MAINTENANCE SAFETY DATA:
Warning: Toxic Fluid Handling
Hazardous or toxic fluids must be flushed and properly
disposed of before performing service to the pump. Check
local and national regulations on disposal regulations
for your area. Clean all contaminated parts according to
local and national regulations. Isolate pump by closing
the suction and discharge valves before servicing the
pump. Wear personal protective equipment when there is a
potential of handling hazardous or toxic materials.
Warning: Relieve Pressure
Relieve system pressure prior to servicing the pump. Failure
to do so can cause personal injury or property damage.
Use quality fasteners (OEM supplied) of proper size and
material. Do not use force to draw piping flanges to pump
as this may cause dangerous strains within the pump case
and misalignment between the pump and driver. Do not
disassmble or adjust any pressure containing component or
shaft seal prior to relieving the pressure from the primary
and auxiliary fluid systems. This will ensure no hazardous
or high pressure fluid is ejected causing personal injury or
equipment damage.
OPERATIONAL SAFETY DATA:
CAUTION
Do not exceed rated pressures. Do not operate under
minimum rated flow. Do not operate with discharge or
suction valves closed. Do not adjust or disassemble any
pressure containing component or shaft seal prior to
depressurizing the system.
Warning:
Do not operate unless the suction is primed with fluid.
Never run pump dry. Do not operate without liquid supplied
to the mechanical seal. Running the mechanical seal dry
(even for limited runs) can cause failure and fluid release.
Personal injury can occur.
CAUTION
Do not touch the pump while it is connected to hot or
cold fluids. Doing so could cause personal injury.
Warning: Cut Power
Lock out power to the driver prior to performing work
on the pump. Accidental start could occur if power is not
locked out, causing personal injury. Always wear proper
safety equipment including glasses, gloves, shoes and
respirators. Do not touch pump while in operation. Lockout
or uncouple driver prior to personal contact with unit. Be
careful of any odd shaped or sharp edges. Avoid contact
with the rotating components in the seal chamber area. All
adjustments to the pump shoul be made with the pump shut
and locked out.
Danger: Do Not Heat to Loosen
Do not apply heat for removal or disassembly as any
trapped fluid could ignite causing an explosion.
CAUTION
Lifting/Handling of Unit
Lift the unit with a device that is capable of lifting the
weight of the combined pump components.
NOTICE: This pump is intended for fluid transfer. Do not
use for any other purpose than the intended applications.

INTRODUCTION:
RECEIVING SHIPMENT: Upon receiving shipment, check
items against packing list. Be sure to inspect entire box for any
additional parts and read all special instruction tags attached to
the pump.
STORAGE: If the unit will not be installed immediately, the
unit should be kept dry and in the shipping container until ready
for installation.
HANDLING:
CAUTION
Heavy pumps and components. Serious injury or damage
to the equipment could result from improper lifting and
support.
You may hoist the isolated pump using the eyebolt in the
bearing frame. If the pump is mounted on a baseplate, place a
sling under the motor end and a sling under the pump end to
hoist. If the pump and baseplate also contain a motor you may
hoist by placing a sling under the motor end and a sling under
the pump end.
FOUNDATION: The foundation must maintain alignment
under normal and abnormal conditions as this is one of the most
controlling aspects for the overall reliability of the pump. The
foundation must be as heavy as possible and nonresonant so it
can minimize vibration. The length and width of the foundation
should project beyond the anchor bolts at least 6" (152mm)
while considering a generous factor of safety when determining
the thickness of the base.
Certified pump elevation drawings can be supplied. These
drawings will include general information on determining the
size and thickness of the base and dimensions for locating the
anchor bolts.
Anchor bolts must be accurately situated and provided with
sleeves. The sleeve bore diameter should be nearly double
the diameter of the bolt, providing no less than .5" (13mm)
clearance around the bolt.
Use an acceptable foundation for pump installation.

•Operate the pump and driver for an adequate amount of time
to achieve maximum operating temperature before the final
or hot alignment is performed.
•Repeated checks of alignment should be performed to
ensure proper, smooth and continuous operation.
•If any changes occur in process conditions it is
recommended to perform an alignment check.
Warning:
Typical Foundation
LEVELING: Acceptable parallel machined bearing plates or
chock blocks need to be placed under the base along the sides
and ends to distribute the load evenly. These must be leveled,
lengthwise and widthwise, before installation of the base can
begin.
GROUTING: The anchor bolts are for hold-down only.
The grouting withstands end thrust and side thrust while
compensating for the nonuniformity between the base and the
foundation, preventing the pump from shifting.
Use nonexpanding, nonshrinking and high strength grouting
mixture.
Allow proper setting of grouting before tightening anchor bolts.
Check coupling alignment after tightening to ensure it has
not changed. Realign as required in the Coupling Alignment
instructions.
COUPLING ALIGNMENT:
Warning:
Always lock out electrical power to the driver before
performing alignment. Failure to lock out power could
result in serious injury.
NOTICE: Check rotation direction of the driver before
coupling it to the pump. The front surface of the pump
casing has indications of rotation direction. Damage to the
pump will occur if the direction of rotation is not correct.
Good alignment through the flexible coupling will result in
good service life of the driver and pump.
COUPLING INFORMATION:
•Use flexible type coupling for motor and pump.
•When aligning the shafts, the coupling should be
disconnected and the halves should be brought into
alignment.
ALIGNMENT CHECKS:
•Check cold alignment before and after grout has been
applied to the baseplate.
•Prior to cold alignment piping should be connected to the
pump.
Install coupling guard once alignment is completed. Ensure
coupling guard is properly installed before operating the
pump.
NOTICE: Inspect the alignment between the pump
and driver to ensure no misalignment was caused in the
transportation and handling of the unit.
Do not align if base and mounting flanges have not been
tightened. Perform alignment when the pump and driver are at
normal operating temperatures.
ALIGNMENT METHOD: There are many ways to ensure
proper alignment, and specific alignment choices are the
customer’s choice. If you require information on the double dial
indicator method, contact the Aurora factory for details. Check
Hydraulic Institute Standards for additional information.
ALIGNMENT CRITERIA: Complete alignment occurs
when the unit’s parallel and angular Total Indicator Run-out
(TIR) measures less than .005" (.13mm). Measure the parallel
alignment on the rim of the coupling, and the angular alignment
on the face of the coupling. Corrections need to be made if any
values exceed those stated.
Warning:
Never use force to draw piping to pump flanges. This can
cause excess strain on the pump case and misalignments
can occur between the pump and driver resulting in serious
injury and damage to the equipment.
Check Hydraulic Institute Standards for proper piping details.
PIPING FORCES AND MOMENTS: The discharge
and suction piping flanges must be aligned concentric and
parallel to the pump flanges. All piping must be independently
supported near the pump to eliminate any forces that could
be transmitted to the pump after the nuts and bolts have been
securely fastened. Always tighten bolts 180° across from
each other in an alternating fashion to ensure even gasket
compression.
The piping system must be designed to allow for thermal
expansion while not creating excessive forces on the pump due
to the expansion/contraction, or the weight of the pipe and fluid.
NOTICE: Do not draw the piping to the pump by force.
Excess forces and moments on the pump will reduce seal
and bearing life.
5
3500 SERIES / MODEL 3550
Excess forces and moments on the pump may occur due to:
•Thermal expansion and contraction of the piping indicating
improper piping design and/or lack of expansion joints or
loops.
A straight length of suction piping at least five times the
diameter of the pipe is recommended directly in front of the
suction flange.
•Improper pipe support due to use of rod hangers (instead of
spring hangers), anchors or restraints used when installing
the piping.
SOURCE
•Misalignment of the pump suction and discharge flanges to
the piping flanges.
SUCTION PIPING:
•Suction piping should not be less than the size of the pump
suction nozzle. Suction piping should be no more than one
size larger than the pump suction nozzle.
5 DIAMETERS
Piping for elevated source should be in one plane. A straight
length of suction piping at least five times the diameter of the
pipe is recommended directly in front of the suction flange.
•Suction line velocities should not exceed 10 ft./sec. This
will prevent cavitation of the pump.
•Fluid velocity guidelines are 4 to 6 ft./sec. for suction and 6
to 10 ft./sec. for discharge.
•Pressure drop across permanent suction strainers needs to be
considered when calculating pump inlet suction pressure.
•Tee branches and valve stems must be installed
perpendicular to the pipe centerline. Installing them parallel
is incorrect.
NPSH: The pump must have enough positive suction head
to prevent cavitation. The NPSH available (NPSHa) must be
greater than the NPSH required (NPSHr). To locate NPSHr
information, refer to the pump’s performance curve.
5 DIAMETERS
Problems may occur if the elbow bolts directly to the pump’s
suction. The liquid tends to follow the longer radius, creating a
void or reverse flow along the shorter radius, which starves part
of the impeller.
For submerged suction, the inlet must be located deep enough
to prevent vortexing. If needed to prevent the formation of a
vortex, provide vortex breakers in the suction vessel.
NOT RECOMMENDED
The suction piping must be free of all air pockets. An eccentric
reducer may be used to reduce the chances of air pockets
forming if joining different sizes of suction piping.
NOTICE: Never control the pump flow by throttling a valve
in the suction line. The only function of the suction valve is
to isolate the pump from the system for maintenance.
Avoid situations where there are many elbows in many planes.
A straight length of suction piping (at least five times the
diameter of the pipe) is recommended directly in front of
the suction flange. Never insert an elbow directly in front of the
suction flange.
All elbows in suction piping should be long radius.
NOT RECOMMENDED
When operating from the same supply source, separate suction
lines are recommended.
Suction strainers need to have a total free area of at least three
times the suction piping area.
REDUCERS:
•Suction piping is usually no more than one diameter larger
than pump suction nozzle.
6
3500 SERIES / MODEL 3550
ORIENTATION:
•For suction above centerline: Eccentric – Flat side on
bottom. Concentric.
SUCTION
Install an isolation valve to prevent the pump, at start-up, from
running in excess of the pump curve by throttling while the
system is being filled. The isolation valve is also used to isolate
the pump for maintenance.
Undersized valves can cause excessive flow restriction. Install
reducers between the check valve and the pump to prevent this.
If system demands require long periods of near shut-off
operation, a recirculation line should be installed. Install the
recirculation line off the discharge line, which returns to the
supply reservoir below the liquid level. Install a valve or orifice
in the bypass line to regulate flow. An automatic valve may
be needed to regulate flow or to prevent excessive stops and
starts. Automatic valves are needed especially when using large
motors.
Quick acting valves should be installed to protect the pump
from surges and water hammer in the system.
SUCTION
MECHANICAL SEAL:
Warning:
•For suction below centerline: Eccentric – Flat side on top.
Concentric not recommended.
PIPING INSTALLATION:
•To minimize friction losses, piping runs should be as short
as possible.
•Flanges should be concentric allowing the bolts to be
inserted into the flange holes with finger pressure only. Do
not use spud wrenches or come-a-longs to align the flange
holes.
•To prevent excessive nozzle loads, piping should be
anchored, restrained and supported separate from the pump,
near the suction and discharge.
•Limit parallelism of the flange gasket surfaces to .002"/in.
of normal pipe size with a maximum parallelism of .03".
Never operate the pump without liquid supplied to the
mechanical seal. Running the mechanical seal dry, even for
short periods, can cause seal damage and/or failure. Physical
injury can occur if mechanical seal fails.
The mechanical seal is flushed and cooled by the pumped fluid
or an external source. If using an external source, the media
must be clean, solid-free and compatible with the pumped fluid.
Quench, vent and/or drain ports are available as seal options.
Make proper connections when required by the application.
Always follow all seal instructions.
BEFORE PUMP OPERATION:
Confirm that:
•All set screws are tightened to the shaft.
EXAMPLE USING 4" PIPE:
•All centering clips are removed.
4 x .002" = .008" max.
•All required mechanical seal auxiliary systems are properly
installed and connected.
•3" and under pipe sizes are flexible. These allow a .008"
maximum out-of-parallelism without causing shaft
alignment problems.
•Be sure to have the pump grouted and aligned prior to
connecting the last 20' of piping to the pump suction and
discharge.
•To monitor movement when the piping is bolted up, install
dial indicators from the driver to the pump. The maximum
acceptable movement is .002".
•Tighten flange bolt to 2/3 torque using crisscross pattern for
first pass. Finish the final bolt torque in a clockwise pattern.
DISCHARGE PIPING: Install a check valve between the
isolation valve and the pump to protect the pump from running
backward when it is shut down.
Because seal life is dependent on a variety of factors
(cleanliness of process, operating conditions, etc.), it is difficult
to predict seal life for a given application.
LUBRICATION:
BEARING OIL LUBE: Fill pump bearing frame with high
quality, antifoaming turbine oil. Oil should contain rust and
oxidation inhibitors.
SUGGESTED OILS:
Mobil DTE Heavy Medium
Royal Purple Synfilm IOS VG 68 (synthetic)
Shell Turbo NO. T68
Shell Omala 68
Texaco Regal R + O NO. 68

BEARING GREASE LUBE: Choose premium quality
lithium grease. The grease should have an NLGI 2 or 3
consistency and a base oil viscosity of 68 centistokes minimum
at 40°C. Pregrease the bearings after assembly onto the shaft
when reassembling the pump. Pack the bearings full with
grease; pack the bearing housing adjacent to the bearings onethird (1/3) to one-half (1/2) full.
BEARING FRAME: Use the optional cooling coil for water
cooling of the bearing frame. The cooling coil is required only
when the pumped media temperature surpasses 400°F (204°C)
at 1800 RPM or 300°F (149°C) at 3600 RPM. Under these
conditions, ambient temperature water at 1–3 gallons/minute
(.23 to .68 m3/hr.) is required for appropriate cooling of the oil.
To keep the oil temperature below the maximum recommended,
higher flows may be necessary.
Turn on the cooling water before allowing the hot process fluid
to enter the pump.
SEAL CHAMBER: Water jacketed seal chambers are
available. Requirements for the jacket are based on the type of
mechanical seal and selection of elastomers.
Ambient temperature water at 2–3 gallons/minute (.45 to .68
m3/hour) is required for appropriate cooling of the seal chamber
when a jacket is installed.
A jacket is recommended for any application over 350°F
(177°C). Consult the factory for specific recommendations.
SEAL FLUSH: The seals may be cooled and/or heated 1)
from an external source or 2) by passing pump discharge
fluid through a heat exchanger and then into the seal flush
connection. A double seal may use cooled/heated barrier fluid
from an external source or convection system.
Always follow all required seal operating instructions as listed
in the seal instruction booklet.
OPERATION:
NOTICE: Never mix greases of different consistencies.
START-UP INSPECTION:
SUGGESTED GREASES:
Chesterton #615
SKF LGMT2/LGMT3
REGREASING INTERVALS: For back-to-back angular
contact, single and double row bearings, add several shots of
grease from a grease gun at the following intervals:
RPM
Hourly Interval
1180 RPM
5000 hours
1750 RPM
4000 hours
3550 RPM
1250 hours
Bearings need regreasing more frequently at bearing
temperatures above 150°F (66°C). Halve greasing intervals
for every 27°F (15°C) increase. Grease temperature should not
exceed 185°F (85°C). Replace the grease completely at every
third regreasing interval or at least once a year minimum.
NOTICE: Overgreasing is the most common cause of
bearing overheating and contributes to premature bearing
failure.
COUPLING LUBRICATION: Consult the coupling
manufacturer’s instructions for lubrication information.
TEMPERATURE CONTROL:
NOTICE: Normal operating oil temperature should be
below 160°F (71°C) and should NEVER surpass 180°F
(82°C).
8
Warning:
Lock out driver to prevent accidental start-up and physical
injury.
1.Check Installation. Examine the entire pump package for
proper alignment. Confirm that all auxiliary systems are
connected and ready for use.
2.Check Rotation Direction.
NOTICE: Improper rotation direction will damage the
pump.
The coupling must be totally disconnected from the pump
and driver when checking for proper rotation direction.
Operate the driver independently to check for proper
rotation. The pump rotation should be clockwise when
viewed from the coupling end. The rotation direction is
distinguished by an arrow on the front of the casing.
3.Check Impeller Clearance.
NOTICE: Setting impeller clearance is crucial
for maintaining maximum pump efficiency. Be sure
to compensate for additional thermal growth in high
temperature applications. Consult Appendix I (page 22)
of the manual to set impeller clearance.
Set impeller clearance.
3500 SERIES / MODEL 3550
a.When making adjustments, unseat the mechanical seal
from the shaft.
b.Check total clearance. Confirm that it follows the given
instructions.
c.Set the proper operating clearance on the suction side of
the impeller.
Increase the clearance on the suction side of the impeller if
the pumpage temperature exceeds 100°F (38°C). Consult
Appendix I Table I of the manual for proper instructions.
4.Check Rotating Element. To confirm a free-rotating
element, turn the shaft by hand several times (there will be a
degree of resistance due to the bearings and the mechanical
seal). Do not attempt to operate the pump if any rubbing
noise occurs during this process. Instead, readjust the
impeller clearance as outlined in Appendix I, then reset the
mechanical seal according to its instructions.
5.Check Lubrication. Inspect the pump, motor and coupling
for proper lubrication.
AUXILIARIES START-UP: The unit’s auxiliary components
must be turned on where applicable before priming and starting
the pump. Do not start the pump / motor until all the auxiliary
systems are fully operating.
BEARING FRAME COOLING: Turn on the water to the
cooling coil in the bottom of the oil sump if applicable. For
proper flow requirements, consult page 8 of the manual.
MECHANICAL SEAL: Turn on the flush, quench or barrier
fluid to the mechanical seal if applicable. Regulate pressure
and flow according to the seal manufacturer's installation
instructions. Turn on the heating/cooling fluid if the seal flush
includes a heat exchanger.
SEAL CHAMBER JACKET: Turn on the water to the
cooling jacket attached to the seal chamber. For proper flow
requirements, consult page 8 of the manual.
PRIMING:
The pump is now ready to be primed.
1.Close the pump discharge valve.
2.Open the pump suction valve.
Warning:
Never operate the pump dry. It is important that the pump
never be subjected to thermal shock. The liquid must be
allowed to enter the pump casing slowly. A centrifugal
pump should never be started until all parts have
been gradually brought to the ultimate intended pump
temperature.
3.Confirm that all vent and/or ejector connections are closed
after priming.
START-UP:
NOTICE: Before start-up, confirm that the shaft turns
freely by hand (clockwise when facing the coupling end).
Open the suction valve completely. Start the pump with the
discharge valve open approximately 20% before gradually
opening the valve until reaching design flow point. The
discharge valve should be adjusted to achieve proper process
flow, operating as close to the BEP as possible. The suction line
should not be throttled or restricted at all during the operation.
PUMP PERFORMANCE: Once started, confirm that
the pump is running at or close to the operating point on
the pump performance curve. Throttle the discharge valve if the
pump is overloading the motor or delivering too much flow. A
restriction orifice at the pump discharge may be necessary to
control pump capacity.
Monitor all the flows and pressures to the auxiliary components
and adjust accordingly.
Check the mechanical seal and all other connections for
potential leakage. Tighten where necessary.
Shut down the pump when it has run for one hour and is at
maximum operating temperature. Then, turn the shaft by hand
(in the direction of the rotation arrow) to establish that the
rotating element is not binding and the impeller is not rubbing.
Also check the shaft alignment. Consult page 5 for coupling
alignment.
Danger:
Never operate the pump below minimum rated flow and/or
with the discharge valve closed. These operating conditions
could cause extreme temperature rise in the pump and an
explosive hazard. Also, premature failure can result due to
high radial loads and excess vibration.
SHUTDOWN:
To shut down the pump:
1.Turn off the pump and de-energize the motor. Be sure motor
is locked out before attempting to work on the pump.
Warning:
Lock out driver to prevent accidental start-up and physical
injury.
2.Close the discharge valve and the suction valve.
3.Drain the pump casing.
4.Turn off all auxiliary components in the reverse order from
start-up.
5.To prevent damage from freezing in cold weather, the
entire pump (including all auxiliary components) should be
completely drained.

(370C), jacking bolts (370D) and locking nuts (423) when
.030" (.76mm) clearance is reached.
NOTE: The above steps approximate the impeller
position when set at .015" (.38mm) from casing.
6.Check impeller run-out by checking vane tip to vane tip.
Total indicator reading greater than .005" (.13mm) indicates
a problem. Take steps to resolve problem before continuing.

APPENDIX II: COUPLING GUARDS INSTALLATION
INSTRUCTIONS:
Warning:
Before assembly or disassembly of the coupling guard
is performed the motor must be de-energized, the motor
controller/starter put in a locked-out position and a caution
tag placed at the starter indicating the disconnect. Replace
coupling guard before resuming normal operation of the
pump. Pump manufacturer assumes no liability if this
requirement is not followed.
Simple design allows complete assembly of the coupling guard
in about 15 minutes, including assembly of the end plate (pump
end). Assembly can be accomplished in about five minutes if
the end plate is already in place.
ASSEMBLY:
NOTE: If end plate (pump end) is already installed, make
any necessary coupling adjustments and proceed to Step 2.
1.S, M, L Models: Align end plate (pump end) to
bearing frame (no impeller adjustment required).
XL Model: Align end plate (pump end) to pump bearing
housing so that 1) large slots on end plate clear bearing
housing tap bolts and 2) small slots are aligned to impeller
adjusting bolts. Attach end plate to bearing housing using
jam nuts on impeller adjusting bolts.
Check and reset impeller clearance after end plate is
attached to bearing housing.
NOTE: Complete coupling adjustments before
proceeding with coupling guard assembly.
2.Spread bottom of coupling guard half (pump end) slightly
and place over pump end plate (the annular groove in the
guard half is located around the end plate).
22
3500 SERIES / MODEL 3550
3.Once coupling guard half (pump end) is located around end
plate, tighten it securely with a bolt, nut and two washers
through the round hole at front end of guard half.
4.Spread bottom of coupling guard half (driver end) slightly,
then place over coupling guard half (pump end). Check that
annular groove in coupling guard half (driver end) faces
motor.
5.Place end plate (driver end) over motor shaft. Locate end
plate in annular groove at rear of coupling guard half (driver
end), then hand-tighten with a bolt, nut and two washers
through the round hole at rear of guard half.
6.To completely cover shafts and coupling, adjust length
of coupling guard by sliding coupling guard half (driver
end) toward motor. Secure with bolt, nut and two washers
through slotted holes at center of guard and tighten. Inspect
all nuts on guard assembly for proper tightness.
Warning:
Before assembly or disassembly of the coupling guard
is performed, the motor must be de-energized, the motor
controller/starter put in a locked-out position and a caution
tag placed at the starter indicating the disconnect. Replace
coupling guard before resuming normal operation of the
pump.
DISASSEMBLY: Remove the coupling guard for certain
maintenance and adjustments to the pump. Specific instances
include adjustment of the coupling, impeller clearance
adjustment, etc. The coupling guard must be replaced after
completing maintenance procedures.
DO NOT resume pump operation with the coupling guard
removed.
NOTE: For reverse order assembly, refer to diagrams.
1.Remove nut, bolt and washers from center slotted hole in
coupling guard. Slide motor end coupling guard half toward
pump.
2.Remove nut, bolt and washers from coupling guard half
(driver end) and remove end plate.
3.Spread bottom of coupling guard half slightly and lift off.
4.Remove remaining nut, bolt and washers from coupling
guard half (pump end). Spread bottom of coupling guard
half slightly and lift off.
Disassembly of the coupling guard is now complete.
NOTE: Bearing housing tap bolts are accessible without
removing end plate if maintenance of internal pump
parts is necessary. Therefore, it is unnecessary to remove
end plate (pump end) from pump bearing housing.

BEARING ISOLATORS:
The Aurora model 3550 pump comes with Impro® bearing
isolators. These labyrinth seals are highly effective at keeping
oil in the bearing frame while keeping contaminants out. The
drain hole must be at the bottom (6 o’clock position) for proper
operation. This seal has a theoretically infinite life as it is a noncontacting seal; however, it can be damaged through an outright
bearing failure in close clearance situations. The rotor is driven
by a replaceable O-ring which fits onto the pump shaft. The
stator OD is sealed with a replaceable O-ring. A third O-ring is
internal to the seal and cannot be replaced. Due to this, treat the
seal as an assembly and replace it as such if necessary.

component parts) must be promptly returned to Seller prior to any attempted repair, or sent to an authorized service station designated
by Seller, and Buyer shall prepay all shipping expenses. Seller shall not be liable for any loss or damage to goods in transit, nor will
any warranty claim be valid unless the returned goods are received intact and undamaged as a result of shipment. Repaired or replaced
material returned to customer will be shipped F.O.B., Seller's factory. Seller will not give Buyer credit for parts or equipment returned to
Seller, and will not accept delivery of any such parts or equipment, unless Buyer has obtained Seller's approval in writing. The warranty
extends to repaired or replaced parts of Seller's manufacture for ninety (90) days or for the remainder of the original warranty period
applicable to the equipment or parts being repaired or replaced, whichever is greater. This warranty applies to the repaired or replaced
part and is not extended to the product or any other component of the product being repaired. Repair parts of its own manufacture

workmanship under normal use and service. This warranty applies to the replacement part only and is not extended to the product or
any other component of the product being repaired. Seller may substitute new equipment or improve part(s) of any equipment judged
defective without further liability. All repairs or services performed by Seller, which are not covered by this warranty, will be charged in
accordance with Seller's standard prices then in effect.

BUYER WAIVES ALL OTHER WARRANTIES EXPRESSED, IMPLIED IN LAW OR IMPLIED IN FACT, INCLUDING
ANY WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Seller's sole obligation under
this warranty shall be, at its option, to repair or replace any equipment (or its component parts) which has a defect covered by this
warranty, or to refund the purchase price of such equipment or part. Under the terms of this warranty, Seller shall not be liable for (a)
consequential, collateral, special or liquidated losses or damages; (b) equipment conditions caused by normal wear and tear, abnormal
conditions of use, accident, neglect, or misuse of said equipment; (c) the expense of, and loss or damage caused by, repairs or alterations

a result of such submittal. All testing shall be done in accordance with Seller's standard policy under Hydraulic Institute procedures.
LIABILITY LIMITATIONS: Under no circumstances shall the Seller have any liability under the Order or otherwise for liquidated
damages or for collateral, consequential or special damages or for loss of profits, or for actual losses or for loss of production or progress
of construction, regardless of the cause of such damages or losses. In any event, Seller's aggregate total liability under the Order or
otherwise shall not exceed the contract price.
ACTS OF GOD: Seller shall in no event be liable for delays in delivery of the equipment or other failures to perform caused by fires,
acts of God, strikes, labor difficulties, acts of governmental or military authorities, delays in transportation or procuring materials, or
causes of any kind beyond Seller's control.
COMPLIANCE WITH LAW: Seller agrees to comply with all United States laws and regulations applicable to the manufacturing
of the subject equipment. Such compliance shall include: The Fair Labor Standards Acts of 1938, as amended; Equal Employment
Opportunity clauses of Executive Order 11246, as amended; Occupational Safety and Health Act of 1970 and the standards promulgated
thereunder, if applicable. Since compliance with the various Federal, State, and Local laws and regulations concerning occupational
health and safety, pollution or local codes are affected by the use, installation and operation of the equipment and other matters over
which Seller has no control, Seller assumes no responsibility for compliance with those laws and regulations, whether by way of
indemnity, warranty, or otherwise. It is incumbent upon the Buyer to specify equipment which complies with local codes and ordinances.
