process.

This symbol indicates potential risks

connected with extremely high temperatures.

This symbol indicates potential risks

connected with extremely low temperatures.

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

START THE PUMP WITH
OUTLET VALVE FULLY OPEN
This is recommended to avoid the risk of overloading
and damaging the pump motor where greater power
is taken at low or shut off flow. Pump outlet valve
shall be adjusted to comply with the duty following the

Page 5 von 32

MSP USER INSTRUCTIONS ENGLISH 11/10

run-up process (See section 5 Commissioning,
startup, 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 back pressure on the pump may
overload the motor and cause cavitation. Low flow
rates may cause a reduction in
overheating of the pump, instability and
cavitation/vibration.

When ambient temperatures are
likely to drop below freezing point, the pump and any
cooling and flushing arrangements must be drai ned
or otherwise protected.

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 lbs) use a crane
corresponding to the mass and in accordance with
current local regulations.

NEVER DO MAINTENANCE WORK WHILST 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 sitting of the pump, limiting personnel
access and by operator training. If the liquid is
flammable and/or explosive strict safety procedures
must be applied.

Gland Packing must not be used when pumping
hazardous liquids.

condition these are extremely dangerous and skin
contact must be avoided.

GUARDS MUST NOT BE REMOVED WHILE

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 b e
avoided.

NEVER APPL Y HEAT TO REMOVE

IMPELLER
Trapped lubricant or vapour could cause an
explosion.

HOT AND COLD PAR TS

If hot or freezing components or auxiliary heating
supplies can present a danger to operators, they
must

be shielded to avoid accidental contact. If

complete protection is not possible, the machine
access must be limited to maintenance staff only.
Note: bearing housings must not be insulated and
drive motors and bearings may be hot.
If the temperature is greater than 68 °C (155 °F) or
below 5 °C (41°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

DRAIN PUMP AND ISOLATE PIPEWORK

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

FLUORO-ELASTOMERS (When fitted)

When a pump has experienced temperatures over
250 °C (482 ºF), partial decomposition of fluoro­elastomers (example: Viton) will occur . In this

Page 6 von 32

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

MSP USER INSTRUCTIONS ENGLISH 11/10

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 pump sets with a VFD, the ATEX Certification for
the motor must state that it covers the situation where
electrical supply is from the VFD. This is 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.

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.

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 temperatures it is recommended that
users fit an external surface temperature protection
device.

Avoid mechanical, hydraulic or electrical overload by
using motor overload trips or a Power Monitor and
make routine vibration monitoring.
In dirty or dusty environments, regular checks must
be made and dirt from areas around close
clearances, bearing housings and motors.

Maximum surface temperature (Tempe rature Class)
(see section 1.6.4.3)

1.6.4.3 Avoiding excessive surface temperatures

ENSURE THE EQUIPMENT TEMPERATURE

CLASS IS SUITABLE FOR THE HAZARD ZONE
Pumps have a temperature class as stated in the

ATEX Ex rating on the nameplate. These are based
on a maximum ambient of 40 °C (104 °F); refer to
Flowserve for higher ambient temperatures.

The surface temperature on the pump is influenced
by the temperature of the liquid handled. The
maximum permissible liquid temperature depends on
the temperature class and must not exceed the
values in the table that follows. The temperature rise
at the seals and bearings and due to the minimum
permitted flow rate is taken into account in the
temperatures stated.

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.

Page 7 von 32

1.6.4.5 Preventing sparks

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

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 non­metallic 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.

1.6.4.5 Preventing leakage

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

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

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

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

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

1.6.4.6 Maintenance to the centrifugal pump to
avoid the hazard

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

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

To avoid potential explosion hazards during
maintenance, the tools, cleaning and painting
materials used must not give rise to sparking or
adversely affect the ambient conditions. Where there

MSP USER INSTRUCTIONS ENGLISH 11/10

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).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.

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

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

The usual approach is to control the exposure
time to the noise or to enclose the machine to
reduce emitted sound. You may have already
specified a limiting noise level when the
equipment was ordered, however if no noise
requirements were defined, then attention is
drawn to the following table to give an indication
of equipment noise level so that you can take
the appropriate action in your plant.
Pump noise level is dependent on a number of
operational factors, flow rate, pipework design
and acoustic characteristics of the building, and
so the values given are subject to a 3 dBA
tolerance and cannot be guaranteed.
Similarly the motor noise assumed in the “pump
and motor” noise is that typically expected from
standard and high efficiency motors when on
load directly driving the pump. Note that a motor
driven by an inverter may show an increased
noise at some speeds.
If a pump unit only has been purchased for fitting
with your own driver then the “pump only” noise
levels in the table should be combined with the
level for the driver obtained from the supplier.
Consult Flowserve or a noise specialist if
assistance is required in combining the values.
It is recommended that where exposure
approaches the prescribed limit, then site noise
measurements should be made.
The values are in sound pressure level L
m (3.3 ft) from the machine, for “free field
conditions over a reflecting plane”.
For estimating sound power level L

then add 14 dBA to the sound pressure value.

2.0 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 and received in
writing within one month of receipt of the equipment.
Latter claims cannot be accepted.
Check any create/boxes/wrappings for any
accessories or spare parts, which may be packed
separately with the equipment or attached to side
walls of the box or equipment.
Each product has a unique serial number. Check that
this number corresponds with that advised and
always quote this number in correspondence as well
as when ordering spare parts or further accessories.

2.2 Handling

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

2.3 Lifting

Four lifting lugs are provided on the motor to lift the
complete unit.

Take care by applying slings or ropes about

auxiliary piping and seal systems.

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

2.4 Storage

If the unit will not be put immediately into service, it
should be stored in a dry room. To avoid any damage
during the storage period, the influence of any low or
high frequency vibration must be totally inhibited. If
the pump is delivered sealed in a plastic-wrapper, it is
of max. importance to avoid any damage of that
wrapper, because this will protect the pump against
humidity. Therefore it must be checked if this wrapper
has become cracked and if so, the wrapper must be
renewed.

2.4.1 Long period storage

If the pump is delivered in a plastic bag, the
preservations stands up for one year. If the storage
period exceeds this time, the preservation must be
checked and renewed. Also the air tight plastic bag
must be changed. Moreover we recommend to order
a Flowserve Service Engineer for checking the pump
before the first start up.

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 local regulations. If the
product contains substances, which are harmful to
the environment, these should be and disposed of in
accordance with current regulations. This also
includes the liquids and or gases in the "seal system"
or other utilities.

Make sure that hazardous substances are

disposed of safety and that the correct personal
protective equipment is used. The safety
specifications must be in accordance with the current
regulations at all times.

The VFD allows to operate the connected motor with
variable speed. Generally we supply the converter as
a completely wired unit including all contactors and
fuses. A RFI (radio frequency interference) - filter is
included to meet the requirements of the public
electricity supplier. All necessary safety features are
included, so that the unit needs only be connected to
the electrical power supply.

3.3.5 Coupling

The pump is rigid coupled to the motor. So the motor
bearings take all the load from the hydraulic forces.
The shaft of an electric motor must be a magnetic
material, so no stainless steels can be used. To
overcome this material restriction the impeller is
located on a separate shaft which is clamped to the
motor shaft via an annular spring clamping device.
Therefore also all kind of stainless steels and higher
Alloy can be used for pump shaft.

The coupling has the following design data:
Rated torque of motor = 95,5 Nm (70.4 ft-lbs)

Max. transm. torque of coupling = 1040 Nm (767 ft-lbs]
Max. transm. axial force = 59 kN (13275 lbs)

3.3 Design of major parts

3.3.1 Pump casing

Vertical inline design with flanged suction elbow and
integrated baseplate. It is directly flanged to the motor
stand, which itself is flanged to the motor. Back pull
out design for easy maintenance, so the casing
remains on its foundation in case of repair.

3.3.6 Control Circuit

The control circuit control, protect and adjust the main
circuit within the VFD cabinet.
Two filter-fan’s (12M1, 12M2) situated in the front
door obtain constantly the temperature
of the cabinet to avoid electronics damage and keep
pure from dirty air in the environment.
They start normally after switched-on the main switch
of the cabinet.
The PTC-thermistor’s tripping device (12K1) observe
the winding temperature of the main motor. When the
temperature exceeds the max. allowable value the
auxiliary contact (NC)

which is in line with the control circuit fuse (10F2) and
the auxiliary contact of the external motor fan (13Q1)
interrupt the safety loop requested by international
regulations. This cause an immediately stop of the
VFD itself.

MSP USER INSTRUCTIONS ENGLISH 11/10

For commissioning connect the PTC-thermistor’s
from the main terminal box of the main motor onto
terminals 1X1:27/28
For your convenience the implemented insulation
amplifier transform all incoming reference values into
a suitable current signal for the control board (11U1).
To adjust the insulation amplifier turn the screw into
the right position (see wiring diagram, page 12).
The motor-starter (13Q1) includes a thermal and
over-current protection to protect the external fan
cooling only. The motor has to be connected onto
terminals 1X1:29/30/31. It is necessary for
commissioning to switch on the starter otherwise the
VFD occur an external fault and it isn’t possible to
start the drive !
The transformer (10T1) is implemented to provide
230V~, 50Hz suitable for customer

3.4 Performance and operating limits

4.2 Part Assemblies

The pumps are delivered completely mounted and
prealigned with the motor. Also the shaft seal is in the
correct position. Final alignment after complete
installation is necessary. If drivers and/or seal systems
are delivered separately, follow the assembly
procedure in section 6.8.

4.3 Foundation

The foundation shall be located on a place that allows
a minimum of pipe work and that is easily accessible
for inspection during operation. According to the
environment the foundation may consist of concrete
or of steel. It must be rigid and heavy enough to
absorb normal vibrations and shocks.

4.3.1 Horizontal alignment of the baseplate

Horizontal alignment is done with levelling screws.
Use a spirit level for correct horizontal alignment of
the baseplate.

The max. misalignment is 0.5 mm/m

baseplate length.

4.3.2 Steel foundation

When the pump unit is mounted directly on structural
steel frame, it shall be well supported by constructural
beams. It is recommended to check the natural
frequency of the steel frame, because it shall not
coincide with the pump speed. The exact horizontal
alignment is very important!

In the interest of operator safety
the unit must not be operated above the nameplate
conditions. Such operation could result in unit failure
causing injury to operating personnel. Consult
instruction book for correct operation and
maintenance of the pump and its supporting
components.

4.0 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.

Refer to the general arrangement drawing for the
pump set.

4.3.3 Concrete foundation

A concrete foundation must have an exact horizontal
alignment and must be placed on solid ground. First a
basic foundation shall be built with square shaped
holes for embedding the foundation bolts. After
putting the base plate into the foundation the proper
alignment can be obtained by adjusting it with shims
under the base plate. Now insert the foundation bolts
and grout the space between the basic foundation
and the base plate with grouting cement (refer to
illustration)

It is very helpful to use a properly made and stable
wooden frame around the base plate. So the grouting
cement will not flow side. When the grouting is totally
set and hardened the foundation bolts shall be
tightened in a firm and symmetrical way.

Page 15 von 32

MSP USER INSTRUCTIONS ENGLISH 11/10

4.4 Piping

4.4.1 General

Protective covers are fitted to the pipe connections to
prevent foreign particles entering during
transportation and installation. Ensure that these
covers are removed from the pump before connecting
any pipes.
Maximum forces and moments allowed on the pump
flanges vary with the pump size and type. To
minimize these forces and moments which may
cause misalignment, hot bearings, worn couplings,
vibration and a possible failure of the pump, the
following points shall be strictly followed:

a) Prevent excessive external pipe load.
b) Do not connect piping by applying external force

(use of wrenches, crane,...). Piping shall be
aligned without residual stress.

c) Do not mount expansion joints so that their force,

due to internal pressure, acts on the pump flange.

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.
A non-return valve shall be located in the discharge
pipework to protect the pump from excessive back
pressure and hence reverse rotation when the unit is
stopped.
Piping and fittings shall be flushed before use. To
avoid damages of the pump install a Y-strainer or a
strainer of 40 mesh.
Piping for corrosive liquids shall be arranged to allow
pump flushing before removal of a unit.

4.4.2 Vent

All MSP pumps are provided with a vent connection
in the seal gland.

4.4.3 Drain

This connection is used for total drainage of the pump
casing. A flanged drain is standard and can be
optionally equipped with various kinds of valves.
Refer to GA drawing for details of the drain
connection.

By pumping toxic or explosive
media, provide the necessary security actions, e.g.
flushing with nitrogen.

4.5 Electrical connections

Electrical connections must 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 hazardous areas where compliance
with IEC60079-14 is an additional requirement for
making electrical connections.

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.

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.

The VFD must be wired up in accordance with the
VFD manufactures instruction book (normally
supplied within the front door of the electrical cabinet)

A device to provide emergency stopping must

be fitted.
For electrical details on pump sets with controllers

see the separate wiring diagram.

Page 16 von 32

The parameters of the VFD are

preset. Check it before initial start up.

4.6 Final shaft rotation check

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

5.0 COMMISSIONING START-UP,
OPERATION AND SHUTDOWN

These operations must be

carried out by fully qualified personnel.

5.1 Precommissioning procedure

a) The pump must be completely filled with liquid to

avoid running dry and to guarantee a correct
performance of the pump.

b) During filling the pump shall reach the specified

temperature, so pumps for hot liquids (T > 100 °C
(212 °F)) shall be warmed up by preflushing.

c) Check the sense of rotation of the pump.

Sense of rotation is clockwise viewed to the drive
end of the pump.

d) The pump rotor and the shaft seal must be in

correct axial position. Mounting plates of
mechanical seal must be locked at the seal gland
in open position. Drive-collar of the mechanical
seal sleeve must be tightened.

e) Check the readiness of all auxiliary systems (seal

sys., lubrication sys.,...) for start up.

f) All pipe work, including the internal and the

auxiliary pipe work, must be connected correctly
and must be absolutely tight. Check the tightness
of all connections of the auxiliary pipe work. The
suction valve must be open, the discharge valve
shall be closed.

g) Turn the pump by hand, if required with the help of

a lever, to check the free rotation of the rotor. The
rotor must turn uniformly and noiselessly. Some
resistance may be felt due to friction in bearings
and seals.

h) Check the readiness of the driver for start up. Refer

to the manual of the driver (preheating for
explosion proof E-motor).

5.3 Impeller clearance

No axial adjustment of the rotor is necessary.

5.4 Direction of rotation

The sense of rotation of the
pump is clockwise (CW); looking from the coupling to
the shaft end of the pump.

The rotation of the driver shall be checked at

minimum speed.

5.5 Guarding

Be sure that all guards are mounted correctly prior to
start up.

5.6 Priming and auxiliary supplies

The pump must be completely primed prior to start
up.
a) The pump casing must be vented via the vent

connection [V] in the seal gland.

b) Auxiliary systems, e.g. barrier /buffer fluid

systems, cooling circuits, shall be filled according
to the user instructions.

5.7 Starting the pump

a) Start the driver according to the specification.

(Refer to driver and VFD IOM).

Usually the initial start up is done by
"hand". Control via the VFD panel or remote
control. It is good practice to program a time ramp
for soft start. (Use 10s to speed up the unit
completely) After checking the sense of rotation
and several operation parameters like suction and
discharge pressure, speed, mechanical seal
operation, temperatures, the unit can be switched
to automatic mode (if a pump control system is
installed).

b) Check the discharge and suction pressure gauge

to verify the pumps delivered head. Open the
discharge valve slowly, until the pump reaches the
specified operation point. The pump must operate
smoothly, and the vibration must be below 5mm/s
(0.2 in./sec) (API 610 vibration limits).

If the backpressure of the discharge
pipe is sufficient, pumps can be started against
open valve.

Ensure that your driver is capable deliver

the higher torque required by starting against
open valve.

To prevent the pump from reverse rotation
after shut down, the installation of a check valve
is recommended.
Although the pump is not affected by reverse
rotation because of spezial couppling design , it
can be an issue with the driver.
Check the discharge and suction pressure gauge
to verify the pumps delivered head.
The pump must operate smoothly, and the
vibration must be below 5 mm/s (0.2 in./sec) (API
610 vibration limits).
If a minimum flow valve is installed, take pressure
gauge readings to verify the correct operation.

c) Check the pipe system against any leakage.
d) Check the mechanical seal against any leakage.

Right after start up a minor leakage
of the mechanical seal is quite normal. Normally
this leakage disappears after few minutes of
operation.

5.8 Operation

a) Verify that the pump is operating within the

specified limits, min/max flow, pressure,
temperature, vibration, power

b) The bearing housing temperature shall not exceed

105 °C (221 °F)and is observed by an integrated
PT100. If the bearing temperatures reaches 105 °C
(221 °F) the VFD control gives an alarm and shuts
down the unit.

Alarm or shut down are

selectable options and must be verified.

c) From time to time check the pump shaft seal.

Leakage of 10 - 20 drops per hour is also with a
mechanical shaft seal unavoidable.

d) Observe the power consumption of the pump to

detect excessive wear.

The discharge valve must be opened
within 30 sec. after start up. Longer operation
against closed discharge valve will damage the
pump. If a minimum flow valve is installed, take
pressure gauge readings to verify the correct
operation.

Page 19 von 32

5.9 Stopping and Shutdown

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. It is good practice to stop the

pump against a time ramp controlled by the VFD.
(Use 10s to stop the pump)

c) Switch off flushing and/or cooling/ heating liquid

supplies at a time appropriate to the process.

MSP USER INSTRUCTIONS ENGLISH 11/10

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.

For automatic start/stop operation of the

pump, ensure that all steps described in chapter 5.6,

5.7, 5.8 and 5.9 are implemented in the control logic.

5.10 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 will
help the user to decide how to evaluate the
implications of any change. If in doubt contact your
nearest Flowserve office.

5.10.1 Specific gravity (SG)

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

5.10.2 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.

5.10.3 Pump speed

Changing pump speed effects flow, total head, power
absorbed, NPSHR, noise and vibration. Flow varies
in direct proportion to pump speed. Head varies as
speed ratio squared. Power varies as speed ratio
cubed. If increasing speed it is important therefore to
ensure the maximum pump working pressure is not
exceeded, the driver is not overloaded,
NPSHA>NPSHR, and that noise and vibration are
within local requirements and regulations.

5.10.4 Net positive suction head (NPSH

NPSH available (NPSHA.) is a measure of the
energy available in the pumped liquid, above its
vapour pressure, at the pump suction branch.
NPSH required (NPSHR.) - is a measure of the
energy required in the pumped liquid, above its
vapour pressure, to prevent the pump from cavitating.

A)

It is important that NPSHA >NPSHR. The margin
between NPSHA >NPSHR should be as large as
possible. If any change in NPSHA is proposed,
ensure these 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
for advise and details of the minimum allowable
margin for your application.

5.10.5 Pumped flow

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

only if required (see chapter 6.8) to keep axial
clearance of impeller.

6.8 Examination of parts

1) Pumps with semi open impeller have no wear
rings. Check the wear plate and the impeller
[2200] against any wear. Semi open and free flow
impellers have back vanes, which shall be
checked against any wear.

2) Check all parts against corrosion and erosion.

3) Carefully check the coupling against any wear.

4) Rotate the angular contact bearing by hand, to
check against abnormal sound. Check the
bearing cages against any wear and the outer
and inner race against running marks. Check the
runout of the shafts. TIR (Total Indicated Runout)
shall not exceed 0.04 mm/m (0.0005 in./ft) of
length. TIR shall not exceed 0.08 mm (0.003 in.)
over total shaft length.

6.9 Assembly

To assemble the pump consult the sectional
drawings.

Ensure threads, gasket and O-ring mating faces are
clean. Apply thread sealant to non-face sealing pipe
thread fittings.

Drain the seal system, if

applicable.

4) Loose the hex nuts [6581.2] to disconnect the
pump casing [1110] from the motor hydraulic
assembly. Use hexagon head bolt [6577] to
support this.

5) Pull out the motor hydraulic assembly and bring it
to a workshop.

6) Unsecure lockwasher [6541] and loose impeller
nut [2912] (right hand thread)

If the pump is equipped with an

inducer [2215] loose inducer.

7) Pull off the impeller [2200] by using two studs
screwed into the threads at the impeller shroud.
Remove also key [6700].

8) Loose socket head cap screws [6579.2] and pull
off the diffuser insert [1649].

Replace O-rings [4610.2],

[4610.1] after each disassembly.

9) Loose socket head cap screws [6579.3] and pull
off the casing cover [1221] together with the
mechanical seal.

10) Loose hex nuts [6581.3] and pull out the
mechanical seal.

11) Open the clamping ring [2542] and pull off the
pump shaft [2100] with help of the jack screws.

6.9.1 Assembly of pump

If the pump shaft [2100] has not been pulled off, use
reverse disassembly procedure.

6.9.2 Assembly of the hydraulic cartridge

This procedure shall be used, if the pump shaft
[2100] has been pulled off.

1) Mount the mechanical seal into the casing cover
[1221]. Tight hex nuts [6581.3] of studs [6572.3].

2) Insert carefully the pump shaft [2100] into the
shaft seal assembly and install tool [9310] into
the foreseen shaft nut. Move the hydraulic
assembly upwards until the tool [9310] touches
the pump casing cover [1221]. Now the shaft
needs to be fixed in this position by locking the
clamping ring [2542].

3) Put the clamping ring [2542] to the pump shaft
[2100] and slide the hydraulic cartridge consisting
of mechanical seal, pump shaft [2100] and casing
cover [1221] to the motor shaft.

4) Insert the O-ring [4610.2] and fix the hydraulic
cartridge with the socket head cap screws to the
bearing lantern [3140].
Now the pump shaft [2100] has reached its
correct axial position.

5) Tight the clamping unit crosswise with the
required torque of 7 Nm (5.2 lbf.ft)

Page 24 von 32

MSP USER INSTRUCTIONS ENGLISH 11/10

The clamping surfaces must

be absolutely grease free.

6) Open the socket head cap screws and remove
the tool [9310].

Store the tools outside the pump for

latter use.

7) Insert the O-rings [4610.1] and slip on the diffuser

insert [1649] to the casing cover [1221]. Tight the
socket head cap screws [6579.2].

8) Put in the key [6700] and slip on the impeller

[2200] and the lockwasher [6541]. Tight the
assembly with the impeller nut [2912] and secure
it with the lockwasher [6541].

If the pump is equipped with an

inducer [2215] replaces the shaft nut.

9) Now the complete motor hydraulic assembly can

be put into the casing. Tight hex nuts [6581.2] of
the studs [6572.2].

Take care of the ring [2500]
to ensure correct position of the motor hydraulic
assembly in the casing.

7.0 AUXILIARIES

7.1 Seal and seal system

7.1.1 Single Mechanical Seal with API – Plan 01

Refer to mechanical seal drawing and
auxiliary piping drawing.
The pump is equipped with a single mechanical seal.
The cartridge design allows to change the
mechanical seal without taking it apart.

Try to turn the rotor by hand.If the
rotor cannot be turned, the pump must be
disassembled, refer to section 6.7.1 Dismantling

MSP.

Actions after start up:
Check all connections to the seal gland and the
mechanical seal itself against leakage. It is usual that
at the seal faces a small leakage occurs after start
up, which decreases with the time of operation and
should stop after the seal is run in. Check the
temperature of the seal gland. I slight increase of
temperature may be observed during the run in
period. Flushing of primary mechanical seal is
performed according to API 610 flushing plan 01.
Plan 01 is similar to a Plan 11 except that internal
porting is used to direct flow to the seal chamber from
an area behind the impeller near the discharge.

The product is led internally through a bore of a small
diameter (reduction of quantity) from the seal
chamber to flush the primary seal.

Disassembly of the seal cartridge
is only allowed by authorized personal. Contact
Flowserve for any service of the mechanical seal. We
recommend to have a spare cartridge seal on stock
for easy replacement.

7.1.2 Single Mechanical Seal with API – Plan 23

Refer to mechanical seal drawing and
auxiliary piping drawing.
The pump is equipped with a single mechanical seal.
The cartridge design allows to change the
mechanical seal without taking it apart.

Try to turn the rotor by hand.If the
rotor cannot be turned, the pump must be
disassembled, refer to section 6.7.1 Dismantling

MSP.

Actions after start up:
Check all connections to the seal gland and the
mechanical seal itself against leakage. It is usual that
at the seal faces a small leakage occurs after start
up, which decreases with the time of operation and
should stop after the seal is run in. Check the
temperature of the seal gland. I slight increase of
temperature may be observed during the run in
period. The mechanical seal is flushed by an API
Plan 23 and the temperature at the seal gland should
be below the pumped liquid temperature (refer to
mechanical seal drawing for temperature limit).

Plan 23 is the plan of choice for all hot water
services, and it is also desirable in many hydrocarbon
and chemical services where it is necessary to cool
the fluid establish the required margin between fluid
vapour pressure (at the seal chamber temperature)
and seal chamber pressure. In a Plan 23, the cooler
only removes seal face-generated heat plus heat
soak from the process.

For cooling flow and pressure
refer to GA-drawing.

Disassembly of the seal cartridge
is only allowed by authorized personal. Contact
Flowserve for any service of the mechanical seal. We
recommend to have a spare cartridge seal on stock
for easy replacement.

Page 25 von 32

7.2 Changing of mechanical seal

1) Completely drain the pump by using the drain
connection. By pumping explosive or toxic media,
flush the system with Nitrogen.

2) Secure the mechanical seal by putting the
mounting plates into the groove of the shaft
sleeve. Loose the clamping device, and
disconnect the seal piping.

Drain the seal system, if

applicable.

3) For disassembly refer to section 6.7.1,
Dismantling of pump.

4) For assembly refer to section 6.9.1, Assembly of

pump
