8.4 Starting up
WARNING!
Danger of burn!
Depending on conveyed fluid and the operating
cycles of the pump, surface temperature (pump,
motor) can exceed 68°C.
• Take necessary means to avoid injuries!
CAUTION!
Danger of material damage!
The pump must not operate at zero flow (closed
discharge valve) for more than 10 minutes with
cold water (T°C < 40°C) and more than 5 minutes
beyond 60° C.
• We recommend to ensure a minimum flow of
about 10 % of the pump nominal flow to avoid
any vapour lock at the top of the pump.
• Keep the discharge valve closed.
• Start the pump.
• Open draining plug to drain air. If no water leaks
within 20s, close the plug and stop the pump,
then wait for 20s to allow the settling of the air.
• Start again the pump.
NOTE: If necessary (particularly if the suction
height exceeds 5 m) repeat these operations.
• If water leaks at draining plug (it means the pump
delivers its pressure), slowly open the discharge
valve. The pump has to be primed.
• Check pressure stability at discharge with a
manometer, if instability, perfect air draining.
• In case of failure, do the filling in again and start
the operation again.
• To perfect air draining, close the discharge valve
and the draining plug, then stop the pump 20s,
start the pump again and open the draining plug.
Do it as long as air comes out.
• Open the discharge valve in order to have the
wished working point.
• Check that the current input does not exceed the
value indicated on the motor-converter data
plate.
9. Maintenance
Maintenance and repairs may only be carried
out by qualified experts !
It is recommended to have the pump maintained and
checked by an after-sales service technician.
DANGER!
Danger of death!
There is a danger of electrocution, when working
on electrical equipments.
• Only electricians approved by the local electricity
supplier are allowed to work on electrical equip-
ments.
• Before working on electrical equipment, switch it
off and prevent it from being switched on again!
WARNING!
Risk of burn!
High surface temperatures may be reached.
• Allow the pump to cool off before all works.
• Always wear protective clothing and gloves when
working!
• No special maintenance in operation.
• Keep the pump and the motor-converter per-
fectly clean.
• In case of prolonged stopping, if there is no risk
of frost, it is better not to drain the pump.
• The bearing holding the coupling and the motor
bearings are lubricated for their total lifetime and
do not require any lubrication.
• The mechanical seal does not require any main-
tenance in operation. It must never operate dry.
Replacement frequencies
NOTE: These are only recommendations, the
replacement frequency depends on the operat-
ing conditions of the unit , i.e.:
• Temperature, pressure and type of conveyed
fluid for the mechanical seal.
• Load and ambient temperature for the motor and
the other components.
• Starting frequency: continuous or intermittent
running.
