2. General description
This booklet includes instructions for installation,
operation and maintenance of Grundfos SL1 and
SLV submersible sewage and wastewater pumps
with motors of 0.9 to 1.5 kW. Grundfos SL1 and SLV
sewage pumps are portable and designed for
pumping domestic and industrial sewage and
wastewater.
Two types of pumps are available:
• SL1.50.65 sewage pumps with single-channel
impeller
• SLV.65.65 sewage pumps with Vortex, free-flow
impeller.
The pumps can be installed on an auto-coupling
system or stand freely on the bottom of a tank.
The pumps can be controlled via the Grundfos
LC, LCD 107, LC, LCD 108, LC, LCD 110 pump
controllers or the Grundfos CU 100 control box.
See installation and operating instructions for the
selected controller.

2.2 Applications
SL1.50.65 pumps are designed for pumping these
liquids:
• large quantities of drainage and surface water
• domestic wastewater with discharge from toilets
• wastewater from commercial buildings without
discharge from toilets
• sludge-containing industrial wastewater
• industrial process water.
SLV.65.65 pumps are designed for pumping these
liquids:
• surface water with abrasive particles
• municipal sewage
• sewage from commercial buildings
• sludge- or fibre-containing industrial wastewater.
The compact design makes the pumps suitable for
both temporary and permanent installation.
2.3 Operating conditions
The SL1 and SLV pumps are designed for
intermittent operation (S3). When completely
submerged in the pumped liquid, the pumps can also
operate continuously (S1). See 9.2 Operating
modes.
Installation depth
Maximum 10 metres below liquid level.
Operating pressure
Maximum: 6 bar.
Intermittent operation
Maximum 20 starts per hour.
pH value
SL1 and SLV pumps in permanent installations can
be used for pumping liquids with a pH value between
4 and 10.
Liquid temperature
0 °C to +40 °C.
For short periods (maximum 15 minutes) a
temperature of up to + 60 °C is permissible
(non-Ex versions only).
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.
3. Delivery and handling
The pump may be transported and stored in a
vertical or horizontal position. Make sure that it
cannot roll or fall over.
3.1 Transportation
All lifting equipment must be rated for the purpose
and checked for damage before any attempts to lift
the pump. The lifting equipment rating must under no
circumstances be exceeded. The pump weight is
stated on the pump nameplate.
The polyurethane-embedded plug prevents water
from penetrating into the motor via the motor cable.
3.2 Storage
During long periods of storage, the pump must be
protected against moisture and heat.
After a long period of storage, the pump should be
inspected before it is put into operation. Make sure
that the impeller can rotate freely. Pay special
attention to the condition of the shaft seals and the
cable entry.
Warning
Explosion-proof pumps must never
pump liquids with a temperature higher
than +40 °C.
Warning
Always lift the pump by its lifting
bracket or by means of a fork-lift truck
if the pump is fixed on a pallet. Never
lift the pump by means of the motor
cable or the hose/pipe.

4. Identification
4.1 Nameplate
The nameplate states the operating data and
approvals applying to the pump. The nameplate is
fixed with rivets to the side of the motor housing
close to the cable entry.
Fix the additional nameplate supplied with the pump
close to the tank.
