SECTION: D START-UP OPERATION
D-1) Check Voltage and Phase:
Before operating pump, compare the voltage and phase
information stamped on the pump identification plate to the
available power.
D-2) Check Pump Rotation:
Before putting pump into service for the first 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 motor housing.
D-2.1) Incorrect Rotation for Three-Phase Pumps:
In the event that the rotation is incorrect for a three-phase
installation, interchange any two power cable leads at the
control box. DO NOT change leads in the cable housing in the
motor. Recheck the "kickback" rotation again by momentarily
applying power.
D-2.2) Incorrect Rotation for Single-Phase Pumps:
In the unlikely event that the rotation is incorrect for a single
phase pump, contact a Barnes Service Center.
D-3) Start-Up Report:
Included at the end of this manual is a start-up report sheet,
this sheet is to be completed as applicable. Return one copy
to Barnes 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 refer
to should servicing the pump be required in the future.
D-3.1) Identification Plate:
Record the numbers from the pump identification plate on both
START-UP REPORTS provided at the end of the manual for
future reference.
D-3.2) Insulation Test:
Before the pump is put into service, an insulation (megger)
test should be performed on the motor. The resistance values
(ohms) as well as the voltage (volts) and current (amps) should
be recorded on the start-up report.
D-3.3) 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 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 on the start-up report.
SECTION E: PREVENTATIVE MAINTENANCE
As the motor is oil filled, 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 failing. However as with any
mechanical piece of equipment a preventive maintenance
program is recommended and suggested to include the
following checks:
1) Inspect motor and seal chambers 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 motor and bearings and replace as required per
section F-3.
4) Inspect seal and diaphragm for wear or leakage and repair
as required per section F-4.

SECTION F: SERVICE AND REPAIR
NOTE: All item numbers in ( ) refer to Figures 9 & 10,
3450RPM and Figures 11 & 12 , 1750RPM.
F-1) Lubrication:
Anytime the pump is removed from operation the cooling oil
in the motor housing (2) and seal chamber, must be checked
visually for oil level and contamination.
F-1.1) Checking Oil:
Motor Housing - To check oil, set unit upright. Remove cap
screws (6) and lockwashers (4), lift conduit box assembly (9)
from motor housing (2) but DO NOT disconnect conduit box
wiring from motor leads. With a flashlight, visually inspect the
oil in the motor housing (2) to make sure it is clean, clear and
that oil level is above all internal componentry.
Seal Chamber - Place pump on its side with the square
head pipe cap (22) downward, remove pipe cap (22) and
drain oil from the seal chamber. If the oil is found to contain
considerable water or other contamination or little oil drains
out, the shaft seal (38) and diaphragm (31) should be
inspected and replaced if required.
F-1.2) Testing Oil:

3.
4.
F-1.3) Replacing Oil:
Motor Housing - Drain all oil from motor housing and
dispose of properly. Refill with (see parts list for amount) new
cooling oil as per Table 1. An air space must remain in the top
of the motor housing to compensate for oil expansion (see
Fig. 9 or 11). Set unit upright and fill only until the motor, as
viewed through the conduit box opening, is just covered and
no more. Reassemble the O-ring (10), conduit box assembly
(9), cap screws (6) and lockwashers (4), apply Locktite (47)
to each cap screw (6) thread before installing. Torque cap
screws (6) to 17.5 ft, lb.
Seal Chamber - Refill chamber completely full with new
cooling oil per Table 1 or reuse the uncontaminated oil.

Place pump on it's side, remove cap screws (6) and
lockwashers (4), lift conduit box assembly (9) from
motor housing (2) and drain oil into a clean, dry container.
In separate container drain seal chamber by removing
pipe cap (22).
Check oil for contamination using an oil tester with a
range to 30 Kilovolts breakdown.
If oil is found to be clean and uncontaminated (measure
above 15 KV. breakdown), refill the motor housing and
seal chamber as per section F-1.3.
If oil is found to be dirty or contaminated (or measures
below 15 KV. breakdown), the the pump must be carefully
inspected for leaks at the shaft seal (38), conduit box
assembly (9), diaphragm (31), O-rings (10) and (36),
pipe cap (22) and pipe plug (5) before refilling with oil.
To locate the leak, perform a pressure test as per
section F-1.4.
After leak is repaired, refill with new oil as per section
F-1.3.
Important ! - DO NOT overfill oil.
Overfilling of motor housing with oil can
create excessive and dangerous hydraulic
pressure which can destroy the pump
and create a hazard. Overfilling oil voids
warranty.
