Introduction
This instruction manual is intended to assist those involved
with the installation, operation and maintenance of Eagle
Model A100 pumps. It is recommended that this manual be
thoroughly reviewed prior to installing or performing any work
on the pump or motor.
I-A. Importance of Instructions
The design, material and workmanship incorporated in the
construction of Eagle pumps make them capable of giving
long, trouble–free service. The life and satisfactory service of
any mechanical unit, however, is enhanced and extended by
periodic inspection and careful maintenance. This instruction
manual was prepared to assist operators in understanding the
construction and correct methods of installing, operating, and
maintaining these pumps.
Study thoroughly Sections I, II, III, and carefully follow the
instructions for installation and operation. Sections IV, V, VI,
VII, and VIII are answers to trouble and maintenance questions.
Keep this instruction manual handy for reference.
I-B. Special Warnings
Eagle Pump and Compressor will not be liable for any damages
or delay caused by failure to comply with the provisions of this
instruction manual. This pump is not to be operated at speeds,
working pressures, discharge pressures, or temperatures higher
than nor used with liquids other than originally intended for,
without written permission of Eagle Pump.
Instruction sheets on various components as well as the
Instruction Book for the pump are included in the shipment.
DO NOT DISCARD!
I-D. Preservation and Storage
Eagle’s normal domestic shipping and storage preparation is
suitable for protecting the pump during shipment in covered
trucks. It also provides protection during covered storage at the
jobsite, and for a short period between installation and start-up.
If the pump is to be idle and exposed to the elements for
an extended period, either before or after installation, special
precautions are required. One approach is to provide special
preservatives and wrapping before shipment. However, after
installation the protective wrappings will have been removed.
Therefore, application of preservatives after installation is
considered a good practice.
The driver, coupling, and mechanical seal manufacturers should
be contacted for their recommendations on preservation and
protection procedures.
I-E. Handling Techniques
Care should be used in moving pumps. Pumps should not be
hoisted by eyebolts. These eyebolts are intended for removing
the back pull–out assembly for maintenance and inspection. An
assembled pump should be hoisted using a sling under suction
flange and under rear of bearing frame. Bedplate mounted units
should be hoisted using slings under bedplate below both pump
and driver.
I-C. Receiving Inspection—Shortages
Care should be taken when unloading pumps. If shipment is
not delivered in good order and in accordance with the Bill–of–
Lading, note the damage or shortage on both receipt and freight
bill. MAKE ANY CLAIMS TO THE TRANSPORTATION
COMPANY PROMPTLY.
SECTION II—INSTALLATION
II-A. Location
Pumping unit should be placed as close as practical to the
source of supply. Floor space and headroom allotted to the unit
must be sufficient for inspection and maintenance. Be sure to
allow for crane or hoist service.
II-B. Foundations
1. Grouted—Bedplate mounted units are normally grouted–in
on a concrete foundation, which has been poured on a solid
footing. This allows a permanent, vibration–absorbing base for
the unit. The location and size of foundation bolts are shown
on the outline assembly drawings supplied for the unit. Fig. 1
illustrates a typical foundation bolt installation.
2. Flexibly Mounted—Installation and leveling of the optional
flexibly mounted bedplate should be carried out in accordance
with assembly drawings supplied in the data package for the
unit.

II-C. Leveling and Grouting of
Baseplate Initial Alignment Check
1. Put the unit in place on wedges located at four points as
shown in Fig. 2. Some long installations may require additional
wedges near center of bedplate.
WEDGES
Figure 2
2. Adjust wedges to level unit (approximately), placing unit
between ” and 1” above foundation. Level or plumb suction
and discharge flanges. Then, bring the coupling halves into
reasonable alignment by adjusting the wedges as needed.
3. Make sure that the baseplate is not distorted and that final
accurate coupling alignment can be established within the limits
of movement of motor and by shimming motor if necessary.
II-E. Alignment—Preliminary
Alignment of the pump and driver is of extreme importance
for trouble–free mechanical operation. Alignment should be
obtained by adding or removing shims from under the motor
feet. The pump bearing frame foot should never be adjusted
to obtain alignment. The proper shimming is installed under
the bearing frame foot at the factory on units shipped with
bedplates. Changing the pump casing or bearing frame in the
field will require a reshimming of the frame foot. The proper
number of shims is installed when the pump shaft is level and
parallel to the bedplate surface. Proper shimming is achieved
by loosening frame foot and tightening casing foot. This should
create a gap between the frame foot and bedplate between 0
and .040 inches (1mm). This must be filled with shims and
the frame foot retightened. If this procedure is not followed,
mechanical problems can result. The final alignment is done
after the unit has been run under actual operating conditions.
The following are suggested steps for aligning the unit, prior to
initial startup.
1. Parallel Alignment: The unit is in parallel misalignment
when the shaft axes are parallel, but not concentric. During
initial alignment, vertical parallel alignment may be different,
due to thermal expansion of the unit at actual operating
conditions. The following is a suggested cold setting for motor
driven units:
Pumpage
Temperature
Above Ambient Set Motor Shaft
Ambient .002–.004” low (.05–.10 mm)
100° F. .000–.002” high (.00–.05 mm)
200° F. .004–.006” high (.10–.15 mm)
300° F. .008–.010” high (.20–.25 mm)
400° F. .012–.014” high (.30–.35 mm)
500° F. .016–.018” high (.40–.45 mm)
4. Tighten foundation bolts finger tight. Build dam around
foundation and pour grout. Fill to level of grout hole making
sure that the areas under the pump and motor feet are filled
solid. Allow grout to harden at least 48 hours before further
tightening foundation bolts. Tighten pump hold down bolts.
II-D. Piping Practices
Guidelines for piping are given in the “Hydraulic Institute
Standards” and should be reviewed prior to pump installation.
All piping should be supported independently of, and line up
naturally with, the pump flanges. NEVER DRAW PIPING
INTO PLACE BY USE OF FORCE AT THE FLANGED
CONNECTIONS OF THE PUMP.
Both suction and discharge piping should be as short and direct
as possible to minimize friction losses. Foundation, pump and
driver hold–down bolts should be tightened prior to connecting
suction or discharge piping to the pump.
On units handling corrosives, the piping can be arranged to
allow flushing of the pump prior to opening of the unit for
servicing. After connecting suction and discharge piping to the
pump, rotate pump by hand to be sure that there is no binding.
2. To check the parallel alignment of “spider–insert” couplings,
place a straight edge across both hubs at four points, 90° apart
(see Fig. 3). To check the parallel alignment of flexible spacer
couplings, place a dial indicator on one hub and rotate that
hub 360° while taking readings on the outside diameter of the
other hub. Alignment occurs when indicator deflection does
not exceed .002” T.l.R. (see Fig. 4) of the recommended cold
setting in elevation and not more than .002” T.l.R. side to side.
To check angular alignment of a “spider–insert” coupling, use
calipers at 90° intervals on the circumference on the outer end
of hubs. When caliper measurements are identical, the unit is
in angular alignment. The correct gap between the hub and
insert will be given in the coupling manufacturer’s instructions
supplied for the pump.
To check angular alignment of flexible spacer couplings, place
a dial indicator on one shaft hub and rotate the hub 360°. Take
readings from the face of the other hub. Alignment is achieved
when deflection does not exceed .002” (see Fig. 5).

1. Check List
a. Lubrication—Pump bearings are normally oil lubricated.
(THE BEARINGS ARE NOT LUBRICATED AT THE
FACTORY.) These pumps are supplied with an oiler which
maintains a constant oil level in the bearing frame. Locate
oiler as shown on the outline drawings supplied for the
unit. See Fig. 6 for correct adjustment of oiler.

1. Packing:
If the pumpage is dirty or hot, it is not suitable to lubricate the
packing. An external source must be utilized, unless the bypass
is equipped with proper separator, filter, and/or cooling system.
This must be piped into the lantern ring connection, also (refer
to packing recommendations).
2. Mechanical Seals:
When mechanical seals are supplied, they are installed and
adjusted at the factory. They must not run dry or in abrasives.
Connect recirculation, flush and/or cooling lines as required,
following instructions on the seal print supplied for the unit.
