Fault: Motor overload
Possible cause
Pump's back pressure is
less than that indicated in
the order.
Higher density of the
pumping liquid than that
indicated in the order.
Too high a speed.
Running on two phases.
Transport fuse not
removed from the shaft
groove.

Solutions
Set operating point exactly.
For constant overload turn the
impeller - (further enquiry
required).
Contact manufacturer.
Reduce speed - (further enquiry
required).
Renew faulty fuse.
Check electrical power
connections.
Remove the transport fuse from
the shaft groove.
Solution
Reduce speed - (further enquiry
required).
Solution
Check pipe connections and
pump fasteners, if necessary
reduce the pipe bracket
spacing.
Fasten pipes using vibration
reducing materials.
Clean relief bore in impeller.
Increase minimum flow rate.
