diametrically opposite pairs until all are
uniformly snug but not fully tightened
yet. Raise the entire unit a few inches
and remove the box clamp. Install
remaining bolts in the mated flanges,
tightening gradually and uniformly as
before. Tighten all bolts at this time.
Place the protective apron over the
top of the column flange and around the
protruding tube. Wrap a clean rag tightly
around the shaft, over the bearing.
Install the remaining standard-
length column, tube, and shaft sections
in the same manner. When each new
shaft section is suspended over the
pump, ready to be installed, clean and
lubricate the thread at the upper end of
the shaft section already in the pump.
Attach a coupling to the lubricated
thread, screwing it on for one-half its
length. A fine wire inserted in the drilled
hole at the center of the coupling can be
used as a gauge to determine when the
coupling is correctly positioned. Be sure
to remove the wire after installing the
coupling.
For pumps having a head shaft
(“second top shaft”) just below the top
shaft, install it with the top column
section; the top shaft will be installed
after the driver. When the column
section has been bolted into place,
replace the box clamp under the newly
made flange joint and allow the unit to
rest on the clamp. Do not lower the top
column section into the sump yet to
facilitate installation of the discharge
head. Remove eyebolts and sling.
If, for any reason, the site is left unattended before the
installation is complete, all openings must be covered to
prevent entry of children, animals, stones, or any other
foreign objects, either by accident or by vandalism. Use
unbreakable covers that cannot be removed without
tools. Violation of this warning could result in severe
property damage or grave personal injury.
