22 6EM Thru 18GM - 1100 Vertical Turbine Pumps
6. Lift the column and bowl assembly
slightly. Remove the pipe clamp from
the bowl and lower the assembly into the
well. Reinstall the pipe clamp on the
upper end of the column directly below
the upper flange. Lower the assembly
until the pipe clamp supports the
assembly on the foundation.
IMPORTANT
Measure the shaft projection. It should
conform to the shaft projection
measurement taken and recorded
previously on the bowl assembly.
7. Repeat the above steps until complete.
Continue to measure the shaft projection
after assembly of each shaft/tube/-
column section.
NOTE
Although standard column length is 10
feet, some non-standard lengths of
column, enclosing tube and shaft may be
required to accomplish the specified
overall length of the pump. These non-
standard lengths should be installed at
the top of the column, directly under the
discharge head.
NOTE
The segment of the line shaft which
protrudes through the combination top
tube tension nut/packing box will always
have a replaceable wear sleeve. This
shaft must be installed so that the sleeve
engages the top tube tension nut
bushing.
Assembly procedure for underground
discharge (U.G.D.) units closely
parallels that of standard pumps with
above ground discharge heads. Always
refer to the Layne/Verti-Line submittal
drawings and setting plans to determine
the proper location of discharge elbow
centerline.
8. Install column flange gasket (when used)
to the upper column flange and secure to
the discharge head being sure it is timed
with the pipe tap hole of the discharge
head.
9. Coat both sides of the copper gasket
and the tension nut threads with sealant
prior to installation. Install the bronze top
tube tension nut gasket onto the top tube
tension nut.
10. Install the combination top tube tension
nut/packing box over the projecting line
shaft and slide into position in the
discharge head. Remembering that the
tension nut threads are left handed
thread it into the top enclosing tube. The
threads should engage the tube
smoothly and allow the washer and nut
to seat squarely in the counter bore of
the discharge head. Torque the
combination top tube tension nut/packing
box (refer to Table #3).
11. Install the packing and glands into the
packing box. Install the gland bolts and
nuts. Allow the gland nuts to remain
loose. Packing adjustment will be
performed late with pump operating. If a
mechanical seal is employed, refer to the
Mechanical Seal section of this manual.
