Recommendations and Warnings
Receiving inspection
Upon receiving the pump, it should
be inspected for damage or
shortages. If damage has occurred,
file a claim immediately with the
company that delivered the pump. If
the manual is removed from the
packaging, do not lose or misplace.
Storage
Any product that is stored for a
period longer than six (6) months
from the date of purchase should be
bench tested prior to installation. A
bench test consists of, checking the
impeller to assure it is free turning
and a run test to assure the motor
(and switch if provided) operate
properly.
Controls
Manual models require a separate
approved pump control device or
panel for automatic operation. Be
sure the electrical specification of the
control selected properly match the
electrical specifications of the pump.
Submergence
The pump should always be
operated in the submerged
condition. The minimum sump liquid
level should never be less than above
the pump’s volute (See Figure 1).
Installation
These pumps are recommended for
use in a sump, basin or lift station.
The sump, basin or lift station shall
be sealed and vented in accordance
with local plumbing codes. This
pump is designed to pump
sewage, effluent or wastewater,
non-explosive and non-corrosive
liquids and shall NOT be installed
in locations classified as hazardous
in accordance with the National
Electrical Code (NEC) ANSI/NFPA
70 or Canadian Electric Code (CEC).
The pump should never be installed
in a trench, ditch, or hole with a dirt
bottom. The legs will sink into the
dirt and the suction will become
plugged.
The installation should be at a
sufficient depth to ensure that all
plumbing is below the frost line. If
this is not feasible, remove the check
valve and size the basin to
accommodate the additional
backflow volume.
Pumps are most commonly installed
in simplex or duplex stations or
basins with a slide rail system
(Barmesa SRC), which allows the
pump(s) to be installed or removed
without requiring personnel to enter
the station, or resting on the basin
floor.
Discharge Piping
Discharge piping should be as short
as possible and sized no smaller than
the pump discharge. Do not reduce
the discharge pipe size below that
which is provided on the pump.
Both a check valve and a shut-off
valve are recommended for each
pump. The check valve is used to
prevent backflow into the sump. The
shut-off valve is used to manually
stop system low during pump
servicing.
Liquid Level Controls
The level control(s) should be
mounted on the discharge piping, a
cable rack or float pole. The level
control should have adequate
clearance so it cannot hang up in it’s
swing and that the pump is
completely submerged when the
level control is in the "Off " mode. By
adjusting the cord tether the control
level can be changed. One cycle of
operation should be observed, so
that any potential problems can be
corrected.
Electrical Connections
Power cable:
The power cable mounted to the
pump must not be modified in any
way except for shortening to a
specific 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 a minimum Nema 4
construction if located within the wet
well. DO NOT USE THE POWER
CABLE TO LIFT PUMP.
It is recommended that the level
control float should be set to insure
that the liquid in the sump never
drops below the top of the motor
housing or a minimum level of 10
inches above the basin floor.
Always rely upon a Certified
Electrician for installation.

Overload Protection:
Three Phase - The Normally Closed
(N/C) thermal sensor is embedded in
the motor windings and will detect
excessive heat in the event an
overload condition occurs. The
thermal sensor will trip when the
windings become too hot and will
automatically reset when the pump
motor cools to a safe temperature. It
is recommended that the thermal
sensor be connected in series to an
alarm device to alert the operator of
an overload condition, and/or the
motor starter coil to stop the pump.
In the event of an overload, the
source of this condition should be
determined and repaired.
These situations may induce a false
signal in the moisture detecting
circuit. If none of the above test
prove conclusive, the pump(s) should
be pulled and the source of the
failure repaired. IF A MOISTURE
DETECT HAS OCCURRED
MAINTENANCE SHOULD BE
PERFORMED AS SOON AS
POSSIBLE!
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.

Wire Size:
If longer power cable is required
consult a qualified electrician for
proper wire size.
Pre-Operation
1.Check Voltage and Phase -
Compare the voltage and phase
information stamped on the
pump name plate.
2.Check Pump Rotation - Improper
motor rotation can result in poor
pump performance and can
damage the motor and/or pump.
Check rotation on three phase
units by momentarily applying
power and observe the "kickback".
Kickback should always be in a
counter-clockwise direction as
viewed from motor end or opposite
to impeller rotation. Impeller rotation
is counter-clockwise as viewed from
bottom of pump.
3.Name Plate - Record the
information from the pump name
plate to drawing in front of manual
for future reference.
4.Insulation Test - An insulation
(megger) test should be performed
on the motor. Before the pump is put
into service. The resistance values
(ohms) as well as the voltage (volts)
and current (amps) should be
recorded.
5.Pump-Down Test - Be sure pump
has been properly wired, lowered
into the basin, sump or lift station,
check the system by filling with liquid
and allowing the pump to operate
through its pumping cycle. The time
needed to empty the system, or
pump-down time along with the
volume of water, should be recorded.
04
Installation & Service
DO NOT ALLOW THE
PUMP TO CYCLE OR RUN IF AN
OVERLOAD CONDITION OCCURS.
WARNING
Moisture Sensors - A normally open
(N/O) sensor rated of 1 watt @330K
ohms, 500 volt, is installed in the
pump seal chamber which will detect
any moisture present. It is
recommended that this detector be
wired in series to an alarm device or
motor starter coil to alert the
operator that a moisture detect has
occurred. In the event of a moisture
detect, check the individual moisture
sensor probe leads for continuity, (∞
resistance = no moisture) and the
junction box/control box for
moisture content.
No lubrication or maintenance is
required. Perform the following
checks when pump is removed from
operation or when pump
performance deteriorates:
Maintenance
barmesapumps.com
a)Inspect motor chamber for oil
level and contamination.
b)Inspect impeller and body for
excessive build-up or clogging.
c)Inspect motor, bearings and shaft
seal for wear or leakage.

Cooling Oil - Anytime the pump is
removed from operation, the cooling
oil in the motor housing should be
checked visually for oil level and
contamination. To check oil, set unit
upright. Remove cap screws (6), lift
conduit box assembly (4) from motor
housing (3), Do Not disconnect
wiring from motor leads. With a
flashlight, visually inspect the oil in
the motor housing (3) to make sure it
is clean and clear, light amber in color
and free from suspended particles.
Milky white oil indicates the presence
of water. Oil level should be just
above the motor when pump is in
vertical position.
Seal Chamber - Drain oil from seal
chamber by placing pump on its
side with pipe plug (18) downward
and remove pipe plug (18). If the oil
is found to contain considerable
water or other contamination, the
shaft seal (19) should be inspected
and replaced if required.
After leak is repaired, dispose of old
oil properly, and refill with new oil.
Use soap solution around the sealed
areas above the oil level and inspect
joints for "air bubbles". If, after five
minutes, the pressure is still holding
constant, and no "bubbles" /oil
seepage is observed, slowly bleed the
pressure and remove the gauge
assembly. Replace oil. Leek must be
located and repaired if pressure does
not hold.
Seal Chamber - Check that seal
chamber is full of oil by removing
pipe plug (18). Apply pipe sealant to
pressure gauge assembly and tighten
into hole in bearing housing (16).
Pressurize seal chamber to 20-25 PSI
and check for leaks.
Oil Replacement - Set unit upright
and refill with new cooling oil as per
table. Fill to just above motor as an air
space must remain in the top of the
housing to compensate for oil
expansion. Reassemble the o-ring (5)
and conduit box (4) to motor housing
(3). Apply thread locking compound
to cap screws (6) and place into holes
and torque to 15 ft/lbs.
Oil Replacement:
Seal Chamber - Refill chamber
completely full with new cooling oil
or reuse the uncontaminated oil.
NOTE: Item numbers in ( ) refer to
Figures 6.
Servicing ŸIf oil is found to be dirty or
contaminated (or measures below
15 kV breakdown), the pump must
be carefully inspected for leaks at
the shaft seal, conduit box, o-rings,
pipe plug and pressure valve,
before refilling with oil. To locate
the leak, perform a pressure test.
Oil Testing
ŸDrain oil into a clean, dry container
placing pump on it’s side, remove
cap screws (6), lift conduit box
assembly (4) from motor housing
(3). In separate container drain seal
chamber by removing pipe plug
(18).
ŸCheck oil for contamination using
an oil tester with a range to 30 kV
breakdown.
ŸIf oil is found to be clean and
uncontaminated (measuring
above 15 kV breakdown), refill the
housing.
Pressure builds up extremely
fast, increase pressure by
"TAPPING" air nozzle. Too
much pressure will damage
seal. DO NOT exceed 10 PSI
in housing and 20-25 PSI in
seal chamber.
Pressure Test
Motor Housing - Oil should be at
normal level. Remove pressure valve
(10) from motor housing (3). Apply
pipe sealant to pressure gauge
assembly and tighten into hole (See
Figure 2). Pressurize motor housing to
10 PSI.
DO NOT overfill oil.
Overfilling of housing with oil
can create excessive and
dangerous hydraulic pressure
which can destroy the pump
and create a hazard.
Overfilling oil voids warranty.

Risk of electric shock. Always disconnect the pump from the power source before handling inspections or repairs.
Symptom Possible Cause(s) Corrective Action
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 (go to manual
operation)
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 re-check current.
2a. Reposition pump or clean basin as required to
provide adaquate clearance for float
2b. Disconnect level control. Set ohmmeter for a
low rang, 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 re-check. If still defective, replace per
service instructions.
3. Make sure liquid level is above the pump
4. Re-check 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 cavity
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 flooded. 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 fixtures as required to eliminate leakage
12. Check pump temperature limits and fluid
temperature
13. Replace portion of discharge pipe with flexible
connector or tighten existing piping.
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 inflow or pump not properly sized for
application
9. Pump may be air locked causing pump not to flow
14. H-O-A switch on panel is in "HAND" position
Pump hums but doesn’t run
1. Incorrect low voltage
8. Impeller jammed or loose on shaft, or inlet
plugged
Pump delivers insufficient capacity
1. Incorrect low voltage
4. Excessive inflow or pump not properly sized for
application
5. Discharge restricted
6. Check valve partially closed or installed backwards
7. Shut-off valve closed
8. Impeller jammed or loose on shaft, or inlet
plugged
9. Pump may be air locked causing pump not to flow
10. Piping fixtures leaking or discharge before the
nozzle
Pump cycles too frequently or runs periodically
when f ixtures are not in use
6. Check valve partially closed or installed backwards
11. Fixtures are leaking
15. Ground water entering basin
Pump shuts of f and turns on independent of
switch, (trips thermal overload protector).
CAUTION! Pump may start unexpectedly.
Disconnect power supply.
1. Incorrect low voltage
4. Excessive inflow or pump not properly sized for
application
8. Impeller jammed or loose on shaft, or inlet
plugged
12. Excessive water temperature (internal
protection only)
Pump operates noisily or vibrates excessively
2c. Worn bearings, motor shaft bent
5. Debris in impeller cavity or broken impeller
10. Pump running backwards
13. Piping attachments to building structure too
loose or rigid
