SECTION I
INSTALLATION
A. LOCATION OF PUMP
1.
The pump should be located as near to the liquid source
as possible.
2.
Head room should be provided for the use of hoisting
equipment.
3.
The unit should be accessible for inspection during
operation.
4. It is necessary for satisfactory operation that sufficient
net positive suction head (NPSH) be available at the pump
suction flange. (Net positive suction head is the total head
in feet absolute, determined at the suction nozzle and re-
ferred to datum, less the vapor pressure of the liquid in
feet absolute.)
B. FOUNDATION (See Fig. 1)
Concrete foundations built on solid ground are the most
satisfactory. Foundation bolts of the specified size should
be located as shown on the foundation drawing. It is rec-
ommended that each bolt be fitted with a pipe sleeve ap-
proximately three diameters larger than the bolt and with a
washer to support the head of the bolt in the sleeve. After
the concrete is poured, the pipe sleeves remain in place while
the bolts may be shifted for alignment with the holes in
the baseplate.
Fig. 1
Foundation Bolts
C. LEVELING BASEPLATE (See Fig. 2)
I. Locate leveling plates and shims on both sides of each
foundation bolt and in the center at the pump end of the
baseplate. Allow a minimum of one inch between the base-
plate and the foundation for grouting.
2. Level baseplate across driver pads using shims at the
foundation bolts on the driver end.
3. Level baseplate across pump pads using shims at the
foundation bolts on the pump end.
4. Level baseplate lengthwise using shims at the center on
the pump end.
5. Tighten nuts on the foundation bolts evenly but not too
firmly.
Fig.

D.
GROUTING
• Build forms to confine the grout. The forms must be
securely anchored and shored.
2.
Remove water and waste material from foundation bolt
holes and clean off and dampen the foundation slab.
3. Pour grout through holes provided in the baseplate.
A recommended grout mixture in one part iron base aggre-
gate. one part Portland cement and one part coarse, clean
sand by weight. Approximately 13/4 to 2 gallons of clean
water is required for each 100 pounds of mix. Use sufficient
water to make the mix placeable.
4. Remove air pockets by working and rodding the grout
through holes in the baseplate.
5.
After grout is set, tighten nuts on the foundation bolts.
Do not remove leveling plates and shims.
E. INSTALLING DRIVER ON BASEPLATE
I. If a motor with sleeve bearings is to be used, it must be
mounted so that there is at least 1/8 inch clearance between
the thrust collars on the motor shaft and the face of the
bearings. The following procedure is usually recommended
when the pump is connected directly to the motor:
a.
Measure the total lateral movement of the motor
rotor. It should be approximately 1/2 inch.
b.
Pull the rotor all the way forward toward the pump.
c.
Move the rotor 1/8 inch back from the full forward
position.
2. Adjust the position of the driver so that the distance be-
tween the pump and driver shaft agrees with the callout on
the foundation drawing.
3. The various coupling types and their uses are as follows:
a.
Limited axial end float spacer type coupling, between
pump and electric motor with sleeve bearings.
b. Standard spacer type coupling between pump and
steam turbine, between pump and fluid drive, or between
pump and electric motor with ball bearings.
c.
Limited axial end float standard type coupling, be-
tween fluid drive and electric motor.
4. A spacer type coupling next
to the pump
permits the
pump half coupling to be removed or installed without dis-
turbing the position of the pump or driver. The thrust bear-
ing on the pump or fluid drive will prevent thrust collars on
the motor shaft from touching
the motor bearing faces.
This will prevent overheating or damage to the motor
heari ngs.
5.
Check alignment with a straight edge across the coup-
lings. The driver will be 3116 inch low before shimming.
F. ALIGNMENT OF DRIVERS MOUNTED AT FACTORY
It is always necessary to check, and correct if necessary, the
alignment of the pump and driver shafts after the base has
been grouted in at its permanent installation.This alignment
check must .be performed even though the pump and driver
may have been mounted and aligned at the factory prior to
shipment. The principal reasons for checking alignment
after installation are as follows:
a. Distortion of the base may have occurred as a result
of handling during shipment or unloading.
b. It is impractical to level base plates at the installation
site as precisely as they are leveled at the factory when the
drivers are mounted and aligned. Thus, minor distortion of
the baseplate will occur when it is bolted to the foundation,
which in turn will produce some misalignment.
c.
The factory alignment of pumps is made without
piping loads imposed upon the inlet and discharge connec-
tions. When installation is complete an alignment adjustment
is required to compensate for strain in the pump and bed
plate caused by loads transnitted from the user's piping
system.
d.
Factory alignment of pumps is performed at an aver-
age temperature of 75°F (24°C). Operation of pumps at less
than or greater than this temperature causes alignment
change due to thermal affects on pump pedestal position.
Final alignment should be made with pumps at the actual
operating temperature.
G. ALIGNING PUMP AND DRIVER BY USER (See Fig. 3)
I. Clamp a dial indicator on the driver half coupling. The
indicator bracket must be rigid to insure accuracy of the
dial indicator readings.
2.
Set the indicator button on the outside diameter of the
pump coupling hub and align the hubs to within .002 inch
total indicating reading.
3.
Set the indicator button on the face of the hub and
align the faces parallel at all points.
4.
To check alignment, clamp the dial indicator to the
pump half coupling and take readings on the outside dia-
meter and the face of the driver coupling hub.

NOTE: If a
steam turbine is used and is foot mounted,
alignment should be made with the turbine hot. If align-
ment is made with the turbine cold, the turbine should be
set low by the distrance specified by the turbine manufac-
turer. A suggested turbine setting is .008 inch low, or .016
inch total indicator reading.
5. Scribe, drill and tap holes in
the driver pads for the
driver hold down bolts. Install the hold down bolts and draw
up snugly, then re-check alignment.
H. PIPING
I. Both suction and discharge piping should be as short and
direct as possible. There should be a minimum of bends and
fittings and the bends should be made with a long radius,
when possthle.
2. Piping should be adequately supported near the pump to •
prevent strains being transmitted to the pump when tighten-
ing the flange bolts.
3.
Pipes at the suction and discharge nozzles should be as
larger or larger than the openings in the pump.
I. SUCTION PIPING (See Fig.s 5 through 7)
1. Suction lines must be free from pockets or high spots in
which gas or vapors may be entrapped.
2.
In horizontal lines leading to the pump, only eccentric
reducers should be used.

SUCTI ON
3.
The suction line must be free from air leaks and adequate
provisions should be made for the expansion of hot lines.
4. It is recommended that a temporary screen be installed in
the line at or near the suction nozzle to catch scale or other
foreign material.
A
pressure gauge installed on each side of
the screen
may be used for measuring pressure drop across
the screen.
5.
When
a strainer or foot valve is used on the inlet end of
the suction line, the free area through the strainer or valve
should be three to four times the area of the suction pipe.
J. DISCHARGE PIPING
1.
On some installations, a check valve and a gate valve may
be required in the discharge line. The check valve is used to
prevent liquid from running back through the pump in case
of failure of the driver. The gate valve is used in primming,
starting and when shutting down the pump.
2.
When valves are required in the discharge line, they should
be
located as near as possible to the pump.
3.
In boiler
feed
applications, provisions should be made
for recirculating a portion of the liquid to prevent over-
heating of the pump while operating at reduced capacity.
Fig. 8
Piping for Spare
Pumps
in High Temperature Service.
K. PIPING FOR SPARE PUMPS
(See Fig. 8)
The operating and spare pumps in high temperature service
should be piped as shown in Fig. 8. During operating, hot
liquid from the discharge of the operating pump circulates
continuously through the by-pass to the spare pump and
back to the suction of the operating pump.
L AUXILIARY PIPING
When auxiliary piping is to be installed by the customer,
the size and location of all pipe openings wffi be shown on
the foundation drawing.
CAUTION
If unit is equipped with breakdown bushing assemblies and
condensate
is used for sealing, the condensate must be clean
and free
from scale, abrasive or other material that would
either clog the clearance spaces or damage the bore of the
breakdown bushings or the surface of the shaft sleeve. A fil-
ter or a fine mesh screen should be installed in the conden-
sate feed line to the seals to insure clean condensate.

M. STUFFING BOXES
When installing packing, carefully read the instruction sheet
included in the packing carton. The following procedures
are generally recommended for packing installation:
1. Install the first packing ring and tamp it to the bottom
of the box. If required, a suitable lubricant may be applied
to each ring.
2.
Insert a split sleeve or equivalent number of metal rings
and compress the packing ring by tightening the stuffmg
box gland firmly.
3. Back off the gland and
remove
the sleeve or metal rings.
Repeat
steps 1 and 2 above for each ring, making sure to
stagger the joints 90°. If a lantern ring is used, install the
lantern ring as shown on the assembly sectional drawing.
4.
After the box is packed, tighten the gland firmly and
evenly and let the packing stand for 5 to 10 minutes. Then,
loosen the gland nuts and re-tighten finger tight.
5.
If possible, rotate the shaft a few times by hand. If a
lantern ring is used, make sure it is installed so that adequate
lubricating liquid will pass freely to the rings.
6. Refer to Section II — A, Preparation
For
Operation, for
additional stuffmg box requirements.
N. CONNECTING PUMP AND DRIVER
I. After piping is connected, check alignment of pump
and driver as outlined in Paragraph F.
2. When pump is in alignment, tighten driver hold down
bolts.
3.
Check rotation of driver to be sure that it agrees with
pump rotation.
4. Install spacer between pump and driver half couplings.
For couplings which require lubrication, refer to the coup-
ling manufacturer's manual for lubrication instructions.

SECTION II
OPERATION
A. PREPARATION FOR OPERATION
I. Fill
the oil reservoir to the indicated level with lubrica-
ting oil. A high grade turbine oil having a viscosity of 150
SSU at 100°F is recommended.
2.
Check metal tags or plates attached to coolers, filters and
auxiliary equipment and follow instructions specified there-
on.
3.
Circulate water through the cooling system, if used. Inlet
and drain connections on each -
pump are identified with
metal tags.
4.
Admit lubricating liquid to seals or packings that require
lubrication.
5.
Start the pump following instructions outlined in Para-
graph B, below.
6.
Check leakage from the seals or packings. If packing leak-
age is not adequate, a few light taps with a hammer on the
gland will usually upset the packing sufficiently to increase
the leakage to the required amount.
7.
If leakage rate is more than required after the pump has
run for 10 to 15 minutes, take up slightly on the gland nuts.
NOTE: Do not overtighten the gland, as this will increase
the rate of wear and may cause scoring of the shaft Leakage
will usually decrease after a few days of operation.
8.
In high temperature applications, it is advisable to re-
check alignment after the pump has been warmed up.
B. STARTING
1.
If pump is above the level of the liquid to be pumped,
close the discharge valve. If the pump is below the level of
the liquid, open the discharge valve 1% to 2 turns.
2.
Prime the pump. All air and vapor must be removed.
The pump case and suction pipe must be filled with liquid
before the pump is started up.
NOTE: Pumps that are modified to
function as hydraulic
turbines must also be primed and filled with liquid before
starting. If two turbines are used on a single installation,
both turbines must be primed.
3.
If the pump is fitted with a flushing line, open the line
and admit flushing liquid to the seal chamber for 10 to 15
minutes.
4. Start
the driver and bring the pump up to speed rapidly.
5.
As soon as the pump is up to full speed, open the dis-
charge valve slowly. Do not let the pump run with the dis-
charge valve closed.
6. Check pressure gauges on each side of the temporary
screen in the suction line. A pressure drop across the screen
indicates it is becoming clogged with dirt or scale. In this
case, the pump should be shut down and the screen cleaned
or replaced. A clogged screen can cause damage to the pump.
7. The pump should be shut down if it fails to develop its
rated discharge pressure at operating speed, or if bearings
overheat or there is undue vibration or noise.
C. OPERATING AT REDUCED CAPACITY
If the pump is connected to a constant speed driver, capa-
city can be reduced by throttling the discharge. If the pump
is connected to a variable speed driver, reduction of both
the head and the capacity can be accomplished either by
reducing the speed or by throttling the discharge.
When throttling the discharge, a by-pass connection may
be used to by-pass sufficient liquid to prevent overheating
and vaporization of the liquid in the pump.
D. OPERATING ROUTINE
1. Check bearing temperatures
periodically.
If there is over-
heating, check the oil level in the reservoir and the oil tem-
perature. When ambient temperature is normal, the sump
temperature should not exceed 165°F on pumps equipped
with ball bearings. On pumps with Kingsbury or sleeve type
bearings, the temperature at the cooler outlet should not
exceed 140°F.
2.
Check seals or packings for leakage.
3.
Check circulation of the cooling system, if used. Cooling
requirements will vary according to the ambient tempera-
tures encountered.
4. Check suction and discharge pressure gauges. If the dif-
ferential pressure drops critically, shut down the pump at
once.
E. STOPPING
The pump should be shut down rapidly to keep liquid in
the pump and prevent parts from seizing. After stopping the
driver, close the discharge valve and then the inlet valve, in
that order. When pumps are operating in parallel, it is some-
times necessary to close the discharge valve immediately
after stopping the driver to prevent reverse rotation.
