Installation, Operating and Maintenance Instruction
4.2 Storage / Preservation
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
5. Mounting / Installation
5.1 Mounting the unit / Foundation
Pumps of design MPB and MPV must be firmly bolted
to a solid substructure (e.g. concrete foundation, steel
plate, steel beam, etc.). The substructure must be
capable of withstanding all loads arising during
operation. The size of the substructure and the
location and size of the recesses for the foundation
anchors can be found in the setup plan.
The structure must be designed according to the
dimensions
of
the
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 errected. Ist surface must be horizontal and
even.

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.
For the set of anchor bolts according recesses
must be provided. If that is not the case, concrete
expansion bolts resp. epoxy capsule anchor bolts
can be used.
The pump must be aligned vertically during
placement on the foundation with the help of a
bubble level (at the pressure joints or at the
suction joints). The permitted deviation is 0,5
mm/m. For adjustment levelling shims can be
used. Levelling shims must be inserted next to the

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
measurements at machined surfaces and packing with
moisture protection can be necessary!
Preservation
On storing the pump longer than 3 month (depends on
order; also see adhesive plate on the pump):
A special preservation has been made ex works.The

system before the first normal startup.

Subsequently, tighten the anchor screws evenly.
The alignment must be carried out with the
utmost care and attention, so that the unit will
operate without failure. If you do not pay
attention to this hint you will lose your warranty!
If vibrations are transmitted to the foundation from
adjoining components, it must be guarded through
adequate vibration damping padding (vibrations
from outside can impair the bearing).
To

laid on a suitable insulating base.
The size of these insulating pads will vary,

specialist.

5.2 Connection of Pipings to the Pump
The pump must not be used as fixed point for
the piping. The permitted piping loads must not
be exceeded, refer to chapter 3.5.
5.2.1 Suction and discharge pipe
The pipes must be of a size and design that liquid
can flow freely into the pump and that the pump
functions without problems. Particular attention is
to be paid to ensuring that suction pipes are
airtight and that the NPSH values are observed.
Under suction lift condition laid the suction pipe in
the horizontal section towards the pump so that it
is slightly inclined upwards so that no air traps
occur. Under positive suction head condition
