submersible sewage pumps and submersible motor
pumps should be stored horizontally or vertically. It
should be ensured that they cannot bend if stored
horizontally.
Danger from falling over!
Never put down the product unsecured. If the
product falls over, injury can occur!
•
The product has to be stored at a place free from vi-
brations and agitation to avoid damage from the ball
bearings.
•
It is also necessary to pay attention to the storage.
The device should be stored in dry rooms without
temperature fluctuation.
•
The product may not be stored in rooms where wel-
ding work is conducted as the resulting gases and ra-
diation can damage the elastomer parts and coatings.
•
It is responsible to take care that the corrosion coa-
ting will not be spoiled
•
Any suction or pressure connections on products
should be closed tightly before storage to prevent
impurities.
•
The power supply cables should be protected against
kinking, damage and moisture.
Beware of electrical current!
Damaged power supply cables can cause fatal in-
jury! Defective cables must be replaced by a quali-
fied electrician immediately.
Beware of damp!
Moisture penetrating cables can damage them and
render them useless. Therefore, never immerse cab-
le ends in the pumped fluid or other liquids.
•
The machine must be protected from direct sunlight,
heat, dust, and frost. Heat and frost can cause con-
siderable damage to propellers, rotors and coatings.
•
The rotors or propellers must be turned at regular in-
tervals. This prevents the bearing from locking and
the film of lubricant on the mechanical shaft seal is re-
newed. This also prevents the gear pinions (if present
on the product) from becoming fixed as they turn and
also renews the lubricating film on the gear pinions
(preventing rust film deposits).
Beware of sharp edges!
Sharp edges can form on rotors and propellers.
There is a risk of injuries. Wear protective gloves.
•
If the product has been stored for a long period of
time it should be cleaned of impurities such as dust
and oil deposits before start-up. Rotors and propellers
should be checked for smooth running, housing coa-
ting and damage.
•
After storage longer than one year the oil of motor
and, if necessary the gear have to be changed. This
is also necessary if the product never had run (natural
deterioration of mineral oil).
Before start-up, the filling levels (oil, cooling fluid etc.)
of the individual products should be checked and top-
ped up if required. Please refer to the machine data
sheet for specifications on filling. Damaged coatings
should be repaired immediately. Only a coating that

is completely intact fulfills the criteria for intended
usage!
If these rules are observed, your product can be stored
for a longer period. Please remember that elastomer parts
and coatings become brittle naturally. If the product is
to be stored for longer than 6 months, we recommend
checking these parts and replacing them as necessary.
Please consult the manufacturer.
4.4. Returning to the supplier
Products which are delivered to the plant must be clean
and correctly packaged. In this context, clean means
that impurities have been removed and decontaminat-
ed if it has been used with materials which are hazard-
ous to health. The packaging must protect the product
against damage. Please contact the manufacturer before
returning!
5. Installation and Start-Up
5.1. General
In order to prevent damage to the pump or serious injury
during installation the following points must be observed:
•
Installation work may only be carried out by qualified
persons. The safety instructions must be followed at
all times.
•
The pump must be inspected for damages before any
installation work is carried out.
•
If you are using level control, make sure that the
minimum water coverage is present.
•
Air pockets may not be allowed to enter the pump
housing or the pipes and they must be removed with
a suitable ventilation system or a small inclination of
the pump.
•
Protect the pump from frost.
•
The operating area must be laid out for each machine.
You must ensure that lifting gear can be fitted without
any trouble, since this is required for assembly and
removal of the machine.
•
The maximum bearing capacity must be greater than
the weight of the machine, add-on units and cable.
•
Electric power cables must be laid out in such a way
that safe operation and non-problematic assembly/
dismantling are possible at all times.
•
The electric power cables should be fastened
properly to the pipes with cable holders or other
suitable equipment. This should prevent loose
hanging and damage to the electric power cables.
Depending on the cable length and weight, a cable
holder should be fitted every two or three meters.
•
The structural components and foundations must be
of sufficient stability to ensure safe and functional
operation. The operator or supplier is responsible for
the provision.
•
Never let the unit run dry. Therefore, we recommend
installing a level control unit.
•
Use defector plates for the pumped fluid intake that
air cannot introduce into the pumped liquid. this
will lead to that the pump will run smoothly and is
subjected to higher wear and tear.
