1. CONDITIONS OF USE
- These peripheral pumps have been designed to pump clean
liquids, without particles, non-abrasive, non-explosive and with a
viscosity similar to water.
- They are intended to operate in well-ventilated places protected
from severe weather.
• Single-phase current:
• Temperature of the liquid:
• Maximum ambient temperature:
• Power of motor:
• Capacity:
• Insulation class:
• Motor protection:
• Maximum pumping height (Ha max):
• Maximum number of starts per hour:
2. INST LL TION
- The SPN series of pumps must be installed horizontally and fixed to
the floor.
- Install the pump as close as possible to the liquid to be pumped.
llow plenty of space around the pump for good ventilation of the
motor and to make maintenance easier.
3. PIPING
-
ssemble and connect the piping so that it does not transmit
vibrations to the pump.
- For a pumping height exceeding 5 m, use an inlet hose with an
internal diameter greater than that of the pump intake.
- In any event, the diameter of the piping must never be less than
the diameter of the openings of the pump.
- The intake piping must be perfectly water-tight and laid in a
continuous rise, to avoid air pockets.
- When operating as a suction pump, fit a foot valve with strainer
which must always be immerged.
- Fit an intake filter to prevent any foreign bodies from entering the
pump.
- If pumping out of a tank, a non-return valve must be installed.
- When operating as a force pump, a cut-off valve must be fitted to
the pump intake.
- To increase the pressure of the mains supply, observe local
regulations.
- In the output piping, fit a gate valve to adjust the flow, the height
of elevation and the power absorbed.
measure the pressure.
- When operating as a force pump, if the head of water exceeds 15
metres, mount a non-return valve between the pump and the
gate valve to protect the pump from "water-hammer".
- Check that the inside of the piping is clean before connecting it.
4. ELECTRIC L CONNECTIONS
Connection to the electricity supply must be done by an
experienced electrician, following the regulations in force.
- The electrical circuit must be earthed.
- Check that the mains supply matches the data on the maker's
plate. The electrical wiring must be connected according to the
diagrams in the lid of the terminal box of the motor.
- The electricity must be connected using a cable fitted with a plug
assembly or a multiple contactor with an opening between
contacts of at least 3 mm.
- With a three-phase supply, install a protective device on the motor
suitable for the voltage stated on the maker's plate.

- Single-phase motors are fitted as standard with heat-sensitive
protection, to halt the pump if the permissible winding
temperature is exceeded.
5. COMMISSIONING
- Check that the shaft turns normally without any abnormal friction.
For this purpose, the smallest models have a screwdriver slot on the
fan end of the shaft.
-
slight initial résistance to rotation may be due to the very slight
axial play of the impeller.
impeller will turn freely.
- The pump must never operate without water.
- Do not start the pump until you have completely filled it with liquid
through the filler opening.
- When operating as a force pump, fill the pump by slowly and
completely opening the valve on the intake hose and at the same
time opening the valve on the output hose to evacuate the air.
- For three-phase pumps, check that the direction of rotation
matches the arrow on the body of the pump.
- If not, invert the two phase wires.
- Check that the pump works within the range of values it was
designed for and that the courant absorbed shown on the
maker's plate is not exceeded.
- If not, adjust the gate valve or install a pressostat.
W RNING ! The maximum power absorption of pumps in the
SPN series occurs at minimum flow.
- The pump must not be operated with the valves closed.
6. M INTEN NCE
- Before a period of inactivity and at low temperatures, the pump
must be completely emptied. To empty an SPN series pump,
remove the clamp from the body of the pump or the filler cap on
the top of the body of the pump. Before restarting the pump,
check that the shaft and the impeller are not blocked by
incrustations or other causes.
- If need be, clean with an appropriate chemical and fill the pump
completely with liquid through the filler hole on the top.
TTENTION! lways cut off the electrical current before any
maintenance operation.
- When ordering spare parts, always state the model of the pump,
the code number on the exploded diagram and the name of the
item.
