Safety precautions
This symbol
together with one of the following
words “Danger” or “Warning” indicates the risk level deriving from
failure to observe the prescribed safety precautions:
DANGER

electric shock
DANGER
Warns that failure to observe the precautions
involves a risk of damage to persons and/or
things.
WARNING
Warns that failure to observe the precautions
involves the risk of damaging the pump
and/or the plant.
1. GENERAL INFORMATION
Please observe the following instructions to achieve the best
pump performance possible and a trouble free installation.
These are self-priming horizontal multistage centrifugal pumps
having more than one impeller assembled in-line. The same
flow passes through each impeller but the pressure increases
each time, i.e. more impellers, more pressure. Self-suction are
manufactured to include a recirculation system with automatic
valve achieving suction lifts of up to nine meters. By using a
foot valve on the suction pipe the pump will rapidly self-prime
when operated.
These pumps are designed to operate with clean water, free
from particles in suspension and with a maximum temperature
of 35 degrees centigrade.
Correct pump operation is assured providing the ins-
tructions on electrical connection, installation and use
are strictly adhered to.
Failure to adhere to the instructions can result in prema-
ture failure of the pump and voiding of the warranty.
2. INSTALLATION
2.1 - Transportable pump
The pump foot lends it good stability, so that as long as it rests
on flat ground or a flat base is no need for additional securing.
Ensure that the weight of the pipes does not rest on the pump.
NOTE: the handle is designed for carrying the pump with
the motor switched off and the unit disconnected from
the current supply.
2.2 - Suction pipe assembly
The suction pipe, if longer than 7 meters, must be of the
same or greater diameter than the pump inlet and installed in
an upward inclination to prevent trapped air pockets forming.
If the pump is required to perform a suction lift, to avoid unnec-
essary losses of head on the discharge side, the pump should
be installed as close as possible to the water.
The end of the suction pipe must always remain at least 30 cm
below the water level.
2.3 - Discharge pipe assembly
It is recommended to use pipes with a diameter equal or
greater than the pump outlet. This will reduce loss of head
caused by friction in longer pipe runs.
Pipework must be supported and not rest on the pump.
If a foot valve has not been installed it is recommended to fit a
check valve to prevent accidental draining down of the system.
To ensure leaktightness of the discharge inlet, seal only with
Teflon tape.
2.4 - Electrical connection
The electrical installation must have a multi pole isolator
with minimum
≥
3 mm contact openings protected by a
30 ma. residual current detector (earth leakage trip).
Single phase motors have built-in thermal protection.
On three phase motors the installation of a thermal pro-
tection system is the responsibility of the end user.
Follow instructions given on fig.1 for correct electrical
connection.
2.5 - Pre-start checks
Ensure the voltage and frequency of the supply corres-
pond to the values indicated on the electrical data label.
Ensure that the pump shaft is rotating freely.
Fill the pump body with water through the self priming
plug opening. If a foot valve has been installed, also fill
the suction pipe.
Check all joints and connections for leaks
THIS PUMP MUST NEVER BE DRY RUN.
3. STARTING
Ensure all valves in the pipework are open.
Connect power supply. There will be a delay before water
appears at the end of the discharge pipe.
Viewing from the fan ensure that the rotation of the motor is
clockwise. On three phase pumps the motor may rotate anti-
clockwise. If this is happening the flow will be lower than
expected. To rectify this situation the two supply phases need
to be reversed.
Ensure that the absorbed current is the same or lower than the
maximum shown on the electrical data label. Adjust the ther-
mal relay to suit when using three phase models.
If the pump fails to operate refer to the possible faults, causes
and solutions list for assistance.
4. MAINTENANCE
Under normal conditions these pumps require no spe-
cial or planned maintenance.
If the pump is not to be operated for a long period it is
recommended to remove it from the installation, drain
down and store in a dry, well ventilated place.
ATTENTION: In the event of faults or damage occurring
to the pump, repairs should only be carried out by an
authorised service agent.
When the pump is eventually disposed of, please note
that it contains no toxic or polluting material. All main
components are material identified to allow selective
disposal.
