damage the equipment or property. 


This symbol indicates explosive atmosphere 
zone marking according to ATEX. It is used in safety 
instructions where non-compliance in the hazardous 
area would cause the risk of an explosion. 


A 

A i l* ' This symbol is used in safety instructions to 
remind not to rub non-metallic surfaces with a dry 
cloth; ensure cloth is damp. It is used where non- 
compliance in the hazardous area would cause the 
risk of an explosion. 


Note: 


This sign is not a safety symbol but indicates 


an important instruction in the assembly process. 


1.6.2 Personnel qualification and training 

All personnel involved in the operation, installation, 
inspection and maintenance of the unit must be 
qualified to carry out the work involved. If the 
personnel in question do not already possess the 
necessary knowledge and skill, appropriate training 
and instruction must be provided. If required the 
operator may commission the manufacturer/supplier 
to provide applicable training. 


Always coordinate repair activity with operations and 
health and safety personnel, and follow all plant 
safety requirements and applicable safety and health 
laws and regulations. 


This is a summary of conditions and actions to 
prevent injury to personnel and damage to the 
environment and to equipment. For products 
used in potentially explosive atmospheres 
section 1.6.4 also applies. 


A 


DANGER 


NEVER DO MAINTENANCE WORK 
WHEN THE UNIT IS CONNECTED TO POWER 


A, 


GUARDS MUST NOT BE REMOVED WHILE 
THE PUMP IS OPERATIONAL 


A 


DRAIN THE PUMP AND ISOLATE 
PIPEWORK BEFORE DISMANTLING THE PUMP 


The appropriate safety precautions should be taken 
where the pumped liquids are hazardous. 

FLUORO-ELASTOMERS (When fitted.) 

When a pump has experienced temperatures over 
250 e C (482 e F), partial decomposition of fluoro- 
elastomers (example: Viton) will occur. In this 
condition these are extremely dangerous and skin 
contact must be avoided. 


A HANDLING COMPONENTS 
Many precision parts have sharp corners and the 
wearing of appropriate safety gloves and equipment 
is required when handling these components. To lift 
heavy pieces above 25 kg (55 lb) use a crane 
appropriate for the mass and in accordance with 
current local regulations. 

A THERMAL SHOCK 

Rapid changes in the temperature of the liquid within 
the pump can cause thermal shock, which can result 
in damage or breakage of components and should 
be avoided. 

NEVER APPLY HEAT TO REMOVE 
IMPELLER 

Trapped lubricant or vapor could cause an explosion. 

A HOT (and cold) PARTS 
If hot or freezing components or auxiliary heating 
supplies can present a danger to operators and 
persons entering the immediate area action must be 
taken to avoid accidental contact. If complete 
protection is not possible, the machine access must 
be limited to maintenance staff only, with clear visual 
warnings and indicators to those entering the 
immediate area. Note: bearing housings must not be 
insulated and drive motors and bearings may be hot. 


If the temperature is greater than 68 °C (175 °F) 
or below 5 °C (20 °F) in a restricted zone, or 
exceeds local regulations, action as above shall 
be taken.

FLOWSERVE 


FM USER INSTRUCTIONS ENGLISH 71576526-03/07 


HAZARDOUS LIQUIDS 

When the pump is handling hazardous liquids care 
must be taken to avoid exposure to the liquid by 
appropriate sitting of the pump, limiting personnel 
access and by operator training. If the liquid is 
flammable and/or explosive, strict safety procedures 
must be applied. 


1.6.4 Products used in potentially explosive 
atmospheres 


The following instructions for pumps and pump 
units when installed in potentially explosive 
atmospheres must be followed to help ensure 
explosion protection. 


Gland packing must not be used when pumping 
hazardous liquids. 


/f\ CAUTION 


PREVENT EXCESSIVE EXTERNAL 


PIPE LOAD 


Do not use pump as a support for piping. Do not 
mount expansion joints, unless allowed by 
Flowserve in writing, so that their force, due to 
internal pressure, acts on the pump flange. 


/f\ CAUTION 


ENSURE CORRECT LUBRICATION 


(See section 5, Commissioning, startup, operation 
and shutdown.) 


/f\ CAUTION 


START THE PUMP WITH OUTLET 


VALVE PART OPENED 


(Unless otherwise instructed at a specific point in the 
User Instructions.) 


This is recommended to minimize the risk of 
overloading and damaging the pump motor at full or 
zero flow. Pumps may be started with the valve 
further open only on installations where this situation 
cannot occur. Pump outlet valve shall may need to 
be adjusted to comply with the duty following the 
run-up process. (See section 5, Commissioning 
start-up, operation and shutdown.) 


/f\ CAUTION 


NEVER RUN THE PUMP DRY 


/f\ CAUTION 


INLET VALVES TO BE FULLY OPEN 


WHEN PUMP IS RUNNING 


Running the pump at zero flow or below the 
recommended minimum flow continuously will cause 
damage to the seal. 


^ CAUTION | nn N qt RUN THE PUMP AT 
ABNORMALLY HIGH OR LOW FLOW RATES 


Operating at a flow rate higher than normal or at a 
flow rate with no backpressure on the pump may 
overload the motor and cause cavitation. Low flow 
rates may cause a reduction in pump/bearing life, 
overheating of the pump, instability and 
cavitation/vibration. 


The terminology and procedures ensure that the 
installed pump is in compliance with the European 
Directive 94/9/EC, known as the ATEX Directive, which 
is mandatory in Europe and may also be specified in 
other countries. Where applicable, both electrical and 
non-electrical equipment must meet the requirements 
94/9/EC. 

Even if the installation is in a region where ATEX is not 
the applicable regulation, the general measures 
described shall be followed to ensure safe operation. 

The measures are explained under the headings of: 

• Avoiding excessive surface temperature 

• Preventing build up of explosive mixtures 

• Preventing the generation of sparks 

• Preventing leakages 

• Maintaining the pump to avoid hazard 

1.6.4.1 Scope of compliance 

&> 

W Use equipment only in the zone for which it is 
appropriate. Always check that the driver, drive 
coupling assembly, seal and pump equipment are 
suitably rated and/or certified for the classification of 
the specific atmosphere in which they are to be 
installed. 

Where Flowserve has supplied only the bare shaft 
pump, the Ex rating applies only to the pump. The 
party responsible for assembling the pump set shall 
select the coupling, driver and any additional 
equipment, with the necessary CE Declaration of 
Conformity establishing it is suitable for the area in 
which it is to be installed. 

The output from a variable frequency drive (VFD) can 
cause additional heating affects in the motor and so, for 
pumps sets with a VFD, the ATEX Certification for the 
motor must state that it is covers the situation where 
electrical supply is from the VFD. This particular 
requirement still applies even if the VFD is in a safe 
area.

Maximum surface temperature (Temperature Class) 
(see section 1.6.4.3) 


1.6.4.3 Avoiding excessive surface temperatures 

€) ENSURE THE EQUIPMENT TEMPERATURE 
CLASS IS SUITABLE FOR THE HAZARD ZONE 


Pumps have a temperature class as stated in the 
ATEX Ex rating on the nameplate. These are based 
on a maximum ambient of 40 q C (104 °F); refer to 
Flowserve for higher ambient temperatures. 


The responsibility for compliance with the 
specified maximum liquid temperature is with the 
plant operator. 

Temperature classification “Tx” is used when the 
liquid temperature varies and the pump could be 
installed in different hazardous atmospheres. In this 
case the user is responsible for ensuring that the 
pump surface temperature does not exceed that 
permitted in the particular hazardous atmosphere. 

If an explosive atmosphere exists during the 
installation, do not attempt to check the direction of 
rotation by starting the pump unfilled. Even a short 
run time may give a high temperature resulting from 
contact between rotating and stationary 
components. Furthermore, confinement of liquid in 
the pump and pipes must be avoided (valve closed). 
If the liquid heats up this may cause excessive 
pressure and lead to bursting of pump components. 

Where there is any risk of the pump being run against 
a closed valve generating high liquid and casing 
external surface temperatures it is recommended that 
users fit an external surface temperature protection 
device. 

Avoid mechanical, hydraulic or electrical overload by 
using motor overload trips, temperature monitor or a 
power monitor and make routine vibration monitoring 
checks. 

In dirty or dusty environments, regular checks must 
be made and dirt removed from areas around close 
clearances, bearing housings and motors. 

1.6.4.4 Preventing the build up of explosive 
mixtures 


The surface temperature on the pump is influenced 
by the temperature of the liquid handled. The 
maximum permissible liquid temperature depends 
on the temperature class and must not exceed the 
values in the table that follows. 


The temperature rise at the seals, bearings and due 
to the minimum permitted flow rate is taken into 
account in the temperatures stated.

ENSURE PUMP IS PROPERLY FILLED AND 
VENTED AND DOES NOT RUN DRY. 

Ensure pump and relevant suction and discharge 
pipeline system is totally filled with liquid at all times 
during the pump operation, so that an explosive 
atmosphere is prevented. In addition it is essential to 
make sure that seal chambers, auxiliary shaft seal 
systems and any heating and cooling systems are 
properly filled. 

If the operation of the system cannot avoid this 
condition the fitting of an appropriate dry run 
protection device is recommended (eg liquid 
detection or power monitor). 

To avoid potential hazards from fugitive emissions of 
vapor or gas to atmosphere the surrounding area 
must be well ventilated.

FM USER INSTRUCTIONS ENGLISH 71576526-03/07 


1.6.4.5 Preventing sparks 


To prevent a potential hazard from mechanical 
contact, the coupling guard must be non-sparking. 

To avoid the potential hazard from random induced 
current generating a spark the ground contact on the 
baseplate must be used. 


Avoid electrostatic charge: do not rub non- 
metallic surfaces with a dry cloth, ensure cloth is 
damp. 

Where applicable the coupling must be selected to 
comply with 94/9/EC and correct alignment must be 
maintained. 


Additional requirements for metallic pumps on 
non-metallic baseplates 

When metallic components are fitted on a non- 
metallic baseplate they must be individually earthed 
(grounded). 


1.6.4.6 Preventing leakage 


The pump must only be used to handle liquids 
for which it has been approved to have the correct 
corrosion resistance. 


Avoid entrapment of liquid in the pump and associated 
piping due to closing of suction and discharge valves, 
which could cause dangerous excessive pressures to 
occur if there is heat input to the liquid. This can occur 
if the pump is stationary or running. 

Bursting of liquid containing parts due to freezing 
must be avoided by draining or protecting the pump 
and ancillary systems. 

Where there is the potential hazard of a loss of a 
seal barrier fluid or external flush, the fluid must be 
monitored. 


If leakage of liquid to atmosphere can result in a 
hazard, the installation of a liquid detection device is 
recommended. 


1.6.4.7 Maintenance to avoid the hazard 

- X/ CORRECT MAINTENANCE IS REQUIRED 
TO AVOID POTENTIAL HAZARDS WHICH GIVE A 
RISK OF EXPLOSION 


The responsibility for compliance with 
maintenance instructions is with the plant 
operator. 


Where there is a risk from such tools or materials; 
maintenance must be conducted in a safe area. 

It is recommended that a maintenance plan and 
schedule is adopted. (See section 6, Maintenance.)

1.9 Noise level 

Attention must be given to the exposure of personnel 
to the noise, and local legislation will define when 
guidance to personnel on noise limitation is required, 
and when noise exposure reduction is mandatory. 
This is typically 80 to 85 dBA. 

The usual approach is to control the exposure time 
to the noise or to enclose the machine to reduce 
emitted sound. 

You may have already specified a limiting noise level 
when the equipment was ordered, however if no 
noise requirements were defined, then attention is 
drawn to the following table to give an indication of 
equipment noise level so that you can take the 
appropriate action in your plant. 

Pump noise level is dependent on a number of 
operational factors, flow rate, pipework design and 
acoustic characteristics of the building, and so the 
values given are subject to a 3 dBA tolerance and 
cannot be guaranteed. 


Similarly the motor noise assumed in the “pump and 
motor” noise is that typically expected from standard 
and high efficiency motors when on load directly 
driving the pump. Note that a motor driven by an 
inverter may show an increased noise at some 
speeds. 

If a pump unit only has been purchased for fitting 
with your own driver then the “pump only” noise 
levels in the table should be combined with the level 
for the driver obtained from the supplier. Consult 
Flowserve or a noise specialist if assistance is 
required in combining the values. 

It is recommended that where exposure approaches 
the prescribed limit, then site noise measurements 
should be made. 

The values are in sound pressure level L pA at 1 m 
(3.3 ft) from the machine, for “free field conditions 
over a reflecting plane”. 

For estimating sound power level LWA (re 1 pW) 
then add 17 dBA to the sound pressure value.

FM USER INSTRUCTIONS ENGLISH 71576526 - 03/07 


In areas where the staff has to intervene, remember 
that when the level of the sound pressure is: 

• below 70 dBA: it is not necessary to take special 
precautions. 

• above 70 dBA: people working continuously in 
the machine room must be supplied with 
protective devices against noise. 

• below 85 dBA: no particular measures need to 
be taken for casual visitors staying in the room 
during a limited period. 

• above 85 dBA: the room must be considered as 
a dangerous area because of the noise and a 
warning sign must be fixed at each entry 
warning the people coming into the room, even 
for a short period, that they must wear hearing 
protection. 

• above 105 dBA: special hearing protection 
adapted to this noise level and to the spectral 
noise components must be installed and a 
warning sign to this effect erected at each entry. 
The staff in the room must wear ear protection. 

Make sure that the noise, which travels through the 
walls and windows, does not generate too high 
noise levels in the machine room's surroundings. 

2 TRANSPORT AND STORAGE 

2.1 Consignment receipt and unpacking 

Immediately after receipt of the equipment it must be 
checked against the delivery and shipping 
documents for its completeness and that there has 
been no damage in transportation. 

Any shortage and or damage must be reported 
immediately to the Flowserve and received in writing 
within one month of receipt of the equipment. Later 
claims cannot be accepted. 

Check any crates, boxes and wrappings for any 
accessories or spare parts which may be packed 
separately with the equipment or attached to side 
walls of the box or equipment. 

Each product has a unique serial number. Check 
that this number corresponds with that advised and 
always quote this number in correspondence as well 
as when ordering spare parts or further accessories. 

2.2 Handling 

2.2.1 General instructions concerning handling 

Boxes, crates, pallets or cartons may be unloaded 
using fork lift vehicles or slings dependent on their 
size and construction. See 2.3.1 for positioning of 
slings. 

To lift heavy pieces above 25 kg (55 lb), use a winch 
adapted to the mass and in accordance with the 
current local regulations. 


To lift machines or pieces with one or several 
suspension rings, only use hooks and chains in 
compliance with the local regulations concerning 
safety. 

Never put cables, chains or ropes directly on or in 
the suspension rings. Cables, chains or lifting ropes 
must never present excessive bending. 

Never bend the lifting hooks, suspension rings, 
chains, etc... which should only be made to endure 
stresses within calculated limits. Remember that the 
capacity of a lifting device decreases when the 
direction of the lifting force direction makes an angle 
with the device axis. 

To increase the safety and the efficiency of the lifting 
device, all the lifting elements must be as 
perpendicular as possible. If necessary a lifting 
beam can be placed between the winch and the 
load. 

When heavy pieces are lifted up, never stay or work 
under the load or in the area which could be in the 
path of the load if it were to swing or fall away. 

Never leave a load hanging from a winch. The 
acceleration or the slowing-down of lifting equipment 
must stay in the safety limits for the staff. 

A winch must be positioned in such a way that the 
load will be raised perpendicularly. Where possible 
necessary precautions must be taken to avoid the 
swing of the load, using for example two winches 
making approximately the same angle, below 30°, 
with the vertical.

4 INSTALLATION 


Equipment operated in hazardous locations 
must comply with the relevant explosion protection 
regulations. See section 1.6.4, Products used in 
potentially explosive atmospheres. 


All equipment must be grounded. 


4.1 Location 

The pump should be located to allow room for 
access, ventilation, maintenance and inspection with 
ample headroom for lifting and should be as close 
as practicable to the supply of liquid to be pumped. 



4.2 Foundation 


A CAUTION 


There are many methods of installing 
pump units to their foundations. The correct method 
depends on the size of the pump unit, its location 
and noise vibration limitations. Non-compliance with 
the provision of correct foundation and installation 
may lead to failure of the pump and as such would 
be outside the terms of the warranty. 

Anchor bolts must be appropriate for the foot bolt 
holes. Use anchor bolts of accepted standards and 
sufficient length so that they may be clamped safely 
in the grout. 






NF E 27 811 


Provide sufficient space in the foundation to 
accommodate the anchor bolts. If necessary, provide 
concrete gullets. 


a) Levelling on the suction flange with a frame level 
or on the discharge flange with a levelling 
instrument. 

b) Admissible defect 0.5 mm for 1 meter (0.02 in

4.3 Piping 


The user must verify that the equipment is 
isolated from any external sources of vibration. 


A CAUTION 


Protective covers are fitted to the 


pipe connections to prevent foreign bodies entering 
during transportation and installation. Ensure that 
these covers are removed from the pump before 
connecting any pipes. 


4.3.1 Suction and discharge piping 

The dimensions of the pipes do not directly depend 

on suction and discharge diameters of the pump: 

a) First, choose a flow speed < 2 m/s (7 ft/s) at 
suction, and about 3 m/s (10 ft/s) at discharge. 

b) Take into account the available NPSH, which 
must be superior to the required NPSH of the 
pump. 


A caution

A caution 


Never use pump as a support for 


Do not mount expansion joints in 


such a way that their force, due to internal pressure, 
may act on the pump flange. 


Maximum forces and moments allowed on the pump 
flanges vary with the pump size and type. These 
external strains may cause misalignment, heating of 
the bearings, vibrations and the possible failure of 
the pump casing. 


When designing the pipework (§ 5.3.1, § 5.3.2, § 
5.3.3) take necessary precautions in order not to 
exceed maximum allowed strains. 


Forces and moments applied to the pump flanges 
must never exceed the values shown in the following

A It is important to be aware of the EUROPEAN 
DIRECTIVE on electromagnetic compatibility when 
wiring up and installing equipment on site. Attention 
must be paid to ensure that the techniques used during 
wiring/installation do not increase electromagnetic 
emissions or decrease the electromagnetic immunity of 
the equipment, wiring or any connected devices. If in 
doubt, contact Flowserve for advice. 

Before connecting the electric power supply, if the 
device has been kept in a damp atmosphere, have 
the insulation resistance of the electric motor 
checked. 

This resistance should have a value of not less than 
5 000 ohms for each volt of the supply. 

Carry out the ground connections according to the 
current local regulations. 


Setting of the control manometer 


/l\ CAUTION 


Do not tighten flanges before the final 


check (see § 4.3.4). 

A— R Never connect the electric motor 
before the setting has been completely finished. 


4.3.4 Final checks 

a) Check the tightening of anchor bolts. Tighten 
them if necessary. 

b) Check that protective covers on suction and 
discharge flanges are removed. 

c) Check that holes of piping flanges are parallel 
and correspond to those of the pump. 

d) Tighten suction and discharge flanges. 

e) If it is planned, connect piping (hydraulic, 
pneumatic, sealing system). 

f) Control seal and the working of auxiliary piping. 

4.4 Electrical connections 


4.4.1 Safety conditions about electrical 
connections 


A 


DANGER 


Electric connections must be carried 
out by a qualified electrician, following the local rules 
and regulations in force. 


It is important to be aware of the EUROPEAN 
DIRECTIVE on potentially explosive areas where 
compliance with IEC60079-14 is an additional 
requirement for making electrical connections. 


'Avoid mechanical, hydraulic or electrical 
overload by using motor overload trips or a power 
monitor and make routine vibration monitoring. 


The motor must be protected. The protection must 
therefore be ensured by a magneto thermal breaker 
located between the section switch and the motor. 

This breaker can be connected to fuses. 

Use a breaker sized and provisionally adjusted to 
the current specified on the description plate. 

It is recommended to provide the power supply of 
the electric motor with a monitoring device allowing 
the machine to be shut down safely. 

A device to provide emergency stopping shall be 
fitted. 

4.4.2 Electrical supply 

Make sure that the voltage of the electrical supply 
line is correct for that specified on the motor 
description plate. 

Make sure that the supply wires have sufficient load 
capacity for the correct running of the installation. 

4.4.3 Wiring Instructions 

The motors are closed type IP 55 class E - 50 Hz 

• A 230/ A 400 V up to 3.7 kW - 50 H: 

The motors can be directly supplied with 230 or 
400 V according to the coupling (starting A a with 
230 V is possible but not advised) 

• A 400 V from 5.5 kW - 50 Hz: 

The motors can be directly supplied with 400 V 
(starting A a with 400 V is possible but not 
advised). Astatoric start is advised.

the pump (§ 5.3.1,5.3.2) and before the first start (§ 
5.4.2). 


4.5 Protection systems 

x—j The following protection systems are 
recommended particularly if the pump is installed in 
a potentially explosive area or is handling a 
hazardous liquid. If in doubt consult Flowserve. If 
there is any possibility of the system allowing the 
pump to run against a closed valve or below 
minimum continuous safe flow a protection device 
should be installed to ensure the temperature of the 
liquid does not rise to an unsafe level. 

If there are any circumstances in which the system 
can allow the pump to run dry, or start up empty, a 
power monitor should be fitted to stop the pump or 
prevent it from being started. This is particularly 
relevant if the pump is handling a flammable liquid. 

If leakage of product from the pump or its associated 
sealing system can cause a hazard it is 
recommended that an appropriate leakage detection 
system is installed. 

To prevent excessive surface temperatures at 
bearings it is recommended that temperature or 
vibration monitoring are carried out. See sections 
5.5.4 and 5.5.5. 


If a defect of cooling can lead to temperature higher 
than those acceptable a system of cooling 
surveillance must be installed. 


Except when explicitly required by the customer in 
the specifications, when a possibility of reverse 
rotation exists the customer must install a reverse 
rotation protection device. 

The customer must install all equipment required to 
avoid water hammer. 


5 COMMISSIONING START-UP. 

OPERATION AND SHUTDOWN 

A These operations must only be carried out 
by qualified personnel. 


5.1 Direction of rotation 


A CAUTION . . ... 

_I Starting or operating pumps with the 

wrong direction of rotation can be harmful to the 

pumps. Ensure that the pump rotation is the same 

as the arrow on the pump casing. 


It is preferable to check the direction of rotation 
before installing the coupling. If not, the pump must 
be filled in with the liquid before start-up. 


A caution 


If maintenance work has been carried 


out to the site's electricity supply, the direction of 


rotation should be re-checked as above in case the 
supply phasing has been altered. 


5.2 Guarding 

A Guarding is supplied fitted to the pump set. 

If this has been removed or disturbed ensure that all 
the protective guards around the pump coupling and 
exposed parts of the shaft are securely fixed. 


5.3 Priming and auxiliary supplies 


Where there is any risk of the pump being run 
against a closed valve generating high liquid and 
casing external surface temperatures it is 
recommended that users fit an external surface 
temperature protection device. 


A caution . 

-1 Ensure all electrical, hydraulic, 

pneumatic, sealant and lubrication systems (as 
applicable) are connected and operational. 


A caution 


Ensure the inlet pipe and pump 


casing are completely full of liquid before starting 
continuous duty operation. 


These operations must be carried out by personnel 
with approved qualifications. 


5.3.1 Priming of a flooded pump 

a) Close the discharge valve, fill the pump by 
opening the suction valve. Let air escape by 
removing the plug located on the piping. 

b) The discharge pipe is headed and there is a by¬ 
pass valve on the check valve, open slightly the 
discharge valve and the by-pass of the check 
valve. 

c) When the pump is totally free of air bubbles, 
replace the plugs.

SHIELD GRID ON THE MOTOR STOOL 


f) Open all inlet valves (if existing). 

g) Close the outlet valve and the bypass valve. 

h) Ensure inlet pipe and pump casing are 
completely full of liquid. 


5.4.2 First pump start-up 


A CAUTION „ . , , t „ 

-1 Suction valves must be fully open 

when pump is running. Never run the pump dry, it 

will cause damage. 


a) Start motor and check outlet pressure. 

b) If pressure is satisfactory, slowly OPEN the 
outlet valve. 

c) Do not run the pump with the outlet valve closed 
for a period longer than 30 seconds. 

d) If NO pressure, or LOW pressure, STOP the 
pump. Refer to fault finding chart for fault 
diagnosis. 


The pump should run smoothly and without 
vibration. 


The pump must never run at a capacity less than 
10 % of the best efficiency point. 

A Never remove a plug when the pump is 
running. 

5.5 Running the pump 


* Without foot valve: 

Priming may be accomplished by means of venting 
system. 


___I Foot valves are not recommended when 

the pumped liquid has suspended solid particles. 
They may lodge between foot valve seat and 
shutter. 


5.5.1 Venting the pump 

A Vent the pump to enable all trapped air to 
escape taking due care with hot or hazardous 
liquids. 

Under normal operating conditions, after the pump 
has been fully primed and vented, it should be 
unnecessary to re-vent the pump.

5.5.2 Pump fitted with a stuffing box 

If the pump has a packed gland there must be some 
leakage from the gland. Gland nuts should initially 
be finger-tight only. Leakage should take place soon 
after the stuffing box is pressurized. If no leakage 
takes place the packing will begin to overheat. If 
overheating takes place the pump should be 
stopped and allowed to cool before being re-started. 
When the pump is re-started it should be checked to 
ensure leakage is taking place at the packed gland. 

/^\ When adjusting an operating stuffing box 
(shield grids removed for this operation), the 
operator must be very careful. Safety gloves are 
compulsory and loose clothes are not allowed 
(above all to the arms) to avoid being caught by the 
pump shaft. 

The pump should be run for ten minutes with steady 
leakage and the gland nuts tightened by 10 degrees 
at a time until leakage is reduced to an acceptable 
level. 

The temperature of the gland should be checked 
after each round of tightening. If the temperature 
starts to climb rapidly then back off the gland nuts 
until the temperature drops down. Wait for the 
temperature to stabilize before tightening again. 

The leakage must not be reduced below a rate of 20 
drops per minute. Bedding in of the packing may 
take several hours. 



A Shield grids being removed during installation 
of the gland packing, it must be ensured that they 
are replaced as soon as this operation is completed. 

5.5.3 Pump fitted with a mechanical seal 

A mechanical seal ensures a seal without leakage 
and does not need any adjustment. Nevertheless if a 
light leakage occurs during start-up, it should 
disappear after the initial running in of the friction 
faces. 


2445 4200 4213 



/f\ CAUTION 


With a mechanical seal, the 


maximum temperature is limited to 80 °C (176

/j\ CAUTION 


NEVER RUN A MECHANICAL SEAL 


DRY, EVEN FOR A SHORT WHILE. 


SAFETY INSTRUCTIONS WHEN THE PUMP IS 
RUNNING: 

A If hot or freezing components of the machine 
can present a danger to operators, they must be 
shielded to avoid accidental contact. If a 100 % 
protection is not possible, the machine access must 
be confined to the maintenance staff only. 

A If the temperature is greater than 80 q C (176 
°F), a warning plate must be clearly placed on the 


pump. 

danger | t j s str j ct |y forbidden f 0 open switch 
cupboards, switch boxes, or all other live electric 
equipment. If it is necessary to open them in order to 
take readings, to carry out tests or adjustments for 
example, only a skilled technician may do them with 
adapted tools. Make sure that physical protections 
against electrical risks are used. 


5.5.4 Bearings 

> c_/ If the pumps are working in a potentially 
explosive atmosphere, temperature or vibration 
monitoring at the bearings is recommended. If 
bearing temperatures are to be monitored it is 
essential that a benchmark temperature is recorded 
at the commissioning stage and after the bearing 
temperature has stabilized. 

• Record the bearing temperature (t) and the 
ambient temperature (ta) 

• Estimate the likely maximum ambient 
temperature (tb)

• Set the alarm at (t+tb-ta+5) °C [(t+tb-ta+10) °F] 
and the trip at 100 °C (212 °F) for oil lubrication 
and 105 °C (220 °F) for grease lubrication 
It is important, particularly with grease lubrication, to 
keep a check on bearing temperatures. After start up 
the temperature rise should be gradual, reaching a 
maximum after approximately 1.5 to 2 hours. This 
temperature rise should then remain constant or 
marginally reduce with time. 


5.5.5 Normal vibration levels, alarm and trip 

For guidance, pumps generally fall under a 
classification for rigid support machines within the 
International rotating machinery standards and the 
recommended maximum levels below are based on 
those standards. 


A CAUTION 


Alarm and trip values for installed 


pumps should be based on the actual 
measurements (N) taken on site on the bearing 
housings of the pump in the fully commissioned as 
new condition. 


The example (N) value is given for the preferred 
operating flow region (typically this may extend to 70 
to 120 % of the pump best efficiency point); outside 
the preferred flow region the actual vibration 
experienced may be multiplied by up to 2. 

These standard values can vary with the rotational 
speed and the power absorbed by the pump. For 
any special case, do not hesitate to consult us. 

Measuring vibration at regular intervals will then 
show any deterioration in pump or system operating 
conditions.

5.6 Stopping and shutdown 


^ _I According to hydraulic conditions of 

the installation and its automation degree, stop and 
restart procedures can have different forms. 
Nevertheless all of them must respect imperatively 
the following rules: 


5.6.1 Stopping < 1 hour 

a) Isolate motor.

entirely. 

g) Turn once per week the pump shaft of one or 


two turns. 

h) Never restart the pump without carrying out the 
verifications recommended before starting (see 
§5.4.1). 


A CAUTION 


When ambient temperatures are 


likely to drop below freezing point, the pump and any 
cooling and flushing arrangements must be drained 
or otherwise protected. 


5.6.4 Restarting in continuous running 

a) Ensure that the pump is completely full of liquid. 

b) Ensure a continuous supply with a sufficient 
available NPSFI. 

c) Ensure a backpressure so that the motor power 
is not in excess.

5.7 Hydraulic, mechanical and electrical 
duty 

This product has been supplied to meet the 
performance specifications of your purchase order, 
however it is understood that during the life of the 
product these may change. The following notes may 
help the user decide how to evaluate the 
implications of any change. If in doubt contact your 
nearest Flowserve office. 

5.7.1 Specific gravity (SG) 

Pump capacity and total head in meters (feet) do not 
change with SG, however pressure displayed on a 
pressure gauge is directly proportional to SG. Power 
absorbed is also directly proportional to SG. It is 
therefore important to check that any change in SG 
will not overload the pump driver or over-pressurize 
the pump. 

5.7.2 Viscosity 

For a given flow rate the total head reduces with 
increased viscosity and increases with reduced 
viscosity. Also for a given flow rate the power 
absorbed increases with increased viscosity, and 
reduces with reduced viscosity. It is important that 
checks are made with your nearest Flowserve office 
if changes in viscosity are planned. 

5.7.3 Pump speed 

Changing pump speed effects flow, total head, 
power absorbed, NPSHr, noise and vibration. Flow 
varies in direct proportion to pump speed, head 
varies as speed ratio squared and power varies as 
speed ratio cubed. The new duty, however, will also 
be dependent on the system curve. If increasing the 
speed, it is important therefore to ensure the 
maximum pump working pressure is not exceeded, 
the driver is not overloaded, NPSH A > NPSH R , and 
that noise and vibration are within local requirements 
and regulations. 

5.7.4 Net positive suction head (NPSHa) 

NPSH available (NPSH A ) is the head available at the 
impeller inlet, above the vapor pressure of the 
pumped liquid. 

NPSH required (NPSHr) is the minimum head required 
at the impeller inlet, above the vapor pressure of the 
pumped liquid, to avoid excessive cavitation and 
extreme performance degradation. 

It is important that NPSH A > NPSHr. The margin 
between NPSH A > NPSHr should be as large as 
possible. 


If in doubt please consult your nearest Flowserve 
office for advice and details of the minimum 
allowable margin for your application. 

5.7.5 Pumped flow 

Flow must not fall outside the minimum and 
maximum continuous safe flow shown on the pump 
performance curve and or data sheet. 

5.8 Pumps for Food Use or Potable 
Water 

If the pump has not been specifically ordered for a food 
or drinking water application it must not be used for 
these types of applications. If it has been ordered for 
this type of application the following recommendations 
are to be followed. 


5.8.1 Cleaning prior to operation 

Pumps that are to be used for a food or drinking water 
application should be cleaned before being put into 
initial operation and after the installation of spare parts 
that are in contact with the liquid. 

Cleaning once the pump has been commissioned will 
depend on the application and operating conditions. 
The user must ensure that the cleaning procedures are 
suitable for the application and operating conditions, 
and local regulations. 

6 MAINTENANCE 


6.1 General 


If a belt drive is used, the assembly and 
tension of the belts must be verified during regular 
maintenance procedure. 


In dirty or dusty environments, regular checks 
must be made and dirt removed from areas around 
close clearances, bearing housings and motors. 


A It is the plant operator's responsibility to 
ensure that all maintenance, inspection and 
assembly work is carried out by authorized and 
qualified personnel who have adequately 
familiarized themselves with the subject matter by 
studying this manual in detail (see also section 
1 . 6 . 2 ). 


Any work on the machine must be performed when it 
is at a standstill. It is imperative that the procedure 
for shutting down the machine is followed, as 
described in section 5.6. 


If any change in NPSH A is proposed, ensure these O n completion of work all guards and safety devices 

margins are not significantly eroded. Refer to the must *-* e re_ i ns talled and made operative again, 

pump performance curve to determine exact 
requirements particularly if flow has changed.

Before restarting the machine, the relevant 
instructions listed in section 5, Commissioning, start 
up, operation and shutdown must be observed. 

Oil and grease leaks may make the ground 
slippery. Machine maintenance must always 
begin and finish by cleaning the ground and the 
exterior of the machine. 

If platforms, stairs and guardrails are required for 
maintenance, they must be placed for easy access 
to areas where maintenance and inspection are to 
be carried out. The positioning of these accessories 
must not limit access or hinder the lifting of the part 
to be serviced. 

When air or compressed inert gas are used to clean 
the machines, the operator and those people in the 
vicinity must be careful and have appropriate gas- 
protection, wearing at least eye protectors. 

Do not spray air or compressed inert gas on skin. 

Do not direct an air or gas jet towards other people. 

Never use air or compressed inert gas to clean 
clothes. 


d) Verify the condition of the gaskets 

e) Gland packing must be adjusted correctly to give 
visible leakage and concentric alignment of the 
gland follower to prevent excessive temperature 
of the packing or follower. Mechanical seals 
should present no leakage. 

f) Check for any leaks from gaskets and seals. 

The correct functioning of the shaft seal must be 
checked regularly. 

g) Check bearing lubricant level, and if the hours 
run show a lubricant change is required. 

h) Check that the duty condition is in the safe 
operating range for the pump. 

i) Check vibration, noise level and surface 
temperature at the bearings to confirm 
satisfactory operation. 

j) Check the tightness of the connections,. 

k) Check dirt and dust is removed from areas 
around close clearances, bearing housings and 
motors. 

l) Check coupling alignment and re-align if 
necessary. 

m) Verify the correct operation of the system. 

The equipment used for maintenance and 

disassembly in an ATEX zone must be in conformity 

with the requirements zone. 


Before working on the pump, take measures to 
prevent an uncontrolled start. Put a warning board 
on the starting device with the words: 

"Machine under repair: do not start". 


Our specialist service personnel can help with 
preventative maintenance records and provide 
condition monitoring for temperature and vibration to 
identify the onset of potential problems. 


With electric drive equipment, lock the main switch 
open and withdraw any fuses. Put a warning board 
on the fuse box or main switch with the words: 

"Machine under repair: do not connect". 

Never clean pieces with inflammable solvents or 
carbon tetrachloride. 


If any problems are found the following sequence of 
actions should take place: 

a) Refer to section 7, Faults; causes and remedies, 
for fault diagnosis. 

b) Ensure equipment complies with the 
recommendations in this manual. 

c) Contact Flowserve if the problem persists. 


Protect yourself against toxic fumes when cleaning 
pieces with cleaning agents. 

6.2 Maintenance schedule 

\—r It is recommended that a maintenance plan 
and schedule is adopted, in line with these User 
Instructions. It should include the following: 

a) The pump must be completely vented and 
drained and rendered inert before any 
disassembly operation. 

b) Any auxiliary systems installed must be 
monitored, if necessary, to ensure they function 
correctly. 

c) During cleaning of the pump ensure the 
compatibility between the cleaning products and 
the gaskets.

6.2.2 Routine inspection (daily/weekly) 


A CAUTION 


The following checks should be made 


and the appropriate action taken to remedy any 
deviations: 


a) Check the behavior of the pump while running: 
noise level, vibrations, bearings temperature, 
flow rate and pressure. 

b) Pump fitted with a stuffing box: leakage of 20 
drops per minute. 

c) Pump fitted with a mechanical seal: no leakage. 

d) Check the level and condition of oil lubricant. On 
grease lubricated pumps, check running hours 
since last recharge of grease or complete 
grease change. 


6.2.3 Periodic inspection (6 monthly) 

Check pump running records for hourly usage to 
determine if bearing lubricant requires changing. 


Note: 


If a check shows a bad running of the 


motor pump unit, the user must: 

a) Refer to the "fault finding chart" chapter 7 of this 
leaflet to apply the recommended solutions. 

b) Ensure that your equipment corresponds to the 
arrangements of this leaflet 

c) Contact Flowserve after-sales Department if the 
problem persists. 


6.2.5 Gland packing 

6.2.5.1 Pump fitted with a packed gland 

A well run in and correctly adjusted packing gland 
requires little maintenance 
If, after some time, the leakage becomes too great, 
the gland should be tightened again in order to 
return these to a normal level. 

If re-tightening is not possible, new packing must be 
installed. 

6.2.5.2 Gland packing inspection and removal 

a) Remove the shield guards 

b) Slide back the gland 

c) Remove the packing rings with an extractor 
designed for this purpose (including the lantern 
ring if it exists; note its position and its direction 
of rotation). 

d) Inspect the state of the sleeve surface; the 
presence of many marked grooves will indicate 
that it must be replaced. 

e) Carefully clean the different pieces of the 
packing gland. 

6.2.5.3 Gland packing fitting 

If the packing is supplied as cord the packing must 
be cut so that the external diameter is lightly 
tightened and there is an initial gap between the 
sleeve and the packing ring. 


6.2.4 Mechanical seals 

The current maintenance is limited to seal control. It 
is necessary to detect any small leakage which 
announces the beginning of the deterioration of 
friction faces or secondary seal elements (rings, 
bellows, synthetic membranes). It is advisable to 
stop the pump as soon as possible. Have an 
approved seal vendor replace or repair the seal. 


2445 4200 4213 



For that purpose, wind the packing helically around 
the shaft sleeve or a chuck of the same diameter. 
(Take precautions to avoid damaging sleeve).

6.2.6 Internal coating 

If the pump has an internal coating, this coating 
must be inspected periodically. Any wear or cracks 
of the coating found must be immediately repaired. 
Failure to do this may lead to accelerated wear of 
the coating during operation and corrosion of the 
exposed base metal, depending on the material and 
pumped liquid. Special attention must be paid to the 
coating edges. Any loss of coating material is 
considered to be normal wear and tear on the pump 
and is not considered as warranty. Flowserve has 
applied the coatings according to the supplier's 
instructions but will not be held responsible for 
coating wear or cracks that may develop over time. 


To ensure continued satisfactory operation, 
replacement parts to the original design specification 
should be obtained from Flowserve. 


Any change to the original design specification 
(modification or use of a non-standard part) will 
invalidate the pumps safety certification. 

6.3.2 Storage of spares 

Spares should be stored in a clean dry area away 
from vibration. Inspection and re-treatment of 
metallic surfaces (if necessary) with preservative is 
recommended at 6 monthly intervals. 

6.4 Recommended spares 

[1410], [2250], [4610], [4130] 

Destroy all the gaskets after dismantling, replace 
them when reassembling. 

After serving during two years, replace the gland 
packing. 


6.5 Disassembly 

A Refer to section 1.6, Safety, and section 6
