3.8 Permitted pressures and temperatures
Basically the values, regarding pressures and
temperatures, given in the data sheet and / or the
order confirmation, as well as on the name plate, are
valid. Exceeding or remaining under of these values
are undue. If there are no pressures and / or
temperatures mentioned in data sheet and / or order
confirmation, the following limits are valid for suction
pressure and room temperature:
Suction pressure (System pressure) = Pressure at
pump suction: max. 5 bar
Ambient temperature max. 40°C
On application of pumps local laws and regulations
must be noticed, as well (e.g. DIN 4747 or DIN 4752,
section 4.5).

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
Pumps of Model LR, LMR, LRZ and LMZ can get
installed directly into the piping.
Pumps with support foot must be screwed tight to a
stiff base (e.g. concrete basement, steel plate, steel
girder, a.s.o.). The base must withstand all loads
occurring during operation.
The size of the base resp. the position and the size of
the recess for the anchor bolts refer to the
dimensional drawing.
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.
