hazards such as needles, and other sharp
objects. Always wear heavy puncture
resistant gloves.
Before attempting to service this pump:
1. Familiarize yourself with this manual.
2. Disconnect or lock out the power source
to insure the pump will not start.
Confirm power source disconnect with
appropriate electrical test equipment.
3. Close the discharge valve.
After the pump has been installed, make
certain that the pump and all piping
connections are tight and are properly
supported prior to start-up and operation.
WARNING
Certain procedures in disassembly and

potable water. Do not attempt to try to clean
the pump with bare hands.
CAUTION
On deep set open line shaft turbines (where
static water level is 50' or greater) it is
recommended that the line shaft bearings
be pre-lubricated prior to the start of the
pump. The discharge head is provided with
a port to accommodate pre-lubrication
piping. Refer to the factory for specific pre-
lubrication instructions.
Storage of Pumps
CAUTION
If the equipment is not to be immediately installed
and operated, THE FOLLOWING INSTRUCTIONS
SHOULD BE ADHERED TO AS A MINIMUM:
Consider a unit in storage when:
1. It has been delivered to the job site and
is awaiting installation.
2. It has been installed but operation is
delayed pending completion of plant
construction.
3. There are long (30 days or more) periods
between operation cycles.
4. The plant (or facility) is shut down.
NOTE
Improper storage could result in product
failures or restoration not covered by
warranty.
Assembled Pumps:
1. Remove the gland halves, packing and
seal water rings from the stuffing box if
the pump is so equipped. If the pump is
equipped with inside mechanical seal,
remove the pipe plug in the stuffing box
cover, and coat the seal with light oil.
This may be done by using an oil can,
squirting the seal through the tapped
opening while rotating the pump shaft. If
equipped with outside seal, oil and cover
for protection.
2. When pumps with rubber bearings are
stored assembled in horizontal position, it
is necessary to rotate the entire pump
and column assembly 90 degrees once
per month. This practice will help prevent
the weight of the shafts from deforming
the rubber bearings. Pumps with metal
bearings stored in horizontal positions
are to have shafts rotated once per
month to prevent line shafts from

8 19GM, 19GH & 21EH 1100 Vertical Turbine Pumps
____________________________________________________________________________________________
Layne/Verti-Line 08/05
deforming or bowing under their own
weight.
3. Pumps stored fully assembled and
installed are to be rotated once per week
to prevent brinelling of motor thrust
bearings. Packing or mechanical seals
are to be serviced as noted above.
Unassembled Pumps:
1. Store the unassembled components in a
clean, dry well-ventilated place free from
vibrations, moisture, and temperature
variation.
2. Wipe clean all exposed machined
surfaces and coat with a heavy layer of
grease or other equivalent rust
preventative material.
3. Cover the suction and discharge of the
pump with cardboard or wood to prevent
entry of foreign material or varmints. This
also applies to column sections.
4. The bearings, shaft, and couplings
should be stored as components, i.e.,
shaft with couplings installed on lower
ends. The ends should then be wrapped
with heavy plastic or protective material
and secured tightly to prevent entry of
foreign matter and varmints.

SECTION 2
INTRODUCTION
General Description
A vertical line shaft turbine pump consists of
five basic components. These components
are the pump bowl assembly, column pipe,
line shafting, discharge head, and driver.
Refer to the drawing section for general
arrangement drawings.
Bowl Assembly
The 1100 series single stage bowl assembly
is made up of a suction bell, a top
intermediate bowl and impeller, and a
discharge case. Units of two or more
stages include a suction bell, multiple
intermediate bowls and impellers and a
discharge case. Refer to the assembly
drawing found in the drawing section of this
manual for your specific configuration.
Column Pipe
Column pipe for pumps covered in this
manual can be either threaded or flanged.
Threaded column features straight threads
on both column ends and butt solidly
together within the coupling. Standard
nominal column lengths for threaded column
are 5 foot, 10 foot or any special length up
to 10 foot.
Flanged column includes registered fits for
accurate column alignment and are bolted
together. Flanged column pipe is available
in standard lengths of 10 foot or 5 foot; or
can be provided in any special length up to
10 foot.
Line Shafting
The turbine line shaft transmits torque from
the pump driver to the pump bowl assembly
and rotates inside the column pipe. Both
ends of the shaft are precision machined,
and are secured together with couplings.
This shafting is supported by bearings at
specific intervals; the types of bearings
used and how they are lubricated are
described as follows:
A. Open Line Shaft - Product Lubricated
This design is such that the line shaft
and bearings are exposed to and
lubricated by the liquid being pumped.
The line shaft is supported at intervals of
not more than 10' by bearings that run
on shaft sleeves. Support for these
bearings is supplied by bearing
retainers. The outer hub of the retainer
is seated between the two column ends.
Refer to the specific assembly drawings
found in the drawing section of this
manual.
B. Enclosed Line Shaft
In the enclosed line shaft design shafting
is surrounded by tubing. This tubing
protects both the shaft and bearings
from the pumped liquid and provides a
channel for lubricating the shaft
bearings. The bearings have machined
grooves on their I. D. to allow lubrication
to flow from one bearing to the next.
These bearings are also threaded on the
outside diameter and are used to
connect the five foot enclosing tube
sections. Lubrication is normally oil from
a separate source. The enclosing tube
may be supported by spiders unequally
spaced to reduce the risk of vibration.
(See the Technical Data Section.)

____________________________________________________________________________________________
Layne/Verti-Line 08/05
Discharge Heads
Discharge heads perform multiple functions:
direct the pump flow from the pump column
to the discharge piping system, provide a
method for sealing the line shaft, provide a
base from which the pump is suspended,
and provide a mounting surface for the
driver.
Surface discharge heads incorporate both
the discharge elbow and driver pedestal in
one piece. An underground discharge
elbow can also be provided in which case a
separate driver pedestal is provided. The
bottom surface of the discharge head or
pedestal is machined when furnished with a
sole plate.
Drivers
A variety of driver sizes and types can be
supplied based on the specific job
requirements. Drivers may be either vertical
hollow or vertical solid shaft motors or right
angle gears connected to horizontal shaft
drivers.
Normally a vertical hollow shaft driver is
used. In this configuration, the line shaft
passes through the driver, positioned with
an adjusting nut to accommodate impeller
adjustment, and is connected to the top of
the driver by a keyed drive hub or coupling.
Solid shaft drivers require special adjustable
couplings in order to attach to the pump
shaft and to accommodate impeller
adjustment. Refer to your submittal
package for your specific pump driver
configuration.

SECTION 3 INSTALLATION
General
Prior to assembly and/or installation, the
pump and loose parts are to be inspected
for completeness, correctness and
cleanliness. During this inspection, all parts
are to be thoroughly cleaned and any burrs
removed by filing. The pump bowl assembly,
including the line shaft coupling, is normally
shipped completely assembled. Both the
suction and discharge openings should be
inspected for damage and for foreign
materials. Rotate the shaft by hand, and
move in and out to check for end play. Place
all parts in an orderly arrangement for
convenient assembly.
WARNING
Extreme caution is to be exercised when
hoisting components with open lifting lugs.
Precautions should be taken to prevent
hoisting slings from coming out of the lugs.
WARNING
Never attempt to mount the driver on the
discharge head prior to installation of the
pump.
WARNING
Never attempt to hoist the entire pump by
the driver lifting lugs or eyes. These lifting
points are designed only to hoist the weight
of the driver, not other attached
components.
IMPORTANT
All shafting has been pre-straightened to a
tolerance of 0.005" in 10 feet prior to
leaving the factory or assembly plant. Care
in handling must be taken to insure that the
shafting is not bent prior to and during
installation.
Foundation
A foundation must be supplied consisting of
any material that will provide a permanent,
rigid support. This support is to be of
sufficient size and depth to fully carry the
weight of the pump (full of water) and rigid
enough to prevent vibration.
Anchor bolts are to be supplied and set in
place by the installing contractor. Anchor
bolts of appropriate size, length and
configuration are required to adequately
secure the discharge head/pedestal to the
foundation.
When the pump is to be mounted over a pit
on structural steel framing, it should be
located as close to the main structure or
wall as possible. Cross members are to be
used to prevent distortion and vibration of
structural mounting frame.
Well and Pit Inspection
Prior to installation and start-up, the well or
pit must be cleaned of all loose material and
debris. Both the suction and discharge
openings should be inspected for damage
and for foreign materials.

12 19GM, 19GH & 21EH 1100 Vertical Turbine Pumps
____________________________________________________________________________________________
Layne/Verti-Line 08/05
CAUTION
Reduced performance and possible
equipment damage may result from
ingestion of foreign material by the pump.
Bowl Assembly
NOTE
Before proceeding, measure and record the
pump bowl assembly end play. This
information will be needed later.
Shaft projection is defined as the distance
from the discharge bowl mounting surface
(flange seat for flanged column, thread seat
for threaded column) to the end of the pump
shaft. Nominal standard shaft projection is
17-1/2". The projection is measured with the
impellers resting at the bottom of their axial
travel.
Shaft end play is the amount of axial
movement available in the pump bowl
assembly. Measure and record the pump
bowl end play. This can most easily be
accomplished with the bowl assembly in a
horizontal position. Grasp the pump shaft
and move the shaft through its maximum
axial travel. Consult Table #1 in the
Technical Data Section to assure that the
distance measured complies with the
specifications for your pump model.
Discharge cases for open line shaft units
are shipped with two pipe plugs installed.
Plugs must be left in place for discharge
cases used with enclosed line shaft water-
flushed and open line shaft units.
CAUTION
Should you receive a bowl assembly for
enclosed line shaft oil lubricated
construction that has two pipe plugs
installed in the discharge case, THESE
PIPE PLUGS MUST BE REMOVED PRIOR
TO INSTALLATION. Failure to remove the
plugs will cause water to enter the enclosing
tube and leak out at the discharge head.
Bearing failure may result.
Suction Strainer
If a suction strainer is to be used, it is to be
either threaded into the suction case or
clipped onto the suction bell as required.
Hoisting, Leveling, Grouting & Piping
If your pump was shipped completely
assembled, it is now ready to install.
WARNING
The pump is to always be lifted using
adequate crane and sling capacity. All
applicable safe hoisting practices should be
employed.
The pump is to be hoisted by the discharge
head. Pumps thirty feet or more in overall
length should also be supported at the
column midpoint to avoid column/shaft
distortion and possible pump damage. The
pump is to be lowered onto the anchor bolts
and leveled. This can be achieved by
applying a good quality machinist's spirit
level to the machined motor mounting
surface or to the below-grade pump column,
if accessible.
After leveling, the base plate is to be
grouted in place with a good quality non-
shrinking grout. After the grout is fully dry,
the base plate is to be nutted solidly in
place against the grout bed.
Leveling devices are to be removed or
backed off and the pump base plate
tightened solidly against the grout bed. All
pockets and/or holes left by removal of
leveling devices are to be filled with grout.

19GM, 19GH & 21EH 1100 Vertical Turbine Pumps 13
____________________________________________________________________________________________
08/05 Layne/Verti-Line
IMPORTANT
Damaging vibration may result if the base
plate is not solidly in contact with the grout
bed. Even the highest quality non-shrink
grouts contract slightly during drying. All
leveling wedges, nuts or jackscrews are to
be removed or backed off prior to final
torquing of the base plate fasteners. Failure
to do so will result in the pump base plate
resting on the leveling devices rather than
the grout bed.
Piping is to be brought in direct axial
alignment with the pump discharge. Flange
faces are to fit closely and squarely. The
pump discharge is to have no strain
imposed upon it by piping misalignment.
Pump Assembly
If the pump has been shipped dis-
assembled, the following instructions are to
be employed to assemble the unit vertically
in the well or sump.
Determine if the pump to be assembled is
Product Lubricated Open Line Shaft, Oil
Lube Enclosed Line Shaft or Water Flush
Enclosed Line Shaft. Prior to assembly, all
components are to be identified and laid out
in order of assembly. Standard length (5’ or
10') intermediate column, and shaft are
interchangeable and can be assembled in
any order. However, shorter non-standard
column and shaft sections are provided to
accomplish the required overall pump
length, and must be installed at the top of
the pump directly under the discharge head.
The top enclosing tube also has longer
threads to engage the top tube tension nut.
On threaded column, all column couplings
are to be installed on the upper end of the
column prior to lifting. This will provide a
stop for pipe clamps during the hoisting
process.
Product Lubricated Open Lineshaft
Flanged Column
A. Using an appropriate hoisting system, lift
the bowl assembly into position over the
well. Lower the bowl partially into the
well. Attach a pipe clamp (see Figure
#1) to the upper most bowl directly under
the bowl discharge flange. Lower the
assembly, allowing it to be supported on
the foundation via the pipe clamp.
B. Lift the first section of pre-assembled
column & shaft into position over the
suspended bowl assembly (see Figure
#2). Care is to be taken not to damage
the threads on the pump shaft or line
shafts. Clean the threads and lubricate
with appropriate thread lubricant.
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.

14 19GM, 19GH & 21EH 1100 Vertical Turbine Pumps
____________________________________________________________________________________________
Layne/Verti-Line 08/05
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
counterbore 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.
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.
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 plan to determine the proper location
of discharge elbow centerline.
If the packing box of the U.G.D. pump is
lubricated by the pumped media, it will be
necessary to provide an air release valve in
the top column. This will prevent air from
becoming trapped in the column above the
discharge elbow, therefore allowing the
media to lubricate the packing box bushing

and packing. If the pump's total dynamic
head is not sufficient to raise the media to
the altitude of the packing box, an alternate
method of lubrication must be provided (i.e.,
grease lubrication).
H. For ease of installation, remove the
packing box if shipped assembled to the
discharge head.
I. Install column flange gasket (when used)
and secure the discharge head to the
last column flange. When attaching the
column to the discharge head, make
sure the register fit is fully engaging the
head.
J. After attaching the column to the
discharge head remove the column
clamp, and lower the unit to the
foundation and tighten mounting bolts.
Check the shaft to see if it is centered in
the packing box opening in the head. If
the shaft is not centered, it could be an
indication of a bent shaft, column not
seated properly, or the unit is not
properly plumbed. Any or all of these
problems must be corrected before
proceeding with the installation of the
unit.
K Apply lubricant to the packing box
bushing and install the packing box on
the discharge head.
L. Install the packing and glands into the
packing box. Install gland bolts and
nuts. Allow the gland nuts remain loose.
Packing adjustment will be performed
later with the pump operating. If a
mechanical seal is employed, refer to the
Mechanical Seal section of this manual.
Threaded Column
1. Using an appropriate hoisting system, lift
the bowl assembly into position over the
well. Lower the bowl partially into the
well. Attach a pipe clamp (see Figure #1)
to the upper most bowl directly under the
bowl threads. Lower the assembly,
allowing it to be supported on the
foundation via the pipe clamp.
2. Lift the first section of pre-assembled
column & shaft into position over the
suspended bowl assembly (see Figure
#2). Care is to be taken not to damage
the threads on the pump shaft or line
shafts. Clean the threads and lubricate
with appropriate thread lubricant.
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.
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.
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 plan to determine the proper location
of discharge elbow centerline.
If the packing box of the U.G.D. pump is
lubricated by the pumped media, it will be
necessary to provide an air release valve in
the top column. This will prevent air from

media to lubricate the packing box bushing
and packing. If the pump's total dynamic
head is not sufficient to raise the media to
the altitude of the packing box, an alternate
method of lubrication must be provided, i.e.,
grease lubrication.
7. For ease of installation, remove the
packing box if shipped assembled to the
discharge head.
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 register
fit is fully engaging the head and the
flange is timed with the pipe tapped hole
in the discharge head.

Oil Lube Enclosed Line Shaft
Flanged Column
1. Using an appropriate hoisting system, lift
the pre-assembled bowl assembly and
position it above the well. Lower the
bowl assembly partially into the well and
attach a pipe clamp (see Figure #1) to
the upper most bowl directly under the
bowl discharge flange. Lower the
assembly, allowing it to be suspended
on the foundation via the pipe clamp.
2. Before proceeding with assembly, lay
out all line shaft, enclosing tube, column
and connectors. Inspect and identify all
items and arrange them in the order in
which they will be assembled.
Oversized diameter enclosing tube
sections (if used) must be installed at the
bottom of the assembly, directly above
the pump discharge bowl. When
oversized tube sections are used,
special stepped connector bearings are
provided in order to adapt them to the
remaining.
Pre-assemble matching sets of shaft,
enclosing tube and column by sliding
them inside each other and attaching
connectors and couplings. This will
allow each set of column/enclosing
tube/shaft to be hoisted into place and
assembled as demonstrated in Figure
#3.
Non-standard lengths of column,
enclosing tube and line shafting must be
assembled at the top of the pump as
previously outlined.
Using an appropriate hoisting system, lift
the shaft/tube/column assembly and
position it above the suspended bowl.
Slide the lower end of the shaft out of
the enclosing tube about one foot. Refer
to Figure #4 for lifting of this assembly.
3. Lower the shaft/tube/column assembly
into position. A line shaft coupling is to
already be in place on the pump shaft.
Assure that the threaded shafts and
coupling are clean and free of burrs.
Lubricate threads with light oil. Thread
the shafts into the coupling so that both
shafts engage the coupling equally. The
shafts should butt together solidly in the
center of the coupling. Threads should
be exposed on both ends of the
coupling. Assure that no foreign matter
exists between the shaft ends. Such a
condition will cause shaft misalignment
and will result in vibration and
accelerated bearing wear.
IMPORTANT
Line shaft threads and enclosing tube
threads are left hand rotation. Tighten
shafts, enclosing tubes and couplings
securely with pipe wrenches.
4. Assure that all enclosing tube threads
and connector bearing threads are clean
and free of burrs. Coat connector
bearing threads with a sealant such as

non-hardening gasket sealant prior to
assembly. Silicone sealants are also
permissible. This step is very important
in preventing entry of the pressurized
pumped media into the enclosing tube.
Thread the enclosing tube onto the
connector bearing and secure with chain
wrenches.
5. Clean all coating or foreign materials
from the column flange faces prior to
assembly. Lower the shaft/tube/column
assembly into position and coat the
flange faces with sealant. Assure that
the flange faces engage squarely and
that all bolt holes align. Install bolts and
nuts and tighten.
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. Before installing the
discharge head, pre-lubricate the
connector bearings by pouring oil down
the enclosing tube. Approximately one
pint of oil should be added for every 20
ft. of pump length.
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.
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 plan 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 top tube tension nut 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
counterbore of the discharge head.
Torque the top tube tension nut (refer to
Table #2).
Threaded Column
Install column couplings the upper end of
the column prior to lifting. This will provide a
stop for pipe clamps during the hoisting
process.
