CHAPTER 4
INSTALLATION
4.1 Installation
For what concerns handling and installation, please refer to
section 2.1.
the pump can be bolted in position through the openings in
its feet or in motor feet, or fastened straight to piping (see
pictures).
Pipes should always be connected so to avoid any kind of
stress to the pumps. Suction pipe should be absolutely
airtight, with a diameter larger or (at most) equal to the pump
suction nozzle diameter.
Fluid velocity inside the piping should never exceed 2 mt./sec
At suction and 3 mt./sec. at delivery.
In suction pipes, absolutely avoid slopes toward the pump as
that could from harmful air bubbles; if necessary, use wider
bends. In case of suction from basins, install a foot valve with
strainer. We recommended the use of gate valves upstream
and downstream the pump. Leave enough space for motor
ventilation.
4.2 Electrical Connections
Electrical connections should be made only by specialized
personnel, strictly following the instructions of pump and
electrical equipment manufacturers.
Remove terminal board cover by unscrewing its screws.
connect electrical lines as shown in the picture aside and
inside the terminal board.
NOTE
The motor is not protect against overload.
Power supply shall be made through:
1. A switch with minimum contact opening 3 mm
2. A magnetothermic overload device set on the nominal current
shown on motor nameplate
3. An overcurrent device to protect the electric equipment
Assembly shall be made by skilled technicians.
