4.1 Preinstallation
Precautions
WARNING:
• When installing in a potentially explosive environment, make sure that the motor is
properly certified.
• You must ground (earth) all electrical equipment. This applies to the pump
equipment, the driver, and any monitoring equipment. Test the ground (earth) lead to
verify that it is connected correctly.
• Motors without built-in protection must be provided with contactors and thermal
overload protection for single-phase motors, or starters with heaters for three-phase
motors. (See the nameplate on the drive unit to select properly-sized overloads.)
NOTICE:
Supervision by an authorized Xylem representative is recommended to ensure proper
installation. Failure to do so may result in equipment damage or decreased performance.
Evaluate the installation in order to determine that the Net Positive Suction Head Available
(NPSHA) meets or exceeds the Net Positive Suction Head Required (NPSHR), as stated by
the pump performance curve.
4.1.1 Pump mounting guidelines
Series e–80SC pumps can only be mounted with the motor shaft vertical (motor shaft
down).
The optional Integrated Technologic with Sensorless Control (ITSC) or Integrated
Technologic (IT) can be oriented to different positions relative to the pump nozzles. This
can be easily changed during pump installation by removing the motor mounting
capscrews, raising the motor assembly slightly, 0.015 to 0.030” (if needed), and rotating
the motor assembly around the pump centerline. Raising the motor assembly more than
0.030” could damage the mechanical seal. Replace the motor capscrews when the
preferred position is determined.
CAUTION:
The pump and motor assembly must be properly supported during this procedure to
prevent the pump unit or motor assembly from falling. Failure to properly support the
pump and motor assembly could result in personal injury and or property damage.
4.1.2 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.

Guideline
Explanation/comment
Keep the pump as close to the liquid source as practically
possible.
If the pump is not on a closed system, locate the pump so
that the fewest number of bends or elbows in the suction
pipe are needed.
This minimizes the friction loss and keeps the suction
piping as short as possible.
Series e-80SC INSTRUCTION MANUAL
4 Installation
Guideline
Explanation/comment
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.
For pumps with the optional ITSC/IT installed, be careful not
to damage the ITSC/IT during lifting. Do not wrap the sling
around the ITSC/IT.
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, This is applicable if nothing else is specified.
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.
Acceptable devices:
• Pressure relief valves
• Expansion 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 unwanted noise
and vibration.
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.
Consider a consultation with a noise specialist.
When possible, locate the pump below the fluid level.
This facilitates priming, ensures a steady flow of
liquid, and provides a positive suction head on the
pump.
4.1.3 Piping checklist
WARNING:
• The heating of water and other fluids causes volumetric expansion. The associated
forces can cause the failure of system components and the release of hightemperature fluids. In order to prevent this, install properly sized and located
compression tanks and pressure-relief valves. Failure to follow these instructions can
result in serious personal injury or death, or property damage.
• Avoid serious personal injury and property damage. Make sure that the flange bolts
are adequately torqued.
NOTICE:
Never force piping to make a connection with a pump.

The code for Pressure Piping (A.S.A.B. 31.1) lists
many types of supports available for various
applications.
Check that fittings for absorbing expansion are
installed in the system when considerable
temperature changes are expected.
This helps to avoid strain on the pump.
Check that you have a foot valve of equal or greater
area than the pump suction piping when you use in
an open system with a suction lift.
Prevent clogging by using a strainer at the
suction inlet next to the foot valve. Make sure
that the strainer has an area three times that of

Operation, and Shutdown
5.1 Preparation for startup
WARNING:
• Failure to follow these precautions before you start the unit 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.
• If the pump, motor, or piping operate at extremely high or low temperatures, then
guarding or insulation is required. Failure to follow these instructions can result in
serious personal injury or death, and property damage.
• 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.
NOTICE:
• Verify the driver settings before you start any 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 clear 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.
5.1.1 Check the rotation
WARNING:
• Operating the pump in reverse rotation can result in the contact of metal parts, heat
generation, and breach of containment.
• 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.
1. Unlock power to the driver.
2. Make sure that everyone is clear, and then jog the driver long enough to determine
that the direction of rotation corresponds to the arrow on the pump.
3. Lock out power to the driver.

5.2 Prime the pump
CAUTION:
Do not run the pump dry.
Make sure that the pump body is full of liquid before startup. If the system does not
automatically fill the pump body with liquid, then you must manually prime the pump.
1. Loosen the vent plugs on the pump body.
2. While venting the air from the pump body, rotate the pump shaft a few times by hand.
3. After all air has been purged from the pump, close the vent plugs.
5.3 Start the pump
CAUTION:
• Observe the pump for vibration levels, bearing temperature, and excessive noise. If
normal levels are exceeded, shut down the pump and resolve the issue.
If your Series e–80SC pump is equipped with the optional ITSC or IT drive, refer to the
ITSC/IT instruction manual for proper setup and running requirements.
Before you start the pump, you must perform these tasks:
• Open the suction valve.
• Open any recirculation or cooling lines.

Series e-80SC INSTRUCTION MANUAL
5 Commissioning, Startup, Operation, and Shutdown
5.4 Pump operation precautions
General considerations
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.
NOTICE:
• 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:
Do not expose an idle pump to freezing conditions. Drain all liquid that is inside the pump
and the flush lines. Failure to do so can cause liquid to freeze and damage the pump.
5.5 Shut down the pump
1. Slowly close the discharge valve.
2. Shut down and lock the driver to prevent accidental rotation.
5.6 Vibration
After startup, vibration can be measured on the pump bracket at the base of the
horizontal (H), vertical (V), and axial (A) directions. The maximum expected value is 0.15
in/sec (3.8 mm/sec) RMS (ANSI/HI 9.6.4) when operating in the Preferred Operating
Range (POR) flows from 70% to 120% of the best efficiency point (BEP) (ANSI/HI 9.6.3).
Operation outside the POR, but within the Allowable Operating Range (AOR) from
minimum flow to 85% of the end of the curve increases the vibration value by 30%. If the
vibration recorded exceeds these values, shut down the pump, diagnose and fix the
problem, re-start, and re-check the vibration.

6.1 Lubrication
The pump motor has been lubricated at the factory. Keep the motor properly lubricated in
accordance with the motor manufacturer's instructions.
6.2 Disassembly
6.2.1 Disassembly precautions
This manual clearly identifies accepted methods for disassembling units. These methods
must be adhered to.
WARNING:
• Make sure that the pump is isolated from the system and that pressure is relieved
before you disassemble the pump, remove plugs, open vent or drain valves, or
disconnect the piping.
• 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.
• Crush hazard. The unit and the components can be heavy. Use proper lifting methods
and wear steel-toed shoes at all times.
NOTICE:
Make sure that all replacement parts are available before you disassemble the pump for
overhaul.
6.2.2 Drain the pump
CAUTION:
• Allow all system and pump components to cool before you handle them to prevent
physical injury.
1. Close the isolation valves on the suction and discharge sides of the pump.
You must drain the system if no valves are installed.
2. Open the drain valve.
Do not proceed until liquid stops coming out of the drain valve. If liquid continues to
flow from the drain valve, the isolation valves are not sealing properly and you must
repair them before you proceed.
3. Leave the drain valve open and remove the drain plug located on the bottom of the
pump housing.
Do not reinstall the plug or close the drain valve until the reassembly is complete.
4. Drain the liquid from the piping and flush the pump if it is necessary.
5. Disconnect all auxiliary piping and tubing.
6.2.3 Impeller trimming guidelines
Machining
When it is necessary to reduce the pump flow rate and generated head by trimming the
impeller diameter, the following guidelines apply for stainless steel impellers:
18
Series e-80SC INSTRUCTION MANUAL

6.3.3 Assemble the coupler
For all pump sizes, except 10x10X13.5, 12x12x13 and 14x14x14:
1. Ensure the coupler halves are clean and burr free. Use sand paper to remove any
burrs and sharp edges with the keyways, set screw collar groove and tapered washer
groove. The collar, tapered washer and keys must slide within their grooves without
interference.
2. If removed, install the set screw collar ring on the motor shaft according to the
instructions above.
3. Upon disassembly, the impeller and pump shaft weight cause the rotor to move
downward and rest at the bottom of the volute. During reassembly, pump shaft and
impeller will be pulled back up into position by the tapered washer acting against the
tapered groove in the coupler (patent pending).
4. After the seal is pre-assembled onto the pump according the section above, assemble
the tapered washer with cap screw and lock washer on the end of the pump shaft. An
allen wrench can be placed in the hole on the side of the shaft to prevent it from
rotating while tightening the cap screw.
5. Install the keys in the motor and pump shafts and turn the motor shaft until the keys
line up.
6. Place the coupler half with the key ways on the motor setscrew collar and on both
keys. Check that the tapered washer installed on the end of the pump shaft is starting
to engage the taper groove in the coupler half.
7. Place the other half of the coupler around the shaft.

8. Insert the coupler cap screws and place a lock washer and nut on each screw. The bolt
heads at each level on opposite sides of the coupling should face in different
directions for balance as shown in the Figure below.
9. Tighten all of the bolts evenly to avoid mis-alignment. The shaft and impeller are
pulled up in to position as the bolts are tightened. Then rotate the shaft by hand and
make sure the gap on both sides of the coupler is approximately equal. Make sure the
gap from the top to the bottom of the coupler is even. If the gap is not equal, loosen
the bolts and repeat the tightening step.
10. Slowly rotate the shaft by hand and check to see if any rubs occur.
1. If no rubs occur, prime and start the pump run for two minutes and determine if
the pump run smooth and vibration free.
2. If problems occur, check the installation and repeat as necessary.
