Read this document before you install the

product. Installation and operation must

comply with local regulations and accepted

codes of good practice.

1.1 Hazard statements

The symbols and hazard statements below may

appear in Grundfos installation and operating

instructions, safety instructions and service

instructions.

DANGER

Indicates a hazardous situation which, if

not avoided, will result in death or serious

personal injury.

WARNING

Indicates a hazardous situation which, if

not avoided, could result in death or

serious personal injury.

CAUTION

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

Description of the hazard

Consequence of ignoring the warning

• Action to avoid the hazard.

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

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.

2.1.6 Level controller

The level controller supplied with the lifting stations is

either LC 231 or LC 241.

further details.

2.1.7 Inspection cover

The inspection cover enables inspection of the tank

during operation.

Pos. Description

1 Inspection cover

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.
