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
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.
