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
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
measurements at machined surfaces and packing with
moisture protection can be necessary!
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.
Sufficient
space
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
foundation
anchors
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).

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
product used for this must be removed by rinsing the
system before the first normal startup.
To
prevent
adjoining components, the foundation should be
laid on a suitable insulating base.
The size of these insulating pads will vary,

therefore be determined by an experienced
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
for
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
install the suction pipe work slightly declined
towards the pump. Do not install fittings or elbows
right before the suction nozzle.
When laying the pipes, make sure that the pump
is accessible for maintenance, installation and
disassembly.
Notice "Permitted Forces on Flanges" (chapter
3.5).
If expansion joints are used in the pipes, they
have to be supported in such a way that the pump

is not loaded unduly high because of the pressure
in the pipes.
Before connecting up to pump: remove protective
coverings from suction and discharge branches.
Before starting up, the pipe system, fittings and
equipment must be cleaned to remove weld
spatter, scale etc. Any pollutants are to be
completely removed from pump units that are
directly or indirectly connected to drinking water
systems before being installed and taken into use.
