Safety First

General Information

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:

DANGER warns about hazards that will cause

serious personal injury, death or major property
damage if ignored.

WARNING warns about hazards that will or can

cause serious personal injury, death or major
property damage if ignored.

CAUTION 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.

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.

WARNING

Rotating parts. Can catch
hands, feet, or clothing.

Stay clear of equipment and
keep shields in place while
pump is running.

Stop motor or engine before
servicing pump.

Read owner’s manual before
using equipment.

General Information

Installation

LOCATION

Locate the pump as near the water source as practical. Make
pipe run short, straight and with as few pipe fittings as pos­sible, to keep total friction loss to a minimum.

Install pump in a clean, dry and 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.

Because of the portable nature of this style pump, 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, 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, subtract 1.2
feet from the NPSHA equation and an additional 1.2 feet for
each additional 1000 feet of elevation.

PUMP FOUNDATION

CRUSHING WEIGHT. Models with larger

suction and discharge openings are extremely heavy. Use care
and proper equipment when handling pump for installation.

Be sure to allow for the weight of the water in the pump and
piping.

Portable Installation:

Pump should be placed on an area that will provide a solid
foundation substantial enough to support the weight of pump
and engine and also to provide stability while the pump is
running. Engine vibration will cause shifting on any type of
loose surface and cause piping strains and possible damage.

NOTICE: Settling and/or shifting during operation can cause
piping to place excessive strain on the pump and may
damage pump case.

Permanent Installation:

Pump and Engine should be set on a concrete foundation
which is sufficiently substantial to absorb vibration and which
will provide a permanent and rigid support. Bolt engine directly
to concrete.

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.

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. If ANSI type flange
connections are used, 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.

REQUIREMENTS FOR PROPER OPERATION

Pump End:

When delivering the required capacity (GPM) to the system
piping, the pump must add the amount of Head required by
the system at that capacity. The operating head-capacity point
should be as close as possible to the highest efficiency line
shown on the performance curve, and MUST be below the
head-capacity line labeled “Maximum” RPM. The maximum
operating RPM for the pump is determined by bearing life, or
in some cases, by the pressure limits of the pump. “The
maximum working pressure for NPT tapped and flanged
pumps, per ANSI B16.1 class 125, is 175 PSI unless
otherwise stated on the pump curve”. When used as a booster
pump, the pressure at the pump discharge (combination of
inlet pressure plus pressure added by the pump) must not
exceed the maximum working pressure shown. The Suction
NPSHA must be greater than the NPSHR shown on the pump
curve.

Engine:

The engine used to drive the pump must be suitable for the
application. It must produce adequate power for the pump
demand, and must rotate in the correct direction (standard
rotation is CLOCKWISE when viewed from the front of
engine).

Internal Combustion Engines are variable speed and variable
power machines. The power output depends upon the engine
speed (RPM) and will be reduced when operating altitude,

and/or the air temperature increases. When driving the pump
at the RPM required to deliver water into the system piping,
the engine must operate within the engine manufacturers
minimum and maximum RPM limits. The power output to
supply the pump power demand must not exceed the
CONTINUOUS POWER RATING of the engine, after derating
for all power consuming engine accessories, and adjustment
for installation site altitude and air temperature. Proper power
matching of the pump and engine is the responsibility of the
pump and engine unit assembler.

MATCHING PUMP END TO ENGINE

S.A.E. Bracket Size:

Type “B” engine drive pumps are available to fit engines
having a standard S.A.E. 5 through S.A.E. 1 flywheel housing.

For a new engine, the engine supplier can provide the S.A.E.
housing number.

For an existing engine, the flywheel housing bore and bolt
circle can be measured and compared against the standard
S.A.E. housing dimensions listed in Table I, to identify the
housing S.A.E. number.

• Measure the flywheel housing bore (A), and the bolt circle

(B), as accurately as possible with a tape measure (to the
nearest 1/32 inch).

• Count the number of threaded holes in the flywheel housing

(C). Test the threaded holes with a bolt, to determine the
thread series.

• Compare the measured dimensions (A), (B), and (C) against

Table I, to determine the S.A.E. number of the flywheel
housing, to be sure it matches the S.A.E. number of your
pump.

• Record measurements on the dimension form on Page

23 in the spaces provided under Flywheel Housing
Dimension.

FLYWHEEL COUPLING

The flywheel coupling transmits power from the engine
flywheel to the pump shaft. The maximum power that a
coupling can safely handle is shown by a rating number, “R”,
which is listed in the coupling dimensions tables.

When selecting a flywheel coupling for a pump and engine,
first determine the power rating that the pump will demand.
On the pump performance curve, find the RPM and BHP
values required to produce the application head-capacity
point.

Divide the BHP by the RPM, then multiply the result times

100. The result will be the

demand number

for the pump.

For example, a B6JQBM can deliver 1500 GPM
at 260 feet Total Head when running at 2200
RPM. The power required by the pump will be
120 BHP. The demand number will be:

(120/2200) x 100 = 5.45

Next, select a coupling that can safely transmit the power, and
which will fit the flywheel dimensions. For a coupling to be
suitable, it must have an “R” rating number

GREATER

THAN

the pump

demand number

. In the above example, the

minimum coupling “R” number would be 6.
NOTE: The isolator disc design of Berkeley flywheel

couplings provides smooth power flow from the engine to the
pump, and torsional vibration problems are rare. However,
with the broad range of engines available, a torsional
mismatch can occur, which can cause excessive stress in the
pump shaft and coupling.

Torsional compatibility of the engine, pump, and coupling is
the responsibility of the assembler. Berkeley Pumps will
supply data for the pump and coupling for use by the
assembler for a torsional analysis.

NOTE: If the flywheel is fitted with a pilot bearing pressed into
a bore at the center, remove it to avoid interference with the
pump shaft.

FLYWHEELS FOR INDUSTRIAL TYPE
OVERCENTER CLUTCHES

Figure 3 on the facing page, shows the hollowed-out
appearance of the flywheels made for use with overcenter
type Clutch Power Take-Off assemblies.

These flywheels will have a recessed bore machined into the
face, and a set of tapped holes, which will be used to attached
the coupling to the flywheel. Dimensions are governed by an
SAE standard and are listed in Tables IIA and IIB, Figure 3.
The “Clutch Size” shown in the table is the nominal clutch
facing diameter for Drive Ring Type Overcenter Clutches.

For a new engine, the engine supplier can furnish the dim­ensions.

For an existing engine, measure the flywheel dimensions, “D”
through “H”, using a tape measure and a machinists com­bination square. Measurements to the nearest 1/32” will
usually be adequate.

When dimensions match a standard flywheel coupling listed in
Tables IIA, IIB, and IIC, Figure 3, select the one that has an
“R” rating number greater than the pump demand number.

• Record measurements on the dimension form on Page

23 in the spaces provided under Flywheel Dimensions.

OTHER FLYWHEELS

Some engines are fitted with flywheels especially machined
for coupling to other kinds of machinery (electrical generators,
torque converters, etc.), and require nonstandard flywheel
couplings. If the measured flywheel dimensions do not
correspond to dimensions listed in Tables IIa or IIb, write the
measured dimensions into the Dimension Form provided on
page 23, and send it to Berkeley for quotation of special
flywheel coupling.

PREPARATION FOR ASSEMBLY
OF PUMP ON ENGINE

• Clean face and register fit of flywheel housing and flywheel
as necessary to remove all grease, dirt, or rust (and all
traces of rust preventative) which would interfere with
installation of pump and/or prevent correct alignment. If
flywheel is fitted with a pilot bearing for a transmission shaft,
remove and discard. The pilot bearing is not required for
installation of the pump end, and could interfere with the
pump shaft.

• Examine shaft spline closely. Use a file, if necessary, to
remove any burrs that would prevent coupling from sliding
freely onto the shaft.

• Lubricate pump shaft spline sparingly with light grease.

• Slide the coupling onto shaft until it is stopped against the
shaft.

• Measure the distance from the engine side of flywheel
coupling adapter ring to the mounting face of the pump
bracket. Refer to Figure 4 below, Dimension “A”.

• Next, measure depth from face of flywheel housing on
engine, to face on flywheel against which coupling will be
bolted. Refer to Figure 4 below, Dimension “B”.

Pump measurement must be less than engine measurement
or axial interference will result in thrust force on engine crank
shaft bearings. Simply stated, Dimension “A” must be less

than Dimension “B”.

INSTALLATION OF COUPLING ON FLYWHEEL

Flywheel Coupling Overcenter Type:

These couplings are aligned concentrically with the flywheel
by register fit on the flywheel.

Be sure to remove all preservatives from the engine’s
flywheel.

Fit the coupling into the flywheel. Align the bolt holes and
engage coupling with register fit on flywheel. Tap coupling
with a soft heavy hammer, if necessary, to be sure that it is
seated flat against flywheel. Secure coupling tightly to
flywheel with capscrews and lockwasher.

INSTALLATION OF PUMP ON ENGINE

• Lift pump with suitable lifting apparatus and align pump
shaft with coupling. End of pump shaft has a pilot diameter
which permits easy engagement of pump shaft into
coupling.

• Reach into pump suction opening and rotate impeller
slightly until the splines on the shaft will engage the
coupling. Verify that there is no gap between bracket and
flywheel housing faces. Rotate pump as necessary to align
bracket holes with engine. Install capscrews and bolt pump
end securely to engine.

NOTE: If any interference, or incompatibility of parts is
detected during installation, DO NOT proceed with
assembly. Direct the problem to your nearest Berkeley
Professional Dealer.

with water when operating.

Refer to Page 14 for instruction on the following conditions:

1. Suction lift with priming pump (water source below pump).

2. Suction lift with exhaust primer (water source below pump).

3. Suction lift with foot valve (water source below pump).

4. Flooded suction (water source above pump, or incoming
water pressure is greater than atmospheric pressure).

Special Case – Hydraulically Balanced Pumps

Packed Pumps:
Hydraulically balanced pumps operate at 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, communicating through the side of the
stuffing box to a lantern ring in the packing set, is provided to
grease-seal the stuffing box to prevent 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 17. 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 the
flow of water the stuffing box during normal operation.

When necessary to replenish the grease supply, use an NLGI
No. 4 Water Pump Grease.

Mechanically Sealed Pumps:
Mechanically sealed pumps require no special procedures

unless they are mounted vertically. In this case, call Berkeley
Customer Service at 1-888-237-5353 for more information.

STARTING

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.

Engine Operation

Refer to engine owner/operator manual supplied with pump for
starting and operating instructions.

Pump performance varies depending on engine RPM. Refer to
engine operators manual to adjust engine speed.

Risk of Engine Damage. Operating pump at
lower than rated head can cause excessive load on engine. In
addition, pump has the capability of overloading engine if
allowed to run continuously at an RPM or flow rate that is
above specified hydraulic performance.

Risk of pump damage. Operate the engine in
its preferred RPM range. Reduced RPM for long periods may
damage the pump liquid end.

Pump Operation

Prime pump by one of the previous described procedures.
Start engine. Slowly open discharge valve until desired flow
rate is achieved, or pump is operating against head for which it
was selected.

After pump is running, 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 a minute.

If pump is equipped with a rotary mechanical seal, no
adjustment is necessary.

Shutting Down

Close discharge valve to hold prime before stopping pump.
Valve should remain closed until pump/engine is restarted.
Reduce the engine RPM prior to shutting down to reduce
hydraulic shock (water hammer).

Pump Priming

Start-Up

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!

BRACKET: Add approximately 2 oz. of a lithium-based NLGI
No. 2 extra pressure ball bearing grease to each bearing
during quarterly inspection. Refer to pump parts drawing on
Page 24, grease fittings are labeled with a circled “L”.
Excessive grease will cause bearings to run hot.

NOTE: Grease fitting in packing area is for priming only. See

Priming

in start-up section for instruction.

The following brands of bearing grease are factory approved
by Berkeley Pumps and are recommended for use in main­tenance operations.

• Shell Brand Alvania Grease EP2

• Mobil Oil brand Mobilith AW#2

• Exxon Ronex MP

• Atlantic Richfield Litholine EP2

• Amoco Amolith EP2
ENGINE: Refer to engine manufacturer’s operating manual

for complete maintenance instructions.

PERFORMANCE CHECK

Periodically check the output of the pump. If performance 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, 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 near the bearings will
be quite warm (as high as 150° F), which is normal. If the
surface temperature of the pump bracket or engine is
excessive, discontinue operation, determine cause of
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
thorough 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

DROPLET

form (40 to 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 travel,
additional packing is necessary.

REPACKING

Refer to illustration on Page 17.

MECHANICAL SEAL

Adjustment or maintenance is not required. The seal is
enclosed within the pump and is self-adjusting. Seal is cooled
and lubricated by the liquid being pumped.

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.

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.

• Peel off old volute gasket (or O-Ring) and discard.
NOTE: Certain models such as the B4EY, are constructed

with a suction cover which is removed first to access impeller.

GENERAL

• Shaft assembly of S.A.E. mounted 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 sepa­rately 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 17.

• Remove pump volute and impeller as described on Pages
18 and 19.

• 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 (see “Lubrication”, Page 16).
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 threaded 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.

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 16. For quarterly and annual maintenance,
refer to check list on the following page. Copy page as
necessary for continual usage.

For engine maintenance refer to engine manufacturer’s
owners/operators manual.

RECOMMENDED SPARE PARTS

It is recommended that the following spare parts be kept on­site as a minimum back-up to service your pump and reduce
down time. Check your model/style against parts breakdown
drawings on Pages 24 and 25 when selecting spares.

• Mechanical Shaft Seal (or)

• 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 consequences, 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. Coat machined surfaces 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 the wear ring by dripping oil into the gap while
rotating impeller by hand.

• Winterize the engine according to the engine manufacturer’s
instructions.

SPRING START-UP

• Inject sufficient amount of grease into bearing to displace old
grease.

• Perform a visual inspection of all components.

• Rotate by hand to be sure impeller and shaft turn freely. If
binding occurs, disassemble and inspect.

• Follow engine manufacturer’s recommendations for starting
the engine.
