POSSIBLE CAUSE

1) No power.
2) Motor protection tripped.
3) Defective condenser.
4) Shaft blocked.
5) Pressure switch installed
incorrectly or damaged.
1) Empty pump body.
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

fluids or the gate valve in the
suction pipe is closed.
1) The tank membrane is
damaged.
2) No compressed air in the
tank.
3) The foot valve on the suction
pipe is blocked and not
appropriately sealed.
1) The pressure required to stop
the pump pre-set on the pressure

the fluid level has not 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.
4-5) 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
