OPERATING INSTRUCTIONS

1. Operating conditions

Standard construction

- For clean water with a maximum temperature of

35 °C and maximum sand content of 60 g/m

3

.

- For clean liquids: non-explosive and non-flamma-

ble, non-hazardous for health or the environment,
non-aggressive for pump materials, not containing
abrasives, solid or fibrous particles.                            

- Maximum permissible pressure in the pump

casing: 10 bar.

- Maximum starts/hour: 30 at regular intervals.
Sound pressure: 60 dB (A).

The motor is cooled by the pumped water

passing between the motor jacket and the
external jacket.
The pump is suited for installation in confined
space with minimum ventilation, in areas exposed
to the sun and weather, those subject to risk of
temporary flooding or exposure to water jetting.

2. Installation

Never use the electric power cable to
suspend the pump.

The pump must be installed in the vertical position
with the delivery connection facing upwards.
See installation examples, fig. 1. 

Place the pump as close as possible to the
suction source.

Make sure prolonged accidental
leakage of liquid does not cause
damage to persons or property.

Leakage  may  develop as  a  result  of

overpressure, water hammer, erroneous opera-
tions (such as failing to close a plug or valve) or
other functional disorders. Allow for the possibility
of channeling away any leaked fluid or for an
automatic drainage system against flooding. Put
in a safe place any property which may be dama-
ged by the water. 

Provide for the possibility of draining the
pump without having to drain the entire
system.

3. Pipes

Ensure the inside of pipes are clean and
unobstructed before connection.

ATTENTION: The pipes connected to the
pump should be secured to rest clamps so
that they do not transmit stress, strain or
vibrations to the pump

.

Into stable and rigid pipelines the pump can be
supported directly through the pipes (fig. 2).

Tighten the  pipes or union coupling to the ex-
tent sufficient to ensure a tight seal.
Excessive torque may cause damage to the pump.
When the pipe or union coupling is mounted, keep
the pump connection blocked with a second
wrench, making sure the connection is not
deformed by excessive tightening.
The pipe diameters must not be smaller than the
pump connections.
