14 6EM Thru 18GM - 1100 Vertical Turbine Pumps
A line shaft coupling should already be in
place on the pump shaft. Thread the line
shaft into the coupling.
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.
C. Hoist the first section of column into
position over the assembled line shaft.
Lower the column onto the bowl
discharge flange. All column joints
should be coated with non-hardening
gasket sealant such as Loctite PST
#567, Permatex No. 2 or equal. Silicon
sealants are also permissible. Install
bolts and nuts and tighten.
IMPORTANT
Measure the shaft projection. It should
conform to the shaft projection
measurement taken and recorded
previously on the bowl assembly.
D. The line shaft is to project out beyond
the end of the installed column. Install
the bearing retainer assembly over the
shaft projection. Seat the retainer OD in
the column flange counterbore.
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.
E. 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
flange. Lower the assembly so the pipe
clamp suspends the assembly on the
foundation.
F. Install the next shaft and column
segment as previously instructed
assuring that its lower flange
counterbore engages the top of the
bearing retainer OD. Coat the column
counterbores with sealant prior to
installation.
Install bolts and nuts and tighten. A slight
gap will remain between the two column
flanges. This condition allows the
bearing retainer to be clamped securely
between the flanges.
G. Continue subsequent shaft and column
assembly until complete. Continue to
measure the shaft projection after
assembly of each shaft/column section.
