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 ousing should be
h
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),
wiring from motor leads. With a
barmesa.com
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 c onsiderable water
or other contamination, the shaft seal
(19)
should
be
replaced if required.

Pressure Test
s
Motor Housing - Oil should be at
r
normal level. Remove pressure valve
(1 ) from motor housing (3). Apply
1
pipe sealant to pressure gauge
assembly and tighten into hole (See
Figure 2). Pressurize motor housing to
10 PSI.
If oil is found to be clean and
uncontaminated
(measuring
above 15 V breakdown), re ill
k
the housing.
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, conduit box, o-rings, pipe
plug and pressure valve, before
re illing with oil. To locate the
f
leak, perform a pressure test.

Figure 2
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.
Use soap solution around the sealed
areas above the oil level and nspect
f
joints for "air bubbles". If, after ive
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
c hamber is full of oil by removing
pipe plug (18). Apply pipe sealant to
p ressure gauge assembly and tighten
into hole in bearing housing (1 ). 5
P ressurize seal chamber to 20-25 PSI
and check for leaks.
Oil Replacement - Set unit upright
and re ill with new cooling oil as per
f
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.
DO
NOT
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.
Oil Replacement:
Seal Chamber - Refill chamber
c ompletely full with new cooling oil
or reuse the uncontaminated oil.
