Installation
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.
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.
If the pump location is overhead, undertake special
precautions to reduce possible noise transmission.
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.
Consider a consultation with a noise specialist.

Foundation requirements
Requirements
• The foundation must be able to absorb any type of vibration and form a permanent,
rigid support for the unit.
• The foundation must weigh at least 2-1/2 times the weight of the pump unit.
• Provide a flat, substantial concrete foundation in order to prevent strain and distortion
when you tighten the foundation bolts.
• Sleeve-type and J-type foundation bolts are most commonly used. Both designs allow
movement for the final bolt adjustment.
• Tie the concrete pad in with the finished floor.
• Use foundation bolts and larger pipe sleeves to give room for final bolt location.

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 high-
14 Series e-1510 Installation, Operation, and Maintenance Manual
temperature 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.
• Never force piping to make a connection with a pump.
Check Explanation/comment Checked
Check that a section of straight pipe, with a length that
is five times its diameter, is installed between the
suction side of the pump and the first elbow, or that a

Installation
Check Explanation/comment Checked
Check that the suction and discharge pipes are
supported independently by use of pipe hangers near
the pump .
Check that there is a strong, rigid support for the
suction and discharge lines.
For pumps with flanges, check that the bolt holes in
the pump flanges match the bolt holes in the pipe
flanges.
Check that the suction or discharge lines are not
forced into position.
Check that fittings for absorbing expansion are
installed in the system when considerable
temperature changes are expected.
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.
Check that flexible piping is used on both the suction
and discharge sides of the pump when you use an
isolation base.
Check that a B&G Triple Duty® valve is installed in the
discharge line.
Check that the pipeline has isolation valves around
the pump and has a drain valve in the suction pipe.
Use PTFE tape sealer or a high quality thread sealant
when you install the suction and discharge
connections to a threaded pump housing.
This eliminates pipe strain on the pump .
As a rule, ordinary wire or band hangers are not
adequate to maintain proper alignment.
—
Coupling and bearing wear will result if suction
or discharge lines are forced into position.
This helps to avoid strain on the pump.
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
the suction pipe with a mesh hole diameter of
no less than 0.25 in. (0.64 cm).
—
This valve serves as a check valve that protects
the pump from water hammer, and serves as an
isolation valve for servicing and for throttling.

Pump insulation checklist
Check Checked
Check that the bearing assembly grease fittings are
accessible and visible.
Check that the vent slots on the sides and bottom of the
bearing assembly are uncovered and completely open.

• 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.
• 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.
• 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. Lock out power to the driver.
2. Make sure that the coupling hubs are fastened securely to the shafts.
3. Unlock power to the driver.

Commissioning, Startup, Operation, and Shutdown
4. 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.
5. Lock out power to the driver.
Start the pump
CAUTION:
• Immediately observe the pressure gauges. If discharge pressure is not quickly
attained, stop the driver, reprime, and attempt to restart the pump.
• Observe the pump for vibration levels, bearing temperature, and excessive noise. If
normal levels are exceeded, shut down the pump and resolve the issue.
Before you start the pump, you must perform these tasks:
• Open the suction valve.
• Open any recirculation or cooling lines.
1. Fully close or partially open the discharge valve, depending on system conditions.
2. Start the driver.
3. Slowly open the discharge valve until the pump reaches the desired flow.
4. Immediately check the pressure gauge to ensure that the pump quickly reaches the
correct discharge pressure.
5. If the pump fails to reach the correct pressure, perform these steps:
a) Stop the driver.
b) Prime the pump again.
c) Restart the driver.
6. Monitor the pump while it is operating:
a) Check the pump for bearing temperature, excessive vibration, and noise.
b) If the pump exceeds normal levels, then shut down the pump immediately and
correct the problem.
7. Repeat steps 5 and 6 until the pump runs properly.
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.
22 Series e-1510 Installation, Operation, and Maintenance Manual
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. Failure to do so can cause liquid to freeze and damage the pump.
Shut down the pump
1. Slowly close the discharge valve.
2. Shut down and lock the driver to prevent accidental rotation.
Commissioning, Startup, Operation, and Shutdown
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.
You must check the final alignment after the pump and driver are at operating
temperature. For initial alignment instructions, see the Installation chapter.
1. Run the unit under actual operating conditions for enough time to bring the pump,
driver, and associated system to operating temperature.
2. Shut down the pump and the driver.
3. Remove the coupling guard.
See Remove the coupling guard in the Maintenance chapter.
4. Check the alignment while the unit is still hot.
See Pump-to-driver alignment in the Installation chapter.
5. Reinstall the coupling guard.
6. Restart the pump and driver.
Note on the packed pump operation
Tighten the gland nuts
Before you start the pump, back off the packing gland nuts or screws until the gland is
loose.
Hand tighten until the gland is snug against the
freely run from the packing. This is normal and should be allowed to continue for a period

of time before you continue to tighten the gland. Tighten the gland nuts slowly and one
flat at a time.
Leakage rate
An adequate leakage rate is not one single value for all pumps and installations, but is the
amount required to provide adequate cooling and lubrication. The required leakage is
influenced by operating pressure, fluid temperature, shaft speed, and so forth. For fluid
temperatures in the range of 32°F to 190°F (0°C to 88°C), average leakage rates of 60 to
80 drops per minute are recommended. However, each individual pump and installation
has unique operating conditions that result in widely-variable leakage rate requirements.
Maximum fluid temperature
At fluid operating temperatures near the upper limit of 190°F (88°C), the maximum
temperature rise of the leakage is important. Never operate a packed pump with steam
forming at the gland. This limits the temperature rise to a maximum of about 20°F (-7°C). If
the formation of steam persists at higher leakage rates, you must provide cooling water by
means of an external supply, or a heat exchanger used to cool the bypass flush.

The bearing temperature usually rises 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.
Lubricating grease requirements
NOTICE:
• Never mix greases of different consistencies (NLGI 1 or 3 with NLGI 2) or with different
thickeners. For example, never mix a lithium-based grease with a polyurea-based
grease. This can result in decreased performance.
• Remove the bearings and old grease if you need to change the grease type or
consistency. Failure to do so can result in equipment damage or decreased
performance.
Specifications
• Regrease the pump while the pump is running.
• Regrease the pump bearing with NLGI grade 2 lithium base petroleum grease.
• Regrease the pump every 2500 operating hours or every six months.
• Lubricate the motor per the motor manufacturer's instructions.
• Always keep the pump and motor properly lubricated.

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:
• Review the pump hydraulic selection data and consult your local Xylem representative
to select the proper reduced diameter.
• For the 1510-4AD model, before trimming the impeller refer to the e-1510-4AD angle
cut guidelines.
• The recommended machining insert is Sandvick CNMG 432-1125 or equal without
coolant at 250 surface feet per minute (SFM) (76.2 surface meter per minute (SMM)).
• To calculate the spindle speed (RPM), use the formula RPM=(SFM*12)/(3.1416*
diameter of cut, in.) (RPM=(SMM*39.37)/(3.1416* diameter of cut, mm/25.4)). This
results in the following:
Impeller Maximum Diameter Recommended Maximum Spindle Speed (RPM)
7 in. (177.8 mm) 136
9.5 in. (241.3 mm) 100
11 in. (279.4 mm) 87
13.5 in. (342.9 mm) 71
• Recommended rough cut feed rate per revolution is 0.008 in. (0.20 mm) and depth of
cut is 0.050 in (1.27 mm).
• Recommended finish cut feed rate per revolution is 0.015 in. (0.38 mm) and depth of
