4. Transport, Handling, Storage

4.1 Transport, Handling

 Check the pump / pump unit immediately upon

delivery / receipt of despatch for damage or
missing parts.

 The pump / pump unit must be transported

carefully and by competent personnel. Avoid
serious impacts.

 Keep the pump / pump unit in the same position in

which it was supplied from the factory. Take note
of the instructions on the packaging.

 The suction and discharge side of the pump must

be closed with plugs during transport and storage.

Dispose of all packing materials in accordance
with local regulations.

 Lifting devices (e.g. fork-lift truck, crane, crane

device, pulleys, sling ropes, etc.) must be
sufficiently strong and must only be used by
authorized persons.

 The pump / pump unit may only be lifted by solid

points such as the casing, flanges or frame.
Picture 2 shows the correct method of carrying by
crane.

Do not stand underneath suspended loads.
Take note of the general regulations on
prevention of accidents.
The pump / pump unit must be secured against
tipping over and slipping until it has been fixed
in its final location.

Sling ropes must not be fixed to ends of shafts
or the ring loops of the motor.

Slipping out of the pump / unit of the transport
lifting device can cause damages to persons
and things.

4.2 Storage / Conservation

Pumps or units, which are stored over a longer period
before start-up (max. 6 months), must be protected
from moisture, vibrations and dirt (e.g. by wrapping in
oil paper or plastic). Pumps must basically be stored in
a place where they are protected from the weather,
e.g. under dry cover. During this time, all suction and
discharge branches and all other intakes and outlets
must be closed with dummy flanges or plugs.
For longer periods of storage conservation
measurements at machined surfaces and packing with
moisture protection can be necessary!


5. Mounting / Installation

5.1 Mounting of Pump / Unit

The pumps must be bolted to a solid base (e.g.
concrete foundation, steel plate, steel bracket, etc.).
This base must withstand all loads occurring during
operation. The place, where the pump is mounted
must be prepared acc. to the dimensions of the
dimensional drawings. The concrete foundations
should have sufficient firmness acc. to DIN 1045 or
equal standard (min. BN 15), to ensure a secure,
functional mounting.
The concrete foundation must have set, before the
unit is erected. Its surface must be horizontal and
even. For the position and size of the pump feet and
the foundation screws refer to the dimensional
drawing.
Concrete expansion bolts, epoxy capsule anchor bolts
or anchor bolts grouted with the foundation (stone
screws), can be used for.

Sufficient space must be provided for
maintenance and repair work, especially for
replacing the drive motor or the complete pump
unit. The motor fan must be able to take in
enough cool air, and the intake grille must
therefore be at least 10 cm away from any wall,
etc.

 When mounting the pump on the foundation it

must be adjusted at the discharge nozzle by
means of a spirit-level (at discharge nozzle). The
permitted deviation is 0,2 mm/m. Levelling shims
must be inserted next to the foundation anchors
and must lie plainly.

 If vibrations are transmitted to the foundation from

adjoining components, it must be guarded through
adequate vibration damping paddings (vibrations
from outside can impair the bearing).

 To prevent vibrations being transmitted to

adjoining components, the foundation should be
laid on a suitable insulating base.
