Indicates a hazardous situation which, if
not avoided, could result in minor or
moderate personal injury.
The hazard statements are structured in the following
way:
SIGNAL WORD

English (GB)
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
may result in malfunction or damage to the
equipment.
Tips and advice that make the work easier.
2. Product introduction
2.1 Product description
2.1.1 Tank
The gas-, odour- and pressure-tight tank is made of
resistant polyethylene. The tank has all necessary
ports for the connection of inlet pipes, outlet pipe,
vent pipe and a manually operated diaphragm pump
available as an accessory.
Inside the tank the two pump connections are
connected to a suction bend enabling suction from
the bottom. As a result, the residual volume is
reduced to a minimum.
The table below shows the tank volume and the
effective volume. The effective volume is the volume
between start and stop.
Number of tanks 1 2 3
Tank volume [l] 450 900 1350
Effective volume with
stop delay [l] 225 450 675
Effective volume without
stop delay [l] 150 300 450
2.1.2 Pumps
The pumps are standard wastewater pumps with
supporting feet for horizontal installation. The pumps
come in two versions:
MULTILIFT
system Pump version
MD1 SE1, SL1 pump with single-
channel impeller
MDV SEV, SLV pump with SuperVortex
impeller
6
English (GB)
2.1.3 Operating modes
SE pumps
• Continuous operation: The pump runs
continuously.
• Intermittent operation: Within a duty cycle of 1
minute, the pump must be stopped for 30 seconds
to cool down.
SL pumps
• Intermittent operation: Within a duty cycle of 1
minute, the pump must be stopped for 30 seconds
to cool down. The maximum ambient temperature
is 30 °C.
We recommend maximum 30 starts per hour for both
pump types. However, 60 starts per hour within a two-
hour period at peak load are allowed. The purpose is
to minimise wear of the shaft seal, bearings and
motor.
For further information, see the installation and
operating instructions for the pumps.
2.1.4 Motor protection
A thermal switch is incorporated in the motor
windings. A motor-protective circuit breaker is
incorporated in the control cabinet, and the controller
has an additional current measurement function.
2.1.5 Level sensor
The level sensor consists of a piezoresistive pressure
sensor and a pressure tube connected by a pressure
hose. The pressure tube is located underneath the
screw cap and extends down into the tank. The screw
cap includes a condensate trap and a connection for
the tube. You can remove the pressure tube for
maintenance, service and cleaning. The pressure
sensor measures the liquid level in the tank. The
rising liquid level compresses the air inside the
pressure tube and hose, and the piezoresistive
pressure sensor transforms the changing pressure
into an analog signal. The controller uses the analog
signal to start and stop the pump and to indicate high-
level alarm.

2.1.8 Non-return valve
Lifting stations must be provided with an approved
non-return valve according to EN 12050-4. The non-
return valve must have a correct free passage and a
lifting device, for example a screw, to drain the outlet
pipe back into the tank.

3.2 Scope of delivery
2.1.9.2 Drainage pump
If the lifting station is installed in a basement with
penetrating groundwater, we recommend that you
install a drainage pump in a separate pump sump
below floor level. In some countries, a drainage pump
or only a pump sump is required.

English (GB)
2.2 Applications
The product is designed for the collection and
pumping of wastewater with no free flow to sewer
level. Typically the product is installed below sewer
level in cellars or basements in buildings such as:
• large-scale multifamily houses
• public and commercial buildings
• blocks of flats
• schools
• offices
• hotels
• restaurants
• hospitals
• industries.
2.3 Pumped liquids
The product is designed for the collection and
pumping of these liquids:
• wastewater
• sludge-containing water
• domestic wastewater containing faecal matter.
The free passage of the product enables pumping of
liquids containing solids from 65 to 80 mm in
diameter, depending on the pump type.
Do not discharge these substances or types of
wastewater via the product:
• Solid matter, tar, sand, cement, ash, coarse paper,
paper towels, cardboard, debris, garbage, grease
and oil.
• Wastewater from sanitary installations situated
below the backflow level must be drained away
via a free-flow drainage system according to EN
12056-1.
• Wastewater containing hazardous substances
such as greasy wastewater from large-scale
catering establishments.
For drainage of greasy wastewater, use a grease
separator according to EN 1825.
• Rainwater of large areas outside the building, for
example parking lots, must be collected and
discharged outside the building with separate
pumping stations.
