1.6.1
Summary of safety markings
These User Instructions contain specific safety
markings where non-observance of an instruction would
cause hazards. The specific safety markings are:
This symbol indicates electrical safety
instructions where non-compliance will involve a high
risk to personal safety or the loss of life.
This symbol indicates safety instructions where
non-compliance would affect personal safety and
could result in loss of life.
This symbol indicates “hazardous and toxic fluid”
safety instructions where non-compliance would affect
personal safety and could result in loss of life.
This symbol indicates safety
instructions where non-compliance will involve some
risk to safe operation and personal safety and would
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.
used in potentially explosive atmospheres
section 1.6.4 also applies.
NEVER DO MAINTENANCE WORK
WHEN THE UNIT IS CONNECTED TO POWER
GUARDS MUST NOT BE REMOVED WHILE
THE PUMP IS OPERATIONAL
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 ºC (482 ºF), partial decomposition of fluoroelastomers (example: Viton) will occur. In this
condition these are extremely dangerous and skin
contact must be avoided.
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.
This symbol is used in safety instructions to
remind not to rub non-metallic surfaces with a dry
cloth; ensure the cloth is damp. It is used in safety
instructions where non-compliance in the hazardous
area would cause the risk of an explosion.
This sign is not a safety symbol but indicates
an important instruction in the assembly process.
Personnel qualification and training
1.6.2
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.
Safety action
1.6.3
This is a summary of conditions and actions to
prevent injury to personnel and damage to the
environment and to equipment. For products
APPLYING HEAT TO REMOVE IMPELLER
There may be occasions when the impeller has either
been shrunk fit on to the pump shaft or has become
difficult to remove due to products of corrosion.
If you elect to use heat to remove the impeller, it must
be applied quickly to the impeller boss. TAKE
GREAT CARE!
Before applying heat ensure any residual hazardous
liquid trapped between the impeller and pump shaft is
thoroughly drained out through the impeller keyway
to prevent an explosion or emission of toxic vapour.
This must be carried out with the shaft in the vertical
position. On some pump sizes a cavity exists in the
impeller bore so on occasions a significant volume of
liquid may drain out.
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.
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
Page 5 of 76 flowserve.com
VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 – 10-13
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 80 ºC (175 ºF) or
below -5 ºC (23 ºF) in a restricted zone, or exceeds
local regulations, action as above shall be taken.
HAZARDOUS LIQUIDS
When the pump is handling hazardous liquids care
must be taken to avoid exposure to the liquid by
appropriate siting of the pump, limiting personnel
access and by operator training. If the liquid is
flammable and/or explosive, strict safety procedures
must be applied.
Gland packing must not be used when pumping
hazardous liquids.
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.
ENSURE CORRECT LUBRICATION
(See section 5, Commissioning, startup, operation
and shutdown.)
START THE PUMP WITH OUTLET
VALVE PARTLY 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. The pump outlet control valve may
need to be adjusted to comply with the duty following
the run-up process. (See section 5, Commissioning
start-up, operation and shutdown.)
NEVER RUN THE PUMP DRY
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 pump and mechanical seal.
the motor and cause cavitations. Low flow rates may
cause a reduction in pump/bearing life, overheating of
the pump, instability and cavitation/vibration.
Products used in potentially explosive
1.6.4
atmospheres
Measures are required to:
Avoid excess temperature
Prevent build up of explosive mixtures
Prevent the generation of sparks
Prevent leakages
Maintain the pump to avoid hazard
The following instructions for pumps and pump units
when installed in potentially explosive atmospheres
must be followed to help ensure explosion protection.
For ATEX, both electrical and non-electrical
equipment must meet the requirements of European
Directive 94/9/EC. Always observe the regional legal
Ex requirements eg Ex electrical items outside the
EU may be required certified to other than ATEX eg
IECEx, UL.
1.6.4.1
Scope of compliance
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 ATEX pump set
shall select the coupling, driver and any additional
equipment, with the necessary CE Certificate/
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.
DO NOT 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 back pressure on the pump may overload

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 ºC (104 ºF); refer to
Flowserve for higher ambient temperatures.
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 and bearings and
due to the minimum permitted flow rate is taken into
account in the temperatures stated.
The operator is responsible to ensure that the
specified maximum liquid temperature is not
exceeded
Temperature classification “Tx” is used when the
liquid temperature varies and the pump could be
installed in different hazarous 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.
Where there is any risk of the pump being run
against a closed valve generating high liquid and
casing external surface temperatures, 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, make regular checks
and remove dirt from areas around close clearances,
bearing housings and motors.
1.6.4.4
Preventing the buildup of explosive
mixture
ENSURE THE PUMP IS PROPERLY FILLED
AND VENTED AND DOES NOT RUN DRY
Ensure the 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, fit an appropriate dry run protection device
(for example liquid detection or a power monitor).
To avoid potential hazards from fugitive emissions of
vapor or gas to atmosphere the surrounding area
must be well ventilated.
Page 7 of 76 flowserve.com
VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 – 10-13
Preventing sparks
1.6.4.5
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 base plate must be
properly grounded.
Avoid electrostatic charge: do not rub non-metallic
surfaces with a dry cloth; ensure cloth is damp.
For ATEX applications the coupling must be selected
to comply with 94/9/EC. Correct coupling alignment
must be maintained.
Additional requirement for metallic pumps on
non-metallic base plates
When metallic components are fitted on a nonmetallic base plate they must be individually earthed.
1.6.4.6
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, install a liquid detection device.
1.6.4.7
AVOID POTENTIAL HAZARDS WHICH GIVE A
RISK OF EXPLOSION
The responsibility for compliance with maintenance
instructions is with the plant operator.
To avoid potential explosion hazards during
maintenance, the tools, cleaning and painting
materials used must not give rise to sparking or
Preventing leakage
The pump must only be used to handle liquids
Maintenance to avoid the hazard
CORRECT MAINTENANCE IS REQUIRED TO
adversely affect the ambient conditions. 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.)

Instructions if required.
Noise Level
1.9
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.
Page 8 of 76 flowserve.com
VERTICAL TURBINE PUMPS (VTPS) CENTRIFUGAL PUMPS ENGLISH 71569224 – 10-13
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
at 1 m
pA
(3.3 ft) from the machine, for “free field conditions
over a reflecting plane”.
For estimating sound power level L
(re 1pW) then
WA
add 17 dBA to the sound pressure value.
The noise levels shown in table 1.9.1 are
extracted from typical motor manufacturer’s
data/catalogue to provide the average expected
motor noise values at no load for reference only and
are not guaranteed. The values could vary
depending upon the test and surrounding conditions.
The combined noise level of the pump and the motor
could exceed the values shown. It is to be noted that
adding motors with similar noise levels increases the
total noise level. Therefore, the dB correction to the
values listed above is required to obtain the
combined noise levels of motor and the pump.
Actual on-site noise measurement by experts is
recommended and safety measures are to be taken
accordingly.

Drivers
3.3.1
A variety of drivers may be used, however, electric
motors are most common. For the purposes of this
manual, all types of drivers can be grouped into two
categories.
a) Hollow shaft drivers: where the head shaft extends
through a tube in the center of the rotor and is
connected to the driver by a clutch assembly at the top
of the driver.
b) Solid shaft drivers: where the rotor shaft is solid
and projects below the driver-mounting base. This
type driver requires an adjustable coupling for
connecting to the pump.
Discharge Head Assembly
3.3.2
(See also section 3.2.2.1)
The discharge head supports the driver and bowl
assembly as well as supplying a discharge connection
in most cases.

A shaft sealing arrangement is located in the
discharge head to seal the shaft at its exit from the
liquid chamber.
The shaft seal will usually be either a mechanical
seal assembly or stuffing box with an open lineshaft
or a tube-packing box with an enclosed lineshaft.
Column assembly
3.3.3
The column assembly consists of column pipe, which
connects the bowl assembly to the discharge head
and carries the pumped fluid to the discharge head.
Houses and supports the shaft and may contain
bearings. Typical column assemblies are:
a) flanged column assembly
See sectional drawings supplied with the pump for
exact column assembly details as per the order. The
size and configuration vary depending upon the
specific order requirements and application criteria.
3.3.4
Bowl assemblies
The bowl assembly consists of impellers rigidly
mounted on the pump shaft coupled to an electric
motor. Impellers are cast wheels with multiple diffuser
vanes and are generally coated to meet the hydraulic
requirements. See section 8.0 for cross sectional and
part details.
Suction strainers
3.3.5
VTPs can also be fitted with strainers [316] to prevent
foreign particles from entering the pump. The type of
strainers and the mesh size depends on the
application. Examples are shown below. Strainers
are fastened [422] directly to the suction bell [55] or
attached using clips [421]. Cone shaped strainers
are provided with internal or external threads to

provision of correct foundation and installation may
lead to failure of the pump and, as such, would be
outside the terms of the warranty.
The foundation must consist of material that will afford
rigid support to the discharge head and will absorb
expected stresses that may be encountered in service.
Concrete foundations should have anchor bolts
installed in sleeves that allow alignment and have
holes in the mounting plate as illustrated in the detail
below. Sleeve should be filled with non-bonding
moldable material after sleeve is set in place.
When a suction barrel is supplied as in the case of the
type "TF" discharge head, the suction vessel must
provide permanent, rigid support for the pump and
motor.
All foundation / anchor bolt
recommendations should be verified by prevailing
industry standards.

Some wet pit pumps are installed directly by using
the flange that comes as an integral part of the
discharge head. The pump is lowered into the pit
and aligned with the anchor bolts [372].
The mounting flange is shimmed to achieve required
level by using a precision machinist’s level. The
pump is to be leveled to within 0.16 mm/m
(0.002 in./ft). The data to be recorded for future
reference. Anchor bolt nuts [373] are tightened
sufficient enough to hold down the pump in place.
Grout is poured and allowed to set for at least 72~80
hours (cure as required) before any further work is
done on the pump.
If leveling nuts are used to level the
base, they must be backed off as far as possible prior
to grouting.
Always shim near foundation bolts and then back off
the leveling nuts. Now tighten the foundation bolts. If
done otherwise there is a risk of significantly lowering
the structural natural frequency that could result in
separation of the base from the grout.
Directly mounted pumps are not user
friendly for service. Re-installation of these pumps
requires re-leveling and re-grouting.
Leveling of pumps mounted on a

soleplate and the soleplate is grouted
Some pumps are mounted on a separate plate
known as soleplate [23]. In such cases, the level
shall be set with a master level or a precision
machinist’s level. The mounting surface needs to be
leveled to within 0.16 mm/m (0.002 in./ft).
The level should not exceed 0.125 mm (0.005 in.)
elevation difference taken on any two points on the
individual soleplate. Accurate shimming and grouting
of the soleplate is very important. Record the leveling
data for future reference. Grout the soleplate and
allow to set at least 72~80 hours (cure as required)
before the pump is lowered into the pit. Align the
discharge head boltholes with the anchor bolts [372].
Check and adjust the pump level to within
0.16 mm/m (0.002 in./ft) with respect to the soleplate
and torque the nuts [373] to the required level.

flange mounting surface needs to be leveled to within
0.16 mm/m (0.002 in./ft) using shims and grouted.
Allow the grout to set for at least 72~80 hours before
the pump is installed. Check the barrel mounting
surface level after the grout is set and then proceed
with the pump installation. Lower the pump assembly
into the pit and align the discharge head flange bolt
holes to the anchor bolts [372].
Check and adjust the pump level with respect to the

Leveling of pumps with suction barrel
4.3.4
mounted on a soleplate
The soleplate [23] is installed on the foundation and
aligned with the anchor bolts [372]. Level the
soleplate with the help of a machinist’s level to within
0.16 mm/m (0.002 in./ft). Tighten the nuts [373] and
grout. Cure and allow grout to set for 72~80 hours.
Lower the suction barrel into the pit and level again
with respect to the soleplate [23] to within 0.16 mm/m
(0.002 in./ft). The level should not exceed 0.125 mm
(0.005 in.) elevation difference taken on any two
points on the soleplate. The pump [101] is now
lowered into the suction barrel and installed. Make
sure that the discharge head flange is still in level
within 0.16 mm/m (0.002 in./ft) with respect to the
suction barrel [315].

Where applicable, grout in the foundation bolts.
After adding pipe work connections and re-checking
the coupling alignment, the mounting plate/soleplate
should then be grouted in accordance with good
engineering practice. If in any doubt, please contact
Flowserve service center for advice.
Grouting provides solid contact between the pump
unit and foundation that prevents lateral movement of
running equipment and dampens resonant vibrations.
Care should be taken to ensure maximum surface
contact with grout between the pump base, sole
plate, suction can and foundation (no voids).
Foundation bolts should only be fully
tightened after the grout has been cured.
