Problem Cause and solution
The pump starts
up but the thermal protector is
triggered after a
short time or the
fuses blow.
The pump starts
but does not deliver any liquid.
The pump’s delivery is reduced.
• The power supply cable is damaged, the motor
short circuits or thermal protector or fuses are
not suited for the motor current. Check and replace the components as necessary.
• The thermo-overload protection (single phase)
or of the protection device (three-phase) trips
due to excessive current input. Check the
pump working conditions.
• A phase in the power supply is missing. Check
the power supply.
• The pump is clogged with solids and the impeller becomes bound. Clean the pump.
• Air is entering the suction piping, check the liquid level, the tightness of the suction pipes and
the operation of the foot valve.
• The pump is not correctly primed. Repeat the
instructions in Prime the pump (page 5).
• Check for restrictions in the piping system.
• Wrong rotation of the impeller (three-phase).
Check the direction of rotation.
• The pump is not correctly primed. Repeat the
instructions in Prime the pump (page 5).
WARNING:
• Maintenance and service must be performed by skilled
and qualified personnel only.
• Observe accident prevention regulations in force.
• Use suitable equipment and protection.
6.1 Service
