16 6EM Thru 18GM - 1100 Vertical Turbine Pumps
IMPORTANT
Line shaft threads are left hand. Tighten
shafts and couplings securely with pipe
wrenches.
Assure that no burrs or foreign matter
exists on the coupling or on the shaft
threads. The threaded shafts are to butt
together solidly and squarely in the
center of the coupling. Both shafts are
to be equally engaged in the coupling
threads. Threads should be exposed on
both ends of the coupling.
NOTE
Shafts with replaceable wear sleeves
must be positioned to engage line shaft
bearings. The presence of any foreign
material between the shaft ends will
cause shaft misalignment and will result
in vibration or accelerated bearing wear.
IMPORTANT
Assure that no burrs or foreign matter
exists on the column coupling threads or
on the column threads prior to assembly.
All joints are to be coated with sealant
prior to assembly. The column sections
should butt together solidly and squarely
in the middle of the column coupling.
Secure each joint firmly with appropriate
wrenches. ALL COLUMN THREADS
ARE RIGHT HAND ROTATION.
3. Lower the column and thread it into the
bowl assembly until it solidly and
squarely butts together with the bowl,
tightening with appropriate wrenches.
4. Lift the column/bowl assembly slightly
and remove the pipe clamp from the
bowl. Lower the assembly and reinstall
the pipe clamp below the upper column
threads. Lower the assembly so the pipe
clamp suspends the assembly on the
foundation.
The line shaft is to project out beyond
the end of the installed column.
IMPORTANT
Measure the shaft projection. It should
conform to the shaft projection
measurement taken and recorded
previously on the bowl assembly.
NOTE
Coat the column counterbore with
sealant prior to a retainer installation.
NOTE
Bronze line shaft bearings are to be
lubricated with grease prior to
installation. Rubber line shaft bearings
should NOT be lubricated. Lubrication of
rubber bearings may cause distortion or
swelling.
5. Slide the bearing retainer with bearing
over the shaft projection and lower into
the column coupling. Install the shaft
coupling and next section of
shaft/column assembly as previously
outlined.
6. Continue subsequent shaft and column
assembly until complete. Continue to
measure the shaft projection after
assembly of each shaft/column section.
NOTE
Standard shaft and column lengths are
10 feet. Non-standard lengths of shafts
and column may be used to accomplish
the required overall pump length. Non-
standard shaft/column sections will
always be assembled at the top of the
pump, directly under the discharge head.
The shaft segment which protrudes
through the packing box will always have
a replaceable wear sleeve unless
otherwise specified and submitted.
