4.1 Pre-installation
Precautions
WARNING:
•When installing in a potentially explosive environment, ensure that the motor is properly
certified.
• All equipment being installed must be properly grounded to prevent unexpected dis-
charge. Discharge can cause equipment damage, electric shock, and result in serious in-
jury. Test the ground lead to verify it is connected correctly.
NOTICE:
•Electrical connections must be made by certified electricians in compliance with all inter-
national, national, state and local regulations.
• Supervision by an authorized ITT representative is recommended to ensure proper instal-
lation. Improper installation may result in equipment damage or decreased performance.
4.1.1 Pump location guidelines
Guideline Explanation/comment
Keep the pump as close to the liquid source as
practically possible.
This minimizes the friction loss and keeps the suction piping as
short as possible.
Make sure that the space around the pump is
sufficient.
This facilitates ventilation, inspection, maintenance, and service.
If you require lifting equipment such as a hoist or
tackle, make sure that there is enough space
above the pump.
This makes it easier to properly use the lifting equipment and
safely remove and relocate the components to a safe location.
Protect the unit from weather and water damage
due to rain, flooding, and freezing temperatures.
This is applicable if nothing else is specified.
Do not install and operate the equipment in
closed systems unless the system is constructed
with properly-sized safety devices and control
devices.
Acceptable devices:
•Pressure relief valves
• Compression tanks
• Pressure controls
• Temperature controls
• Flow controls
If the system does not include these devices, consult the engineer
or architect in charge before you operate the pump.
Take into consideration the occurrence of un-
wanted noise and vibration.
The best pump location for noise and vibration absorption is on a
concrete floor with subsoil underneath.
4.1.2 Foundation requirements
Requirements
•Provide a flat, substantial concrete foundation in order to prevent strain and distortion when you
tighten the foundation bolts.
4 Installation
16 Model 5500 Installation, Operation, and Maintenance Manual

• Foundation bolts should be 3.175 - 6.350mm | 0.125 - 0.250 in. smaller in diameter than the pump
frame hole size. The hole size is shown on the certified dimension drawing.
4.1.3 Suction and Discharge Pipe
Provision must be made to support suction and discharge piping independently from the pump to prevent
excessive nozzle loads. Short, direct suction and discharge pipelines and a minimum of elbows and fit-
tings result in the least amount of frictional losses and ideal operating conditions. Excessive friction loss-
es in suction piping could cause cavitation. The suction must be kept free of air leaks, particularly in long
lines or on conditions of suction lift. Flow regulating valves should not be located on the suction side of
the pump. It is recommended that a check valve be used in the discharge line to protect the pump from
reverse flow and excessive pressure during shutdown.
4.1.4 V-Belt Drive Installation Checks
Use the following steps and guidelines to make sure that the v-belt drive is properly installed and that the
belts are properly tensioned.
CAUTION:
The unit must not be operated without the proper drive guard in place. Operating the unit with-
out the drive guard in place could result in personal injury to operating personnel.
1. Alignment must be maintained for full power transmission, minimum vibration, and long drive life. A
dial indicator can be used to check runout on the periphery and face of each sheave. A straight
edge can be used to check the alignment of pump and drive sheaves.

2 2 3
1. Straight edge
2. Incorrect
3. Correct
Figure 4: V-belt alignment
2. When installing new belts, shorten center distance between sheaves so that belts can be put on
without the use of force. NEVER "roll" or "pry" the belts into place, as this could damage the belt
cords.
3. Regardless of the belt section used, the belt should never be allowed to bottom in the groove. This
will cause the belts to lose their wedging action and slippage can occur. Sheaves or belts that per-
mit such a condition to occur should be changed.
4. Proper belt tension is the primary reason for long belt life. Improper tension could cause belt fatigue
and/or hot bearings.
The general method for tensioning belts is given below, and should satisfy most drive requirements.
a) Reduce the center distance so that the belts may be placed over the sheaves and in the
grooves without forcing them over the sides of the grooves. Arrange the belts so that both the
top and bottom spans have about the same sag. Apply tension to the belts by increasing the
center distance until the belts are snug.

b) Operate the drive a few minutes to seat the belts in the sheave grooves. Observe the operation
of the drive under its highest load condition (usually starting). A slight bowing of the slack side
of the drive indicates proper tension. If the slack side remains taut during the peak load, the
drive is too tight. Excessive bowing or slippage indicates insufficient tension. If the belts squeal
as the motor comes on or at some subsequent peak load, they are not tight enough to deliver
the torque demanded by the drive motor. The drive should be stopped and the belts tightened.
c) Check the tension on a new drive frequently during the first day by observing the slack side
span. After a few days' operation the belts will seat themselves in the sheave grooves and it
may become necessary to readjust the drive to show a slight bow in the slack side.
Other methods of determining proper belt tension can be obtained from the drive manufacturer.
5. Belt guards protect personnel from danger and the drive from contamination. Inspect periodically to
assure that belts do not rub against guard.
6. Dirt and grease reduce belt life. Belt dressing affects performance only temporarily and is NEVER
recommended. Maintaining a clean drive is better practice.
If any questions arise pertaining to the drive limitations, consult the drive manufacturer.
4.1.5 Pump-to-drive alignment
Precautions
WARNING:
•Misalignment can cause decreased performance, equipment damage, and even cata-
strophic failure of frame-mounted units leading to serious injury. Proper alignment is the
responsibility of the installer and the user of the unit. Check the alignment of all drive
components prior to operating the unit.
• Follow the coupling installation and operation procedures from the coupling manu-
facturer.
• Failure to disconnect and lock out driver power may result in serious physical injury or
death. Always disconnect and lock out power to the driver before performing any installa-
tion or maintenance tasks.
• Electrical connections must be made by certified electricians in compliance with all
international, national, state, and local rules.
• Refer to driver/coupling/gear manufacturer's installation and operation manuals
(IOM) for specific instructions and recommendations.
NOTICE:
Before beginning any alignment procedure, make sure driver power is locked out. Failure to
lock out driver power will result in serious physical injury.
Proper alignment is the responsibility of the installer and the user of the unit. Check the pump-
to-driver alignment before you operate the unit. Failure to do so can result in equipment dam-
age or decreased performance.
