3. TECHNICAL DATA

1). When the lighter entire pump needs to be enhanced, the water pump can be transported by
manual.
2). When the heavier entire pump needs to be enhanced, the water pump must be lifted at pump
head with a steel tape or other smilar way.
Probleme

Cause
The inlet pipeline is too
long or with too many
bends pipe diameter is not
selected as required.
The impeller is jammed or
under overload operation
for a long time .
Incorrect grounding.
broken cable or the
electric pump is hit by
lightning.
The mechanical seal is
worn and torn by impuri-
ties.
Noise from the bearing.
Impeller is jammed.

Solution
Apply the pipe with the stipu-
lated diameter and make the
inlet pipe short.
Clear sundries in the pump
chamber; operate the pump
under the rated flow as much
as possible.
Seek for the reason, and repla-
ce win dins coils.
Clear or replace the mechan-
cial seal.
Replace with the same type
bearing
Remove foreign materials.
