Preventative Maintenance; Service And Repair - Barnes SFU SERIE Manual De Instalación Y Operaciones

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 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.
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
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 and clean the screen 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 7 and 8.
WARNING ! - Electrical power to the pump motor
must be disconnected and locked out to prevent
any dangerous electrical hazards or personnal
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 housing tube
(27) must be checked visually for oil level and contamination.
F-1.1) Checking Oil:
To check oil, set unit upright. Remove pipe plug (38). With
a fl ashlight, visually inspect the oil in the housing tube (27)
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 end, remove pipe plug (38) 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 (30), gland nut (13), O-rings (26),
diaphragm (15) and pipe plug (38) 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 housing tube and dispose of properly.
Refi ll with (see parts list for amount) new cooling oil as per
TABLE 2. An air space must remain in the top of the housing
tube when pump is placed with volute end on bench, to
compensate for oil expansion. Fill only until the capacitor, as
viewed through the fi ll plug hole is covered. When refi lling
with oil after servicing the shaft seal (30), 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 (38).
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,
O-rings, diaphragm 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.
Pressurize housing tube to 6 P.S.I. Use a soap solution
around the sealed areas and inspect joints for "air bubbles".
