Warning
Always lift the pump by the marked lifting points

or by means of a fork-lift truck.
To make the use of a fork-lift truck when moving

a pump safer, the approximate centre of gravity is
marked with a label attached to the
transportation stand. Make sure the centre of
gravity is between the fork-lift arms when lifting
the pump.

Never lift the pump by the power supply cables.
It may result in electric short-circuit and risk of
electric shock when the pump is connected to the
mains. The cables and cable entry may be
damaged, leading to loss of watertightness and
consequent severe damage to the motor.

TM03 4459 0208TM04 6068 4809

Warning
If during transportation, assembly or dismantling

the pump is tilted more than 10 ° in any direction
from its normal position (EN 809, 5.2.1.4), the
pump may lose its stability. Secure the pump by
means of chains or place it in horizontal position.

Warning
Make sure that the lifting brackets are tightened

before attempting to lift the pump. Tighten if
necessary. Carelessness during lifting or
transportation may cause injury to personnel or
damage to the pump.

5.3 Storage

For long periods of storage the pump must be protected against
moisture and heat.

Storage temperature: -20-55 °C. Maximum 70 °C for short
periods not exceeding 24 hours (EN 60204-1, 4.5).

After a long period of storage, inspect the pump before putting it
into operation. Make sure that the impeller can rotate freely.
Pay special attention to the condition of the shaft seals, O-rings
and the cable entry.

6. Installation

The extra nameplate supplied with the pump should be fixed at
the installation site.

All safety regulations must be observed at the installation site, for
instance the use of blowers for fresh-air supply to the pit.

Prior to installation, check the oil level in the oil chamber, see
section 10.1 Oil check and oil change.

6.1 Installation types

S pumps, ranges 72, 74 and 78 are designed for various
installation types.

Figures 13 to 20 show the possible installation types.

Installation types C and S

Submerged installation on auto-coupling.

Fig. 13 Permanent installation in pit

The pump can easily be pulled out and lowered into the pit by
means of the guide rails. The stop level is lower for type C than
for type S. See fig. 13.

Fig. 14 Upper guide rail bracket

Fig. 15 Intermediate guide rail bracket; required if guide rails

are more than 6 m long

Correct pedestal height for installation on auto-coupling is
important in order to obtain the best efficiency for the pump.

Fig. 16 Auto-coupling base installation on pedestal

Caution

Do not remove the protection hose from the free
end of the supply or sensor cables until the
electrical connection is to be made.
Whether insulated or not, the free cable end must
never be exposed to moisture or water.
Non-compliance with this may cause damage to
the motor.

Caution

If the pump is being stored for more than two
months, the impeller must be turned by hand at
least every two months to prevent the lower
mechanical seal faces from seizing up. If not, the
shaft seal may be damaged when the pump is
started. If the impeller cannot be turned by hand,
contact an authorized service workshop.

Caution

Make sure the cooling jacket is empty before
storing the pump.

Warning
During installation always support the pump by

means of lifting chains or place it in horizontal
position to secure stability.

Warning
Before beginning the installation, switch off the

power supply and lock the main power switch in
position 0.

Any external voltage connected to the pump
must be switched off before working on the
pump.

Warning
Do not put your hands or any tool into the pump

suction or discharge port after the pump has
been connected to the power supply, unless the
main power switch has been locked in the 0­position.
Make sure that the power supply cannot be
accidentally switched on.

Warning
We recommend that you always use Grundfos

accessories to avoid malfunctions due to
incorrect installation.

6.2 Start and stop levels

The start and stop levels are specified during the design stage.
Always check that the start/stop levels function and possibly alter
them when commissioning the pump in order to ensure good
operation.

The stop level should be as low as possible, so that the flow
velocity in the pit increases towards the end of the working cycle.
In pumping stations with several different stop levels, such as in
frequency-controlled installations, it is important to program the
control sequence to pump down to the lowest stop level at least
once per day to clean out the bottom. Limits for the stop level are
set by the motor submergence required to ensure cooling, by the
onset of pump cavitation or by the level where air is sucked into
the pump inlet. The lowest level cannot always be foreseen, but
must be confirmed through trials during pumping station
commissioning.

Further details regarding stop and start levels for submerged or
dry installation appear under sections 6.3 Submerged installation

on auto-coupling and 6.5 Dry installation.

6.3 Submerged installation on auto-coupling

Pumps for permanent installation can be installed on a stationary
auto-coupling and operated completely or partially submerged in
the pumped liquid.

Before installing the auto-coupling base unit ensure the quality
and strength of the concrete foundation. Table A below shows the
pull-out strength required for expansion bolts of the auto­coupling. To ensure adequate pull-out strength we recommend
that you weld the threaded bushings to the steel reinforcement in
the concrete.

1. Drill mounting holes for the guide rail bracket on the inside of
the pit and fasten the guide rail bracket provisionally with two
screws.

2. Place the auto-coupling base unit on the bottom of the pit.
Use a plumb line to establish the correct positioning.
Fasten the auto-coupling with expansion bolts. If the bottom of
the pit is uneven, the auto-coupling base unit must be
supported so that it is level when being fastened.

3. Assemble the discharge pipe in accordance with the generally
accepted procedures and without exposing the pipe to
distortion or tension. No loads from the pipework weight must
be carried by the auto-coupling.

4. Fit the guide rails. An intermediate guide rail bracket is
required if guide rails are more than 6 m long. Place the guide
rails on the auto coupling, then place the guide rail bracket on
the guide rails and fasten the guide rail bracket to the wall.
Tighten the expansion bolts.

5. Clean out debris from the pit before lowering the pump into
the pit.

6. Before lowering the pump into the wet pit, check the cables
visually for cuts or ruptures which may have been caused by
rough handling during transportation or installation.

7. Slide the guide claw of the pump between the guide rails and
lower the pump into the pit by means of a certified chain
secured to the lifting bracket of the pump. When the pump
reaches the auto-coupling base unit, the pump will
automatically connect tightly.

8. Hang up the end of the chain on a suitable hook at the top of
the pit and in such a way that the chain cannot come into
contact with the pump.

9. Adjust the length of the motor cables but remember to have
enough cable length to be able to make service on the pump.
Make sure that the cables are not sharply bent or pinched.
Fix the cables at the top of the pit in such a way that no extra
cable slides into the pit.

10. Connect the motor cables and the sensor cable.

Table A

Please note that the strengths given are without safety factor.
Required safety factor may depend on the materials and the
method used for anchoring.

6.4 Column pipe installation

Pumps for column pipe installation are installed permanently in a
column pipe. Grundfos does not normally supply the column pipe.
Dimensioning of the column pipes is suggested in the pump
specific dimensional drawings.

1. Fit the seat ring to the bottom of the column pipe.

2. Clean out debris from the pit.

3. Before lowering the pump into the column pipe, check the
cables visually for cuts or ruptures which may have been
caused by rough handling during transportation or installation.

4. Lower the pump into the column pipe by means of a certified
chain secured to the lifting bracket of the pump. The pump will
sit against the conical surface of the seat ring. Normally the
friction between the conical surfaces will prevent the pump
from rotating. As an extra precaution there are three guide
pins on the seat ring which will limit the possible rotation to
maximum 60 °.

5. Hang up the end of the chain above or at the top of the
column pipe in such a way that the chain cannot come into
contact with the pump.

6. Adjust the length of the cables but remember to have enough
cable length to be able to service the pump. Make sure that
the cables are not sharply bent or pinched. Fix the cables in
such a way that there is no extra slack in the column pipe.
With long columns it may be necessary to arrange cable
support for the cable inside the column pipe. If necessary,
please contact Grundfos.

7. Connect the motor cables and the sensor cable.

Fig. 21 Column pipe installation pump type ST

Note

For auto-coupling installations (types S and C),
the guide claw is mounted on the discharge
flange from factory.

Caution

Avoid pipe tension at flanges and bolts.

Caution

The free end of the cables must not be
submerged, as water may penetrate through the
cables into the motor.

6.5 Dry installation

Pumps in dry installation are installed permanently in a pump
room.

The pump motor is enclosed and watertight and will not be
damaged if the installation site is flooded with water.

1. Mark and drill mounting holes in the concrete foundation.

2. Fit the base stand on the concrete with expansion bolts.

3. Check that the base stand is horizontal.

4. Fasten the pump to the base stand.
In order to facilitate service on the pump, we recommend that you

fit isolating valves on either side of the pump.

5. Fit the suction and discharge pipes and isolating valves, if
used, and ensure that the pump is not stressed by the
pipework.

6. Adjust the length of the motor cables but remember to have
enough cable length to be able to service the pump.
Make sure that the cables are not sharply bent or pinched.

7. Connect the motor cables and the sensor cables according
the wiring diagrams.

The suction and discharge pipes are bolted to the pump by
means of flange connections.

Stop levels

The stop level setting for dry-installed pumps depends on the
suction pipe inlet height, shape and flow velocity. Set the stop
level approx. one inlet pipe diameter above the suction pipe inlet.
The final stop level should be confirmed through test runs during
pumping station commission.

Start levels

In pumping stations with dry-installed pumps, set the starting
levels above the pump housing in order to ensure that the cooling
jacket is filled up before the pump starts pumping. For vertical
pumps, this height may be considerable and should be set with a
margin according to fig. 22.

Fig. 22 Vertical, dry installation (D)

Horizontal pumps do not normally require special considerations
for the start levels, if the suction pipe is designed to prevent air
pockets from forming, see fig. 23.

Fig. 23 Horizontal, dry installation (H)

Legend to figures 23 and 24:

S is the minimum stop level. The minimum distance S above the

suction pipe is required to avoid the formation of vortices at the
suction pipe and thus to avoid air getting sucked into the pump.
Air in the pumped liquid may cause vibrations, cavitation and loss
of pump performance.

G is the minimum start level of a dry-installed, vertical pump if no
other actions are taken to ensure that the pump housing is filled
with pumped liquid when the pump is started. Other actions could
be to use a vacuum pump to suck liquid into the pump housing
(requires isolating valve on the pressure side) or (after the first
startup) a non-return valve in the discharge pipe which prevents
the draining of the pump housing between running periods.

Note

For vertical, dry installations, type D, the pump
needs to be installed on a permanent concrete
foundation.

Note

For horizontal, dry installations, type H, the pump
is mounted on a base stand from factory.

Note

We recommend that you use a reducer between
the suction pipe and the pump in dry
installations. In horizontal installations the
reducer must be of the eccentric type and must
be installed so that the straight edge is pointing
upwards. In this way, the accumulation of air in
the suction pipe is avoided and the risk of
disturbance of operation is eliminated.
See fig. 23.

Note

Make sure that the pipework is installed without
the use of undue force. No loads from the
pipework weight must be carried by the pump.
We recommend that you use loose flanges to
ease the installation and to avoid pipe tension at
flanges and bolts.

Note

Do not use elastic elements or bellows in the
pipework; these elements should never be used
as a means to align the pipework.

7. Motor protection

Motor protection devices

The motors have three thermal protectors connected in series
and two moisture switches connected in series. Protectors and
switches are connected in two separate circuits. The thermal
protectors are of the reversible type, and the moisture switches
are of the irreversible type. The thermal protection circuit
(conductors 1 and 3) and the moisture protection circuit
(conductors 2 and 3) have separate outputs to enable separate
alarms if motor is overheated or affected by moisture.

All other sensor connections are either led out of the motor
(sensor version D) via conductors 4 to 9, see fig. 26, or
connected to the sensor board (sensor version B) and led out of
the motor via conductors 4 and 5.

7.1 IO 113

IO 113 forms interface between a Grundfos sewage and
wastewater pump with analog and digital sensors and the pump
controller. The most important sensor data are indicated on the
front panel.

One pump can be connected to an IO 113 module.
Together with the sensors, IO 113 forms a galvanic separation

between the motor voltage in the pump and the controller
connected.

IO 113 can do the following as standard:

• Protect the pump against overheating.

• Monitor the status of these items:

- motor winding temperature

- leakage (WIO)

- moisture in pump.

• Measure the stator insulations resistance.

See section 7.1.2 Measurement of insulation resistance.

• Stop the pump in case of alarm.

• Remotely monitor the pump via RS-485 communication

(Modbus or GENIbus).

• Control pump via a frequency converter.

When IO 113 is combined with SM 113, it is also possible to
monitor the bearing temperature and rotor speed when the motor
is switched off.

7.1.1 Galvanic separation

Double-insulated sensors for all measurements ensure the
electrical safety. Furthermore, there is a galvanic separation
inside IO 113.

7.1.2 Measurement of insulation resistance

IO 113 measures the insulation resistance between a stator
winding and earth:

• Resistance above 10 MΩ = ok.

• Resistance between 10 MΩ and 1 MΩ = warning.

• Resistance below 1 MΩ = alarm.

7.2 SM 113

SM 113 is designed and used for the collection and transfer of
additional sensor data. SM 113 works together with IO 113 (with
communication module, product number 98097390) as shown in
the figure below.

Fig. 24 IO 113 and SM 113

SM 113 can collect data from these devices:

• Current sensors, 4-20 mA*

• Pt100**/ Pt1000*** thermal sensors.
* Vibration sensor, water-in-oil or water-in-air sensor

(WIO or WIA)
** Maximum three Pt100 sensors
*** Maximum four Pt1000 sensors

7.3 Switches and sensors

A pump includes the following switches and sensors:

• three thermal switches in the stator windings

• thermal protectors

• a moisture switch in the top cover

• a moisture switch in the stator housing

• a Pt100 in the stator winding (analog)

• a Pt100 in the upper bearing (analog)

• a Pt100 in the lower bearing (analog)

• a WIO (water-in-oil) sensor in the oil chamber (analog).

7.3.1 Thermal switches

The thermal protection against overheating is achieved with
bimetallic switches as standard or thermistors as optional.
The three thermal switches that are hardwired from the pump to
the IO 113 unit (or similar controller) will open if the stator
windings become too hot. The thermal switches are of the
reversible type and will close again when the motor has cooled
down.

This generates both a hardware and software alarm in the IO 113,
and the alarm relay will open.

7.3.2 Pt100

S pumps, ranges 72, 74 and 78 are equipped with Pt100 sensors
in the stator windings, in the upper bearing bracket and in the
lower bearing bracket.

Pt100 makes an analog measurement from 0-180 °C.
The value is measured by the SM 113 and transferred to the
IO 113 through serial communication.

7.3.3 WIO (water-in-oil) sensor

The oil chamber is filled with oil acting as lubricant and coolant for
both mechanical seals.

The WIO sensor measures the water content in the oil chamber:

• 0-20 % water in the oil = no reaction

• water content outside measuring range = warning

• oil level too low = alarm.

Technical data

The sensor is approved as CE 0344 II 2 GD Ex mb II T4,II 2 D
Ex mD 21 T135 °C IP68 according to EN 60079-0:2006,
EN 60079-18:2004, EN 61241-0:2006 and EN 61241-18:2004.

7.3.4 Moisture switch

The pump has two moisture switches, one in the top cover and
one in the stator housing. The moisture switches are of the
irreversible type and must be replaced if activated.

The moisture switches are hardwired from the pump to the IO 113
(or similar controller). They will open if moisture is detected and
thus break an electric circuit.

This will generate both a hardware and software alarm in the
IO 113, and the alarm relay will open.

TM04 6067 4809

Warning
The installer/user must install an automatic

circuit breaker, e.g. IO 113, which disconnects the
power supply in case the thermal switches or the
moisture switches are not operating.

IO 113 must not be installed in potentially
explosive environments.

8. Electrical connection

The supply voltage and frequency are marked on the pump
nameplate. Make sure that the motor is suitable for the power
supply available at the installation site.

The pump must be connected to a motor-protective circuit
breaker.

In the case the pump does not have an SM 113, the Pt100
sensors must be hard-wired out of the pump, see fig. 26, and
connected to an external unit.

In the case the pump has an SM 113, the Pt100 sensors must be
connected to the SM 113. No external unit is required.

The motor is effectively earthed via the earth conductors of the
power cables and the pipework. The motor top cover for Ex
pumps is equipped with connections for external earthing or an
equipotential bonding conductor.

The most commonly used startup methods are direct-on-line
starting (DOL), star-delta starting (Y/D) and soft start. The pump
can even be started via a frequency converter according to the
frequency converter manufacturer's specifications. The selection
of suitable starting method depends on several considerations on
usage and mains supply conditions.

Fig. 28 Star-delta starting

8.1 Cross-sections for power cables

There are three different types of power cable in use:

• one standard four-core power cable

• two different types of EMC power cable.
All cable types are shown in this booklet.

8.3 Frequency converter operation

In principle, all three-phase motors can be connected to a
frequency converter.

However, frequency converter operation will often expose the
motor insulation system to a heavier load and cause the motor to
be more noisy than usual due to eddy currents caused by voltage
peaks.

In addition, large motors driven via a frequency converter will be
loaded by bearing currents.

For frequency converter operation, please observe the following
information:

• Requirements must be fulfilled.

• Recommendations ought to be fulfilled.

• Consequences should be considered.

8.3.1 Requirements

• The thermal protection of the motor must be connected.

• Peak voltage and dU/dt must be in accordance with the table
below. The values stated are maximum values supplied to the
motor terminals. The cable influence has not been taken into
account. See the frequency converter data sheet regarding the
actual values and the cable influence on the peak voltage and
dU/dt.

• If the pump is an Ex-approved pump, check if the Ex certificate
of the specific pump allows the use of a frequency converter.

• Set the frequency converter U/f ratio according to the motor
data.

• Local regulations/standards must be fulfilled.

8.3.2 Recommendations

Before installing a frequency converter, calculate the lowest
allowable frequency in the installation in order to avoid zero flow.

• Do not reduce the motor speed to less than 60 % (30 Hz) of
rated speed.

• Keep the flow velocity above 1 m/sec.

• Let the pump run at rated speed at least once a day in order to
prevent sedimentation in the piping system.

• Do not exceed the frequency indicated on the nameplate.
In this case there is risk of motor overload.

• Keep the motor cable as short as possible. The peak voltage
will increase with the length of the motor cable. See data sheet
for the frequency converter used.

• Use input and output filters on the frequency converter.
See data sheet for the frequency converter used.

• Use screened motor cable if there is a risk that electrical noise
can disturb other electrical equipment. See data sheet for the
frequency converter used.

8.3.3 Consequences

When operating the pump via a frequency converter, please be
aware of these possible consequences:

• The locked-rotor torque will be lower. How much lower will
depend on the frequency converter type. See the installation
and operating instructions for the frequency converter used for
information on the locked-rotor torque available.

• The working condition of bearings and shaft seal may be
affected. The possible effect will depend on the application.
The actual effect cannot be predicted.

• The acoustic noise level may increase. See the installation
and operating instructions for the frequency converter used for
advice as to how to reduce the acoustic noise.

9. Startup

Proceed as follows:

1. Lock the mains switch in position 0.

2. Check the oil level in the oil chamber. See section 10.1 Oil

check and oil change.

3. Check whether the impeller can rotate freely.

4. Check whether the monitoring units, if used, are operating
satisfactorily.

5. Open the isolating valves, if fitted.

6. Pumps in installation types S and C: Ensure visually that
the pump is properly connected to the auto coupling.

7. Make sure that the pump is submerged in the liquid.
Pumps in installation types D and H: Make sure that there
is liquid in the pit and that the pump housing and cooling
jacket are filled with water. Open the air vent valve (pos. 17 in
fig. 1) before or during the startup until water comes out of the
valve. Then close the valve.
Pumps in installation type C: The air vent valve must always
be open, also during operation. Check the setting of the level
switches.

8. Start the pump, and check the pump operation for abnormal
noise or vibrations.

9. After startup, the actual pump duty point must be established
as accurately as possible so that it can be checked whether
the operating conditions are as desired.

The operation of the pump should always take place in
accordance with established routines with scheduled checks of
pump monitoring equipment and accessories (valves, etc.).
Make sure that the pump and equipment settings cannot be
changed by unauthorized persons.

9.1 Checking the direction of rotation

A label with an arrow on the pump housing indicates the correct
direction of rotation. Direction of rotation must be clockwise
when seen from the drive end.
For installation types S, C and ST pumps: Observe the movement
of the pump (jerk) when started. If the pump jerks counter­clockwise, the direction of rotation is correct.

For installation types D and H pumps: Check the duty point.

Warning
Before manual starting or changeover to

automatic control, make sure that no persons are
working on or near the pump.

Warning
Before the first startup and after a long standstill

period, make sure that the pump has been filled
with pumped liquid.

In dry installations with cooling jacket the
cooling jacket must always be filled with pumped
liquid when operating. Ensure this by venting
before the first startup.

Caution

In case of abnormal noise or vibrations from the
pump or other pump or liquid supply failures,
stop the pump immediately. Do not attempt to
restart the pump until the cause of the fault has
been found and the fault corrected.

Caution

The pump may only be started for a few seconds
without being submerged for checking of
direction of rotation.

10. Maintenance and service

Before carrying out maintenance and service, make sure that the
pump has been thoroughly flushed with clean water. Rinse the
pump parts in water after dismantling.

Pumps running normal operation should be inspected once a
year.

The following points should be checked:

• Power consumption

• Oil level and oil condition

See section 10.1 Oil check and oil change.

• Cable entry
Make sure that the cable entry is waterproof, that the cables
are not sharply bent or pinched, and that the cable sheaths
have no visual defects.

• Impeller clearance
Check the impeller clearance. See section 10.2 Inspection and

adjustment of impeller clearance.

• Pump parts
Check the pump housing, etc. for possible wear.
Replace defective parts.

• Ball bearings
Check the shaft for noisy or heavy operation (turn the shaft by
hand). Replace defective bearings.
A general overhaul of the pump is usually required in case of
defective bearings or poor motor function. This work must be
carried out by an authorized service workshop.

10.1 Oil check and oil change

The oil chamber is filled with oil acting as lubricant and coolant for
both mechanical seals.

Low oil level may indicate that the upper mechanical shaft seal is
defective. Contact an authorized service workshop for further
overhaul of the pump and repair, if required.

The oil in the oil chamber can be changed with the pump in either
horizontal or upright position. We recommend that you carry out
the oil change with the pump in horizontal position, if possible,
because in that way it is much easier to drain all the used oil out
of the chamber.

Horizontal position

Proceed as follows:

1. Place the pump in such a position that inspection screw (A) is
pointing upwards.

Fig. 33 Pump with inspection screw (A) upwards

Warning
During maintenance and service, including

transportation to service workshop, always
support the pump by means of lifting chains or
place it in horizontal position to secure stability.

Warning
Before starting work on the pump, make sure that

the mains switch has been locked in position 0.
Make sure that the power supply cannot be

accidentally switched on.
All rotating parts must have stopped moving!

Warning
Maintenance and service must be carried out by

specially trained persons.

Warning
In case of repairs, always use original service

parts from the manufacturer as this ensures
correct dimensions of flame path gaps.

The bolts used in motor must be class A4-80 or
A2-80 according to EN/ISO 3506-1.

Warning
Defective bearings may reduce the Ex safety.

Warning
The maintenance and service work on explosion-

proof pumps must be carried out by Grundfos or
a service workshop authorized by Grundfos.

Note

Check the oil regularly to avoid damage and
breakdown of the pump.

Warning
Lack of oil may cause overheating and damage of

the mechanical seals. The WIO sensor in the oil
chamber will trip the alarm if the oil quality is
poor or there is not enough oil in the oil chamber.

Note

Use oil with viscosity grade SAE 10 W 30 or
SAE 10 W 40.

2. Place a clean container under the pump to collect all the
drained-off oil. Remove screw B and observe the oil level.

3. Check the oil level and take an oil sample to inspect the
condition of the oil. The oil becomes greyish white like milk if it
contains water. In normal operation a small leakage through
the mechanical shaft seals is expected to happen, but if the
water content in the oil is high, this may be the result of a
defective shaft seal.
The oil should be changed if it contains water. Oil not
containing water can be reused.

4. If the oil needs to be changed, remove screw C and allow all
the oil to drain from the chamber into the container.
Emulsified oil must be changed and disposed of.

5. Replace the O-rings, refit screw C and tighten securely.
Fill the oil chamber with oil to the correct level. Refit screws A
and B and tighten securely.

Upright position

Proceed as follows:

1. Identify the screws A, B and C and their positions relative to
each other. See fig. 33.

Fig. 34 Correct oil level of upright pump

2. Proceed as above and use screw B again for indication of the
level of oil in the oil chamber. See fig. 34.

3. When the pump is upright, the oil has to be pumped out of the
oil chamber. Use a suction pump with a flexible suction hose
that can be inserted deep into the oil chamber.

4. Pump out the oil using all the screw holes in turns so as to
reach all sections of the interior of the oil chamber. Collect the
drained oil in a clean container.

5. Replace the O-rings, refit screw C and tighten securely.
Fill the oil chamber with oil to the correct level. Refit screws A
and B and tighten securely.

10.2 Inspection and adjustment of impeller clearance

The correct axial clearance is 1.3 mm ± 0.2. The clearance
should be reset if it is 2.0 mm or more. The method for resetting
the clearance is different for dry-installed pumps, installation
types D and H, and submersible pumps, installation types S, C
and ST. For dry-installed pumps there are two methods.
All methods are described here.

10.2.1 Submersible pumps, installation types S, C and ST

Submersible pumps have a separate, adjustable pump suction
cover which may be shaped as a suction bell. When the pump is
installed or withdrawn, locate the six fastening screws of the
suction cover and the three set screws.

Use a feeler gauge to check the clearance between the impeller
and the suction cover all around the perimeter of the suction
opening. See fig. 35.

If the clearance needs adjustment proceed as follows:

1. Slacken all fastening screws and set screws between suction
cover and pump housing.

2. Use a mallet to tap at the suction cover and close the
clearance.

3. Open the clearance to specified value by turning the three set
screws.

4. Check that the clearance is uniform around the perimeter of
the suction opening.

5. Tighten the fastening screws and check that the clearance is
still uniform.

6. Turn the impeller by hand and check at several points.

Fig. 35 Impeller clearance, installation types S, C and ST

10.2.2 Dry-installed pumps, installation types D and H

The impeller clearance can be inspected and set with the pump
installed on the pump stand and connected to the pipework.
In these pumps, the suction cover is located between pump
housing and outer connection flange at the suction side of the
pump.

Depending on the construction, there are two ways to set the
impeller clearance.

Note

Used oil must be disposed of in accordance with
local regulations.

10.2.3 Pump cleaning and visual inspection

A simple maintenance measure is to clean the pumps at regular
intervals. Lift the pumps out of the wet pit and clean the pumps on
site in the pumping station. Hose down the pump externally using
a high-pressure jet cleaner (maximum pressure 100 bar).
Remove caked dirt from the motor to ensure good heat
conductivity. A mild detergent approved for disposal into the
sewage system may be used. The pumps may be scrubbed,
using a soft brush, if necessary.

Visual inspection of the pump should include the following:

• Search for cracks or other external damage.

• Check the lifting bracket and lifting chain for wear and
corrosion.

• Inspect the motor cables for cracks or lacerations in the
sheath, for kinks or for other damage.

• Inspect visible parts of the cable entry for cracks.

• Check that the cables are firmly connected to the motor top
cover.

• Check all visible screws for self-slackening and tighten, if
necessary.

The pumps are fitted with an air vent valve at the top of the
cooling jacket. The valve may be removed and cleaned, if
necessary. Clean the vent hole before refitting the valve after
cleaning.

10.2.4 Motor cables

Use only cables which are approved by the manufacturer and
suitable for the cable entry as to diameter, number of conductors,
conductor cross section and sheath material.

10.2.5 Cable entry

Secure the cable entry to the motor top cover by tightening the
screws evenly one by one until the cable entry is lying flat against
the top cover.

The minimum bending radius for cables can be found in the
following table:

10.2.6 Spare parts

Damaged motor parts should always be replaced by new and
approved parts. Motor parts must not be reconditioned by
machining, re-tapping, welding, etc.

10.3 Contaminated pumps

If Grundfos is requested to service the pump, Grundfos must be
contacted with details about the pumped liquid, etc. before the
pump is returned for service. Otherwise Grundfos can refuse to
accept to service the pump.

Possible costs of returning the pump are to be paid by the
customer.

However, any application for service (no matter to whom it may
be made) must include details about the pumped liquid if the
pump has been used for liquids which are injurious to health or
toxic.
