6EM Thru 18GM - 1100 Vertical Turbine Pumps 13
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.
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.
