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.) Identifi cation Plate:
Record future serial plate information in the “NOTES” section.
D-3.1) 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 along with the volume of water, should be
recorded on the start-up report.
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 failing. In our experience attempts
at preventative maintenance are more likely to reduce, rather
than extend the life of our pumps. However, if you are inclined
to perform preventative maintenance, the following are the
steps that should be performed.
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 motor and bearings 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 in ( ) refer to Figures 15 thru 18
CAUTION ! - Operating pump builds up heat and
pressure; allow time for pump to cool to room
temperature before handling or servicing. Slowly
remove pipe plug prior to servicing as housing
may be pressurized.
F-1) Lubrication:
Anytime the pump is removed from operation, the cooling oil in
the motor housing (6) should be checked visually for oil level
and contamination.
F-1.1) Checking Oil:
Motor Housing-
To check oil, set unit upright. Remove pipe
plug (39) from housing (6). With a fl ashlight, visually inspect the
oil in the motor housing (6) 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.
F-1.2) Testing Oil:
1.) Place pump on it’s side, remove pipe plug (39), from motor
housing (6) 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 (measuring
above 15 KV. breakdown), refi ll the motor housing as per
section F-1.4.
4.) If 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 (28), cable assemblies
(16) and (56 if used), square ring (27) and pipe plug (39),
before refi lling with oil. To locate the leak, perform a
pressure test as per section F-1.3. After leak is repaired,
dispose of old oil properly, and refi ll with new oil
as per section F-1.4.
F-1.3) Pressure Test:
Pumps that have had the oil drained from the Motor Housing
-
Apply pipe sealant to pressure gauge assembly and tighten
into pipe plug hole (See Figure 3). Pressurize motor housing to
10 P.S.I. Use 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 oil as described in section F-1.4.
If the pressure does not hold, then the leak must be located and
repaired.
Pumps that have NOT had the oil drained from the Motor
Housing
- The pressure test may be done with the oil at its
normal level. Remove pipe plug (39) from motor housing (6).
Apply pipe sealant to pressure gauge assembly and tighten into
hole (see Figure 3). Pressurize motor housing to 10 P.S.I. Use
soap solution around the sealed areas above the oil level and
inspect joints for “air bubbles”. For sealed areas below the oil
level, leaks will seep oil.
