Malfunction
The pump is not
discharging any liquid,
the motor is not
running.
The motor is running,
but the pump is not
discharging any liquid.
The pump stops after a
short time of operation
because the thermal
motor protection
feature has triggered.
Intermittent or erratic
operation.
The volume of the
liquid being discharged
is too small.
Possible cause
No current.
Thermal motor protection feature has
triggered.
The capacitor is defective.
Blocked running wheel
The pump housing is not filled with
liquid.
Air penetrates into the intake line.
Suction height and/or discharge height
too great.
Clogged suction line.
Pressure line clogged.
The electrical supply does not correspond
to the information given on the type plate.
Pump or intake line are blocked by solids. Remove possible congestion.
Liquid is too viscous.
Temperature of liquid or environment
is too high.
Pump is running dry.
Running wheel obstructed by solids.
Please refer to item 2.
Please refer to item 3.4.
The mains voltage out of the tolerance
range.
Motor or running wheel defective.
Please refer to item 2.1.-2.5.
Worn running wheel.
Elimination
Please verify the presence of voltage
and the correct position of the plug.
Separate the pump from the electrical
mains, allow the system to cool down,
eliminate cause.
Please contact the customer service
department.
Eliminate reason of blockage.
Fill the pump housing with liquid (please
refer to "Putting into operation" section).
Check to make sure that:
a.) the connection points of the intake
line are tight;
b.) the inlet opening of the intake
line including the check valve are
immersed into the liquids being
discharged;
c.) the check valve with the filter is tight
and not jammed;
d.) no siphons (i.e. permanently liquid-
filled loops), kinks, counter-slopes or
narrow spots are present along the
intake lines.
Change the arrangement of the
installation so that the suction height
and/or discharge height will not exceed
the max. value.
Remove cause of clogging.
Remove cause of clogging.
Check the voltage of the supply cable.
Pump may not be suitable for this liquid.
If feasible, the liquid should be thinned.
Make sure that the temperature of
the liquid being pumped and the
environment do not exceed the max.
admissible values.
Eliminate causes of dry-running.
Remove solids.
Please refer to item 2.2.
Please refer to item 3.4.
Please make sure that the mains voltage
matches the data on the type plate.
Please contact the customer service
department.
Please refer to item 2.1.-2.5.
