English (GB)

The hazard statements are structured in the following
way:
SIGNAL WORD
Description of the hazard
Consequence of ignoring the warning
• Action to avoid the hazard.
1.2 Notes
The symbols and notes below may appear in
Grundfos installation and operating instructions,
safety instructions and service instructions.
Observe these instructions for explosion-
proof products.
A blue or grey circle with a white graphical
symbol indicates that an action must be
taken.
A red or grey circle with a diagonal bar,
possibly with a black graphical symbol,
indicates that an action must not be taken
or must be stopped.
If these instructions are not observed, it

intended for professional installers.
2. Product introduction
2.1 Product description
This manual includes instructions for installation,
operation, and maintenance of Grundfos SL1 and
SLV submersible sewage and wastewater pumps
with 1.1 to 11 kW motors. The pumps are designed
for pumping domestic, municipal, and industrial
sewage and wastewater.
The following pump types 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 manual also includes specific instructions for the
explosion-proof pumps.

2.2 Pumped liquids and intended use
SL1 and SLV pumps are designed for pumping
the following:
• 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.
2.3 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:

6-141)
1) For fluctuating pH values, the range is pH 4 to 14.
Liquid temperature
0-40 °C
For non-explosion-proof pumps, a temperature of up
to 60 °C is permissible for short periods (maximum 3
minutes).
Ambient temperature
-20 to +40 °C
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 of -20 °C to +40 °C.
For explosion-proof pumps with a WIO
sensor, the ambient temperature on the
installation site must be in the range of
0-40 °C.
For non-explosion-proof pumps, the ambient
temperature may exceed +40 °C for a short period
(maximum 3 minutes).
Density and viscosity of the pumped liquid
When pumping liquids with a density and/or a
kinematic viscosity higher than water, use motors with
correspondingly higher outputs.
Flow
velocity
Keep a minimum flow velocity to avoid
sedimentation in the piping system.
Recommended flow velocities:
in vertical pipes: 0.7 m/s
in horizontal pipes: 1.0 m/s.
Free
spherical
passage
From 50 to 100 mm, depending on
pump size.
Operating
mode Maximum 20 starts per hour.

2.4 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.
