Product introduction
This booklet includes instructions for installation,
operation and maintenance of Grundfos SL1 and
SLV submersible sewage and wastewater pumps
with motors of 1.1 to 11 kW. Grundfos SL1 and SLV
sewage and wastewater pumps are designed for
pumping domestic, municipal and industrial sewage
and wastewater.
Two types of pumps are available:
• SL1 sewage pumps with S-tube impeller
• SLV sewage pumps with SuperVortex free-flow
impeller.
The pumps can be installed on an auto-coupling
system or stand freely on the bottom of a tank.
Grundfos SL1 and SLV pumps are designed with
S-tube or SuperVortex impellers to ensure reliable
and optimum operation.
The booklet also includes specific instructions for the
explosion-proof pumps.

Pumped liquids and intended use
SL1 and SLV pumps are designed for pumping these
liquids:
• large quantities of drainage and surface water
• domestic wastewater with discharge from toilets
• wastewater with a high content of fibres
(SuperVortex impeller)
• municipal and commercial sewage and
wastewater.
Operating conditions
SL1 and SLV pumps are suitable for the following
operating situations:
•S1 operation (continuous operation), the pump
must always be covered by the pumped liquid to
the top of the motor.
•S3 operation (intermittent operation), the pump
must always be covered by the pumped liquid up
to the top of the cable entry.
pH values
SL1 and SLV pumps in permanent installations can
be used for pumping liquids with the following pH
values:
1) For fluctuating pH values, the range is pH 4 to
14.
Liquid temperature
0-40 °C.

Density and viscosity of pumped liquid
When pumping liquids with a density and/or a
kinematic viscosity higher than that of water, use
motors with correspondingly higher outputs.
Identification
Nameplate
The nameplate states the operating data and
approvals applying to the pump. The nameplate is
fitted to the side of the motor housing close to the
cable entry.
Fix the extra nameplate supplied with the pump to
the cable end in the control cabinet.
Fig. 2 Nameplate
Explosion-proof pumps must never pump
liquids of a temperature higher than +40
°C.
For explosion-proof pumps, the ambient
temperature on the installation site must
be in the range from -20 °C to +40 °C.
For explosion-proof pumps with WIO
sensor, the ambient temperature on the
installation site must be in the range from
0-40 °C.

CAUTION
Crushing hazard
Minor or moderate
personal injury
- Make sure the pump
cannot roll or fall over.
WARNING
Crushing hazard
Death or serious
personal injury
- Always lift the pump by
its lifting bracket or by
a forklift truck if the
pump is fixed on a
pallet. Never lift the
pump by the power
cable, hose or pipe.

Safety
Potentially explosive environments
Pump installation in
tanks must be carried
out by specially trained
persons.
Work in or near tanks
must be carried out
according to local
regulations.
Persons must not work in the installation
area when the atmosphere is potentially
explosive.
WARNING
Crushing hazard
Death or serious
personal injury
- Make sure that the
lifting bracket is
tightened before lifting
the pump.
Carelessness during
lifting or transport may
cause injury to persons
or damage to the
pump.
WARNING
Electric shock
Death or serious
personal injury
- Connect the pump to
an external main
switch which ensures
all-pole disconnection
with a contact
separation according
to EN 60204-1. It must
be possible to lock the
main switch in position
0. The electrical
connection must
comply with local
regulations.
SL1 and SLV pumps must under no
circumstances be used to pump explosive,
flammable or combustible liquids.
The classification of the installation site
must be approved by the local fire-fighting
authorities.
English (GB)

Mechanical installation
Special conditions for safe use of SL1 and
SLV explosion-proof pumps:
1. Make sure the moisture switch and
thermal switches are connected in the
same circuit but have separate alarm
outputs (motor stop) in case of high
humidity or high temperature in the
motor.
2. Bolts used for replacement must be
class A2-70 or better according to
EN/ISO 3506-1.
3. Contact the manufacturer for
information on the dimensions of the
flameproof joints.
4. The level of pumped liquid must be
controlled by two level switches
connected to the motor control circuit.
The minimum level depends on the
installation type and is specified in
these installation and operating
instructions.
5. Make sure the permanently attached
cable is suitably mechanically
protected and terminated in a suitable
terminal board placed outside the
potentially explosive area.
6. The sewage pumps have an ambient
temperature range of -20 °C to +40 °C
and a maximum process temperature
of +40 °C. The minimum ambient
temperature for a pump with a
water-in-oil sensor is 0 °C.
7. The thermal protection in the stator
windings has a nominal switch
temperature of 150 °C and must
guarantee the disconnection of the
power supply. The power supply must
be reset manually.
8. The control unit must protect the WIO
sensor against short circuit current of
the supply to which it is connected. The
maximum current from the control unit
must be limited to 350 mA.
9. In case of frequency converter usage,
the maximum surface temperature of
the pump can be 200 °C.
10. The WIO sensor is intended for use
only with a galvanically isolated circuit.
11. The lock nut of the cable connector
must only be replaced with an identical
one.
12. The WIO sensor must be connected
according to these installation
instructions.
EX pumps are equipped with a WIO
sensor optionally.
Compliance with the standard EN
60079-14 is a customer responsibility.
WARNING
Body injury
Death or serious
personal injury
- Pump installation in
tanks must be carried
out by specially trained
persons. Work in or
near tanks must be
carried out according
to local regulations.
Persons must not work in the installation
area when the atmosphere is potentially
explosive.
WARNING
Crushing hazard
Death or serious
personal injury
- During installation,
always support the
pump by lifting chains
or place it in horizontal
position to secure
stability.
English (GB)
9
WARNING
Electric shock
Death or serious
personal injury
- Before beginning the
installation, switch off
the power supply and
lock the main switch in
position 0.
- Make sure that the
power supply cannot
be switched on
unintentionally.
- Any external voltage
connected to the pump
must be switched off
before working on the
pump.
WARNING
Crushing of hands
Death or serious
personal injury
- Do not put your hands
or any tool into the
pump inlet or outlet
port after the pump is
connected to the power
supply, unless the
pump has been
switched off by
removing the fuses or
switching off the main
switch. Make sure that
the power supply
cannot be switched on
unintentionally. Make
sure that all the
rotating parts have
stopped moving.
CAUTION
Crushing hazard
Minor or moderate
personal injury
- Use the lifting bracket
only for lifting the
pump. Do not use it to
hold the pump in
operation.

Installation types
Fig. 4 Submerged installation on auto coupling
SL1 and SLV pumps are designed for two installation
types:
• submerged installation on auto coupling
• free-standing submerged installation on ring
stand.

Grade 4.6 (5) galvanised steel screws and nuts
TM04 2650 2808
Before beginning installation procedures,
make sure that the atmosphere in the tank
is not potentially explosive.
Inspect the oil level and condition every
3000 operating hours or at least once a
year.
When the pump is new or after
replacement of the shaft seal, check the oil
level and water content after one week of
operation.
