Two Shell Pumps:
When all stages in pump end shell section
have been removed, proceed by removing
the series shell ange bolts from the inlet
ange and safely remove using safe lifting
and handling methods. Remove the series
spacer. Continue stage component removal
(previous step).

spacer may be engraved to help distinguish it
from standard stock spacers.

models is welded within the shell and cannot
be removed individually. The discharge ring is
considered part of the shell assembly.
