6. MAXIMUM SURROUNDING TEMPERATURE
MAXIMUM: +40 ºC
7. TEMPERATURE OF PUMPED LIQUID
-10ºC - +95ºC
8. STORAGE
Pumps must be stored in a covered place that is dry and, if possible, with constant humidity, free from vibrations
and dust. They are sold in original packing and must remain in this packing until they are installed, with the intake
and supply mouths covered with the adhesive disk provided. After a long period in storage or should the pump be stored
after a certain time working, preserve the parts manufactured in light alloy with preservatives available at any store, such
as GG-25, GGG-40 cast materials, which have been in contact with the pumped fluid.
9. TRANSPORT
Make sure that apparatuses do not suffer unnecessary knocks or shocks. Use hoists and the original palette to raise
and move the unit, always with suitable ropes in vegetable or synthetic fibre, as long as the pump can be slung
easily. The eyebolt located on the motor must not be used to raise the whole unit.
10. INSTALLATION
The electro-pump must be installed in a well-ventilated place with a surrounding temperature not exceeding 40°C.
Installation will be undertaken as close as possible to sea level and horizontally in order to minimise the uptake
distance and prevent losses in loading.
There should be enough space to be able to remove the pre-filter basket for cleaning and refitting and also to remove the
whole pump motor support and turbine.
Foundations
We must try to preserve the pump from any possible flooding. It is the purchaser's responsibility to prepare the
foundations; if foundations are metal, they must be painted to prevent corrosion, well-levelled and sufficiently rigid to
withstand stress. They must be sized in such a way so as to avoid vibration caused by resonance. If the foundations are
concrete, they must have set properly and be entirely dry before the unit is put in place, and the support surface must be
perfectly flat and horizontal. After placing the pump on the foundations, use a level to make sure it is totally horizontal,
if not, fit supplements between the base and the foundations close to the anchoring bolts.
Fitting the pipes
Stop valves must be fitted to the inlet and outlet of the pump to avoid the need to empty the installation to carry out
maintenance on the pump.
It is best to use an uptake pipe with a wider diameter than that of the inlet of the electro-pump and as regards the drive
pipe, it should also be the same as that of the pump drive pipe or wider. Uneven passage between pipes of different
diameters significantly increases losses in load. Passage from a small diameter pipe to a larger one must be gradual.
Carefully make sure that the joints between pipes are fully sealed. Make sure the joints between the clamps and
counterpieces are properly centred in order to prevent flow resistance in the pipe. To prevent bubbles from forming in the
uptake pipe, create a slight difference in the positive inclination of the uptake pipe to the electro-pump.
If more than one pump is installed, each pump must have its own uptake pipe. Make sure than each pump works for a
single uptake pipe, except for the reserve pump (if there is one), which will only start to work if the main pump breaks
down.
It is very important for the uptake and drive pipes to have independent brackets and be well fixed so that the pump does
not have to take their weight or withstand the vibrations caused by the water flowing through them.
If installing a broader pipe than that used for the pump input and output (highly recommendable), we must do so as
follows:
-10ºC - +140ºC
