READ AND FOLLOW
SAFETY INSTRUCTIONS!
This is the safety alert symbol. When you see
this symbol on your pump or in this manual, look
for one of the following signal words and be alert to the
potential for personal injury:
warns about hazards that will cause
serious personal injury, death or major
property damage if ignored.
warns about hazards that will or can
cause serious personal injury, death or
major property damage if ignored.
warns about hazards that will or can
cause minor personal injury or property
damage if ignored.
The label NOTICE indicates special instructions which
are important but not related to hazards.
Carefully read and follow all safety instructions in
this manual and on pump.
Keep safety labels in good condition.
Replace missing or damaged safety labels.
LOCATION:
Locate the pump as near to the water source as
practical. Make the suction pipe run short and straight
with as few pipe fittings as possible to keep total friction
loss to a minimum.
Install pump in a clean, dry and well drained location if
possible and protect against moisture and adverse
weather conditions. Pump should be located on a level,
hard surface to prevent shifting or tipping. Locate to be
readily accessible for inspection and maintenance.
Careful attention should be taken to assure that Net
Positive Suction Head Available (NPSHA) exceeds Net
Positive Suction Head Required (NPSHR) by the pump
or reduced performance and severe pump damage may
result.
Figure 1, Page 4, illustrates where these terms (NPSHA
/ NPSHR) come from, and how to determine if the
pumping conditions at which you want to operate meet
the proper criteria. When in doubt, consult your nearest
Berkeley Professional Dealer.
NOTE: If pump site is 1000 feet above sea level, sub-
tract 1.2 feet from the NPSHA equation and an ad-
ditional 1.2 feet for each additional 1000 feet of eleva-
tion.
General Safety
Do not allow pump, piping, or any other system
component containing water to freeze. Freezing may
damage system, leading to injury or flooding. Allowing
pump or system components to freeze will void
warranty.
Pump approved liquids only with this pump.
Periodically inspect pump and system components.
Wear safety glasses at all times when working on
pumps.
Keep work area clean, uncluttered and properly lighted;
store properly all unused tools and equipment.
Keep visitors at a safe distance from the work areas.
Rotating parts. Can catch
hands, feet, or clothing.
Stay clear of equipment and

General Information
Installation
Page 4 F00637
FOUNDATION:
Refer to illustration on page 5.
Heavy weights; risk of crushing toes or
feet. Use care and proper lifting equipment when
handling pump for installation. Size and weight of some
units will require hoists for safe handling.
Pump should be set on a concrete foundation which is
sufficiently substantial to absorb vibration and which
provides a permanent and rigid support.
When properly positioned, the unit will be level, and the
suction and discharge openings of the pump will be
aligned with system piping.
PIPING:
System piping should be at least one commercial pipe
size larger than pump connections and flow velocity
should not exceed eight (8) feet per second. Suction and
discharge pipes must be naturally aligned with pump
connections.
NOTICE: Misalignment of piping with pump case or
excessive pipe strain can cause distortion of pump
components resulting in rubbing, breakage and reduced
pump life.
Insure that piping is supported in a manner that prevents
the exertion of force on pump connections. This can be
checked by the following procedure. With the pump shut
down, remove pipe flange bolts. If the mating flanges
come apart or shift, misalignment is present and causing
pressure on the connections. Adjust pipe supports until
flanges mate without any force. This procedure can be
done throughout piping system.
SUCTION PIPING:
Refer to illustrations on Page 8 through Page 11 for
recommended and not recommended practices in
suction connections.
DISCHARGE PIPING:
Refer to illustrations on Pages 12 and 13 for recom-
mended and not recommended practices in discharge
connections.
ELECTRICAL CONNECTION:
If electric motor is used.
NOTE: All wiring should be done by a qualified
electrician.
Hazardous voltage. Can shock, burn, or
cause death. Disconnect power to pump before
servicing.
Check voltage and phase stamped on pump motor
nameplate before making wiring connections to
electrical system. Be sure they agree with your electric
current supply. They MUST be the same. If in doubt,
check with your local power company.
Refer to illustration on Page 14 for minimum recom-
mended pumping panel components that help safeguard
your pump during operation.

ALWAYS be in place when pump is running. Coupling
guard shown in phantom for pictorial clarity.
ALIGNMENT OF PUMP AND MOTOR SHAFT
• A flexible coupling (except for double universal joint
shaft) will not compensate for misalignment. After the
pump unit is fastened on the foundation, it is nec-
essary to see that the shafts of the pump and motor
are properly aligned.
• Each motor and pump foot should be shimmed to
avoid shifting or
soft foot.
COURSE ALIGNMENT
• By moving the entire unit, bring suction and discharge
openings of the pump into alignment with the system
piping. Pipes should align without force with the pump
(see Installation Section).
• Bring the pump and motor shaft into approximate
alignment by shifting or shimming the motor. Use a
straight edge to check alignment of the shafts.
• Use calipers, or a wedge thickness gauge to check
the distance between coupling halves. The distance
between halves should be equal at 90 degree
intervals around the coupling, and the shafts should
be concentric when checked with a straight edge.
FINE ALIGNMENT
• Angular and parallel misalignment of the coupling
may be corrected simultaneously. Maintain a sep-
aration between coupling halves, per manufacturer’s
specifications, to avoid preloading of pump and motor
bearings.
• Check and account for indicator sag.
• Clamp dial indicators to the pump and motor shaft as
shown above.
• Start with angular alignment and finish check with
parallel alignment.
• Rotate both the shaft and coupling together by hand.
Note the total indicated runout shown on indicator “A”.
The maximum allowable angular misalignment is 1
degree. Limits of reading on indicator “A” at various
distances from shaft centerline are shown in Table I.
• Continue to rotate both shafts by hand and note the
runout shown on indicator “B”. The maximum allow-
able total indicated runout is .005 inches. Should
either angular or parallel misalignment exceed the
value shown, shift or shim the motor until mis-
alignment is within the allowable limits shown. Do not
move pump unless absolutely necessary. When
shimming, be sure that all feet on the pump and
motor are equally supported to avoid strains on the
castings when the hold down bolts are tightened.

ALIGNMENT
Drive belt can catch and trap clothing
or body. Belt guard must ALWAYS be in
place when pump is running. Belt guard is not shown for
pictorial clarity.
• Drive and pump shaft centerlines (A) must be parallel
as shown. Belt centerlines (B) must be straight as
shown.
• When installing belts, move the driver toward the
pump to allow belts to be placed on pulley. Then,
move the driver away from pump to obtain proper belt
tension as described below.
TENSION
• Multiple belt spans must be equal tension in all belts.
Proper belt tension varies with the size of belt being
used, however a general rule is:
Belts are properly tensioned when one belt can be
depressed one belt thickness at the center of the
span when pressing with thumb.
Another method is that a properly tensioned belt can
be rotated (twisted) one-quarter revolution at the
center of span.
NOTICE: Belts must be tight enough to prevent slip-
ping during operation. Loose belts result in early belt
failure and reduced performance. However, excessive
tightness of belts will result in overheating of the belts
and excessive bearing load in the pump and driver.
• Most Vee-belts will stretch slightly after initial
installation. After a short period of operation, re-
check belt tension and adjust as necessary.

CHECK ROTATION:
Before pump is put into operation, rotational direction
must be checked to assure proper performance of
pump. Refer to illustration on Page 16.
Hazardous voltage. Can shock, burn, or
cause death. Disconnect power to pump before
servicing.
Do not attempt any wiring changes without first
disconnecting power to pump.
PRIMING:
Pump priming is the displacement of air with water in
the pump and suction piping. Pump MUST BE
completely filled with water when operating.
Refer to Page 17 for instruction on the following
conditions:
1. Suction lift with priming pump (water source
below pump).
2. Suction lift with foot valve (water source below
pump).
3. Flooded suction (water source above pump, or
incoming water pressure is greater than
atmospheric pressure).
SPECIAL CASE - HYDRAULIC BALANCED PUMPS:
Hydraulic balanced pumps operate with a very low
positive pressure across the stuffing box, permitting a
much looser fit of the packing rings around the shaft
sleeve to control the loss of water from the pump
through the stuffing box. Because of the looser fit of
the packing rings, air can be more easily drawn into the
pump through the stuffing box when priming the pump
with an air evacuation type primer.
A grease fitting, aligned with the lantern ring in the
packing set, is provided to grease-seal the stuffing box
and minimize air leakage during priming.
If pump cannot be primed due to air leakage through
stuffing box, DO NOT tighten packing. Instead, pump
NLGI No. 4 Water Pump Grease into lantern ring until
back pressure occurs forcing grease into the lantern
ring, grease-sealing the stuffing box. After priming,
when unit is put into operation, the grease will be
flushed out through the packing by the water flowing
outward through the stuffing box. Proceed with normal
adjustment of the packing as described on Page 18.
Note that the grease seal only is used for control of air
leaking during priming, and that only the packing gland
is used to control flow of water through the stuffing box
during normal operation.
When necessary to replenish the grease supply use an
NLGI no. 4 Water Pump Grease.
STARTING:
NOTICE: Never run pump dry. Running pump without
water will overheat pump and damage internal parts.
Always make sure pump is primed prior to start-up.
NOTICE: Refer to maintenance section if pump has
packing for adjustment prior to start-up.
Prime pump by one of the above procedures. Set
discharge valve to minimum flow. Turn on power to
pump. Slowly open discharge valve until desired flow
rate is achieved. Place the “Hand-Off-Auto” selector
switch in the “Auto” position. The pump will be started
automatically when the pilot device signals the motor
starter.
STOPPING:
Pump will stop automatically when the pilot device de-
energizes the motor starter. Turn the “Hand-Off-Auto”
selector switch to “Off” position if you want to stop the
pump while it is running. If hydraulic shock occurs, the
check valve closure rate may need adjustment or
additional controls may be needed.

• Electric Motors:
Single Phase: Refer to wiring information on the
motor plate to obtain proper rotation.
Three Phase: If pump runs backwards, reverse any
two leads coming off incoming power (L1, L2, L3)
until proper rotation is obtained. Reverse L1 and L2,
or L2 and L3, or L1 and L3.
• Pump running backward - Centrifugal pumps will still
pump liquids, however, GPM and head will be a
fraction of the published performance.
• Engine Driven:
If engine is used for pump driver, check with engine
instruction and operation manual or engine man-
ufacturer to determine how rotation is defined, then
use above illustration for proper connection.

LUBRICATION:
LIQUID END of pump requires no lubrication. Wear
rings, packing rings, and models using a mechanical
shaft seal, are lubricated by the liquid being pumped. Do
not run dry!
BEARING FRAME - add approximately 2 ounces of a
lithium-based NGLI No. 2 extra pressure ball bearing
grease to each bearing during quarterly inspection.
NOTE: Excess grease will cause bearings to run hot.
The following are factory approved brands of grease for
use with Berkeley Pumps: Alvania EP2, Shell Oil;
Mobilith AW2, Mobil Oil, Ronex MP, Exxon, Litholine
EP2, Atlantic Richfield; and Amolith EP2, Amoco.
NOTE: Grease fitting in packing area is for priming only.
See
PRIMING
in start-up section for instruction.
ELECTRIC MOTOR: Refer to motor manufacturer’s
operating manual for complete instruction.
GAS/DIESEL ENGINE: Refer to engine manufacturer’s
operating manual for complete instruction.
PERFORMANCE CHECK:
Periodically check the output of the pump. If perform-
ance is noticeably reduced, refer to Troubleshooting
Chart.
OBSERVATIONAL MAINTENANCE:
When the pump and system operation have been
stabilized, verify that pump unit is operating properly.
Observe the following:
VIBRATION: All rotating machines can be expected to
produce some vibration, however, excessive vibration
can reduce the life of the unit. If the vibration seems
excessive, discontinue operation, determine cause of
the excessive vibration, and correct.
NOISE: When the unit is operating under load, listen
closely for unusual sounds that might indicate that the
unit is in distress. Determine the cause and correct.
OPERATING TEMPERATURE: During operation, heat
is dissipated from the pump and the driver. After a
short period of time, the surface of the pump bracket
will be quite warm (as high as 150°F), which is normal.
If the surface temperature of the pump bracket or
driver is excessive, discontinue operation, determine
cause of the excessive temperature rise, and correct.
Bearings will run hotter for a brief run-in period after
packing which is normal. However, worn bearings will
cause excessive temperatures and need to be
replaced. The pump unit is cooled by the water flowing
through it, and will normally be at the temperature of
the water being pumped.
STUFFING BOX: After a short period of operation,
verify that the stuffing box area and gland are not hot.
If heating is detected, loosen the gland nuts evenly
until water is just running out of stuffing box in a
DROPLET
form (approximately 40-60 drops per
minute). Water must not be streaming or spraying out.
Verify cool operation periodically. Adjust gland nuts
EVENLY
as necessary for lubrication and cooling of
the packing. If packing has been tightened to the limit
of the packing gland travel, additional packing is
necessary.
PACKING:
Starting new pump.
Before starting pump for the first time, loosen gland nuts
and retighten finger tight. Proceed with pump start-up
procedure. Allow packing to leak liberally for a few
moments. Then tighten gland nuts one complete turn
each until leakage is reduced to 40 to 60 drops per
minute.
REPACKING:
Refer to illustrations on Page 19.
MECHANICAL SEAL:
Adjustment or maintenance is normally not required.
The seal is enclosed within the pump and is self
adjusting. Seal is cooled and lubricated by the liquid
being pumped. Consult factory for proper replacement
procedure.
PUMP PROTECTION-
COLD WEATHER/
WET WEATHER INSTALLATIONS:
SYSTEM DRAINS: Provide drain valves to empty
system, including pump case, to prevent freezing
damage.
SHELTER: If possible, provide shelter for unit to protect
from weather. Allow adequate space around pump unit
for service. When effectively sheltered, a small amount
of heat will keep temperature above freezing. Provide
adequate ventilation for unit when running. For severe
weather problems, where other shelter is not practical, a
totally enclosed fan-cooled enclosure can be considered
for electric motors.
CONDENSATION: When the temperature of metal parts
is below dew point and the surrounding air is moist,
water will condense on the metal surfaces and can
cause corrosion damage. In severe situations, a space
heater can be considered to warm the unit.

• Install new packing rings in stuffing box by placing over
shaft sleeve and pushing them in as far as they will go.
• Rotate ring joint 90 degrees when installing each ring as
shown.
• Slide packing gland into position (gland must enter stuffing
box bore) then gently and evenly tighten nuts to force rings
into place and seat (do not over tighten). Loosen nuts again
to hand tight.
• Start primed pump and allow packing to leak liberally.
• While pump is running, evenly tighten gland nuts one
complete turn at a time until leakage is reduced to droplet
form (40 to 60 drops per minute).
• Unfasten hardware holding packing gland in place and slide
back on shaft to expose packing rings. A split packing gland
with threaded studs is shown.
• Remove packing rings from stuffing box using two com-
mercially available packing hooks as shown.
• Slide lantern ring (if used) back to expose any remaining
rings, including metallic. Remove them in the same manner.

GENERAL
• Shaft assembly of bearing frame pumps should be
periodically (annually minimum) torn down for inspection of
worn parts, cleaning, and re-greasing. Most importantly, to
check shaft sleeve and bearings for pitting. Replace worn
components as necessary. Parts may be ordered sepa-
rately as required, or for some models, shaft kits are
available that are completely assembled and ready for
installation.
PUMP DISASSEMBLY
• Remove packing gland and packing arrangement as
described in Page 19.
• Remove pump volute and impeller as described on Pages
20 and 21.
• Remove outer bearing cap and slide shaft assembly from
bearing bracket.
• Clean and inspect all components.
SHAFT INSTALLATION
• Thoroughly steam clean or solvent wash the bearing cavity
of bracket to remove old grease and dirt. Check surface of
bracket for cracks, extreme corrosion, or other defects.
• Pack bearings with a lithium-based NLGI No. 2 extra
pressure ball bearing grease. Force enough grease into
each bearing to fill internal space between the races.
• Coat the bearing bores of bracket with oil. Orient shaft
assembly in the direction shown above. Slide shaft and
bearing assembly into bearing bracket.
Do not force them!
When end of pump shaft comes through inside opening of
bearing cavity, place oil seal, water slinger, and lantern ring
over end of shaft. If packing gland or seal retainer is not of
the split variety, place it over the shaft at this time as well.
Slide shaft on through stuffing box until the first bearing
makes contact with the bracket. Carefully align bearing with
the bearing bore and press or tap bearing assembly into
place. Do not use excessive force.
NOTE: Be sure bearing bores and bracket area are clean and
free of contamination or early bearing failure may occur.
• Reinstall outer bearing cap and oil seal.
• Rotate pump by hand, 10-12 rotations.
• Reassemble pump parts and reinstall unit to piping system.

Procedure and parts may vary
slightly depending on pump model.
ROUTINE MAINTENANCE
A well maintained pumping system will extend the life of
the unit and will require fewer repairs. This means less
down time which can be very critical when a constant
delivery of water is required.
A routine maintenance and inspection schedule should
be set up on a weekly, quarterly, and annual basis with
records kept of these actions. For weekly checks see
observational maintenance on Page 18. For quarterly
and annual maintenance, refer to check list on the
following page. Copy page as necessary for continual
usage.
RECOMMENDED SPARE PARTS
It is recommended that the following spare parts be kept
on-site as a minimum back-up to service your pump and
reduce down-time. Check your model/style against parts
breakdown drawing on Page 25 when selecting spares.
• Mechanical Shaft Seal
• Packing Set and Packing Hooks
• Shaft Sleeve(s)
• All Gaskets and O-Rings Required for One Pump
• Impeller Wear Ring
• Retaining Rings
If having a pump non-operational has severe con-
sequences, a back-up pump should be considered.
Otherwise, a back-up impeller, volute case, bearings
and shaft, would be prudent.
WINTERIZING
If pump is to be out of service for an extended period of
time, such as the winter months, the following storage
procedures should be followed.
• Remove exterior dirt and grime or any substance that
may trap moisture. Exposed metal is subject to
oxidation, prime and repaint if necessary. If this is not
possible, coat with grease or heavy oil.
• Flush suction and discharge lines. Check for leaks at
this time and replace any worn gaskets.
• Remove lowest plug in pump and drain pump casing
and suction and discharge lines.
• Lubricate bearings.
• If possible, keep unit clean and dry during storage
period to guard against corrosion.
• Seal all open ports to keep out foreign objects such
as insects, rodents, dust and dirt.
• Rotate driver shaft periodically to prevent freeze-up of
internal components.
• Shelter unit from elements if possible.
• Work oil into impeller wear ring by dripping oil into the
gap while rotating by hand.
SPRING START-UP
• Inject sufficient grease into the bearings to displace
old grease.
• Visual inspection.
• Rotate by hand, if any binding occurs, disassemble
and inspect.
