Pump dimensions and weights are shown on

the pump general arrangement drawing.

2.3 Storage

2.3.1 Temporary Storage for up to Six Weeks
If the pump is not to be used immediately, it

should be stored carefully in a horizontal
position, in a sheltered, dry location.
Additional rust preventative should be
applied to all unpainted carbon steel or cast
iron parts, and should not be removed until
final installation.

2.3.2 Long Term Storage

Shearing Hazard
Do NOT place fingers or hands etc.

into the suction or discharge pipe
outlets and do NOT touch the impeller, if
rotated this may cause severe injury.

To prevent ingress of any objects, retain the
protection covers or packaging in place until
removal is necessary for installation. If the
packaging or suction and discharge covers
are removed for inspection purposes,
replace afterwards to protect the pump and
maintain safety.

For special protection of electric motors,
refer to the manufacturers' instructions. In
the Appendix l.

2.3.3 Exposed or Extreme Conditions Storage

For exposed storage or extreme variants in

atmospheric or environmental conditions,
please refer to SPP Pumps Ltd. for special

applicable.

3. General Description

The SPP Pumps range of Eurostream

Pumps are horizontal centrifugal pumps that
comply with Pump Standard DIN24255.

The mechanical assembly comprises an

electric motor fitted with an extended shaft to
carry a double shrouded type impeller. This

Operators Instructions for

Eurostream Centrifugal Pumps

Manual No/Rev

W22-001E / 9

is connected by a support frame to an end
suction volute casing, fitted with wear ring(s).
The motor, frame, shaft and impeller
assembly can be withdrawn from the volute
for maintenance without disconnection of
pipework.

The discharge branch is normally positioned

vertically opposite the motor mounting feet,
but it can be orientated in any other direction
that the motor flange holes permit. Motors
can be supplied with or without slide rails,
and on smaller pump sizes only, flange
mounted motors may be specified.
Additional mounting feet are fitted to the
volute casing BUT these are NOT to be
used to support the pump unless the
pump is fitted with a flange-mounted motor.

The shaft is sealed with a standard

mechanical seal.

Nameplate details are shown on the back

cover, full pump specification can be
supplied on a data sheet, if requested.

Note (1) - Head specified is the Duty Head generated

by the pump only.

(2) - Suction pressure must be included when

assessing the Maximum Working Pressure.

For details of the motor supplied, refer to the

manufacturer's instructions in Appendix I.

4. Assembly and Installation

Shearing Hazard

Do NOT place fingers or hands

4.3 Pump Preparation

Abrasion and Entrapment

Hazard

Do NOT touch any moving or

rotating parts Guards are provided
to prevent access to these parts, where they
have been removed for maintenance they
MUST be replaced before operating the
equipment.

Remove packaging but leave the flange
covers in place, check that impeller rotates
freely by hand by turning the shaft.

4.4 Pump Installation

Eurostream pumps are designed to be
mounted on rigid foundations, using four
bolts to firmly attach the motor feet or slide
rails to suitable baseplate, framework or
concrete plinth. Only when using flange

mounted motors is the pump to be
mounted using the volute casing feet.

4.5 Suction Pipework

The run of suction pipework must be such
that air can NOT become trapped where it
would be sucked into the pump on starting.
The bore of suction pipe is recommended to
be one or two sizes larger than the pump
suction branch and reducers if used must be
eccentric to eliminate the possibility of an air
pocket being formed.

Unacceptable Suction Pipework

etc. into the suction or discharge
pipe outlets and do NOT touch the impeller,
if rotated this may cause severe injury. To
prevent ingress of any objects, retain the
protection covers or packaging in place until
removal is necessary for installation.

4.1 Initial Inspection for Damage

During transport and storage, accidental
damage to the pump may have occurred.
When the pump is to be installed, or in the
event of a handling accident, carefully check
that the pump has sustained no damage
before installation and commissioning.

4.2 Preparation for Mounting

Before installation, check that the pump
mounting location is suitable for accepting
the pump. Refer to Section 8, for details of
pump installation dimensions or to a certified
General Arrangement Drawing when
available.

Bends in the suction pipeline should be as
large as possible, the pipe made as short
and as straight as possible and all joints
must be fully airtight. If fitting a foot valve, it
should have a free area of one and a half
times the area of the suction pipe.

Where pumping water at temperatures
above 70°C, care must be taken to ensure
that enough pressure is available at the
impeller entry to prevent vaporisation.

An appropriate fine strainer is recommended
to prevent foreign matter from being drawn
into the pump. A screen or basket strainer
may also be required to hold back larger
items. These should be sized to maintain the

flow through them to below 0.6 m/s.

The suction pipe work must be flushed clean
to ensure that site debris is not drawn into
the pump when it is commissioned.

4.7 Discharge Pipework

The bore of the discharge pipe should be
sized to ensure a flow velocity of 2.5 to 3 m/s
is not exceeded. This is usually one size
larger than the discharge branch. Pipework
should be as short and straight as possible
to reduce friction head loss.

A non-return valve is usually fitted to prevent
the pump from excessive back pressure and
reverse rotation and a discharge valve is
usually fitted to regulate the flow and allow
for inspection and maintenance on the
pump.

The suction and discharge pipework must be
independently supported and positioned
such that no excessive forces and moments
are exerted on the pump flanges.

ATTENTION

Failure to support suction

and delivery pipework
may result in distortion of the pump casing,
with the possibility of early pump failure.

Preferred Pipework

4.8 Foundations

The motor feet or slide rails must be secured
to substantial foundations with suitable
foundation bolts to minimise vibrations. After
the pump has run for about 200 hours, the
foundation bolts should be checked for
tightness

Eurostream Centrifugal Pumps

5. Commissioning and Operation

5.1 Commissioning Checks
These checks must be done after first

installation and after pump maintenance that
required removal of the rotating assembly.

rotating parts Guards are provided to
prevent access to these parts, where they
have been removed for maintenance they
MUST be replaced before operating the
equipment.

Check that the rotating assembly is free to
rotate by hand before connecting the power
supply. Also check that the piping system
has been properly connected with all joints
tightened and instrumentation is in position.

ATTENTION

primed. Pumps should never be run dry as
the pumped liquid acts as a lubricant for the
close running fits surrounding the impeller
and damage will be incurred.

Prime the pump using an ejector, exhauster
or vacuum pump. If a foot valve is used in
the suction line the pump may be primed by
venting and filling the casing with liquid.

Connect the electrical supply to the pump
unit. Momentarily switch on motor and
check direction of rotation. This should be
such that the pump assembly turns
clockwise when viewed on the driven end.
For three phase electric motors, if direction
of rotation is incorrect, disconnect the
supply and change over two of three supply
wires.

Check that the suction valve is open and
that the pump is primed.

Open the discharge valve to one quarter
open to prevent hydraulic lock from
occurring. Switch on the motor and allow it
to build up to full operating speed. Slowly
open discharge valve until the pump
reaches the required duty condition.

Check that the motor is not overloading, unit
is not vibrating or excessively noisy, the
motor is not overheating, and that the pump
is developing the correct flow and head
requirements.
If the pump is operating at its normal speed,
the pump should be shut down at once if
any of the following defects are found:

a) No liquid delivered.
b) Not enough liquid delivered.
c) Not enough pressure.
d) Loss of liquid after starting.
e) Vibration.
f) Motor runs hot.
g) Excessive noise from cavitation.
h) Pump overheating.

Recommended corrective action for these
faults is given in Section 7 Faults and
Remedial Action.

5.3 During Operation

Hot Surfaces Hazard
Do NOT touch surfaces that during

normal running will be sufficiently hot
to cause injury. These are marked with the
HOT warning symbol. Note that these
surfaces will remain hot after the pump
has stopped; allow sufficient time for
cooling before maintenance. Be cautious
and note that other parts of the pump may
become hot if a fault is developing.

Cold Conditions Hazard

Do NOT operate water pumps in

temperatures below freezing point,

without first checking that the

pumped fluid is not frozen and the
pump is free to turn. Pumps in these
environments should be drained down
during inactivity and re-primed before
starting.

Hazardous Noise

In addition to local or site regulations

for noise protection, SPP Pumps Ltd.
recommend the use of Personal Ear
Protection equipment in all enclosed pump
rooms and particularly those containing
diesel engines. Care must be taken to
ensure that any audible alarm or warning
signal can still be heard with ear defenders

Our policy is one of continuous improvement and we reserve the right to alter specifications at any time

worn.

Periodic Checks:

a) Motor Bearings:
Check the bearing temperatures do not

exceed 70°C as an increase may indicate
the early stages of bearing trouble.

b) Noise:
Listen for any unusual noise or an increase

in normal sound level.

This may result from:

i) Loose fasteners for guards and other

equipment.

ii) Air trapped in the pump i.e. the pump was

not fully primed.

iii) Cavitation caused by air in the liquid from

leaks in the suction pipework.

iv) Small solids in the liquid.

NOTE - At certain installations or at certain

operation points on the pump curve, the
noise level 70dB (or the actual pump
specified noise level) can be exceeded.

c) Suction Gauge Reading:
If this is higher than normal, investigate and

check that valves in the suction pipework are
fully open or that the suction lift may have
increased.

d) Discharge Gauge Reading:
If this is lower than normal, check for a leak

in the associated pipework or that a valve in
the delivery line has been opened when
normally it is partially closed.

5.4 Stopping Procedure

Stop the motor then fully close the discharge

valve.

6. Maintenance and Service

The following hazards may arise during
maintenance work:

Fluid Pressure Jet Hazards

Check and ensure that the pump

operates at below the Maximum
Working Pressure specified in the manual or
on the pump nameplate and before
maintenance, ensure that the pump is
drained down.

Hazardous Materials

Wear a suitable mask or respirator
when working with packing or gasket
components that contain fibrous material, as
these can be hazardous when the fibrous
dust is inhaled. Be cautious, if other
supplier's components have been
substituted for genuine SPP Pumps parts,
these may then contain hazardous materials.

Hazardous Gases, Mists, Sprays
and Leaks

Be aware of the hazards relating to the
pumped fluid, especially the danger from
inhalation of noxious and toxic gases, skin
and eye contact or penetration. Obtain and
understand the hazardous substance
(COSHH) data sheets relating to the
pumped fluid and note the recommended
emergency and first aid procedures.

BEFORE ATTEMPTING ANY
MAINTENANCE ON A PUMP,
PARTICULARLY IF IT HAS BEEN
HANDLING ANY FORM OF HAZARDOUS
LIQUID, ENSURE THAT THE UNIT IS
SAFE TO WORK ON. THE PUMP MUST
BE FLUSHED THOROUGHLY WITH A
SUITABLE CLEANSER TO PURGE AWAY
ANY OF THE PRODUCT LEFT IN THE
PUMP COMPONENTS. THIS SHOULD BE
CARRIED OUT BY THE PLANT
OPERATOR AND A CERTIFICATE OF
CLEANLINESS OBTAINED BEFORE
STARTING WORK. TO AVOID ANY RISK

TO HEALTH IT IS ALSO ADVISABLE TO
WEAR PROTECTIVE CLOTHING AS
RECOMMENDED BY THE SITE SAFETY
OFFICER, ESPECIALLY WHEN
REMOVING OLD SEALS OR GASKETS
THAT MAY BE CONTAMINATED.

6.2 Preparation for Maintenance

Electric Shock & Accidental
Starting

Hazard

ISOLATE the equipment before any
maintenance work is done. Switch off the
mains supply, remove fuses, apply lockouts
where applicable and affix suitable isolation
warning signs to prevent inadvertent re­connection.

In order to avoid the possibility of
maintenance personnel inhaling dangerous
fumes or vapours. It is recommended that
maintenance work be carried out away from
the pump location by removal of the motor
and shaft assembly to a suitable
maintenance area.

No special tools are required for dismantling
and re-assembling, however, it is important
to ensure the suitable lifting equipment is
available and that the work is carried out in a
clean area.

6.3 Maintenance of Mechanical Seals

Generally there are is no maintenance
required on mechanical seals, they should
be replaced if leakage occurs.

6.4 Dismantling and re-assembly:

6.4.1 General

If the pump is maintained and serviced
regularly, breakdowns that require the pump
to be dismantled should not occur.

If a fault occurs, the cause should be
identified before dismantling. Refer to
Section 7 - Faults and Remedial Action.
Refer to Section 8 - for the Pump Section
Drawing for your pump.

When the pump is being dismantled, parts
must be handled with care, to avoid damage
by dropping and hammer blows.

Where new joints are made, correct gasket
thickness must be maintained.

After re-assembly the rotor must turn easily
by hand, otherwise premature pump failure
may occur.

6.4.2 Dismantling

Introduction

In general when pumps are dismantled,
inspected and/or replacement parts fitted,
the work is undertaken for one of the
following reasons.

a) Preventative Maintenance:

Because the time for the regular periodic

inspection has become due. Planned
inspection and maintenance at pre­determined intervals is a sound insurance
against a forced shutdown due to a failure at
a more inconvenient time.

b) Remedial Maintenance:

Perceptible fall off in pump performance
affecting capacity and pressure or: failure of
mechanical seal or: excessive and
continuous vibration with persistent noisy
operation.

The extent of dismantling required will
depend upon the reasons above.

In the case of preventative maintenance,
inspections are done at pre-selected times
and the pump usually requires complete
dismantling, so that all parts can be cleaned,
examined and measured for wear.

The extent of dismantling for remedial
maintenance will depend upon the cause of
failure and needs only to reveal the source of
the trouble.

When dismantling the pump, the volute
casing can remain mounted in the pipework.
Tightly shut both the inlet (if fitted) and outlet
valves and disconnect any external service
connectors.

On pumps using motors with frame sizes up
to and including D180M, it is NOT advisable
to remove the stub shaft under normal pump
maintenance conditions. On these pumps,
the stub shaft (21.11) is attached to the
motor using a collet nut and grub screw
arrangement. It requires special tools and
fixtures to remove and reassemble correctly.
It is recommended that this be performed
only by a trained SPP Pumps Ltd. Service
Engineer or an authorised SPP Pumps Ltd.
dealer/agent.

On pumps with larger motors, nominally over
22kW, the stub shaft locates positively onto
the motor shaft and is secured using a
Ringfeeder Shrink Disc assembly (150.0).

To dismantle pump, proceed in the following

sequence:

1. Drain liquid from the casing, remove plug
(90.3).

2. Unscrew nuts (92.09) on motor slide rail tee
bolts (90.8).

3. Unscrew nuts (92.0) on volute casing studs
(90.2

4. Motor (80.1), complete with supporting frame
(34.4) and casing cover (16.1), can now slide
back along slide rails (102.01) and clear of
volute casing (10.2).

Note! On the pumps fitted with a clamped casing

cover, care must be taken not to disturb the
joint between the casing cover (16.1) and
supporting frame (34.4).

5. The impeller (23.0) is now clear of casing
(10.2) and can be removed by unscrewing
the impeller nut (92.2) in a counter clockwise
direction and removing the lock washer
(93.0).

6. Remove the impeller key.

7. To remove the rotating elements of the
mechanical seal, either:

a) For the following pumps, fitted with shaft

sleeves (52.3).

32/13 32/16 32/20 32/26

50/13 50/16 50/20 50/26*
65/13 65/16 65/20*

80/16

With the impeller (23.0) and key (94.01)
removed, the shaft sleeve (52.3) complete
with the rotating element of the mechanical
seal (43.3) can now be slid off shaft (21.11).

Note * - Pump sizes 65/20 and 50/26 are
supplied in either configuration depending on
motor size.

b) or the following pumps, fitted with solid

stainless steel shafts (21.1) and abutment

125/26

With the impeller (23.0) and key (94.01)
removed the rotating element of the
mechanical seal (43.3) can be removed from
the shaft.

8. The seal should be carefully examined and if
worn, should be replaced. Do not remove
the rubber or elastomer bellows from the

sleeve, unless necessary for examination or
cleaning.

9. To remove the stationary element of the
mechanical seal:

a) For pumps fitted with bolted casing cover,

remove stud nuts (92.02) from casing cover
studs (90.22).

b) For pumps, fitted with a clamped casing

cover, and to continue dismantling pumps
fitted with bolted casing covers:

Remove the casing cover (16.1), complete
with the stationary element of mechanical
seal (43.3) from the supporting frame (34.4)
by carefully prising apart with screwdrivers or
similar tools which fit in recess between the
casing cover (16.1) and the supporting frame
(34.4).

Care must be taken to ensure that the
casing cover (16.1) does not damage the
shaft (21.1).

6.4.3 During and After Dismantling

6.4.4 Re-assembly

1. Ensure that all parts to be fitted are clean
and free from burrs, with screw threads and
abutting faces clear and free from damage

2. Lubricate the outer surface of the stationery
element of the mechanical seal (43.3) with
soapy water or silicone grease (not oil),
ensure that it is square to its housing in the
casing cover (16.1) and push home by hand,
taking care not to apply excessive force or to
damage the sealing surface. Check that it
has been seated fully and that the sealing
surface is clean and undamaged.

3. Refit the casing cover (16.1) to the support
frame (34.4). for bolted covers only, fit the
retaining nuts (92.02), tightening them
uniformly and in diagonally opposed pairs
sequence.

4. To fit the rotating element of the mechanical
seal (43.3), either:

a) For pumps fitted with stainless steel shaft

sleeve (52.3).

Lubricate the inner and outer surfaces of the

sleeve lightly with silicone grease. Locate
spring and spring holder of mechanical seal
over shaft sleeve (52.3).

Slide seal face assembly along sleeve (52.3)
