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). “Rota-
tion” 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:

Include 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 it’s 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.

WARNING ! - Electrical power to the pump
motor must be disconnected and locked out
to prevent any dangerous electrical hazards or
personnel danger before any service work is
done to the pump

CAUTION: - Operating pump builds up heat
and pressure; Allow time for pump to cool
to room temperature before handling or
servicing

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
