24 6EM Thru 18GM - 1100 Vertical Turbine Pumps
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
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.
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 units closely parallels that of
standard pumps with above ground
discharge heads. Always refer to the
Layne/Verti-Line submittal drawings and
setting plans.
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. Thread the top column adapter flange
onto the top column and tighten with
appropriate wrenches. Install column
flange gasket and secure the discharge
head to the column adapter flange.
When attaching the column to the
discharge head, make sure the flange is
timed with the pipe tapped hole in the
discharge head.
9. Install the bronze top tube tension nut
washer onto the top tube tension nut.
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).
12. 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.
Driver Installation
IMPORTANT
Read and understand the driver manu-
facturer's manual before proceeding.
Determine if the driver is to be installed is a
vertical hollow shaft electric motor, a solid
shaft motor or a right angle gear. Refer to
the appropriate instructions.
