2. General description
This booklet includes instructions for installation, operation and
maintenance of Grundfos SE1 and SEV submersible sewage and
wastewater pumps with motors of 1.1 to 11 kW. Grundfos SE1
and SEV sewage and wastewater pumps are designed for
pumping domestic, municipal and industrial sewage and
wastewater.
Two types of pumps are available:
• SE1 pumps with S-tube impeller
• SEV pumps with SuperVortex impeller.
The pumps can be installed on an auto-coupling system or stand
freely on the bottom of a pit. They can even be dry-installed in
either vertical or horizontal position.
Grundfos SE1 and SEV pumps are designed with an S-tube and
SuperVortex impeller, respectively, to ensure reliable and
optimum operation.
The booklet also includes specific instructions for the explosion-
proof pumps.

Fig. 1 SE pump
2.2 Control and monitoring
The pumps can be controlled via the Grundfos controllers LC,
LCD 107, LC, LCD 108, LC, LCD 110 and DC, DCD.
Pumps with a sensor are supplied together with an IO 111 or
IO 113 which can receive signals from the following transmitters:
• water-in-oil-sensor (WIO sensor) in the pump
• moisture sensor in the motor
• temperature sensor in the stator windings
• winding resistance sensor in the motor.
For further information, see installation and operating instructions
for the specific sensor.
2.3 Applications
SE1 and SEV 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)
• industrial wastewater
• wastewater with gaseous sludge
• municipal and commercial sewage and wastewater.
SE1 and SEV pumps are ideal for installation in locations such
as:
• public buildings
• blocks of flats
• industry
• garages
• multi-storey car parks
• vehicle washing tunnels
• restaurants.
Stainless steel versions
Stainless steel versions are further more suitable for the following
applications:
• industrial process water containing chemicals
• aggressive or corrosive drain water and effluent
• abrasive particles in wastewater
• wastewater contaminated with seawater.
The compact design makes the pumps suitable for both
temporary and permanent installation.
2.4 Pump selection
The table below shows which pump version to select for a
number of liquids:
Impeller type: 1 = S-tube impeller, V = SuperVortex impeller.

2.5 Operating conditions
The Grundfos SE1 and SEV pumps are suitable for the following
operating situations:
•Dry installation without separate motor cooling
arrangements.
•Submerged installation
S1 operation (continuous operation)
pH value
SE pumps in permanent installations can cope with the following
pH values:
1) Cast iron impeller, pump housing and motor top.
2) Stainless steel impeller. Cast iron pump housing and motor
top.
3) Stainless steel impeller and pump housing. Cast iron motor
top. Material variant S is available on request.
4) Entire pump in stainless steel.
5) Stainless steel pump according to EN 1.4517/1.4539.
Material variant D is available on request.
6) For fluctuating pH values, the range is pH 4 to 14.
Liquid temperature
0 °C to +40 °C.
For short periods (maximum 1 hour) a temperature of up to 60 °C
is permissible (non-Ex versions only).
Ambient temperature
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.
Flow velocity
It is advisable to keep a minimum flow velocity to avoid
sedimentations in the piping system. Recommended flow
velocities:
- in vertical pipes: 1.0 m/s
- in horizontal pipes: 0.7 m/s
Maximum solids size
From 50 to 100 mm, depending on pump size.
Operating mode
Maximum 20 starts per hour.
S1, continuous operation. The pump can operate continuously
without having to be stopped for cooling.
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 moisture from
penetrating into the motor via the motor cable.
3.2 Storage
During long periods of storage, the pump must be protected
against moisture, heat and cold.
Storage temperature: -30 °C to +60 °C.
If the pump has been in use, the oil should be changed before
storage. See section 10.2.1 Oil change.
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
seal, O-rings, oil and the cable entry.

Warning
Explosion-proof pumps must never pump liquids of a
temperature higher than +40 °C.
Warning
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 at the installation site must be
in the range from 0 °C to +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.
Warning
If the pumps are stored for more than one year or it
takes a long time before it is put into operation after
the installation, the impeller must be turned at least
once a month.
