ORIGINAL OPERATING INSTRUCTIONS
1. Operating conditions
Standard construction
- For clean or slightly dirty water with maximum
sand content:
150 g/m
3
(50 g/m
3
for
SDX).
- Water temperature up to 25 °C (35 °C for 4”).
- Max starts per hour at regular intervals: 20 for 4”
motors, 15 for 6”-8” motors, 10 for 10” motors.
The electric data marked on the label are referred
to the nominal power of the motor.
2. Installation
Along its entire length the well diameter must be
wide enough to allow for passage of the pump with
clearance all round.
Handle the pump carefully; don’t drop it or let it fall.
The safe movement of the equipment is on the
user responsability and any lifting operation
must be carried out by a suitably trained and
qualified personnel.
When threaded connections are used, delivery
pipes must be tightened to avoid any risk of the
pump falling into the well owing to unscrews.
It is advisable to connect the metal pipes to the
threaded joints with spot welding.
With plastic pipes use proper connections.
The SD, 6SDX-series pumps have two holes in
the delivery casing for anchoring and for raising
the pump.
A safety rope or chain of non-perishable mate-
rial should always be used to secure the pump.
Attach the power supply cables to the delivery pipe
with cable clamps placed at intervals of approx 3 m.
Lower the pump into the well, making sure the feed cables
are not damaged in any way during the operation.
Never use the electric power cable
to suspend the pump.
When the pump is operating, the delivery connection must
be submersed at least 1 m below the deepest dynamic
level of the well; for this purpose, it is advisable to install an
automatic control system which will stop operating of the
pump when the level of the water falls below this limit.
Position the pump at a distance from the bottom of
the well which will be sufficient to avoid accumula-
tion of sand or mud around the motor and to elimi-
nate the risk of overheating.
The following components must be installed in the
delivery pipe:
•
a pressure gauge;
•
a check valve at max. 7 m from the pump outlet
and more lift-type check valves (5),
depending
on the type of installation (at least one every 50 m
in the straight vertical pipe above the pump), to
provide protection against water hammering;
•
a
gate valve
to regulate delivery, head and
absorbed power.
If the submersible pump is to be installed in the
horizontal position, the following instructions
must be followed:
•
install the pump with its axis placed at least 0,5 m
above the bottom of the sump, tank or container;
•
install a supplementary check valve, as the
pump valve does not
ensure a perfect seal in the
horizontal position;
•
the plant must allow for easy evacuation of the
air when starting.
2.1. Motor cooling
If the well (or tank) has a diameter which is consi-
derably greater than the pump width, it is neces-
sary to install a
cooling flow shroud
(a flow
inducer sleeve), that is an external jacket to ensu-
re a sufficient flow and water velocity (v ≥ 0,08 m/s
for 4”, 0,16 m/s for 6” and 0,2 m/s for 8”-10”) to
cool the motor.
3. Assembly of the pumps
The pumps are normally supplied with motor and pump
disconnected (except 4SD already assembled).
Connect the coupling and pump-motor suction
lantern. Clean the surface to be coupled. Put the
suction lantern of the pump in correspondance of
the motor studs. Couple the grooved joint of the
pump to the motor shaft.
Screw in the nuts to the suc-
tion lantern, then fix them cros-
swise starting from the one
opposed to the cable as shown
in the figure below. The torque
