All impellers are fully trimmable
however certain models must be angled trimmed.
See the below chart for these exceptions.
a) Obtain a machining arbor from a Flowserve
representative.
b) Carefully mount the arbor into a lathe. Take care
to minimize the runout of the machining arbor.
c) Install the impeller for trimming.
