SECTION B: GENERAL INFORMATION
B-1) To The Purchaser:
Congratulations! You are the owner of one of the fi nest
pumps on the market today. Barnes® Pumps are products
engineered and manufactured of high quality components.
Over one hundred years of pump building experience
along with a continuing quality assurance program
combine to produce a pump which will stand up to the
toughest applications.
Check local codes and requirements before installation.
Servicing should be performed by knowledgeable pump
service contractors or authorized service stations.
The pump is packaged ready for installation and no
connections or adjustments are necessary except for
attaching discharge piping and plugging in service cord.
B-2) Receiving:
Upon receiving the pump, it should be inspected for
damage or shortages. If damage has occurred, fi le a claim
immediately with the company that delivered the pump.
If the manual is removed from the crating, do not lose or
misplace.
B-3) Storage:
Short Term- Barnes Pumps are manufactured for effi cient
performance following long inoperative periods in storage.
For best results, pumps can be retained in storage, as
factory assembled, in a dry atmosphere with constant
temperatures for up to six (6) months.
Long Term- Any length of time exceeding six (6) months,
but not more than twenty four (24) months. The units
should be stored in a temperature controlled area, a roofed
over walled enclosure that provides protection from the
elements (rain, snow, wind blown dust, etc..), and whose
temperature can be maintained between +40 deg. F and
+120 deg. F. Pump should be stored in its original shipping
container and before initial start up, rotate impeller by hand
to assure seal and impeller rotate freely.
B-4) Service Centers:
For the location of the nearest Barnes Service Center,
check your Barnes representative or Crane Pumps
& Systems, Inc., Service Department in Piqua, Ohio,
telephone (937) 778-8947 or Crane Pumps & Systems
Canada, Inc., Bramton, Ontario, (905) 457-6223.
SECTION C: INSTALLATION
C-1) Location:
These pumping units are self-contained and are
recommended for use in a sump or basin. The sump or
basin shall be vented in accordance with local plumbing
codes. This pump is designed to pump effl uent or
wastewater, nonexplosive and noncorrosive liquids and
shall NOT be installed in locations classifi ed as hazardous
in accordance with the National Electrical Code (NEC),
ANSI/NFPA 70 or Canadian Electric Code (CEC). Never
install the pump in a trench, ditch, or hole with a dirt
bottom; the legs will sink into the dirt and the suction will
become plugged.
C-1.1) Submergence:
The pump should always be operated in the submerged
condition. The minimum sump liquid level should never
be less than A Dimension, A = 3 inches on BP Series and
A = 6 inches on SE Series above the pump bottom. The
recommended level should not drop below the top of the
motor housing (see Fig. 1).
C-2) Discharge:
Discharge piping should be as short as possible. Both a
check valve and a shut-off valve are recommended for
each pump being used. The check valve is used to prevent
backfl ow into the sump. Excessive backfl ow can cause
fl ooding and/or damage to the pump. The shut-off valve
is used to stop system fl ow during pump or check valve
servicing.
C-3) Liquid Level Controls:
Figure 2 shows a typical installation for any submersible
pump using a level control mounted to the discharge piping
with a piggy-back plug.
FIGURE 1
6
General Comments:
1) Never work in the sump with the power on.
2) Level controls are factory set for a pumping differential
of 9 inches. If that is the cycle desired, simply circle
the discharge pipe with the pipe mounting strap, feed
the end through the worm drive, and tighten with a
screwdriver. Be certain that the level control cannot
hang up or foul in its swing. Also, make certain the
pump impeller is still submerged when the level control
is in the “OFF” mode.
3) If a higher pump differential is needed, grip the cord
near the neck of the fl oat, then using the other hand,
exert a steady force on the lower edge of the cable
clamp. The cable clamp should slide up to the new
pivot point. Attach the level control to the discharge
hose in the manner described above.
4) Plug the level control plug into the GFI receptacle,
then plug the pump into the piggyback plug. One cycle
of operation should be observed, so that any potential
problems can be corrected.
5) It is recommended that the fl oat should be set to
insure that the sump well liquid level never drops
below the top of the motor housing or a minimum level
of 3 inches on BP Series and 6 inches on SE Series
above the pump bottom.
6.) Figure 3 shows a typical connection for pumps with the
wide angle fl oat and piggy-back plug, for manual and
automatic operations.
Automatic - Plug fl oat cord into GFI outlet, then plug pump
cord into fl oat cord.
Manual - Plug pump cord directly into GFI outlet.
C-4) Electrical Connections:
C-4.1) Power Cable:
The cord assembly mounted to the pump must not be
modifi ed in any way except for shortening to a specifi c
application. Any splice between the pump and the control
panel must be made in accordance with the electric codes.
It is recommended that a junction box, if used, be mounted
outside the sump or be of at least NEMA 4 (EEMAC-4)
construction if located within the wet well. Do not use the
power cable to lift pump. NOTE: THE WHITE WIRE IS
NOT A NEUTRAL OR GROUND LEAD, BUT A POWER
CARRYING CONDUCTOR.
C-4.2) Overload Protection:
Single Phase - The type of in-winding overload protector
used is referred to as an inherent overheating protector
and operates on the combined effect of temperature and
current. This means that the overload protector will trip out
and shut the pump off if the windings become too hot, or
the load current passing through them becomes too high.
It will then automatically reset and start the pump up
after the motor cools to a safe temperature. In the event
of an overload, the source of this condition should be
determined and rectifi ed immediately. DO NOT LET THE
PUMP CYCLE OR RUN IF AN OVERLOAD CONDITION
OCCURS !
If current through the temperature sensor exceeds the
values listed, an intermediate control circuit relay must
be used to reduce the current or the sensor will not work
properly.

SECTION: D START-UP OPERATION
D-1) Check Voltage and Phase:
Before operating pump check to make sure that the
voltage and phase information stamped on the pump’s
identifi cation plate matches the available power.
D-2) Check Pump Rotation:
Before putting pump into service for the fi rst time, the
motor rotation must be checked. Improper motor rotation
can result in poor pump performance and can damage
the motor and/or pump. To check the rotation, suspend
the pump freely, momentarily apply power and observe
the “kickback”. “Kickback” should always be in a counter-
clockwise direction as viewed from the top of the pump
(“kickback” is always opposite to impeller rotation).
“Rotation” and “kickback” direction is noted on the pump
motor housing.
D-2.1) Incorrect Rotation for Single-Phase:
In the unlikely event that the rotation is incorrect for a
single-phase pump, contact a Barnes Pumps Service
Center.
D-3) Identifi cation Plate:
Record the numbers off the pump’s identifi cation plate
onto the START-UP REPORT provided at the end of the
manual for future reference.
D-4) Start-Up Report:
Included at the end of this manual are two start-up report
sheets. These sheets are to be completed as applicable.
Return one copy to Barnes Pumps and store the second
in the control panel or with the pump manual if no
control panel is used. It is important to record this data at
initial start-up since it will be useful to compare to when
servicing the pump in the future.
Insulation Test:
Before the pump is put into service, an insulation (megger)
test should be performed on it. The ohm values as well
as the volts and amps should be recorded on the start-up
sheet and stored safely in the control panel or with the
pump manual if no control panel is used.
Pump-Down Test:
After the pump has been properly wired and lowered into
the basin, sump, or lift station, it is advisable to check
the system by fi lling with liquid and allowing the pump
to operate through its pumping cycle. The time needed
to empty the system, or pump-down time, should be
recorded on the start-up sheet.
SECTION E: PREVENTATIVE MAINTENANCE
As the motor is oil fi lled, no lubrication or other
maintenance is required, and generally Barnes pumps will
give very reliable service and can be expected to operate
for years on normal sewage pumping without failure.
However, as with any mechanical piece of equipment a
preventive maintenance program is recommended and
suggested to include the following checks:
1) Inspect motor chamber for oil level and contamination
and repair as required per section F-1.
2) Inspect impeller and body for excessive build-up or
clogging and repair as required per section F-2.
3) Inspect bearing and replace as required per section F-3.
4) Inspect seal for wear or leakage and repair as required
per section F-4.
SECTION F: SERVICE AND REPAIR
NOTE: All item numbers ( ) refer to Figures 10 & 11.
F-1) Lubrication:
Anytime the pump is removed from operation and at least
every twelve (12) months, the cooling oil in the motor
housing (12) must be checked visually for oil level and
contamination.
F-1.1) Checking Oil:
To check oil, set unit upright. Remove pipe plug (24). With
a fl ashlight, visually inspect the oil in the motor housing
(14) to make sure it is clean, clear and that the oil level is
above all internal componentry. If oil appears satisfactory,
replace pipe plug. If oil is low or appears contaminated,
test oil as per section F-1.2
F-1.2) Testing Oil:
1. Place pump on it’s side, remove pipe plug (24) and
drain oil into a clean, dry container.
2. Check oil for contamination using an oil tester with a
range to 30 kilovolts breakdown.
3. If oil is found to be clean and uncontaminated
(measures above 15 KV. breakdown), refi ll the motor
housing as per section F-1.3.
4. If oil is found to be dirty or contaminated (or measures
below 15KV. breakdown), then the pump must be
carefully inspected for leaks at the shaft seal (3),
cord inlet (9), o-ring (13), and pipe plug (24)
before refi lling with oil. To locate the leak, perform a
pressure test as per section F-1.4. After leak is
repaired, refi ll with new oil as per section F-1.3.

F-1.3 Replacing Oil in Motor Housing:
Drain all oil from motor housing and dispose of properly.
Refi ll with 58 ounces of new cooling oil as per Table 1. An
air space must remain in the top of the motor housing to
compensate for air expansion. Set unit upright and fi ll only
until oil level from top of pipe plug boss is 3” ± 1/4”.
When refi lling with oil after servicing the shaft seal (3), a
pressure test as per section F-1.4 should be done. If shaft
seal was not disturbed during service, then apply pipe
sealant and replace the pipe plug (24).
WARNING ! - DO NOT overfi ll oil. Overfi lling of
motor housing with oil can create excessive
and dangerous hydraulic pressure which
can destroy the pump and create a hazard.
Overfi lling oil voids warranty.

F-1.4) Pressure Test:
Before checking the pump for leaks around the shaft
seal, square ring, and cord inlet, the oil level should be
full as described in section F1.3. Apply pipe sealant to the
pressure gauge assembly and tighten into fi ll plug hole
(see Figure 4). Pressurize motor housing to 10 P.S.I.
Use a soap solution around the sealed areas and inspect
joints for “air bubbles”. If, after fi ve minutes, the pressure
is still holding constant, and no “bubbles” are observed,
slowly bleed the pressure and remove the gauge
assembly. Replace the pipe plug using a sealant. If the
pressure does not hold, then the leak must be located.
F-2) Impeller and Volute Service:
F-2.1) Disassembly and Inspection:
To clean out body (20), or to replace impeller (17),
disconnect power, remove hex bolts (21), and vertically lift
motor and seal assembly from body (20). Clean out body

or wear and replace if required. Inspect gasket (19) and
replace if cut or damaged. The impeller (17) is threaded
onto the shaft and to remove, unscrew impeller, holding
shaft with a large screwdriver. Remove exclusion seal (16)
and replace if needed.
F-2.2) Reassembly:
Before installing impeller (17), inspect threads on shaft
and impeller to assure that they are clean. Place exclu-
sion seal on shaft with the thin lip toward the motor (see
section F-4.3). Apply a thread-locking compound to shaft
threads and screw impeller onto shaft and tighten. Rotate
impeller to check for binding. Position gasket (19) on body
and install impeller and motor housing on pump body.
Apply thread locking compound to each cap screw (21),
thread into body, and torque to 11 ft. lbs. Check for free
rotation of impeller.
F-3) Motor, Bearing and Cable Service
F-3.1) Disassembly and Inspection:

Check capacitor (7) with an Ohm meter by grounding the
capacitor by placing a screwdriver across both terminals
and then removing the screwdriver. Connect Ohm meter
(set on high scale) to terminals, if needle moves to infi nity
( ∞ ) then drifts back, the capacitor is good. If needle does
not move or moves to infi nity ( ∞ ) and does not drift back,
replace capacitor (7).
Bearings - Disassemble motor as per section F-3.1.
Remove snap ring (6) with snap ring pliers and pull motor
(1) and lower bearing (4) straight off of seal plate (2).
Inspect all parts for signs of wear and replace as needed.
CAUTION! Handle seal parts with extreme
care. do not scratch or mar lapped surfaces.
F-3.2) Replacing Bearing:
When replacing bearing, be careful to not damage the
rotor or shaft threads. Press the old bearing off the
shaft with an arbor press or gear puller. Clean the shaft
thoroughly. Apply adhesive compound to shaft and press
new bearing on, pushing only on the inner race, until it
seats against shoulder of shaft (see fi g.8).
IMPORTANT! - All parts must be clean before
reassembly.
F-3.3) Reassembly:
Make sure shaft seal (3) is clean and in proper position as
per section F-4.2 before reassembling rotor and bearing.
Slide lower bearing and rotor shaft squarely into the seal
plate (2) until bearing seats on the bottom. Insert snap
ring (6) into seal plate with fl at edge against outer race of

F-4) Shaft Seal Service
F-4.1) Dissassembly and Inspection:
Disassemble pump motor as per section F-3.1. Inspect
seal for signs of wear such as uneven wear pattern on the
stationary member or chips and scratches on either sealing
face. Do not interchange seal components. Replace entire
seal if damage occurs.
F-4.2) Replacing Shaft Seal (refer to fi g. 7, 8 & 9):
When replacing the shaft seal (3), remove used rotating
member (3c), spring (3b), and spring retainer (3a) from
motor shaft. Press used stationary member (3d) from the
seal plate (2). At reassembly, clean seal cavity thoroughly
and apply a light coat of oil. Lightly oil the rubber ring (DO
NOT use grease) and press the stationary member fi rmly
into the seal plate using a seal pusher (See Parts List- Seal
Tool Kit), nothing but pusher to come in contact with seal
face (see Fig. 7). Insert so that the fi nished surface is up
and the grooved surface is against the seal plate.
Make sure the stationary member is in straight and that the
rubber ring is not out of it’s groove.
DO NOT HAMMER ON THE SEAL PUSHER - IT
WILL DAMAGE THE SEAL FACE.
Place spring retainer and spring onto motor shaft. Lightly
oil shaft (DO NOT use grease) and inner surface of
bellows of rotating member. With fi nished end away from
motor, slide rotating member over bullet and onto shaft
until it engages spring (see Fig. 9). Carefully assemble
shaft to seal plate as per section F-3.3. It is extremely
important to keep seal faces clean during assembly. Dirt
particles lodged between these faces will cause the seal
to leak. When seal plate is assembled to motor, it will
properly align and seat the seal (3) and bearing (4). Follow
complete reassembly instructions as per section F-3.3.
F-4.3) Replacing Exclusion Seal:
The exclusion seal (16), helps to keep debris away from
the shaft seal where it could cause damage. The exclusion
seal should be replaced whenever the shaft seal is
replaced. To replace the exclusion seal, pull the old seal off
the shaft, and slide the new seal on with the thin lip toward
the motor. Be sure not to damage the lip of the seal. Finger
pressure is all that is needed to install the exclusion seal.

If the system fails to operate properly, carefully read instructions and perform maintenance recommendations.
If operating problems persist, the following chart may be of assistance in identifying and correcting them:
MATCH “CAUSE” NUMBER WITH CORRELATING “CORRECTION” NUMBER.
NOTE: Not all problems and corrections will apply to each pump model.
PROBLEM CAUSE CORRECTION
Pump will not run 1. Poor electrical connection, blown fuse,
tripped breaker or other interruption of power,
improper power supply.
2. Motor or switch inoperative (to isolate
cause, go to manual operation of pump).
2a. Float movement restricted.
2b. Switch will not activate pump or is defective.
2c. Defective motor
3. Insuffi cient liquid level.
1. Check all electrical connections for
security. Have electrician measure current
in motor leads, if current is within ±20%
of locked rotor Amps, impeller is probably
locked. If current is 0, overload may be
tripped. Remove power, allow pump to cool,
then recheck current.
2a. Reposition pump or clean basin as
required to provide adequate clearance for
fl oat.
2b. Disconnect level control. Set ohmmeter
for a low range, such as 100 ohms full scale
and connect to level control leads. Actuate
level control manually and check to see that
ohmmeter shows zero ohms for closed switch
and full scale for open switch. (Float Switch).
2c. Check winding insulation (Megger Test)
and winding resistance. If check is outside
of range, dry and recheck. If still defective,
replace per service instructions.
3. Make sure liquid level is at least equal to
suggested turn-on point.
4. Recheck all sizing calculations to
determine proper pump size.
5. Check discharge line for restrictions,
including ice if line passes through or into
cold areas.
6. Remove and examine check valve for
proper installation and freedom of operation.
7. Open valve.
8. Check impeller for freedom of operation,
security and condition. Clean impeller and
inlet of any obstruction.
9. Loosen union slightly to allow trapped air
to escape.Verify that turn-off level of switch
is set so that the suction is always fl ooded.
Clean vent hole.
10. Check rotation. If power supply is three
phase, reverse any two of three power supply
leads to ensure proper impeller rotation..
11. Repair fi xtures as required to eliminate
leakage.
12. Check pump temperature limits & fl uid
temperature.
13. Replace portion of discharge pipe with
fl exible connector.
14. Turn to automatic position.
15. Check for leaks around basin inlet and
outlets.
Pump will not turn off 2a. Float movement restricted.
2b. Switch will not activate pump or is defective.
4. Excessive infl ow or pump not properly sized
for application.
9. Pump may be airlocked
14. H-O-A switch on panel is in “HAND” position
Pump hums but does not run 1. Incorrect voltage
8. Impeller jammed or loose on shaft, worn or
damaged, impeller cavity or inlet plugged.
Pump delivers insuffi cient capacity 1. Incorrect voltage.
4. Excessive infl ow or pump not properly sized
for application.
5. Discharge restricted.
6. Check valve stuck closed or installed backwards.
7. Shut-off valve closed.
8. Impeller jammed or loose on shaft, worn or
damaged, impeller cavity or inlet plugged.
9. Pump may be airlocked.
10. Pump running backwards
Pump cycles too frequently or runs
periodically when fi xtures are not in use
6. Check valve stuck closed or installed
backwards.
11. Fixtures are leaking.
15. Ground water entering basin.
Pump shuts off and turns on indepen-
dent of switch, (trips thermal overload
protector). CAUTION! Pump may start
unexpectedly. Disconnect power supply.
1. Incorrect voltage.
4. Excessive infl ow or pump not properly sized
for application.
8. Impeller jammed, loose on shaft, worn or
damaged, impeller cavity or inlet plugged.
12. Excessive water temperature.
(internal protection only)
Pump operates noisily or vibrates
excessively
2c. Worn bearings, motor shaft bent.
8. Debris in impeller cavity or broken impeller
10. Pump running backwards
13. Piping attachments to buiding structure too
rigid or too loose.
