Ordering spare parts for pumps with modified
operating conditions
If the operating conditions have changed since
pump was purchased, add full particulars of new
operating conditions. This is especially important
when selecting new impellers.
CAUTION Should a change in operating condi-
tions be considered, consult your
nearest Flowserve representative or
factory to determine if such a
change is feasible with the existing
pumping unit.

sibility.

feasible.

tered in the field.
