2) Air inlet from the suction
pipe.
3) Suction height above the
height recommended for
the unit.
1) The power supply does not
comply with the data on the
nameplate.
2) A solid object is blocking
the impellers.
3) The liquid is too thick.
4) The liquid or the
environment are too hot.
1) The tank membrane is
damaged.
2) No compressed air in the

REMEDY
1) Verify that voltage is present and that the plug has been
correctly inserted.

lowered below the foot valve - c) the foot valve is sealed and
not blocked - d) there are no siphons, bends, counter-slopes or
throats along the suction pipes.
3) Check and reduce the suction height or use a device with more
suitable characteristics.
1) Check the voltage on the power supply cable leads
2) Disassemble and clean the electropump.
3) Dilute the pumped fluid.
4) Remove the cause of the problem, wait for the pump to cool
down and restart it.
1) Have the membrane or tank replaced by qualified personnel.
2) Fill the tank with air using the delivery valve and a maximum
pressure of 1.5 bar.
3) Disassemble and clean the valve or replace it when necessary.
