3. MANAGEMENT

Supply and storage

All pumps leave the factory only after they have been subjected to a careful series of checks. However, the
material must be inspected immediately after delivery in order to be able to check for any damage caused
during transport.
If the pump is not to be used immediately, it must be stored in a cool and not excessively dry place, tightly
closed in its original packaging.

Transport

The electric pump unit must be handled with care using suitable lifting equipment and slings that comply with
safety regulations.
Do not apply bending stress to the unit.
Never use power or earth cables to move the pump.

Weight

The adhesive plate on the packaging indicates the total weight of the pump.

4. PUMPED LIQUIDS

The machines have been designed and made for pumping water, free from explosive substances and solid
particles or fibres, with a density of 1000 Kg/m³, a kinematic viscosity of 1mm²/s and non chemically
aggressive liquids. The pump is not suitable for pumping flammable or dangerous liquids.

6. COUPLING OF THE PUMP TO THE SUBMERSIBLE MOTOR

For 4" disassembled pumps
The pump is suitable for coupling with a 4" submersible motor in
accordance with NEMA standards.
For correct coupling proceed as follows (Fig.1):
- Remove the cable guard (1) by unscrewing the fixing
screws (2) and unhooking it from the external casing of the
pump (7).
- Make sure that the shaft, joint and coupling surfaces are
clean.
- Position the motor (3) vertically.
- Couple the pump to the motor, making sure to align the
"cable gland" opening of the lower support with the cable
outlet of the motor.
- After coupling, screw the nuts (4) onto the tie rods (5)
securing the pump to the motor, tightening them in
sequence according to the diagonals and with a tightening
torque of 18 N/m ± 1.
- Lay the motor cable (6) along the pump (7) and cover it
with the cable guard (1).
- Attach the cable guard to the casing and secure it with the screws (2).
