety measures must be taken at the plant to ensure that the speed, pressure and tempera-

ture of the pump and the shaft sealing do not exceed the limit values given in the data sheet and / or

order confirmation. The given admission pressures (system pressures) must also be suf

ficiently high.

Further, pressure shocks, as can occur on too fast shut down of the facility, must be kept away from the

pump (e.g. by non-return valve at pressure side, airtanks). Quick temperature changes must be avoided.

They could cause a temperature shock and lead to damage or impair the function of single components.

Permitted Nozzle Loads and Torques

Basically the suction and discharge piping must be designed in such way, that as little forces as pos-

sible are ef

fective to the pump. If that is not possible, the values shown in chapter 3.5 must not be ex-

ceeded under any circumstances. This is valid for the operation as well as for the standstill of the pump

and therefore for all possible pressures and temperatures of the unit.

NPSH

The pumped liquid must have a min. pressure NPSH at the impeller inlet, so that cavitation free work

is secured resp. a "break of

f" of the pump flow is prevented. This condition is fulfilled, when NPSH-value

of the system (NPSHA) lies above NPSH-value of the pump (NPSHR) under all operating conditions.

Attention must especially be paid to the NPSH- value on pumping liquids near the vapour pressure. If the

NPSH-value of the pump remains under, this can lead from damage of the material due to cavitation to

destruction by overheating.

The NPSH-value of the pump (NPSHR) is shown in the curves of every pump type.

Sealing, Flushing, Cooling

Suitable provisions for the regulation and monitoring of sealing, flushing or cooling are to be provided.

When handling dangerous liquids or if temperatures are high, care should be taken to ensure that the

pump ceases operating if the sealing, flushing or cooling system fails.

Sealing, flushing and cooling systems must always be operational before the pump is started up. They

should not be taken out of operation until the pump has stopped, provided that the nature of the opera-

tion allows this at all.

Back Flow

In systems where pumps are operating in closed circuits under pressure (gas cushions, steam pressure),

the pressure of the gas cushion must not be reduced via the pump, since the back flow speed may be

much higher than the operating speed, which would destroy the unit.

2.3 Unauthorized Alteration and Spare Parts Production

Alteration or changes of the machine are permitted after agreement with the manufacturer.

Original spare parts and accessory authorized by the manufacturer are serving the safety.

The use of other parts can lead to loss of liability for therefrom resulting consequences.

toed shoes, gloves, etc.) at all times. Seek assistance if necessary.

• Safe lifting points are specifically identified in this manual. It is critical to lift the equipment

only at these points. Integral lifting eyes or eye bolts on pump and motor components are

intended for use in lifting the individual components only.

NOTICE:

•

Make sure that the lifting equipment supports the entire assembly and is only used by au-

thorized personnel.

• Do not attach sling ropes to shaft ends.
