explosion.
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.
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.
1.6.3 Safety action
This is a summary of conditions and actions to
help 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.
NEVER DO MAINTENANCE WORK
WHEN THE UNIT IS CONNECTED TO POWER
GUARDS MUST NOT BE REMOVED WHILE
THE UNIT IS OPERATIONAL
DRAIN THE UNIT AND ISOLATE
PIPEWORK BEFORE DISMANTLING THE UNIT
The appropriate safety precautions should be taken
where the pumped liquids are hazardous.
FLUORO-ELASTOMERS (When fitted.)
When a unit has experienced temperatures over
250 ºC (482 ºF), partial decomposition of fluoro-
elastomers (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.
THERMAL SHOCK
Rapid changes in the temperature of the liquid
within the unit 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 taken to avoid accidental contact. If complete
protection is not possible, the machine access must
Page 4 of 24 flowserve.com
USER INSTRUCTIONS T-SERIES THRUST BEARING POT ENGLISH 26999907 01-2013
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.
ENSURE CORRECT
LUBRICATION
(See section 5, Commissioning, startup, operation
and shutdown.)
1.6.4 Products used in potentially explosive
atmospheres
Measures are required to:
• Avoid excess temperature
• Prevent build up of explosive mixtures
• Prevent the generation of sparks
• Prevent leakages
• Maintain the unit to avoid hazard
The following instructions for 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 unit, the Ex rating applies only to the pump
unit. 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.
1.6.4.2 Marking
An example of ATEX equipment marking is shown
below. The actual classification of the pump unit
will be engraved on the nameplate.

Units 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 unit is influenced
by the temperature of the liquid handled. The

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 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 unit could be
installed in different hazarous atmospheres. In this
case the user is responsible for ensuring that the
unit 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 unit unfilled. Even a short
run time may give a high temperature resulting
from contact between rotating and stationary
components.
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 build up of explosive
mixtures
ENSURE THE UNIT IS PROPERLY FILLED
AND VENTED AND DOES NOT RUN DRY
It is essential to make sure that seal chambers,
auxiliary shaft seal systems and any heating and
cooling systems are properly filled.
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 baseplate 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 baseplates
When metallic components are fitted on a nonmetallic base they must be individually earthed.
1.6.4.6 Preventing leakage
Bursting of liquid containing parts due to freezing
must be avoided by draining or protecting the unit
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 Maintenance to avoid the hazard
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.
To avoid potential explosion hazards during
maintenance, the tools, cleaning and painting
materials used must not give rise to sparking or
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.)

3 DESCRIPTION
3.1 Configurations
These instructions cover only rolling element type
bearing thrust pots, without fan cooling, with
different rolling element bearing sizes available as
shown in the drawings. (See section 8.)
Thrust bearing pots are designed for vertical
centrifugal pumps driven by solid shaft electric
motor which have very limited capacity for taking
the pump vertical thrusts without a thrust bearing
pot fitted to the pump.
Installation is between the pump discharge head
and the motor/pump coupling. Sufficient room
should be provided between the pump discharge
head and the driver, normally by a driver stool, to
allow the necessary span for the installation of the
thrust bearing pot and the pump/motor coupling.
Pump hydraulic thrusts, producing energy, are not
transmitted to the pump foundation but are
converted into heat that is absorbed by the
lubrication oil for the bearings.
3.2 Name nomenclature
The thrust bearing pot size will be on the General
Arrangement drawing for the pump.
3.3 Design of major parts
3.3.1 Bearing housing
The bearing housing [3200] allows the installation
in the pump and takes the bearings themselves. It
acts as the sump for the lubrication oil for the
bearings and the larger sizes incorporate an
integral water cooling jacket that must be used to
allow adequate cooling of the bearings lubrication
oil where fitted with a cooling jacket. The bearing
housing incorporates ports to allow the internal

recirculation of the oil lubrication and includes an oil
level gage to check the lubricant oil level.
3.3.2 Bearings
The bearings [3010 and 3011] are hydrodynamic
rolling element type ball or roller bearings sized to
absorb the pump vertical thrust and pump rotor
weight from the centering sleeve [2470].
The thrust bearing [3010] absorbs the pump
hydraulic down thrust and the pump rotor weight.
The line bearing [3011] guides the rotating
components and absorbs the pump up-thrust
produced at start-up in most vertical pumps.
3.3.3 Centering sleeve
The centering sleeve [2470] connects mechanically
with an axial setting adjusting nut [2909], the pump
rotor and the bearings.
3.4 Performance and operating limits
3.4.1 Load capacity
Size Description
3.3.4 Bearing cover
The Bearing cover [3260] and upper bearing
housing [3210] provide sealing to the bearing
housing [3200] against the atmosphere.
It incorporates the oil filling connection and holds
the line bearing [3011] in position.
3.3.5 Thrust axial setting adjusting nut
The axial setting control adjusting nut [2909]
connects mechanically with the centering sleeve
[2470], the pump rotor and the bearings. This
allows control of the pump rotor axial regulation
play.
3.3.6 Accessories
Accessories may be fitted when specified.
Fan cooling is not available for these designs of

clothes.
Before working on the unit, take measures to
prevent an uncontrolled start. Put a warning board
on the starting device with the words:
"Machine under repair: do not start".
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 equipment with inflammable solvents
or carbon tetrachloride. Protect yourself against
toxic fumes when using cleaning agents.
6.2 Maintenance schedule
It is recommended that a maintenance plan
and schedule is adopted, in line with these User
Instructions, to include the following:
a) Any auxiliary systems installed must be
monitored, if necessary, to ensure they function
correctly.
b) Check for any leaks from gaskets and seals.
c) Check bearing lubricant level, and if the hours
run show a lubricant change is required.
d) Check vibration, noise level and surface
temperature at the bearings to confirm
satisfactory operation.
e) Check dirt and dust is removed from areas
around close clearances, bearing housings and
motors.
f) Check coupling alignment and re-align if
necessary.
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.
