To prevent possible failure, it is
advisable to periodically control the
flow rate and current absorption
•
A fall below 50% in the flow rate, as
compared to the rated value, indicates
that the pump is worn
•
Similarly, an increase of the current
absorption above 5% indicates the
presence of abnormal mechanical
failures in the pump and/or motors

In many cases, it is necessary to
replace the worn parts, like impellers,
O-rings and bearings

If the content of sand in pumped water
is high, it is advisable to inspect the

thousand operating hours

If the pump is left idle in the well for
long intervals of time, it is advisable
to start it and allow it to run for a short
time every 2-3 months
