Warnin g
During installation, always support the pump by

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

Warnin g
Before beginning the installation, switch off the

power supply and lock the mains switch in
position 0.

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

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.

Warnin g
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
pump has been switched off by removing the
fuses or switching off the mains switch. Make
sure that the power supply cannot be accidentally
switched on.

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

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
the flanges.

Permanent, vertical installation in a pit

The pump can easily be pulled out of and lowered into the pit via
the guide rails. See fig. 5. The liquid level can be set lower for
installation type C than for type S. See fig. 1.

8.2 Permanent, vertical, submerged installation in a pit

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

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
the flanges.

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

In some installations, a plinth is required beneath
the auto coupling to ensure correct installation of
the pump. This should be considered during the
design of the installation.

Proceed as follows:

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.

4. Place the guide rails on the auto-coupling base unit and adjust

the length of the rails accurately to the guide-rail bracket at
the top of the pit.

5. Unscrew the provisionally fastened guide-rail bracket. Insert

the expansion dowels into the holes. Fasten the guide-rail
bracket on the inside of the pit. Tighten the bolts in the
expansion dowels.

The guide rails must not have any axial play as
this would cause noise during pump operation.

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

7. Fit the guide claw to the pump.

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

9. 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 housing.

10. Adjust the length of the motor cable by coiling it up on a relief
fitting to ensure that the cable is not damaged during
operation. Fasten the relief fitting to a suitable hook at the top
of the pit. Make sure that the cables are not sharply bent or
pinched.

11. Connect the motor cable and the control cable, if any.

TM05 2539 0212

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

room.

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

Proceed as follows:

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

2. Fit the bracket or base stand to the pump.

3. Fasten the pump with expansion bolts.

4. Check that the pump is vertical/horizontal.

In order to facilitate service on the pump, we recommend that you
use 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 cable by coiling it up on a relief
fitting to ensure that the cable is not damaged during
operation. Fasten the relief fitting to a suitable hook. Make
sure that the cables are not sharply bent or pinched.

7. Connect the motor cable and the control cable, if any.

8.4 Temporary, vertical, submerged installation in a pit

Proceed as follows:

1. Fit the ring stand to the pump suction flange.

2. Fit a 90 ° elbow to the pump discharge port and connect the
discharge pipe/hose.
If a hose is used, make sure that the hose does not buckle
and that the inside diameter matches that of the discharge
port.

3. Lower the pump into the liquid by means of a chain secured to
the lifting bracket of the pump. We recommend that you place
the pump on a plane, solid foundation.

During lowering, make sure that the pump is
hanging from the chain and not the cable.

4. When the pump is placed firmly on the bottom of the pit,
attach the end of the chain to a suitable hook at the top of the
pit and in such a way that the chain cannot come into contact
with the pump housing.

5. Adjust the length of the motor cable by coiling it up on a relief
fitting to ensure that the cable is not damaged during
operation. Fasten the relief fitting to a suitable hook. Make
sure that the cables are not sharply bent or pinched.

6. Connect the motor cable and the control cable, if any.

8.5 Pump controllers

SE, SL pumps, 9-30 kW, can be connected to one of the following
Grundfos pump controllers for level control. The controllers are
available as accessories.

• Type LC for one-pump installations

• Type LCD for two-pump installations

• Grundfos Dedicated Controls for one to six pumps.
Depending on the type of controller used, different types of level

control equipment can be used:
The LC controller is fitted with two or three level switches. Two

for start and stop of the pump. The third level switch, which is
optional, is for high-level alarm.

The LCD controller is fitted with three or four level switches. One
for common stop and two for start of the pumps. The fourth level
switch, which is optional, is for high-level alarm.

Grundfos Dedicated Controls is a control system designed for
installation in either commercial buildings or network pumping
stations with up to six pumps. Advanced control and data
communication is also possible with the Grundfos Dedicated
Controls system.

The Dedicated Controls system consists of the following
components:

• CU 361 control unit

• IO 351B module (general I/O module)

• IO 113 protection module (optional).
The Dedicated Controls system starts/stops the wastewater

pumps by means of the following devices:

TM05 2540 0212

• float switches

• analogue pressure sensors

• ultrasonic sensors.
Furthermore, it is possible to control the liquid level by combining

float switches with an analogue pressure sensor. Two additional
safety float switches can be installed in the Dedicated Controls
system for high-level and dry-running alarm.

When installing the level switches, please observe the following
points:

• To prevent air intake and vibrations in submerged pumps, fit
the stop level switch in such a way that the pump is stopped
before the liquid level is lowered below the top of the pump
housing. As a principal rule for pumps in dry installation, the
lowest stop level must be at least 20 cm above the opening of
the suction pipe. See fig. 9.

• Install the start level switch in such a way that the pump is
started at the required level; however, the pump must always
be started before the liquid level reaches the bottom inlet pipe
to the pit.

• If used, always install the high-level alarm switch about 10 cm
above the start level switch; however, alarm must always be
given before the liquid level reaches the bottom inlet pipe to
the pit.

Warnin g
The pump controller must not be installed in

potentially explosive atmospheres.

English (GB)

Warning
Do not let the pump run dry.
Install an additional level switch to ensure that

the pump is stopped in case the stop level switch
is not working.

9. Electrical connection

Note

Caution

English (GB)

Warnin g
The pump must be connected to an external

mains switch with a contact separation according
to EN 60204-1, 5.3.2.

The electrical connection must be carried out in
accordance with local regulations.

The supply voltage and frequency are marked on the pump
nameplate.

The voltage tolerance at the motor terminals must be within - 10
%/+ 10 % of the rated voltage.

Make sure that the motor is suitable for the power supply
available at the installation site.

The motor is effectively earthed via the power cable and
pipework.

9.1 Sensors

SE, SL pumps, 9-30 kW, can be equipped with a variety of
switches and sensors for protection. The specification table
below shows which switch and sensor types can be used for
which pump types.

The wiring diagrams of the various types of switch and sensor
appear from fig. 16 to fig. 22 in section 13. Sensor overview.

Warnin g
Maintenance and service work on

explosion-proof pumps must be carried out by
Grundfos or a service workshop authorised by
Grundfos.

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

Warnin g
Before installation and the first startup of the

pump, check the condition of the cable visually to
avoid short circuits.

The most commonly used startup methods are these:

• direct-on-line starting (DOL). See appendix, fig. 2.

• star-delta starting (Y/D). See appendix, fig. 1.

• soft start.
The pump can even be started via a frequency converter

according to the frequency converter manufacturer's
specifications. See section 9.5 Frequency converter operation.
The selection of suitable starting method depends on several
considerations on usage and mains supply conditions.

When using star-delta starting, it is important to
keep switching transient time to a minimum to
avoid high transient torques. We recommend that
you use a time relay with a switching time of
maximum 50 ms or according to the starter
manufacturer's specifications.

9.2 Thermal switches

Three bimetallic thermal switches are built into the stator
windings, and they will open in case of overtemperature.

The supply voltage to the thermal switches must be 12-230 VAC.
The thermal switches are connected to the control cable, and

must be connected to the safety circuit of the separate pump
controller.

The motor-protective circuit breaker of the pump
controller must include a circuit which
automatically disconnects the power supply in
case the protective circuit for the pump is
opened.

Warning
The installer/user must install an automatic

circuit breaker which disconnects the power
supply in case the thermal switches or the
moisture switches are not working.

12

9.3 Moisture and leakage switches

Note





Non-Ex version:

There is one moisture switch and one leakage switch mounted in
a non-Ex pump. The moisture switch is placed in the top cover
and the leakage switch is placed in the chamber above the shaft
seal. See appendix, fig. 3, section C-C and E-E.

Ex version:

There is one moisture switch and one leakage switch mounted in
an Ex pump. The moisture switch is placed in the top cover and
the leakage switch is placed in the stator housing. See appendix,
fig. 3, section C-C and D-D.

All switches in both non-Ex and Ex versions are hardwired from
the pump to IO 113. If moisture or a leakage is detected, they will
break an electric circuit. This will generate both a hardware and a
software alarm in IO 113, and the alarm relay will open.

Moisture and leakage switches are motor protection devices,
which protect the motor from damage due to moisture or water
ingress. The switches are of a non-reversing type and must be
replaced after they have been released.

The moisture and leakage switches are connected in a separate
circuit and to the control cable. See section 9. Electrical

connection. They are also to be connected to the safety circuit of

the separate pump controller.

9.4 Thermistors

Thermistors are available as an accessory or as an FPV (Factory
Product Variant) option.

The thermistors can be used as motor protection devices to
monitor stator temperature in stead of thermal switches and must
be connected to the thermistor relay in the control cabinet.

The operating voltage of PTC thermistors is 2.5 - 7.5 V.

Checking after installation of pumps

1. Using a multimeter, check whether the circuit resistance is
lower than 150 Ω per thermistor.

2. Using a multimeter, check whether the insulation between
circuit and stator housing is outside the scale (not measurable

).

3. Carry out a similar measurement at the end of the power
supply cable.

9.4.1 Pt1000 temperature sensor

The Pt1000 temperature sensor is available as an accessory or
as an FPV (Factory Product Variant) option.

The Pt1000 sensor is primarily used for the monitoring of bearing
temperature, but it can also be used in the stator.

In case of overheating caused by wear, lack of lubricant, etc., the
Pt1000 sensor will trip an alarm and disconnect the power supply
at a preset temperature.

The bearing temperature monitoring is only
available as an option.

The sensor resistance is this:

• 1000 Ω at 0 °C

• 1385 Ω at 100 °C

• approx. 1078 Ω at room temperature.

The following temperature limits are used for SE, SL, pumps 9-30
kW:

• 90 °C: warning for high bearing temperature

• 130 °C: pump stop caused by high bearing temperature

• 150 °C: pump stop caused by high stator temperature.

Warnin g
In Ex-approved pumps the maximum acceptable

alarm temperature in bearing sensors is 100 °C
for the lower bearing (shaft end) and 120 °C for
the upper bearing.

Checking after installation of pump

1. Using a multimeter, check whether the resistance at room
temperature (20 °C) is approx. 1078 Ω.

2. Using a multimeter, check whether the insulation between
circuit and stator housing is outside the scale (not measurable

).

3. Carry out similar measurements at the end of the power
supply cable.

During pump check, the Pt1000 sensor must be connected to a
recording device.

9.4.2 Pump vibration sensor (PVS 3)

The PVS 3 sensor monitors the vibration level of the pump in
order to protect the pump and the pipe system against damage.

A change in the vibration level is an indication of an abnormal
situation. The reason for this can be a clogged impeller, worn
bearings, closed discharge valve, etc. indicating that a service
inspection should be carried out before the pump or the pipe
system is damaged

9.4.3 SM 113

SM 113 is used for collecting and transferring sensor data. SM
113 works together with IO 113 through power line
communication using the Grundfos GENIbus protocol.

SM 113 collects data from the following devices:

• 3 current sensors, 4-20 mA

• 3 Pt1000 thermal sensors

• 1 thermistor circuit (3 sensors in series)

• 1 digital input.

9.4.4 IO 113

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

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

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

IO 113 enables the following functions:

• protection of the pump against overtemperature

• monitoring the sensors for analogue measurement of the

following:

– motor temperature
– pump vibrations
– stator insulation resistance
– bearing temperature
– moisture in motor.

• stopping the pump in case of alarm

• remotely monitoring the pump via RS485 communication

(Modbus or GENIbus).

English (GB)

9.4.5 Measurement of insulation resistance

Note

English (GB)

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.

9.5 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.

9.5.1 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.

Maximum repetitive peak

voltage

[V]

850 2000

• 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.

9.5.2 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 (S1) to less than 30 Hz.

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

9.5.3 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.

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

11. 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 pump may only be started for a very short
period without being submerged for checking of
direction of rotation.

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
unauthorised persons.

Warnin g

Warnin g
Do not open the pump if the ambient atmosphere

is explosive or dusty.

Maintenance and service must be carried out by specially trained
persons.

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 every 2000
operating hours or at least once a year. If the pumped liquid is
very muddy or sandy, the pump should be inspected every 1000
operating hours or every six months.

The following points should be checked:

• power consumption

• motor liquid level.
When the pump is new or after replacement of the shaft seals,

check the motor liquid level and its water content after one week
of operation. If the motor liquid level has dropped, the shaft seal
may be defective. See section 11.1 Checking and changing the

motor liquid.

Dispose of the motor liquid in accordance with
local regulations.

Warning
The ball bearings must be replaced at least every

36,000 operating hours.

11.1 Checking and changing the motor liquid

Clean the outside of the pump at regular intervals
in order to retain the heat conductivity.

Change the motor liquid every four years to
prevent oxidation.

11.1.2 Pump without cooling jacket (SL pumps)

The shaft seal housing has two plugs as shown in figs 10 and 11.
Plug A is for checking the level of motor liquid and for filling motor

liquid into the shaft seal housing.
Plug B is for draining motor liquid from the shaft seal housing.

Fig. 10 Checking motor liquid level, pump in vertical

installation

Warning
Lack of motor liquid may cause overheating and

damage of the mechanical seals.

Warning
Use cooling liquid SML3 for motor cooling.

Cooling liquids with lower specific heat capacity
than SML3 may cause overheating of the motor.

11.1.1 Checking the motor liquid

It is possible to check the ingress level of pumped liquid into the
motor liquid. Use a refractometer (product no. 98676968) which
will show the refractive index in percent of ingress.

Liquid ingress refractive index in %:
0 %: -30 °C.
5 %: -27 °C.
10 %: -25 °C.
15 %: -23 °C.
20 %: -22 °C.

If the refractive index is higher than -22 °C, change the motor
liquid.

We recommend that you do not exceed this level of refractive
index in order to ensure that the shaft seal and the bearings are
in the best possible condition for reliable operation. For further
information, see service instruction for SE, SL pumps.

Fig. 11 Checking motor liquid level, pump in horizontal

installation

There must be minimum of 10 % air in the seal
housing due to thermal expansion of the motor
liquid during operation.

The motor liquid level can be checked by removing plug A either
in vertical or horizontal position. See figs 10 and 11.

Draining motor liquid

Place a container under the pump to collect all the drained-off
motor liquid. Tip the pump to a horizontal position so that plug B
is pointing downwards. See fig. 11. Due to possible pressure
build-up in the shaft seal housing, open plug A cautiously and
then remove plug B. Allow all the motor liquid to drain from the
housing into the container.

Warnin g

conductor cross section and sheath material.

11.3.2 Cable entry

Use only Ex cable entry parts corresponding to the cable
diameter. The corresponding cable dimension marking is
stamped on the inlet or the cable entry.

11.3.3 Spare parts

Damaged motor parts, such as top cover and cable entry, should
always be replaced by new and approved parts. Motor parts must
not be reconditioned by machining, re-tapping, welding, etc.

11.4 Contaminated pumps

Warnin g
If a pump has been used for a liquid which is

injurious to health or toxic, the pump will be
classified as contaminated.

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 the pump for service.

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.
