start difficultly
Insufficient
water flow
Electric pump
suddenly stops
Stator winding
burnt out
EN
Main reasons
1. Power voltage too low.
2. Pump phase lost.
3. Impeller clogged.
5. Big loss of cable voltage.
6. Stator winding burnt.
1. Head too high.
2. Strain and inlet clogged
3. Impeller worn severely.
4. Submersion shallowed
too much and air sucked in.
5. Impeller rotates
counterclockwise
1. Switch disconnected, or
fuse burnt.
2. Impeller clogged.
3. Stator winding burnt out.
1. Electric pump runs too
long with phase lost.
2. Winding turn-to-turn
short circuit or short circuit
between phases due to
mechanical seal leakage.
3. Impeller clogged.
4. Electric pump starts and
stops frequently
5.Electric pump runs in
overload.
Solution
1. Adjust voltage to 0.9-1.1 times of
the rated range.
2. Check the switch, terminal, cable..
4. Adjust clogged position.

1. Used within the range of rated
head.
2. Remove water weed and other
foreign matter.
3. Replace impeller.
4. Adjust the submersible depth till
no less than 0.5m.
5. Swap over any two- phases out of
phase.
1. Check whether the head in use or
power voltage is in compliance with
requirements and adjust accordingly.
2.Remove foreign matter.
3. Rewinding and overhaul;
Remove the troubles, disassemble
the winding and rewind, bake it in
the insulating lacquer or send it to
