4. MANAGEMENT
4.1 Storage
All the pumps must be stored in a dry covered place,
with possible constant air humidity, free from vibrations
and dust.
They are supplied in their original pack in which they
must remain until the time of installation.
If this is not the case, accurately close the suction and
delivery mouth.
4.2 Transport
Avoid subjecting the products to needless impacts and
collisions. To lift and transport the pump use lifting
devices with the aid of the pallet supplied with it
(if
contemplated).
4.3
Weight
The adhesive plate on the packaging indicates the
total weight of the pump.
5 INSTALLATION
5.1 Pump installation
–
The pump must be installed in a horizontal position
with the suction manifold as short as possible and
with minimum suction height.
–
The pump must be installed in a well ventilated
place, protected from unfavourable weather
conditions, and with an environment temperature not
higher than 65°C (50°C for single-phase versions).
–
The pump may be installed outdoors, but it must be
protected against atmospheric agents with a suitable
cover.
5.2 Pipes
–
Interception valves must be fitted upstream and
downstream from the pump.
–
The pump must not be subject to mechanical
stresses by the pipes.
–
The pipes must be correctly sized, also taking the
suction pressure into account.
–
If the pump is installed in the lowest point of the
system, residue and impurities may build up inside
it.
–
Install the pump so as to avoid air pockets, especially
on the suction side of the pump.
Fig. 1
5.3 Connecting the pipes
5.3.1 Suction pipe
–
If the pump is installed above the level of the liquid,
a foot valve or non return valve must be installed in
the suction manifold below the level of the liquid.
–
Connect the suction pipe to the suction mouth of the
pump. (Fig. 2).
–
Each coupling of the suction manifold must be well
tightened and completely watertight.
–
If a hose is used as the suction pipe, it must be of a
non collapsible type. It is recommended to use a grid
or filter if there is a possibility of solids getting into
the suction pipe and blocking the pump.
