Probleme Cause Solution
Insufficient
pressure
The inlet pipeline is too
long or with too many
bends pipe diameter is not
selected as required.
Apply the pipe with the stipu-
lated diameter and make the
inlet pipe short.
Motor works
intermittently or the
stator winding is
burned out
The impeller is jammed or
under overload operation
for a long time .
Clear sundries in the pump
chamber; operate the pump
under the rated flow as much
as possible.
Incorrect grounding.
broken cable or the
electric pump is hit by
lightning.
Seek for the reason, and repla-
ce win dins coils.
Leakage of
mechanical seal
The mechanical seal is
worn and torn by impuri-
ties.
Clear or replace the mechan-
cial seal.
Abnormal noise
from pump
Noise from the bearing. Replace with the same type
bearing
Impeller is jammed. Remove foreign materials.
