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.
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
(Lock out.)
DRAIN THE PUMP AND ISOLATE PIPING
BEFORE DISMANTLING THE PUMP
The appropriate safety precautions should be taken
where the pumped liquids are hazardous.
FLUOROELASTOMERS (When fitted.)
When a pump has experienced temperatures over
250 °C (482 °F), 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.
NEVER OPERATE THE PUMP WITHOUT THE
COUPLING GUARD AND ALL OTHER SAFETY
DEVICES CORRECTLY INSTALLED
GUARDS MUST NOT BE REMOVED WHILE
THE PUMP IS OPERATIONAL
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.
HOT (and cold) PARTS
If hot or freezing components or auxiliary heating
equipment can present a danger to operators and
persons entering the immediate area, action must be
taken to avoid accidental contact (such as shielding).
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),
below 5 °C (20 °F) in a restricted zone, or exceeds
local regulations, action as above shall be taken.
Page 5 of 41
®
HAZARDOUS LIQUIDS
When the pump is handling hazardous liquids, care
must be taken to avoid exposure to the liquid by
appropriate pump placement, 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 6.2, Lubrication Data.)
NEVER EXCEED THE MAXIMUM
DESIGN PRESSURE (MDP) AT THE
TEMPERATURE SHOWN ON THE PUMP
NAMEPLATE
(See section 3.3, Performance and operating limits,
for pressure versus temperature ratings based on the
material of construction.)
NEVER OPERATE THE PUMP WITH
THE DISCHARGE VALVE CLOSED
(Unless otherwise instructed at a specific point in the
User Instructions.)
NEVER RUN THE PUMP DRY OR
WITHOUT PROPER PRIME (Casing flooded)
NEVER OPERATE THE PUMP WITH
THE SUCTION VALVE CLOSED
It should be fully opened when the pump is running.
NEVER OPERATE THE PUMP AT
ZERO FLOW OR FOR EXTENDED PERIODS
BELOW THE MINIMUM CONTINUOUS FLOW
THE PUMP SHAFT MUST TURN
CLOCKWISE WHEN VIEWED FROM THE
MOTOR END
It is absolutely essential that the rotation of the motor
be checked before installation of the coupling spacer
and starting the pump. Incorrect rotation of the pump
for even a short period can unscrew the impeller,
which can cause significant damage.
MPT USER INSTRUCTIONS ENGLISH 85392699 06-09
1.6.4 Products used in potentially explosive
atmospheres
Always check that the driver, drive coupling assembly
and pump equipment are suitably rated and/or
certified for the classification of the specific
atmosphere in which they are installed.
See section 9, Certification.
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.
Both electrical and non-electrical equipment must meet
the requirements of European Directive 94/9/EC.
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 pump set shall
select the coupling, driver, seal 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 effects in the motor. On
pump installations controlled by a VFD, the ATEX
Certification for the motor must state that it covers the
situation where electrical supply is from the VFD.
This particular requirement still applies even if the
VFD is in a safe area.

Pump liquid temperature
Pumps have a temperature class as stated in the ATEX
Ex rating on the nameplate. These are based on a
maximum ambient temperature of 40 °C (104 °F); refe r
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 applicable below. 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 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.
Do not attempt to check the direction of rotation with the
coupling element/pins fitted due to the risk of severe
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 temperature, 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 perform routine vibration monitoring.
In dirty or dusty environments, regular checks must
be made and dirt removed from areas around close
clearances, bearing housings, and motors.
Additional requirements for self-priming
casing pumps
Where the system operation does not ensure control of
priming, as defined in the User Instructions, and the
maximum permitted surface temperature of the T Class
could be exceeded, it is recommended that user install
an external surface temperature protection device.
1.6.4.4 Preventing the build up of explosive
mixtures
ENSURE PUMP IS PROPERLY FILLED AND
VENTED AND DOES NOT RUN DRY
Ensure that the pump and relevant suction and discharge
piping is totally filled with liquid at all times during the
pumps operation so that an explosive atmosphere is
prevented.
Page 7 of 41
MPT USER INSTRUCTIONS ENGLISH 85392699 06-09
®
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 can not avoid this
condition it is recommended that you 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.
1.6.4.5 Preventing sparks
To prevent a potential hazard from mechanical
contact, the coupling guard must be non-sparking for
Category 2.
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 the cloth is damp.
The coupling must be selected to comply with
94/9/EC and correct alignment must be maintained.
Additional requirements for pumps on
non-metallic baseplates
When metallic components are fitted on a nonmetallic baseplate they must be individually earthed.
1.6.4.6 Preventing leakage
1.6.4.7 Maintenance of the centrifugal pump to
avoid a 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.)
Pumps with mechanical seal. 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 auxiliary 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.

1.8 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, piping 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 LpA at 1 m
(3.3 ft) from the machine, for “free field conditions
over a reflecting plane”.
For estimating sound power level LWA (re 1pW) then
add 14 dBA to the sound pressure value.

2 TRANSPORT AND STORAGE
2.1 Consignment receipt and unpacking
Immediately after receipt of the equipment it must be
checked against the delivery/shipping documents for
its completeness and that there has been no
damage in transportation. Any shortage and/or
damage must be reported immediately to Flowserve
Pump Division and must be received in writing within
ten days of receipt of the equipment. Later claims
cannot be accepted.
Check any crate, boxes or wrappings for any
accessories or spare parts that 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
Boxes, crates, pallets, or cartons may be unloaded
using forklift vehicles or slings dependent on their
size and construction.
2.3 Lifting
Pumps and motors often have integral
lifting lugs or eye bolts. These are intended for use
in only lifting the individual piece of equipment.
Do not use eye bolts or cast-in lifting
lugs to lift pump, motor and baseplate assemblies.
To avoid distortion, the pump unit
should be lifted as shown.
Care must be taken to lift components
or assemblies above the center of gravity to prevent
the unit from flipping. This is especially true with
belt driven units with the motor mounted above the
pump.
2.3.1 Lifting pump components
2.3.1.1 Casing [1100]
Use either a sling or hook through each of the two
lifting lugs located on the side of the casing.
2.3.1.2 Bearing Housing [3200]
Insert an eye hook in the drilled and tapped hole at
the top of the bearing housing. Use either a sling or
hook through the eyebolt.
MPT USER INSTRUCTIONS ENGLISH 85392699 06-09
2.3.1.3 Power end
Same as bearing housing.
2.3.1.4 Bare pump
Use either a sling or hook through each of the two
lifting lugs located on the side of the casing and
around the outboard end of the bearing housing with
separate slings. Choker hitches must be used at both
attachment points and pulled tight. Make sure the
completion of the choker hitch on the bearing housing is
toward the coupling end of the pump shaft. The sling
lengths should be adjusted to balance the load before
attaching the lifting hook.
2.3.2 Lifting pump, motor and baseplate
assembly
To lift the pump, driver, and baseplate as a unit, the
following procedure must be followed.
V-belt guards should be removed if fitted.
• If the baseplate has lifting holes cut in the sides
at the end, insert lifting S hooks at the four
corners and use slings or chains to connect to a
lifting eye. Do not use slings through the lifting
holes.
• For other baseplates, sling around pump
discharge nozzle, when equipped, and the
outboard end of the motor frame using choker
hitches pulled tight.
• When pump is not equipped with optional
discharge nozzle, use user supplied eyebolt
screwed and seated into discharge of pump.
Insert lifting S hook in eyebolt and use sling.
2.4 Storage
Store the pump in a clean, dry
location away from vibration. Leave flange covers in
place to keep dirt and other foreign material out of
pump casing. Turn the pump shaft at regular
intervals to prevent brinelling of the bearings and the
seal faces, if fitted, from sticking.
Page 11 of 41
MPT USER INSTRUCTIONS ENGLISH 85392699 06-09
®
The pump may be stored as above for up to 6
months. Consult Flowserve for preservative actions
when a longer storage period is needed.
2.4.1 Storage – General
Normal packaging is designed to protect the pump
and parts during shipment and for dry, indoor
storage for up to six months or less. The following is
an overview of our normal packaging:
• All loose unmounted items are packaged in a
water proof plastic bag and placed under the
coupling guard
• Inner surfaces of the bearing housing, shaft (area
through bearing housing) and bearings are coated
with Cortec VCI-329 rust inhibitor, or equal.
Bearing housings are not filled with oil
prior to shipment
• The internal surfaces of ferrous casings, covers,
seal chamber, flange faces, and the impeller
surface are sprayed with Cortec VCI-389, or
equal
• Exposed shafts are taped with Polywrap
• Flange covers are secured to both the suction
and discharge flanges or face.
• In some cases with assemblies ordered with
external piping, components may be
disassembled for shipment
• The pump must be stored in a covered, dry
location
2.4.2 Storage – Long Term
Long term storage is defined as more than six
months, but less than 12 months. The procedure
Flowserve follows for long term storage of pumps is
given below. These procedures are in addition to
the short term procedure.
• Each assembly is hermetically (heat) sealed
from the atmosphere by means of tack wrap
sheeting and rubber bushings (mounting holes)
• Desiccant bags are placed inside the tack
wrapped packaging
• A solid wood box is used to cover the assembly
This packaging will provide protection for up to
twelve months from humidity, salt laden air, dust etc.
Warranty for the pumps will normally be for
12 months. Extension of this period can only be
achieved with the prior agreement of Flowserve
and would necessitate inspection prior to putting
the pump into service.
After unpacking, protection will be the responsibility of
the user. Addition of oil to the bearing housing will
remove the inhibitor. If units are to be idle for extended
periods after addition of lubricants, inhibitor oils should
be used. Every three months, the pump shaft should
be rotated approximately 10 revolutions.
2.5 Recycling and end of product life
At the end of the service life of the product or its parts,
the relevant materials and parts should be recycled or
disposed of using an environmentally acceptable
method and in accordance with local regulations. If the
product contains substances that are harmful to the
environment, these should be removed and disposed
of in accordance with current local regulations. This
also includes the liquids and/or gases that may be
used in the "seal system" or other utilities.
Make sure that hazardous substances are
disposed of safely and that the correct personal
protective equipment is used. The safety
specifications must be in accordance with the
current local regulations at all times.
3 DESCRIPTION
3.1 General
The Flowserve MPT single stage pump has a back
pull-out rotating assembly with suction and
discharge facings on the fixed casing to allow
removal of the rotating element without breaking the
pipe joints or moving the driver. Mounting feet are
rigidly connected to the casing so piping strains
allowed in section 2.3, Flange Loads, are readily
transmitted to the foundation.
No special tools are required for dismantling and
maintenance.
An example of the nameplate used on the MPT
pump, which is always mounted on the casing, is
shown below.

3.2 Design of major parts
3.2.1 Pump casing
The volute type casing with integral priming
chamber is of rugged heavy duty construction for
minimum wear under the toughest operating
conditions. Removal of the casing is not required
when performing maintenance of the rotating element.
The pump is designed with radial o-ring seals allowing
the rotating element and cover plate to be easily
removed (back pull out).
3.2.2 Valve flap
The pump suction opening is fitted with a non-return
flap valve. The flap is a solid one-piece design and
is easily removed for cleaning or replacement.
3.2.3 Impeller
A fully balanced semi-open two vane impeller is
spigotted and screwed to the shaft. The back of the
impeller has integrally cast clearing vanes.
3.2.4 Wear plate
The casing is fitted with a reversible and renewable
steel front wear plate which is a close clearance
against the impeller vanes. If the wear plate
becomes excessively worn, it can be reversed to
present its unworn face to the impeller. The Model
80 wear plate is not reversible.
3.2.5 Cover Plate
A large cover plate below the suction facing retained
by two hand nuts is easily removed to access the
impeller and wear plate for fast cleanout of clogged
or tangled solids.
A PRESSURE RELIEF VALVE IS FITTED TO
THE COVER PLATE AND MUST NOT BE
REMOVED, PLUGGED OR MODIFIED.
3.2.6 Shaft
The shaft is of ample size to transmit the maximum
power required and to minimize deflection and
vibration even during intermittent stop-start
operation. Keys are used to transmit the torque. The
shaft drive end and keyway are in accordance with
ANSI B17.1.
3.2.7 Stuffing box (Seal housing)
The seal housing is positively located, sealed and
fastened to the bearing housing and forms an oil
chamber in which the seal runs fully immersed. The
oil cools and lubricates the seal faces and prevents
seal damage if the pump is run dry. The oil level is
monitored via the sight glass fitted high on the
bearing housing allowing the pump to be shut down
in the event of a seal failure – indicated by a sudden
drop in oil level or product showing in the oil. A vent
is also fitted at the top of the housing to maintain
even atmospheric pressure in the oil chamber.
The seal housing is easily replaceable if wear from
the impeller back sealing vanes becomes excessive.
3.2.8 Shaft seal
The stuffing box is fitted with a double mechanical
seal; the pump end has a hard faced balanced
rotary unit to prevent liquid and grit entering the seal
chamber. The outboard end separates the seal and
bearing oil chambers.
3.2.9 Bearing housing
The robustly designed bearing housing is rigidly
bolted and sealed to the pump casing. The housing
is fitted with oil breather/fillers and sight glasses to
indicate fill and low oil levels. The end cover is fitted
with a lip seal to exclude dirt and moisture. An
eyebolt is fitted to the housing for back pull-out
withdrawal.
3.2.10 Pump bearings and lubrication
The pump is fitted with two different types of ball
bearings. The thrust bearing is a double row angular
contact ball bearing, and the radial bearing a single
row deep groove ball bearing. The thrust bearing is
fitted at the outboard end in all pumps except the
MODEL 80, which has it fitted at the inboard end.
Both bearings run in a common oil bath and are
sized for a long service life.
3.2.11 Impeller adjustment
The bearing housing (back pull-out assembly) is
fastened to the casing with four locknuts; these
locknuts pass through four adjustable spacers in the
bearing housing flange. Accurate impeller setting is
affected by adjustment of these spacer and locking
with the locknuts.
The correct adjustment is 0.38/0.25 mm
(0.015/0.010 in.) clearance between impeller vanes
and wear plate.
Clearance between the impeller and seal housing is
fixed and does not need adjustment.
3.2.12 Driver
The driver is normally an electric motor. Different
drive configurations may be fitted such as an
internal combustion engine, turbines, hydraulic
motors, etc driving via couplings, belts, gearboxes,
drive shafts, etc.
Page 13 of 41
MPT USER INSTRUCTIONS ENGLISH 85392699 06-09
®
If the driver is an internal combustion engine which
has not been supplied by Flowserve, a torsional
analysis must be undertaken by the supplier to
select the correct type of coupling in order to avoid
shaft failure.
3.2.13 Guards
Fabricated heavy duty sheet steel or aluminum solid
or vented guards are provided to suit customer
specific needs.
3.2.14 Baseplates
Standard baseplates are steel fabrications. Long
coupled and v-belt driven arrangement are
available. Horizontal driver alignment screws and
baseplate vertical leveling screws are provided as
an option. Special baseplates can be supplied to suit
individual installation needs.

3.3.6 Temperature limitations
3.3.6.1 Working temperature
The allowable pump working temperature range is
0 °C to +75 °C (32 °F to +167 °F).
3.3.6.2 Ambient temperature
These pumps are generally fitted with TEFC motors
with an ambient temperature limit of 0 °C to +40 °C
(32 °F to 104 °F). Specific pumps may be fitted wit h
motors to suit the client’s requirements with other
ambient temperature limits – see motor nameplate
for details.
4 INSTALLATION
4.1 Location
When selecting the location, be sure to install the
unit as close as practicable to the source of the
liquid to be pumped. Allow adequate space for
access, ventilation and maintenance operations
involving dismantling and inspection of parts.
Headroom is an important consideration as an
overhead lift of some type is required for installation
and maintenance of the pump-set.
4.2 Foundation
4.2.1 Install pump units
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.
4.2.2 Mount baseplate
The baseplate should be mounted onto a firm
foundation, either an appropriate thickness of
concrete or sturdy steel framework. It should NOT
be distorted or pulled down onto the surface of the
foundation, but should be supported to maintain the
original alignment. The location of the foundation
bolts and size of bolt holes can be obtained off the
General Arrangement Drawing (See section 8.7).
Page 15 of 41
MPT USER INSTRUCTIONS ENGLISH 85392699 06-09
®
Low vibration levels and long pump life will be
obtained when the foundations have an adequate
mass. Best practice requires the mass of the
foundation block to be five times the mass of the
equipment.
4.2.3 Install baseplate
Install the baseplate onto packing pieces (approx.
25 mm (0.984 in.) to 50 mm (1.969 in.)) evenly
spaced and adjacent to foundation bolts. Level the
baseplate to within 1 mm (0.039 in.) in every 3000
mm (118.11 in.) using a machinist’s level on the
machined surfaces of the pump and driver pads,
placing shims between baseplate and packing
pieces. The pump and driver have been aligned
before dispatch. Check alignment of pump and
motor half coupling. If this is incorrect, it indicates
that the baseplate has become twisted and should
be corrected by re-shimming.
4.3 Grouting
4.3.1 Grouting foundation bolts
Where applicable, grout in the foundation bolts.
4.3.2 Grouting baseplate
After adding pipe work connections and rechecking
the coupling alignment, the baseplate should then
be grouted in accordance with good engineering
practice. Fabricated steel and cast iron base plates
should be filled with grout. If in any doubt, please
contact your nearest Flowserve service center for
advice.
4.3.3 Grouting baseplate prevents movement
Grouting provides solid contact between the pump
unit and foundation, prevents lateral movement of
vibrating equipment, and dampens resonant
vibrations.
4.4 Initial alignment
4.4.1 Thermal expansion
The pump and motor will normally have to be
aligned at ambient temperature and should be
corrected to allow for thermal expansion at
operating temperature. In pump installations
involving high liquid temperatures, the unit should
be run at the actual operating temperature, shut
down, and the alignment checked immediately.
4.4.2 Alignment methods
4.4.2.1 Ensure the pump and motor half
couplings are disconnected.
4.4.2.2 The alignment MUST be checked.
Although the pump will have been aligned at the
factory, it is most likely that this alignment will have
been disturbed during transportation or handling.
Align the motor to the pump, not the pump to the
motor. Alignment is achieved by adding or
removing shims from under the motor feet and also
moving the motor horizontally as required. In some
cases where the alignment cannot be achieved, it
will be necessary to move the pump before
recommencing the above procedure.
4.4.2.3 For couplings with narrow flanges, use a
dial indicator gauge as shown.
The alignment values are maximal for continuous
service.

4.4.2.5 Measure face gap
Face gaps may be measured between the
machined faces using feeler gauges, measuring
wedge, calipers, or suitable micrometer.
4.5 Piping
4.5.1 Protective covers
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.
4.5.2 Forces and moments on pump flanges
Maximum forces and moments allowed on the
pump flanges vary with the pump size and type and
are shown in section 3.3.3, Flange Loads. To
minimize these forces and moments that may
cause misalignment, hot bearings, worn couplings,
vibration, and the possible failure of the pump
casing, the following points should be strictly
followed:
• Prevent excessive external pipe load
• Never draw piping into place by applying force
to pump flange connections
• Do not mount expansion joints so that their
force, due to internal pressure, acts on the
pump flange
4.5.3 Inlet pipe
The inlet pipe should be one or two sizes larger
than the pump inlet bore and pipe bends should be
as large a radius as possible. On suction lift the
piping should be inclined up towards the pump inlet
with long eccentric taper pipes incorporated to
prevent air locks. On positive suction, the inlet
piping must have a constant fall towards the pump.
4.5.4 Flow and pump suction
Flow should enter the pump suction with uniform
profile to minimize noise and wear. It is preferable
to have a straight length of suction pipe (approx. 8
to 10 times the pipe diameter) immediately
upstream of the suction nozzle and a straight
length of discharge pipe (approx. 5 to 8 times the
pipe diameter) immediately downstream of the
discharge nozzle.
Do not attach a short radius 90° bend directly on
the suction branch. A long radius suction bend may
be used as long as the bend is perpendicular to the
shaft center line of the unit. Do not install elbows at
an angle other than perpendicular to the shaft axis.
Elbows parallel to the shaft axis will cause uneven
flow into the impeller eyes.
Inlet strainers, when used, should have a net ‘free
area’ of at least three times the inlet pipe area and
a differential pressure device fitted to check for
blockage. Except in unusual circumstances,
strainers are not recommended in inlet piping. If
considerable foreign matter is expected, a screen
installed at the entrance to the wet well is
preferable.
4.5.5 Fitting valves and easy maintenance
Fitting an isolator and non-return valves can allow
easier maintenance. Never throttle pump on
suction side and never place a valve directly on the
pump inlet nozzle. If butterfly valves are used in the
suction line, the spindle must be parallel to the
pump shaft.
4.5.6 Piping and fittings should be flushed
before use.
4.5.7 Corrosive liquids
Piping for corrosive liquids should be arranged to
allow pump flushing before removal of a unit.
4.5.8 Air Release Valve
When a discharge check valve is applied an Air
Release Valve should be placed between the pump
discharge and the check valve. The Air Release
Valve’s function is to vent air from the pump during
the priming cycle. Flowserve Air Release Valves
are available.
4.6 Electrical Connections
4.6.1 Qualified electrician
Electrical connections should be
made by a qualified electrician in accordance with
the relevant local, national, and international
regulations.
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 any doubt, contact
Flowserve for advice.

5.2 Starting the pump
5.2.1 Start-up
Before initial start-up or start-up after a
prolonged period without operation, the rotating
element should be turned by hand to ensure it
rotates freely.
5.2.2 Priming plug
Remove priming plug [4610-3] from casing and
completely fill with water.
This operation is only necessary for the
initial start up. Pump will then remain primed.
5.2.3 Discharge line
When starting the pump, ensure that the discharge
line is empty. The use of valves in the discharge
line must be avoided to achieve correct priming.
If valves are to be fitted to the discharge
line, the specialized automatic air venting
equipment must be fitted to pump. Refer to
Flowserve.
5.2.4 Correct rotation
Priming accomplished, correct rotation established,
and with suction valve wide open, start the pump.
5.2.5 Check outlet pressure and flow.
5.2.6 Pressure
If NO pressure, or LOW pressure, STOP the pump.

(Section 7) for fault diagnosis.
5.2.7 Outlet valve
the pump has been fully primed and vented, it will
be unnecessary to re-vent or prime the pump.
5.3.1 Mechanical seals
5.3.1.1 Mechanical seals require no adjustment
5.3.1.2 Safeguard the inboard seal face
Before pumping dirty liquids, it is advisable, if
possible, to run the pump in using clean liquid to
safeguard the inboard seal face.
5.3.2 Stop/start frequency
Consult driver manual for maximum number of
starts per hour. STANDBY PUMPS SHOULD BE
RUN ALTERNATELY.
Any slight initial leakage will appear to stop when
the seal is run in. Seals will always have a slight
leakage in operation to lubricate the seal faces.
5.4 Stopping and shutdown
5.4.1 Close the outlet valve
If fitted, close the outlet valve but ensure that the
pump runs in this condition for no more than a few
seconds.
5.4.2 Stop the pump
5.4.3 Prolonged shutdowns
For prolonged shutdowns and especially
when ambient temperatures are likely to drop
below freezing point, close the suction valve and
drain the pump.
Do not run the pump with the outlet valve (if
fitted) closed for a period longer than 30 seconds.
5.2.8 Check the pump unit for vibration or
overheating.

6 MAINTENANCE
6.1 Maintenance schedule
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 if
required. This schedule is a recommendation only
and is intended to be amended by site experience
of the prevailing conditions. It outlines
recommendations for the pump only and must be
supplemented by schedules for other equipment on
the package.
6.1.1 Routine inspection (daily/weekly)
The following checks should be made and the
appropriate action taken to remedy any deviations:
• Check operating behavior. Ensure performance,
noise, vibration, and bearing temperatures are
normal
• Check that there is no abnormal fluid or
lubricant leakage
• Check running hours since last oil change.
Change if required
• Refer to the manuals of any associated
equipment for routine checks needed
• Check oil levels in seal chamber and bearing
housing
6.1.2 Periodic inspection (6 monthly)
• Check foundation bolts for security of
attachment and corrosion
• The coupling should be checked for correct
alignment and worn driving elements
• Check all paint or protective coatings
• Check all cable glands for tightness
• Refer to the manuals of any associated
equipment for periodic checks needed
6.2 Lubrication data
6.2.1 Oil lubricated bearings and
mechanical seals
Normal intervals between oil changes are 4000
operating hours or a 12-month period. The
characteristics of the installation and severity of
service will determine the frequency of lubrication
change. See Section 3.3.4, Pump lubricant data.
Any sudden change in oil level should be
investigated without delay. A rise in bearing
housing oil level, together with a drop in the seal
chamber oil level, indicates a secondary seal failure
allowing oil leakage from the seal chamber to the
bearing housing. A drop in bearing housing oil level
indicates an external leak and a check of the pump
would show the source as a failure of the bearing
cover lip seal or gasket or a loose drain plug. An
abnormal rise or fall in the seal chamber oil level
with no change in the bearing housing oil level
indicates a primary seal failure with product leaking
into seal chamber or oil leaking into the pump.
Always use the recommended Type and
grade of oil, Mobil DTE Medium or Castrol Hyspin
AWS 46. Never mix oil types.
6.3 Mechanical seals
When leakage becomes unacceptable as
determined above, the seal will need to be repaired
or replaced.
6.4 Dismantling
6.4.1 General
Cleanliness is extremely important and care
must be taken to prevent any foreign material from
entering the pump or its components.
This pump is of the back pull-out design; it is not
necessary to remove the casing, to detach the
suction and delivery piping, or to remove the driver
to dismantle pump.
6.4.2 Dismantling the pump
Refer to Safety section before dismantling
the pump.
6.4.3 Genuine Flowserve parts

• Press or drive shaft, complete with bearings,
from bearing housing in the direction of the
coupling end of the shaft
• Remove the drive end bearing circlip [6544]
from the shaft. Note that the circlip is fitted to all
size pumps except the MODEL 80. Remove the
bearings from the shaft using a suitable bearing
puller applying pressure to the inner race only to
avoid damaging the bearings or shaft. Bearings
SHOULD NOT be refitted, but if it is intended to
reuse them, they should be wrapped in plastic
ready for washing and inspection
6.4.6.5 Removal of Wear Plate
Remove handnuts [6580-1] and withdraw
coverplate [1223-0]. Remove hexagon setscrews
[6570-1] and separate wear plate from cover. Note

6.5 Examination of parts
6.5.1 Used parts
Used parts must be inspected before assembly to
ensure the pump will subsequently run properly. In
particular, fault diagnosis is essential to enhance
pump and plant reliability.
6.5.2 Casing, impeller, wear plate, and seal
housing
Inspect for excessive wear, pitting, corrosion,
erosion, or damage and any sealing surface
irregularities. The wear plate on all pump sizes can
be re-machined to restore its wearing face and on

and impeller setscrew for erosion damage.
6.5.4 Gaskets, O-rings, and lip seals
After dismantling, discard and replace.
21 of 41
MPT USER INSTRUCTIONS ENGLISH 85392699 06-09
®
6.5.5 Bearings
Bearings generally MUST NOT BE reused after
removal from any shaft; however, due to the small
interference fit of the bearings in these pumps, if
they are removed carefully by pulling on the inner
ring only without the use of heat and if thorough
cleaning and inspection shows them fit for further
service, they may be reused. It is strongly
recommended, however, that they be replaced as a
matter of course. Thoroughly clean the inside of
the bearing housing, bearing cover, and seal
housing, removing any sign of contamination or
rust and dry out with lint-free cloths or dry air.
6.5.6 Suction flange and flap valve
Check the valve seating on the suction flange for
erosion damage and the flap valve for deterioration
of the neoprene sealing surface and replace if
necessary.
6.5.7 Mechanical seal
Carefully inspect seal faces for cracks, chips, or
scoring and O-rings for any obvious damage. If in
doubt either replace or return seal to Flowserve
service center for inspection.
6.6 Assembly
6.6.1 To assemble the pump consult the
sectional drawings.
6.6.2 Prepare
Ensure all parts are on hand; clean and fit for
further service. Pay particular attention to threads
and gasket and O-ring sealing faces. Lightly apply
anti-seize compound to all threads and close fitting
surfaces. Do not unwrap bearings and seals or
expose the bearing housing and seal chamber
inner surfaces until time to fit. Immediately prior to
assembly, wipe clean with lint-free cloth.
6.6.3 Bearings
• Carefully press the bearings onto the shaft,
applying load to inner ring only; ensure bearings
are pushed hard up against the location
shoulder on the shaft. It is not necessary to use
heat to fit MPT bearings as only light press fits
are involved. If desired, bearings can be heated
to approx. 100 °C (212 °F) with an induction
heater, but under no circumstances use a flame
on the bearings. Fit the circlip [6544] to the shaft
at the outboard bearing [3041]. Note that a
circlip is fitted on all pump sizes except the
MODEL 80
• Support shaft/bearing assembly on clean vee
blocks under the bearings and check shaft
runout at coupling end and mechanical seal
area. Runout is not to exceed 0.05 mm (0.002
in.) TIR
• Push shaft/bearing assembly into bearing
housing from drive end, ensuring that thrust
bearing bottoms against shoulder in bearing
housing and that shaft rotates freely
• Fit new lip seal [4300] into bearing cover [3260].
Note orientation of lip seal (spring loaded lip
faces toward coupling)
• Fit new gasket at bearing housing face and refit
cover; ensure that seal lip is lightly oiled and
care is taken easing it over shaft shoulder. Refit
and tighten cover fasteners. Check that shaft
rotates freely
6.6.4 Mechanical seal
• Fit mechanical stationary face holder in recess
at inboard end of bearing cover and fit
stationary face. Take extreme care to keep face
clean and prevent damage. Lightly oil seal
rotating assembly and carefully slide over shaft
to seat against stationary
• Fit inboard stationary face holder in recess in
seal chamber and carefully fit stationary face
• Fit new O-ring to recess in bearing housing
joint, fit seal chamber over end of shaft, and
locate on bearing housing spigot. Refit and
tighten fasteners
6.6.5 Impeller
• Lightly coat shaft and impeller threads with antiseize. Preventing shaft from rotating, screw
impeller onto shaft and bottom firmly against
shaft shoulder. Fit and tighten impeller setscrew
[2913] complete with washer [2905-0]
• Check impeller to seal housing axial clearance,
which should be within the range 0.05/1.35 mm
(0.002/ 0.053 in.) on a new assembly
6.6.6 Suction flange
• Refit valve flap to suction flange with check
valve pin [6570-4] and nylon washer [2905-1]
• Fit suction flange to casing with new gasket
[4510-1]
6.6.7 Coverplate/wear plate
• Refit new, re-machined, or reversed wear plate
[1915] to the cover plate [1223-0]
• Fit new O-ring [4610-2] to cover and lightly oil
• Fit cover into casing and retain with hand nuts
[6580-1]
22 of 41
MPT USER INSTRUCTIONS ENGLISH 85392699 06-09
®
6.6.8 Back pull-out assembly/case
• Fit new O-ring [4610-0] to bearing housing
spigot and lightly oil
• Ensure that spacing bushes [1680] are screwed
fully home in bearing housing flange. This will
give maximum impeller clearance on assembly
• Sling from eyebolt [1020] and fit back pull-out
assembly into casing, taking care not to damage
machined casing bores and O-ring. Tighten
fasteners finger tight only
• Back off stud nuts [6580-1] and spacing bushes
in turn by equal amounts, at the same time
pushing back pull-out assembly into casing until
impeller contacts wear plate. At this stage check
the gap between the bearing housing and case
at four places to ensure that assembly is fully
seated on wear plate
• To obtain correct clearance at wear plate turn
spacing bushes each one flat in a clockwise
direction. This will give a clearance of 0.30 mm
(0.012 in.) and the nuts [6580-1] can now be
fully tightened
6.6.9 Lubrication
Ensure oil chamber drain plugs are tightly fitted,
remove air vents [3854] from bearing housing and
seal chamber, and fill both chambers to the correct
level on the sight glasses [3858] with Mobil DTE
Medium or Castrol Hyspin AWS 46 oil.
Approximately one liter (33.81 fl. oz.) of oil in seal
chamber and 350 ml (11.83 fl. oz.) in the bearing
housing are needed. Refit vents and check for
leaks. Now that seals are lubricated, check element
for free rotation.
6.6.10 Final assembly
• Refit coupling and connect driver. Check driver
alignment
• Refit guards
• Refit suction and discharge piping with new
gaskets
• Check all fasteners and plugs for tightness
