Precautions
WARNING:
• When installing in a potentially explosive environment, make sure that the motor is properly certified.
• You must earth (ground) all electrical equipment. This applies to the pump equipment, the driver, and
any monitoring equipment. Test the earth (ground) lead to verify that it is connected correctly.
NOTICE: Supervision by an authorized ITT representative is recommended to ensure proper installation.
Failure to do so may result in equipment damage or decreased performance.
Pump location guidelines
WARNING:
Assembled units and their components are heavy. Failure to properly lift and support this equipment can
result in serious physical injury and/or equipment damage. Lift equipment only at the specifically identified
lifting points. Lifting devices such as eyebolts, slings, and spreaders must be rated, selected, and used for
the entire load being lifted.
GuidelineExplanation/comment
Keep the pump as close to the liquid source as
practically possible.
Make sure that the space around the pump is
sufficient.
If you require lifting equipment such as a hoist or
tackle, make sure that there is enough space above
the pump.
Protect the unit from weather and water damage
due to rain, flooding, and freezing temperatures.
Do not install and operate the equipment in
closed systems unless the system is constructed
with properly-sized safety devices and control
devices.
Take into consideration the occurrence of
unwanted noise and vibration.
This minimizes the friction loss and keeps the suction
piping as short as possible.
This facilitates ventilation, inspection, maintenance,
and service.
This makes it easier to properly use the lifting
equipment and safely remove and relocate the
components to a safe location.
This is applicable if nothing else is specified.
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.
The best pump location for noise and vibration
absorption is on a concrete floor with subsoil
underneath.
If the pump location is overhead, undertake
special precautions to reduce possible noise
transmission.

Installation
Prepare the foundation for mounting
1.Chip the top of the foundation to a minimum of 1.0 in. (25.0 mm) in order to remove porous or lowstrength concrete.
If you use a pneumatic hammer, make sure that it does not contaminate the surface with oil or other
moisture.
NOTICE: Do not chip the foundation using heavy tools such as jackhammers. This can damage the
structural integrity of the foundation.
2.Remove water or debris from the foundation bolt holes or sleeves.
3.If the baseplate uses sleeve-type bolts, then fill the sleeves with a non-binding, moldable material. Seal
the sleeves in order to prevent the grout from entering.
4.Coat the exposed portion of the anchor bolts with a non-bonding compound such as paste wax in
order to prevent the grout from adhering to the anchor bolts.
Do not use oils or liquid wax.
5.If recommended by the grout manufacturer, coat the foundation surface with a compatible primer.
Install the baseplate using shims or wedges
Required tools:
• Two sets of shims or wedges for each foundation bolt
• Two machinist's levels
• Baseplate-leveling worksheet
This procedure is applicable to cast iron and fabricated steel baseplates.
1.If you use sleeve-type bolts, fill the bolt sleeves with packing material or rags to prevent grout from
entering the bolt holes.
2.Put the sets of wedges or shims on each side of each foundation bolt.
The sets of wedges should have a height of between 0.75 in. (19 mm) and 1.50 in. (38 mm).

Piping checklists
General piping checklist
Precautions
CAUTION:
• Never draw piping into place by using force at the flanged connections of the pump. This can impose
dangerous strains on the unit and cause misalignment between the pump and driver. Pipe strain
adversely affects the operation of the pump, which results in physical injury and damage to the
equipment.
• Vary the capacity with the regulating valve in the discharge line. Never throttle the flow from the
suction side. This action can result in decreased performance, unexpected heat generation, and
equipment damage.
NOTICE:
Flange loads from the piping system, including those from the thermal expansion of the piping, must not
exceed the limits of the pump. Casing deformation can result in contact with rotating parts, which can
result in excess heat generation, sparks, and premature failure.

Designing suction and discharge piping
The suction and discharge piping must be designed so that a minimum of forces affect the pump. Do not
exceed the force and torque values as shown in the following table. The values are valid for when the
pump is operating or when it is idle.
About the data in the table
The data in the following table has the following characteristics:
• The data complies with the Europump Recommendation for pumps according to ISO 5199.
• The data is only valid for static piping loads.
• The values are valid for pump units with standard IC base frames (ungrouted).
• All of the values refer to standard materials EN-GJS400-18LT and 1.4408.
Permitted nozzle loads and torques at the pump nozzles
These nozzle loads and torques follow the Europump recommendations for this pump according to ISO

• The data for forces and torques are only valid for static piping loads.
• The values in these tables are valid for pump units with standard IC-base frames (not grouted).
• All values for forces and torques refer to standard materials EN-GJS400-18LT and 1.4408.
Vary the capacity with the regulating valve in the discharge line. Never throttle the flow from the suction
side. This action can result in decreased performance, unexpected heat generation, and equipment damage.
Net positive suction head available (NPSHA) must always exceed NPSH required (NPSHR) as shown on
the published performance curve of the pump.

CheckExplanation/commentChecked
Check that an isolation valve is installed in the
suction piping at a distance of at least two times
the pipe diameter from the suction inlet.
Make sure that the suction piping is free from

Check that the piping is level or slopes
downward from the liquid source.
Make sure that no part of the suction piping
extends below the suction flange of the pump.
Make sure that the suction piping is adequately
submerged below the surface of the liquid
source.
This helps to prevent the occurrence of air
and cavitation in the pump inlet.
—
Use a foot valve with a diameter that is at least
equivalent to the diameter of the suction
piping.
This permits you to close the line during
pump inspection and maintenance.
Do not use the isolation valve to throttle the
pump. Throttling can cause these problems:
• Loss of priming
• Excessive temperatures
• Damage to the pump
• Voiding the warranty

Bypass-piping considerations
When to use a bypass line
Provide a bypass line for systems that require operation at reduced flows for prolonged periods. Connect a
bypass line from the discharge side (before any valves) to the source of suction.
When to install a minimum-flow orifice
When a minimum-flow orifice is unavailable
You can size and install a minimum-flow orifice in a bypass line in order to prevent bypassing excessive
flows. Consult your ITT representative for assistance in sizing a minimum-flow orifice.
Consider an automatic recirculation control valve or solenoid-operated valve if a constant bypass
(minimum-flow orifice) is not possible.

Precautions
WARNING:
• Cooling systems such as those for bearing lubrication and mechanical-seal systems must be operating
properly to prevent excess heat generation, sparks, and premature failure.
• Sealing systems that are not self-purging or self-venting, such as plan 23, require manual venting prior
to operation. Failure to do so will result in excess heat generation and seal failure.
NOTICE:
The mechanical seal must have an appropriate seal-flush system. Otherwise, excess heat generation and
seal failure can occur.
When to install
You may need to install auxiliary piping for bearing cooling, seal-chamber cover cooling, mechanical seal
flush, or other special features supplied with the pump. Consult the pump data sheet for specific auxiliary
piping recommendations.
Checklist
CheckExplanation/
Check that the minimum flow for each component is 1 gpm (4 lpm).
If the bearing and seal chamber cover cooling are provided, then the

Shutdown
Preparation for startup
WARNING:
• Failure to follow these precautions before you start the pump will lead to serious personal injury and
equipment failure.
• Do not operate the pump below the minimum rated flows or with the suction or discharge valves
closed. These conditions can create an explosive hazard due to vaporization of pumped fluid and can
quickly lead to pump failure and physical injury.
• Never operate the pump without the coupling guard correctly installed.
• Always disconnect and lock out power to the driver before you perform any installation or
maintenance tasks. Failure to disconnect and lock out driver power will result in serious physical
injury.
• Operating the pump in reverse rotation can result in the contact of metal parts, heat generation, and
breach of containment.
Precautions
NOTICE:
• Verify the driver settings before you start the pump.
• Make sure that the warm-up rate does not exceed 2.5°F (1.4°C) per minute.
You must follow these precautions before you start the pump:
• Flush and clean the system thoroughly to remove dirt or debris in the pipe system in order to prevent
premature failure at initial startup.
• Bring variable-speed drivers to the rated speed as quickly as possible.
• Run a new or rebuilt pump at a speed that provides enough flow to flush and cool the close-running
surfaces of the stuffing-box bushing.
• If temperatures of the pumped fluid will exceed 200°F (93°C), then warm up the pump prior to
operation. Circulate a small amount of fluid through the pump until the casing temperature is within
100°F (38°C) of the fluid temperature.
At initial startup, do not adjust the variable-speed drivers or check for speed governor or over-speed trip
settings while the variable-speed driver is coupled to the pump. If the settings have not been verified, then
uncouple the unit and refer to instructions supplied by the driver manufacturer.
Remove the coupling guard
1.Identify the parts of the coupling guard.
IMPORTANT: For pumps with CE conformance, the coupling guard fasteners have devices that
keep them from completely detaching from the guard or the pump. Do not remove these devices or
separate the fasteners from the guard or the pump.

Mechanical seal options
Pumps are usually shipped with mechanical seals installed. If they are not, then refer to the mechanical seal
manufacturer's installation instructions.
These are the mechanical seal options for this pump:
• Cartridge mechanical seal
• Conventional inside component mechanical seal
• Conventional outside component mechanical seal
Connection of sealing liquid for mechanical seals
Seal lubrication is required
Seal faces must have liquid film between them for proper lubrication. Locate the taps using the illustrations
shipped with the seal.
Seal flushing methods
You can use these methods in order to flush or cool the seal:
MethodDescription
Product flushRun the piping so that the pump pushes the pumped fluid from the casing and
injects it into the seal gland. If necessary, an external heat exchanger cools the
pumped fluid before it enters the seal gland.
External flushRun the piping so that the pump injects a clean, cool, compatible liquid directly
into the seal gland. The pressure of the flushing liquid must be 5 to 15 psi (0.35 to
1.01 kg/cm2) greater than the seal chamber pressure. The injection rate must be 0.5
to 2 gpm (2 to 8 lpm).
OtherYou can use other methods that employ multiple gland or seal chamber
connections. Refer to the mechanical seal reference drawing and piping diagrams.
Packed stuffing box option
WARNING:
Packed stuffing boxes are not allowed in an ATEX-classified environment.
The factory does not install the packing, lantern ring, or split gland.
These parts are included with the pump in the box of fittings. Before you start the pump, you must install
the packing, lantern ring, and split gland according to the Packed stuffing box maintenance section in the
Maintenance chapter.
Connection of sealing liquid for a packed stuffing box
WARNING:
Packed stuffing boxes are not allowed in an ATEX-classified environment.
NOTICE:
Make sure to lubricate the packing. Failure to do so may result in shortening the life of the packing and the
pump.
You must use an external sealing liquid under these conditions:
• The pumped fluid includes abrasive particles.
• The stuffing-box pressure is below atmospheric pressure when the pump is running with a suction lift
or when the suction source is in a vacuum. Under these conditions, packing is not cooled and
lubricated and air is drawn into pump.

Pump operation precautions
General considerations
Commissioning, Startup, Operation, and Shutdown
CAUTION:
• Vary the capacity with the regulating valve in the discharge line. Never throttle the flow from the
suction side since this can result in decreased performance, unexpected heat generation, and
equipment damage.
• Do not overload the driver. Driver overload can result in unexpected heat generation and equipment
damage. The driver can overload in these circumstances:
• The specific gravity of the pumped fluid is greater than expected.
• The pumped fluid exceeds the rated flow rate.
• Make sure to operate the pump at or near the rated conditions. Failure to do so can result in pump
damage from cavitation or recirculation.
Operation at reduced capacity
WARNING:
Never operate any pumping system with a blocked suction and discharge. Operation, even for a brief
period under these conditions, can cause confined pumped fluid to overheat, which results in a violent
explosion. You must take all necessary measures to avoid this condition.
CAUTION:
• Avoid excessive vibration levels. Excessive vibration levels can damage the bearings, stuffing box or
seal chamber, and the mechanical seal, which can result in decreased performance.
• Avoid increased radial load. Failure to do so can cause stress on the shaft and bearings.
• Avoid heat build-up. Failure to do so can cause rotating parts to score or seize.
• Avoid cavitation. Failure to do so can cause damage to the internal surfaces of the pump.
Operation under freezing conditions
NOTICE:
Model IC, ICI, ICH, ICIH Installation, Operation, and Maintenance Manual49
Do not expose an idle pump to freezing conditions. Drain all liquid that is inside the pump and the cooling
coils. Failure to do so can cause liquid to freeze and damage the pump.

decontamination procedures in order to eliminate the possible exposure to any hazardous or toxic fluids.
Wear the proper personal protective equipment. Potential hazards include, but are not limited to, high
temperature, flammable, acidic, caustic, explosive, and other risks. You must handle and dispose of
pumped fluid in compliance with the applicable environmental regulations.
1.Slowly close the discharge valve.
2.Shut down and lock the driver to prevent accidental rotation.
Make the final alignment of the pump and driver
WARNING:
• Always disconnect and lock out power to the driver before you perform any installation or
maintenance tasks. Failure to disconnect and lock out driver power will result in serious physical
injury.
• Follow shaft alignment procedures in order to prevent catastrophic failure of drive components or
unintended contact of rotating parts. Follow the coupling installation and operation procedures from
the coupling manufacturer.

Grease lubrication
Consider this information when you lubricate with grease:
• Pumps are delivered from the manufacturer with lubricated bearings and are ready to be used.
• The bearings are filled with lithium-based grease, which is suitable for a temperature range from -22°F
to 194°F ( -30°C to 90°C) when measured at the surface of the bearing frame.
• Make sure that bearing temperatures, measured at the bearing frame, are no more than 122°F (50°C)
above the ambient temperature and never exceed 194°F (90°C) when checked weekly.
Regrease the grease-lubricated bearings
NOTICE:
Make sure that the grease container, the greasing device, and the fittings are clean. Failure to do this can
result in impurities entering the bearing housing when you regrease the bearings.
1.Wipe dirt from the grease fittings.
2.Fill the grease cavities through the fittings with a recommended grease.
3.Wipe off any excess grease.
4.Recheck the alignment.
The bearing temperature usually increases by 9°F to 18°F (5°C to 10°C) after you regrease due to an
excess supply of grease. Temperatures return to normal in about two to four operating hours as the pump
runs and purges the excess grease from the bearings.
Shaft seal maintenance
Mechanical-seal maintenance
WARNING:
The mechanical seal used in an Ex-classified environment must be properly certified. Prior to startup,
make sure that all areas that could leak pumped fluid to the work environment are closed.
Model IC, ICI, ICH, ICIH Installation, Operation, and Maintenance Manual53
Page 56
Maintenance
CAUTION:
Never operate the pump without liquid supplied to mechanical seal. If you run a mechanical seal dry, even
for a few seconds, this can cause seal damage. Physical injury can occur if a mechanical seal fails.
Reference drawing
The manufacturer supplies a reference drawing with the data package. Keep this drawing for future use
when you perform maintenance and seal adjustments. The seal drawing specifies the required flush fluid
and attachment points.
Before you start the pump
Check the seal and all flush piping.
Mechanical seal life
The life of a mechanical seal depends on the cleanliness of the pumped fluid. Due to the diversity of
operating conditions, it is not possible to give definite indications as to the life of a mechanical seal.
Packed stuffing-box maintenance
WARNING:
• Packed stuffing boxes are not allowed in an ATEX-classified environment.
• Never attempt to replace the packing until the driver is properly locked out and the coupling spacer is
removed.
Accepted leakage rate
Adjustment of gland
Tightening of packing
It is not necessary to shut down or disassemble the pump to inspect the packing operation. During normal
operation the packing should leak approximately 30-100 drops per minute.
Adjust the gland if the leakage rate is greater than or less than the specified rate.
Evenly adjust each of the two gland bolts with a one-quarter (1/4) turn until the desired leakage rate is
obtained. Tighten the bolts to decrease the rate. Loosen the bolts to increase the rate.
NOTICE: Never over-tighten packing to the point where less than one drop per minute is observed.
Over-tightening can cause excessive wear and power consumption during operation.
If you cannot tighten the packing to obtain less than the specified leakage rate, then replace the packing.

Pre-assembly inspections
Guidelines
Before you assemble the pump parts, make sure you follow these guidelines:
• Inspect the pump parts according to the information in these pre-assembly topics before you
reassemble your pump. Replace any part that does not meet the required criteria.
• Make sure that the parts are clean. Clean the pump parts in solvent in order to remove oil, grease, and
dirt.
NOTICE: Protect machined surfaces while you clean the parts. Failure to do so may result in
equipment damage.
Replacement guidelines
Casing check and replacement
Inspect the casing for cracks and excessive wear or pitting. Thoroughly clean gasket surfaces and alignment
fits in order to remove rust and debris.
Repair or replace the casing if you notice any of these conditions:
• Localized wear or grooving that is greater than 1/8 in. (3.2 mm) deep
• Pitting that is greater than 1/8 in. (3.2 mm) deep
• Irregularities in the casing-gasket seat surface

This table shows the criteria for replacing the impeller:
Impeller partsWhen to replace
Impeller vanes
Vane edgesWhen you see cracks, pitting, or corrosion damage
Impeller clearances and reconditioning
When you recondition the impeller, consider this information:
• For pumps installed in potentially explosive atmospheres, you must replace worn parts when the wear
limits have been reached.
• For volute casings (102V) with a wear ring (502.11) and casing covers (161) with a wear ring (502.31),
you can restore the correct clearance in one of two ways:
• Replace the impeller and the wear ring.
• Contact your ITT representative in order to acquire a customized wear ring (bored to fit) in order
to avoid replacement of the impeller.
• When the volute casing (102V) or casing cover (161) without a wear ring must be repaired, you can
install a wear ring in order to renew pump performance. The volute casing and/or the casing cover
must be re-machined. Contact your ITT representative for assistance.
• When grooved deeper than 1/16 in. (1.6 mm),
or
• When worn evenly more than 1/32 in. (0.8 mm)
