1.6 Safety

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 would affect
personal safety.

This symbol indicates safety instructions where

non-compliance would affect personal safety.

This symbol indicates safety instructions where

non-compliance would affect protection of a safe life
environment.

This symbol indicates safety instructions
where non-compliance would affect the safe operation or
protection of the pump or pump unit.

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.

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
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.)

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 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. 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 seal.

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 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.

NEVER DO MAINTENANCE WORK

WHEN THE UNIT IS CONNECTED TO POWER

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.

DRAIN THE PUMP AND ISOLATE PIPEWORK
BEFORE DISMANTLING THE PUMP
The appropriate safety precautions should be taken
where the pumped liquids are hazardous.

Page 5 of 54

MJ SLURRY USER INSTRUCTIONS ENGLISH 71569294 - 02/08

®

FLUORO-ELASTOMERS (When fitted.)
When a pump has experienced temperatures over 250
ºC (482 ºF), partial decomposition of fluoro-elastomers
(e.g. 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.

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 vapour could cause an explosion.

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.

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 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 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 will be
engraved on the nameplate.

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 °C (104 °F); refer to Flowserve
for higher ambient temperatures.

The temperature of the liquid handled influences the
surface temperature on the pump. 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.

400 °C (752 °F) *

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 when the pump is required to be
used in differently classified potentially explosive
atmospheres. In this case the user is responsible for
ensuring that the pump surface temperature does not
exceed that permitted in its actual installed location.

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 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

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 the fitting of an appropriate dry run protection
device is recommended (eg liquid detection or a power
monitor).

To avoid potential hazards from fugitive emissions of
vapour 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 and
anti-static for Category 2.

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

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

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

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

Page 7 of 54

MJ SLURRY USER INSTRUCTIONS ENGLISH 71569294 - 02/08

®

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

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.

1.7 Nameplate and warning labels

1.7.1 Nameplate

For details of nameplate, see the Declaration of Conformity.

1.7.2 Warning labels

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.)

1.8 Specific machine performance

For performance parameters see section 1.5, Duty
conditions. When the contract requirement specifies

these to be incorporated into User Instructions these
are included here. Where performance data has been
supplied separately to the purchaser these should be
obtained and retained with these User Instructions if
required.

1.9 Noise level

When pump noise level exceeds 85 dBA attention must
be given to prevailing Health and Safety Legislation, to
limit the exposure of plant operating personnel to the
noise. The usual approach is to control 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
machines above a certain power level will exceed 85
dBA. In such situations consideration must be given to
the fitting of an acoustic enclosure to meet local
regulations.

Pump noise level is dependent on a number of factors ­the type of motor fitted, the operating capacity,
pipework design and acoustic characteristics of the
building. The levels specified in the table below are
estimated and not guaranteed.

The dBA values are based on the noisiest ungeared
electric motors that are likely to be encountered. They
are Sound Pressure levels at 1 m (3.3 ft) from the
directly driven pump, for "free field over a reflecting
plane". For estimating L
add 14dBA to the sound pressure value.

If a pump unit only has been purchased, for fitting with
your own driver, then the "pump only" noise levels from
the table should be combined with the level for the
driver obtained from the supplier. If the motor is driven
by an inverter, it may show an increase in noise level at
some speeds. Consult a Noise Specialist for the
combined calculation.

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 one month 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.

The pump should be lifted with suitably sized and
located slings. Do not use the shaft for lifting and take
special care to prevent the pump from rotating in the
slings due to unbalanced weight distribution.

2.3 Lifting

A crane must be used for all pump sets in excess
of 25 kg (55 lb). Fully trained personnel must carry out
lifting, in accordance with local regulations. The driver
and pump weights are recorded on their respective
nameplates or massplates.

2.4 Storage

2.4.1 Short-Term Storage

When it is necessary to store a pump for a short time
before it can be installed, place it in a dry, cool location.
Protect it thoroughly from moisture and condensation.
Protective flange covers should not be removed until
the pump is being installed.

Wrap the exposed portions of the shaft and coupling to
protect against sand, grit or other foreign matter. Oil
lubricated units should be lubricated (refer to Section
III) to protect the bearings. Grease lubricated units are
lubricated at the factory during assembly. Turn the

rotor over by hand at least once a week to maintain a
protective film on the bearing components.

2.4.2 LONG-TERM STORAGE

More than precautions are required if long-term storage
in excess of 90 days from factory shipment is
unavoidable.

The internal surfaces of the pump should be sprayed
with a rust preventative such as water-soluble oil or
other suitable alternative. Particular attention should
be given to the impeller, wear plate and stuffing box.

An optional method of protection is to suspend bags of
desiccant material inside casing and completely seal all
openings from the surrounding atmosphere. The
stuffing box should be packed with clean. dry rags.
Use of this method requires that the casing be initially
free of liquid. The desiccant material should be
checked at regular intervals to ensure that it has not
absorbed excessive water vapour. A warning
instruction, advising that the desiccant must be
removed prior to installation should be wired to the
pump.

A rust inhibitor should be added to the lubricating oil of
oil lubricated units to give additional protection without
destroying the lubricating properties of the oil. For
specific recommendations, consult your lubrication
dealer. Grease lubricated units, which can be identified
by the grease fitting at each bearing location, should be
well lubricated prior to placing in storage. Small
amounts of additional grease should be added at
regular intervals during storage. Refer to Section III for
additional information related to grease lubrication.

Storage of pumps in areas of high ambient vibration
should be avoided to prevent bearing damage due to
brinelling. The risk of such damage can be reduced by
frequent rotation of the shaft.

The pump half coupling and key should be removed
from the shaft, coated with rust preventative and
wrapped to prevent metal-to-metal contact. Exposed
surfaces of the pump shaft should be protected with a
rust preventative. All dismantled parts should be
wrapped and tagged according to pump serial number
and a record kept of their location.

Pumps covered with plastic should
not be stored in a cool environment because
resulting condensation can cause rusting.

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

3 PUMP DESCRIPTION

3.1 Configurations

Flowserve "MJ Slurry" pumps are single stage, vertical
bottom suction centrifugal pumps specifically designed
for handling abrasive slurries typical of mining and
mineral process. A semi-concentric volute type casing
is pedestal mounted with tangential discharge nozzle.
The closed impeller with rear pump-out vanes is
capable of passing solids of various sizes. The rigid
three point thrust bearing housing support permits
precision bearing alignment. The casing is supported
from the top plate by column pipe(s).

The pump has a water lubricated steady bearing
located in a lower housing located above the impeller.
Intermediate steady bearings will be supplied to
maintain shaft critical speeds are above the operating
speeds.

Pumps can be v-belt driven or direct driven by an
electric motor. The bearing frame design varies
according to the drive method.

All pumps are carefully inspected and prepared for
shipment. All exterior machined surfaces are coated
with a rust preventative compound and openings are
provided with covers or plugs. The axial impeller
running clearance is preset at the factory but should be
checked prior to final alignment in case of tampering.

3.2 Name nomenclature

3.3 Design of major part s

3.3.1 Pump casing

The pump casing is a semi-concentric volute type
casing and tangential discharge nozzle. The casing is
pedestal mounted therefore the discharge can be
rotated to meet a number of optional orientations. On
standard duty casing the suction nozzle is integral to
the casing. On severe duty pumps the pump uses a
removable suction cover. The casing joints are
gasketed connections.

3.3.2 Impeller

The impeller is closed design as standard but may be
changed to open designs for mud, froth and viscous
applications. The impeller is thread mounted to the
shaft. All impellers are supplied with pump out vanes to
minimise wear and reduce pressure at the stuffing box.
The vanes are curved to optimize efficiency however,
the “S” configuration utilizes straight radial vanes to
reduce blockage. The impeller of the MS pump has
larger front clearances to reduce shear and improve
froth handling capabilities.

3.3.3 Shaft

The large diameter stiff shaft, mounted on bearings,
has a keyed drive end.

3.3.4 Pump bearings and lubrication

Ball bearings are fitted as standard above the top plate
and grease lubricated. Pumps that are direct driven
have a set of angular contact ball bearings mounted
back-to-back. Pumps that are MVD driven have 2 sets
the bearings. The lower bearing, located just above the
mounting plate is a deep groove ball bearing. A set of
angular contact ball bearings is located towards the
sheave. All bearings located below the top plate are
water lubricated. These are generally cutlass rubber

Page 12 of 54

MJ SLURRY USER INSTRUCTIONS ENGLISH 71569294 - 02/08

®

bearings contained in a stainless sleeve and mounted
in a bearing housing. Intermediate bearings are located
to ensure shaft critical speeds are above the operating
speed.

3.3.5 Bearing housing

Grease nipples enable grease-lubricated bearings to be
replenished between major service intervals.

3.3.6 Lower and Intermediate bearing housing

The bearing housings below the top plate have a spigot
(rabbet) fit between the pump casing and column pipe
or between column pipes for optimum concentricity.

3.3.7 Driver

The driver is normally an electric motor. Due to the
hardness of the impeller the norm is to use multi-v­belts.

3.3.8 Accessories

Accessories may be fitted when specified by the
customer.

3.4 Performance and operating limits

This product has been selected to meet the
specifications of your purchase order see section 1.5.
The following data is included as additional information
to help with your installation. It is typical, and factors
such as temperature, materials, and seal type may
influence this data. If required, a definitive statement
for your particular application can be obtained from
Flowserve.

3.4.1 Operating limits

Pumped liquid temperature limits up to +66 ºC (150 ºF)
Maximum ambient temperature up to +50 ºC (122 ºF)
Maximum soft solids in suspension up to 7 % by volume
Maximum pump speed Refer to the nameplate
Maximum Water Flush temperature up to +38 ºC (100 ºF)

3.4.2 Speed torque curves

To bring a centrifugal pump up to rated speed, the
driver must be capable of providing more torque at
each speed than required by the pump. The margin
between the available and required torque affects the
time it takes the unit to reach full speed. If the torque
required by the pump exceeds the torque capability of
the drive at any run-up speed, the unit will not
accelerate to full speed. Normally, this is not a problem
with standard induction or synchronous motors
provided the proper voltage is supplied at the motor.

For pumps started at shut valve conditions, 100 percent
full speed torque can be calculated by using the
formula:

Torque (Nm) = 9545 Shutoff Power (kW)
r/min

Torque (lbfx ft) = 5250 Shutoff Power (hp)
r/min

Torque required by the pump at any other speed during
start-up can be determined from the curve above. Note
that the driver manufacturer usually bases 100 percent
torque on the design power of the driver and
consequently the speed-torque curves should be
plotted in torque units (e.g. Nm) instead of percentage
torque to avoid confusion.

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.

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.
Allow sufficient room to facilitate the back pull-out
feature on V-belt driven units.

Refer to the general arrangement drawing for the
pump set.

4.2 Part assemblies

Motors may be supplied loose on M Slurry pumps,
typically on frame sizes 400 and above. It is the
responsibility of the installer to ensure that the motor
is assembled to the pump and lined up as detailed in
section 4.5.2.

4.3 Foundation

The foundation may consist of any
material that will afford permanent, rigid support to
the top plate. It should be of sufficient size and mass
to absorb expected strains and shocks that may be
encountered in service. The sump opening must be

MATERIAL

CLASS

STEEL

large enough to pass the pump liquid end and
discharge piping. The top surface must be flat and
level for future pump alignment.

In the cases where maximum support is desired or
where levelling problems are anticipated a sole plate
(as illustrated in Figure 1) may be used as the
bearing surface for the top plate. A sole plate is
sometimes referred to as a curb ring. When a sole
plate is used it should be bolted to the concrete
foundation and grouted into position.

Foundation bolts should be high strength steel (SAE
GR 5 or equal). Each bolt should be surrounded by a
pipe sleeve two or three times the diameter of the
bolt. The sleeve should be securely anchored and
designed to allow the bolts to be moved to align with
holes in the top plate or sole plate as required. The
bolts should be sufficiently long to allow for leveling
shims or wedges. Extra long bolts can be shortened
after the installation is complete.

4.3.1 Sole Plate Installation.

Position the sole plate next to the foundation and
clean the foundation surface thoroughly. Remove the
rag packing from the pipe sleeve and place wedges
or shims as close to the foundation bolts as possible.
Leveling nuts may be used on the bolts instead of
wedges.

Sole plates are normally not supplied by Flowserve.

Page 15 of 42

MJ SLURRY USER INSTRUCTIONS ENGLISH 71569294 - 02/08

®

4.4 Baseplate installation

Position the pump next to the foundation and clean the
foundation surface thoroughly. Remove the rag packing
from the pipe sleeves and place wedges or ships as
close to the foundation bolts as possible. These may be
omitted if a jacking nut on the foundation anchor bolts is
preferred for levelling. Initial levelling should be within

0.75 mm (.030 inches).

Remove the flange covers and check inside the pump
nozzles for cleanliness. Kerosene is recommended as
the best solvent for removing factory applied rust
preventative. Ensure that all traces of rust preventative
are removed from the discharge and suction flange
faces, the exposed shafting and all coupling surfaces.
Flush the pump internals of any rust preventative
applied for long-term storage.

Figure 1

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.

4.5.2 Alignment methods

Lift the baseplate assembly, remove the shipping skids
and clean the underside of the baseplate. Position the
baseplate over the foundation and lower the unit over
the foundation bolts and onto the wedges, shims or
jacking nuts.

With the aid of a machinist's level, adjust the wedges,
shims or jacking nuts to level the pump and driver
mounting pads in each direction. Check to ensure that
the suction and discharge flanges are plumb, level, and
at the correct elevation. It is normal practice to set the
mounting pads slightly low in order to permit lowering of
units which may be required to suit future piping or
minor changes. Place washers over the foundation
bolts and install nuts. Tighten finger tight only.

Check the impeller axial clearance and that the rotor
turns freely by hand.

Note: Grout is not poured until an initial alignment
of the pump and driver has been performed.

4.5 Initial alignment

4.5.1 Thermal expansion

The pump and motor will normally
have to be aligned at ambient temperature and

Ensure pump and driver are isolated

electrically and the half couplings are disconnected.

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. If
necessary, align the motor to the pump, not the pump
to the motor.

4.5.2.1 Direct Driven Units:

The importance of accurate alignment of pump and
driver shafts cannot be overemphasized.

IMPROPER ALIGNMENT IS THE PRIMARY CAUSE
OF VIBRATION PROBLEMS AND REDUCED
BEARING LIFE.

A flexible coupling is used to compensate for slight
changes in alignment that occur during normal
operation and is not used to correct for installation
errors. Install the pump and driver half couplings in
accordance with the coupling manufacturer's
instructions. Note that the coupling hub faces are not
always mounted flush with the ends of the shafts.
Place the driver on the topplate such and ensure that
motor shaft and pump shaft are spaced apart by at
least 3mm (0.12”).

The purpose of the alignment procedure is to ensure

Page 16 of 42

MJ SLURRY USER INSTRUCTIONS ENGLISH 71569294 - 02/08

®

that the pump and driver shafts are in parallel and
angular alignment under the normal operating
conditions of load and temperature

.

When the pump coupling and driver are assembled
at the factory, the units are aligned prior to shipment.
For pumps and drivers that operate at different
temperatures compensation must be made at the
initial alignment stage (when the units are at the
same temperature) to allow for thermal expansion
during operation. Consult the instruction manual
supplied with the driver for the manufacturer's
recommendations.

Shaft alignment is greatly simplified by the use of a
dial indicator with extension rods and a magnetic
base. Before taking readings, ensure that the pump
and driver mounting bolts are secure, and that the
thrust bearing housing is properly aligned in the
bearing frame or cartridge.

Parallel Alignment:

Mount the magnetic base on the pump half coupling
hub, either the face or O.D. as shown in the sketch.
Place the dial indicator button on the outside diameter
of the driver half coupling hub.

The length of extension rods should be kept at

a minimum to reduce deflection.

Rotate the pump shaft and record the dial reading at the
top, bottom and each side. Correct the parallel
alignment by adding or removing shims under the driver
and/or moving the driver horizontally. Repeat this
procedure until the maximum total indicator reading
(T.I.R.) is within 0.076 mm (0.003 inch.)

Angular Alignment:

Mount the magnetic base on the pump half coupling
hub, either the face or O.D. as shown in the sketch.
Move the dial indicator button to indicate on the face of
the driver half coupling hub as close to the outside
diameter as possible. When convenient the indicator

can be placed on the inside face to keep spans short.
Turn both shafts 360° and record the dial readings at
90° intervals. Adjust the shims under the motor as
required and repeat the procedure until the angular
alignment is within 0.0005 mm (T.I.R.) per mm (0.0005
inch per inch) of maximum hub diameter.

Repeat the checks on parallel and angular alignment,
ensuring the mounting bolts are secure, until the unit is
properly aligned. Note that correction in one direction
may affect the alignment in another direction. Re-check
the gap between the coupling hubs.

If any difficulty is encountered in achieving the
recommended alignment tolerances, the runout of the
pump and driver shafts and each coupling hub diameter
and face should be checked. Occasionally, due to
practical and unavoidable manufacturing tolerance
build-up associate with the pump, coupling and driver, it
may be necessary to match up the two coupling hubs in
the most advantageous relative angular position in order
to achieve an acceptable alignment.

Do not connect the couplings alignment is re-checked.

Complete piping as below and see sections 4.7, Final

shaft alignment check up to and including section 5,
Commissioning, startup, operation and shutdown

before connecting driver and checking actual
rotation.

4.5.2.2 V-belt Drive Units:

Check that both sheaves are free of grease, rust, nicks
or burrs. Install the correct size sheave on the pump
shaft and locate the sheave axially to minimize
overhang. Re-check the impeller axial clearance and
ensure that the pump is properly secured to the
baseplate. Install the driver on the adjustable base
provided and install the driver sheave in line with the
pump sheave. Ensure that the sheaves are tight on the
shafts. With a dial indicator, check the runout on the
periphery and face of each sheave to ensure that each
is running true. Tighten the adjustable base and check
that the driver rotation in the correct direction and that
vibration levels are not unacceptable.

Before starting the driver, refer to the

manufacturer’s instruction manual. The correct rotation
of the pump shaft is marked on the pump casing or
frame.

Check that all belts making up one drive set have
matched code numbers. Loosen the adjustable base
and install the belts in their proper grooves. Adjust the
center distance between the sheaves to obtain proper
belt tension. Check the alignment of the pump and
driver sheaves with a taught string or straight edge. For
proper alignment and the sheave faces must be parallel
to each other and in line. Adjustments are made by
slackening the belts and moving the sheaves. Retighten
the drive or driver sheave then recheck. The procedure
may need to be repeated to get alignment as close as
possible.

When the sheaves are aligned that the shafts rotate
freely by hand and install safety guard.

V-belts that are too loose will cause excessive belt
wear or breakage.

V-belts are too tight will cause excessive loading on
the pump and motor bearings and could cause
overheating or reduced bearing lives.

 Additional information is available from the

sheave and belt supplier.
The motor drive for sheave driven pumps is
frequently bolted to a motor support which is
constructed of fabricated steel. There are normally 4
adjustment bolts to alter the center distance between
the sheaves.

The adjustment procedure is as follows:

a) Release the lock bolts on each side of the motor

stand.

b) Release the locking nuts on the 4 jacking bolts. (2

on each bolt).
c) Turn the jacking bolts to move the motor out or in.
d) To install or remove belts it may be necessary to

move the motor 25mm (1”) towards the pump

frame.
e) Move the motor away from the pump frame to

tighten the belt tension.
f) Recheck the face of the sheaves and to ensure

that the faces are flat and in-line.
g) Lock the jacking bolts in place with the lock nuts.
h) Tighten the lock bolts on the side of the motor

mount.
i) Rotate the sheaves by hand to ensure that the

pump impeller is free to move.
j) Install the sheave/belt guard.

Maintaining V-belt tension is the most

important rule of v-belt care.

4.6 Grouting

The purpose of grouting is to provide rigid support to the
pump and driver by increasing the structural rigidity of
the top plate and making it an integral mass with the
foundation.

Clean the roughed foundation surface and build a
wooden form around the soleplate (see Fig. 1). For
initial grouting forms should be placed to isolate shims
and levelling nuts. The foundation surface should be
thoroughly saturated with water before grouting. A
typical mixture for grouting-in a pump base is composed
of one part pure Portland cement and two parts of clean
building sand with sufficient water to provide the proper
consistency. The grout should flow freely but not be so
wet as to cause the sand and cement to separate.

Thoroughly puddle the grout while pouring to eliminate
air pockets and low spots. Pour sufficient grouting to
ensure that the bottom surface of the soleplate is
completely submerged. Do not fill isolated areas
around the shims or levelling nuts. Once the grout has
set sufficiently, remove the wooden forms and finish off
the sides and top as desired. At the same time,
roughen the grout surface inside the soleplate. Cover
with wet burlap and allow the grout to cure for at least
40 hours.

After grouting has cured, shims and levelling nuts
should be removed or backed off. Tighten down
soleplate to the new grout to put bolts in tension and
ensure rigidity of structure. Install jam nuts and cut the
bolts to the desired length. Finish grouting isolated
areas.

4.7 Piping

4.7.1 Suction and discharge pipework

In order to minimize friction losses and hydraulic
noise in the pipework it is good practice to choose
pipework that is one or two sizes larger than the
pump suction and discharge. Typically main
pipework velocities should not exceed 2 m/s (6 ft/sec)
suction and 3 m/s (9 ft/sec) on the discharge.

Take into account the available NPSH, which must
be higher than the required NPSH of the pump.

Never use the pump as a support for

piping.

Maximum forces and moments allowed on the pump
flanges vary with the pump size and type. To
minimize these forces and moments that may, if
excessive, 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

The table in 4.7.2 summarizes the maximum forces
and moments allowed on M pump casings. Refer to
Flowserve for other configurations.

Ensure piping and fittings are flushed

before use.

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.

Page 19 of 42

Ensure piping for hazardous liquids is arranged

to allow pump flushing before removal of the pump.

4.7.2 Discharge piping

A non-return valve should be located in the discharge
pipework to protect the pump from excessive back
pressure and hence reverse rotation when the unit is
stopped.

Pipework reducers should have a maximum total
angle of divergence of 15 degrees. Fitting an
isolation valve will allow easier maintenance.

4.7.3 Auxiliary piping

The water lubricated bearings are fitted with lube
lines that end above the top plate. Pipe ends
terminate above the topplate and are normally left as
NPT male pipe nipples. The ends are capped.

4.7.4 Final checks

Check the tightness of all bolts in the discharge
pipework. Check also the tightness of all foundation
bolts.

4.8 Final shaft alignment check

After connecting piping to the pump, rotate the shaft
several times by hand to ensure there is no binding
and all parts are free.

Recheck the coupling alignment, as previously
described, to ensure no pipe strain. If pipe strain
exists, correct piping.

4.9 Electrical connections

4.9.1

Electrical connections must be
made by a qualified electrician in accordance with
relevant local, national and international regulations.

4.9.2

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.

4.9.3

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.

4.9.4

The motor must be wired up in
accordance with the motor manufacturer's
instructions (normally supplied within the terminal
box) including any temperature, earth leakage,
current and other protective devices as appropriate.
The identification nameplate should be checked to
ensure the power supply is appropriate.

4.9.5

A device to provide emergency stopping

must be fitted.

4.9.6 If not supplied pre-wired to the pump unit, the
controller/starter electrical details would also be
supplied within the controller/starter.

4.8.7 For electrical details on pump sets with
controllers see the separate wiring diagram.

4.8.8

See section 5.3, Direction of

rotation before connecting the motor to the electrical

supply.

4.10 Protection systems

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 be installed.

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

5.7.4 and 5.7.5.

5 COMMISSIONING, START-UP,
OPERA TION AND SHUTDOWN

Fully qualified personnel must

carry out these operations.

5.1 Pre-commissioning procedure

5.1.1 Lubrication

Determine the mode of lubrication of the pump set,
e.g. grease, product lubrication etc.

Grease lubricated pumps and electric motors are
supplied pre-greased. Other drivers and gearboxes, if
appropriate, should be lubricated in accordance with
their manuals.

In the case of product lubricated
bearings the source of product supply should be
checked against the order. The bearings below the
top plate are water lubricated. These will require
external clean supply. Commencement of lubrication
supply is required before pump start-up.

5.2.1.1 Recommended fill quantities

Refer to section 3.4.2, Pump and impeller data.

5.2.1.2

Lubrication schedule

When grease nipples are fitted, one charge between
grease changes is advisable for most operating
conditions, i.e. 1 000 hours interval.

Normal intervals between grease changes are 4 000
hours or at least every 6 months.
The characteristics of the installation and severity of
service will determine the frequency of lubrication.
Lubricant and bearing temperature analysis can be
useful in optimising lubricant change intervals.

The bearing temperature may be allowed to rise to
55 ºC (131 ºF) above ambient but should not exceed
95 °C (204 °F). For most operating conditions quality
grease having a lithium soap base and NLGI
consistency of No 2 or No 3 is recommended. The
drop point should exceed 175 ºC (350 ºF).

Never mix greases containing different

bases, thickeners or additives.

5.2.2 Water Lubricated Bearings

Bearings must be thoroughly wetted before
operation. In most cases the lower bearing will be
submerged but it is essential that a flush of clean
liquid be supplied.

5.2.2.1 Water Supply Pressure - 30-40 psig

5.3 Direction of rotation

Ensure the pump is given the same
rotation as the pump direction arrow cast on the
pump casing. Rotation is clockwise when the pump is
viewed from the driver. The impeller may unscrew if
run in reverse rotation.

On shut down, the impeller must be free to rotate. A
racket type motor must not be used.

Page 22 of 42

MJ SLURRY USER INSTRUCTIONS ENGLISH 71569294 - 02/08

®

Minimum submergence is recommended to avoid
vortexing and entrainment of air. Vortexing will result
in increased vibration, loss of performance and
reduced bearing lives.

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.

5.4 Guarding

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.

5.5 Priming and auxiliary supplies

Ensure all electrical, hydraulic,
pneumatic, sealant and lubrication systems (as
applicable) are connected and operational.

Ensure the inlet pipe and pump
casing are completely full of liquid before starting
continuous duty operation. Pump fluid must be above
the pump casing.

5.6 Starting the pump

a)

Ensure flushing and/or cooling
liquid supplies are turned ON before starting the
pump.

b) CLOSE the outlet valve.

c)

Ensure all vent connections are closed

before starting.

d) Start motor and check outlet pressure.
e) If the pressure is satisfactory, slowly OPEN outlet

control valve.

f)

Do not run the pump with the
outlet valve closed for a period longer than 60
seconds.

g) If NO pressure, or LOW pressure, STOP the

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

5.7 Running the pump

5.7.1 Venting the pump

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.

5.7.4 Bearings

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 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. Refer to section 6.2.3.1
for further information.

5.7.5 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.

Alarm and trip values for installed
pumps should be based on the actual measurements
(N) taken on the pump in the fully commissioned as
new condition. Measuring vibration at regular
intervals will then show any deterioration in pump or
system operating conditions.

5.7.6 Stop/start frequency

Pump sets are normally suitable for the number of
equally spaced stop/starts per hour shown in the
table below. Check actual capability of the driver and
control/starting system before commissioning.

5.8 Stopping and shutdo wn

a)

Close the outlet valve, but ensure
that the pump runs in this condition for no more
than a few seconds.

b) Stop the pump.
c) Switch off flushing and/or cooling/heating liquid

supplies at a time appropriate to the process.

d)

For prolonged shut-downs and
especially when ambient temperatures are likely
to drop below freezing point, the pump and any
cooling and flushing arrangements must be
drained or otherwise protected.

5.9 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.

5.9.1 Specific gravity (SG)

Pump capacity and total head in metres (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.

5.9.2 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.

5.9.3 Pump speed

Changing pump speed effects flow, total head, power
absorbed, NPSH

, noise and vibration. Flow varies

R

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

> NPSHR, and

A

that noise and vibration are within local requirements
and regulations.

5.9.4 Net positive suction head (NPSH

NPSH available (NPSH

) is a measure of the head

A

)

A

available in the pumped liquid, above its vapour
pressure, at the pump suction branch.

NPSH required (NPSH

) is a measure of the head

R

required in the pumped liquid, above its vapour
pressure, to prevent the pump from cavitating. It is
important that NPSH
between NPSH

A > NPSH

> NPSHR should be as large as

A

. The margin

R

possible.

If any change in NPSH

is proposed, ensure these

A

margins are not significantly eroded. Refer to the
pump performance curve to determine exact
requirements particularly if flow has changed. If in
doubt please consult your nearest Flowserve office
for advice and details of the minimum allowable
margin for your application.

5.9.5 Pumped flow

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

6 MAINTENANCE

6.1 General

It is the plant operator's responsibility to ensure
that all maintenance, authorized and qualified
personnel who have adequately familiarized
themselves with the subject matter by studying this
manual in detail carry out inspection and assembly
work. (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 5.8.

On completion of work all guards and safety devices
must be re-installed and made operative again.

Before restarting the machine, the relevant

instructions listed in section 5, Commissioning, start
up, operation and shut down must be observed.

Page 24 of 42

MJ SLURRY USER INSTRUCTIONS ENGLISH 71569294 - 02/08

®

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 guard rails 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 is used in the
maintenance process, the operator and anyone in the
vicinity must be careful and have the appropriate
protection.

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.

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".

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) Gland packings must be adjusted correctly to

give visible leakage and concentric alignment of
the gland follower to prevent excessive
temperature of the packing or follower.

c) Check for any leaks from gaskets and seals.

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

d) Check bearing lubricant level, and if the hours

run show a lubricant change is required.

e) Check that the duty condition is in the safe

operating range for the pump.

f) Check vibration, noise level and surface

temperature at the bearings to confirm
satisfactory operation.

g) Check dirt and dust is removed from areas

around close clearances, bearing housings and
motors.

h) 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.

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.

6.2.1 Routine inspection (daily/weekly)

The following checks should be made
and the appropriate action taken to remedy any
deviations:
a) Check operating behaviour. Ensure noise,

vibration and bearing temperatures are normal.

b) Check that there are no abnormal fluid or

lubricant leaks (static and dynamic seals) and
that any sealant systems (if fitted) are full and
operating normally.

c) Check that shaft seal leaks are within acceptable

limits.

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.

e) Check any auxiliary supplies e.g. heating/cooling

(if fitted) are functioning correctly.

 Refer to the manuals of any associated

equipment for routine checks needed.

6.2.2 Periodic inspection (six monthly)

a)

security of attachment and corrosion.

b) Check pump-running records for hourly usage to

determine if bearing lubricant requires changing.

c) The coupling should be checked for correct

alignment and worn driving elements.

Check foundation bolts for

 Refer to the manuals of any associated

equipment for periodic checks needed.

6.2 3 Re-lubrication

Lubricant and bearing temperature analysis can be
useful in optimizing lubricant change intervals. In
general however, the following is recommended.

See section 5.2.2 for grease

recommendations.

Regrease - via grease nipples every 1 000 hours or

sooner depending on the severity of the application.

It is important not to under or over grease the
bearings as this will lead to over heating and
premature failure.

a) Grease lubricated bearing housings have grease

nipples fitted in the bearing covers.

b) Move the axial seal ring back so the gap

between the pump shaft and bearing cover can

be seen.

c) Connect grease gun to the nipple.
d) Press grease into the bearing housing until the

first signs of it appear in the gap between the
housing and shaft, then stop greasing.

e) The maximum allowable operating temperatures

for anti friction bearings will vary from unit to unit,
depending on ambient and fluid temperature.
The rise above ambient should not normally
exceed 55 °C (131 °F) or a combined maximum
of 95 °C (204 °F).

f) A continuously rising temperature or an abrupt

temperature rise indicates a problem. If these
symptoms occur, stop the pump immediately and
investigate the cause.

TEMPERATURE

TIME

Grease change - every 4 000 hours or sooner

depending on the severity of the application.
a) Remove the bearing housing from the rotor

assembly.

b) Brush the bearing housing with hot kerosene

(100 to 115 °C/212 to 240 °F) or other non-toxic
solvent.

c) Clean and flush out the housing with a light

mineral oil.

d) Do not use waste oil to clean the housing.

To clean the bearings:

a) Wipe off as much grease as possible with a

clean lint-free cloth.

b) Brush bearings with hot kerosene (80 to 90 °C/

175 to 195 °F) while gently spinning the outer
bearing ring.

c) Spin each ball to ensure that it is clean.

To remove badly oxidized grease, which refuses to
come off:

a) Support the rotor in a vertical position and

immerse the bearing in hot kerosene or a mixture

of alcohol and light mineral solvent.
b) Gently spin the bearing outer ring.
c) Dry and reflush the bearing with clean light oil.
d) It is important not to under or over grease the

bearings as this will lead to over heating and

premature failure. It is recommended that the

bearings be filled with grease using a suitable

spatula. In addition the housings should be no

more than half filled.

6.3 Spare parts

6.3.1 Ordering of spares

Flowserve keep records of all pumps that have been
supplied. When ordering spares the following
information should be quoted:

1) Pump serial number

turn the casing upside down and lever the end of
the mounting studs. To prevent damaging the
studs nut can be threaded on and left loose.

6.9 Examination of 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.

6.9.1 Casing, seal housing and impeller

a) Inspect for excessive wear, pitting, corrosion,

erosion or damage and any sealing surface
irregularities.

b) Replace as necessary.

c) Inspect the impeller [2200] and the wearplates

seals. Check that the shaft is straight within 0.002
inch (0.050 mm).

6.9.3 Gaskets and O-rings

After dismantling, discard and replace.

6.9.4 Bearings

a) It is recommended that bearings are not re-used

after any removal from the shaft.

b) The plain liquid lubricated bearings may be re-

used if both the bearing bush and bearing sleeve
show no sign of wear, grooving or corrosion
attack. (It is recommended that both the bush
and sleeve be replaced at the same time.)

6.9.5 Bearing isolators, labyrinths or lip seals
(if fitted)

a) The lubricant, bearings and bearing housing

seals are to be inspected for contamination and
damage. If oil bath lubrication is utilised, these
provide useful information on operating
conditions within the bearing housing.

b) If bearing damage is not due to normal wear and

the lubricant contains adverse contaminants, the
cause should be corrected before the pump is
returned to service.

c) Bearing seals are not totally leak free devices.

Oil from these may cause staining adjacent to the
bearings. Inspect and replace if necessary.

6.10 Assembly

the sleeve using Loctite 680 and orientate the end of

Page 30 of 42

MJ SLURRY USER INSTRUCTIONS ENGLISH 71569294 - 02/08

®

the sleeve such that it protrudes about 19 mm (0.75)
below the bearing.

6.10.7 Multiple Intermediate Bearings

When there are multiple intermediate bearings there
will be 2 pc shafts. These will be coupled together
normally with a threaded type coupling. The direction
of drive will prevent coupling from coming loose.

6.10.7.1 2 pc Shafts

a) Inspect the end of the shafts and remove all dirt

and debris. Ensure that there are no burrs that
could prevent the shafts from seating against

each other squarely.
b) Thread the coupling onto the upper shaft.
c) Lift the lower shaft and align with the coupling

and screw into the coupling.

The end of the shafts must seat against
each other squarely to ensure that bearings and
impeller are properly aligned.

d) Install the intermediate bearing [3044] into the

bearing housing [3240], lock into place using
stainless steel setscrews.

e) Slide the housing onto shaft and position into the

support pipe spigot. The housing should align to
the top plate flush ports.

f) Slide the next section of support pipe over the

shaft and bolt into position. Secure bolts with
Loctite A. Tighten in accordance with table 2 for
steel bolts or table 3 for stainless steel bolts.

Repeat steps for addition intermediate bearings.

6.10.8 Lower Column Pipe
a) The orientation of the lower pipe must be such

that the access hole for the lower bearing [3000]
flush water is in alignment with the top plate.

b) Install the lower shaft sleeve onto the shaft. The

sleeve must be seated with Loctite A or 680.

c) Assemble the lower bearing [3000] into the lower

housing [3240] Align the flush port in the seal 90
degrees to the ports in the housing. Secure into
position using setscrews.

d) Slide the bearing housing [3240] over the shaft

and align the flushing port to the support pipe.

e) Install the sleeve stop [2460] on to the shaft

[2110] and seat to the shaft sleeve.

6.10.9 Lower Bearing Housing

a) Install studs in the gland side wear plate [1915.2]

and secure with loctite 242.

b) With gland side wear plates positioned with the

studs facing up; lift the lower seal housing [3200]
and lower onto the wear plate. Place the seal

washers [2905] over the studs followed by the
steel washers. Apply Loctite 242 or equivalent to
nut threads and fasten wear plate in position.
Torque nuts per table.

Assemble the lower bearing housing [3200] over the

shaft sleeve [2445] and orientate the flush port
with the mating hole in the column pipe to suit
auxiliary piping.

d) Seat the housing against the column pipe.

(Temporarily clamp the housing in place.)

6.10.10 Impeller Installation

a) Install the impeller spacer [2460] on standard

pumps only and install the impeller gasket
[4590.2] on all pumps.

b) Due to the method of assembling the impeller, it is

recommended to smear the sleeve face and both
sides of the impeller spacer [2460] with heavy
grease or a silicon sealant before assembling onto
the shaft, which will help to hold the impeller
spacer in position during assembly.

c) Apply anti-seize compound to the shaft threads

and screw the impeller onto the shaft. For large
sizes it is more practical to hold impeller using a
sling and hoist and turn the shaft.

Failure to tighten the impeller [2200]
spacer [2460] securely against the sleeve may
cause serious damage to pump components.

The thread is designed so that during
operation the impeller will tend to tighten onto shaft.
Therefore a clockwise shaft rotation (looking from
coupling end) will screw impeller on.

d) Release the thrust bearing housing hold down bolts

and tighten the jacking screws to pull the impeller
back to the stuffing box head [3200]. The stuffing
box head must not be rigidly clamped.

6.10.11 Suction Side W ea rplate

a) Install the studs [6572] in the wearplate [1915.1]

using Loctite grade A or equivalent.
b) Lift wearplate and install into casing.
c) Place the sealing washer [2905] over the studs

[6572]. Secure wearplate [1915.1] in place using

hex nuts and washers using Loctite 242 or

equivalent. Tighten in accordance with Table tables

in section 6.6.

Excessive or uneven tightening torque may distort
wearplate affecting impeller running clearances or result in
broken studs.

Page 31 of 42

MJ SLURRY USER INSTRUCTIONS ENGLISH 71569294 - 02/08

®

6.10.12 Casing

a) Smear a small amount of grease or anti-seize

compound over one face of the gasket [4590] and
place it on the stuffing box head [3200] with coated
face against flange.

b) Lift the casing and assemble to the pedestal. The

discharge may be orientated to various
configurations. Check the installation or GA drawing
for the proper position.

c) Secure into position. Ensure that the impeller is free

to rotate before tightening bolts.

d) Set the impeller front clearance in accordance with

instruction earlier in this section of the manual.

a) Assemble the mechanical seal gland plate and

gasket and fasten using gland studs [6572]. Secure
with nuts [6521] and tighten each by hand. Further
tighten the nuts in accordance with Table in 6.6.
Rotate the shaft to ensure that it turns freely without
rubbing or binding.

b) Re-assemble the rotating element into the casing.

Do not adjust the thrust bearing housing.

c) Set the deflector [2540] at the line bearing cover

[3260.1] so that they do not contact when the shaft
is rotated. Lock in place with the setscrews
provided.

6.11 Impeller axial clearance adjustment
NEVER ATTEMPT TO CHANGE THE

CLEARANCE WHEN THE PUMP IS RUNNING.

If the coupling has limited axial adjustment capability,
the pump and driver must be uncoupled prior to
adjusting the clearance in order to permit free
movement.
a) Loosen the two setscrews retaining the deflector

[2540] and check that the deflector is free to
move axially on the shaft.

b) Loosen the thrust bearing housing jam nuts and

back off the three jacking screws at least 1.5 mm
(0.060 inch).

c) Move rotor towards the wear plate [1915.1] by

tightening the three hold-down capscrews evenly
and uniformly until the impeller [2200] just
touches the wear plate. Rotating the shaft and
stopping the forward motion at the first sign of
rubbing can best establish this. If the shaft
cannot be rotated, back off the bearing housing
with the jacking screws until a just detectable rub
is obtained. Check that the gap between the two
machined faces of thrust bearing housing [3240]
and the bearing frame [3130] are parallel within

0.003 inch (0.076 mm). Adjust the jackscrews
and hold down capscrews as required to achieve
this parallelism. When impeller [2200] just
touches wear plate [1915.1] and thrust bearing
housing [3240] is parallel to the bearing frame
[3130] the axial clearance between the impeller
and wear plate is zero.

6.11.1 Option1

a) Place a dial indicator, set to end of shaft [1110]

or on housing [3240] face.
b) Set indicator reading to zero (0).
c) Note required impeller clearance.

6.11.2 Option 2

a) Measure and record the axial gap between the

thrust bearing housing flange and bearing frame

end face. Determine the required impeller axial

running clearance from Section I and add this to

the above measurement to establish the required

gap setting.

6.11.3

a) Loosen the thrust bearing housing hold down

capscrews slightly and tighten the jackscrews.

Until the required dial indicator reading (6.11.1)

or housing gap reading (6.11.2) is achieved.
b) Alternately and gradually tighten the hold down

capscrews and jackscrews until the required gap

setting is achieved at each hold down capscrew

location. Note that the gap at each jackscrew will

be slightly larger as a result of minor elastic

distortion of the thrust bearing housing flange

caused by the high pre-load forces. The gap

setting at any set of screws must be the same

within 0.003 inch [0.076 mm). Careful attention

to this procedure will help ensure long thrust

bearing life.
c) While preventing the jackscrews from rotating,

tighten the jam nuts to lock them in position.
d) Adjust the axial position of the deflector [2540] so

that it is clear of the line bearing cover [3260.1]

by approximately 0.030 inch (0.75 mm) and

tighten the setscrews firmly. Excessive

tightening may mar the shaft.
e) Manually rotate the shaft to ensure that there is

no rubbing or binding.
f) On belt driven units, adjust the pump or driver

sheave to maintain belt alignment. (Refer to

Page 32 of 42

Section 4.5.2.2).

g) Check the alignment on direct driven units (refer

to Section 4) and reassemble the coupling

h) Replace any safety guards, which may have

been removed.
