20 6EM Thru 18GM - 1100 Vertical Turbine Pumps
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
Loctite PST #567, Permatex No. 2
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.
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.
5. Lower the column and thread it into the
bowl assembly until it solidly buts
together with the bowl, tightening it firmly
with pipe wrenches.
The line shaft and enclosing tube is to
project out beyond the end of the
installed column.
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 column threads. 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
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.
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.
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.
