Pressure Test (If oil has been
drained) -
Remove pipe plug from
housing. Apply pipe sealant to
pressure gauge assembly and tighten
into hole. Pressurize motor housing
to 10 PSI. Use soap solution around
the sealed areas and inspect joints
for "air bubbles".
After leak is repaired, dispose of old
oil properly, and re ill with new oil.
f
Oil Replacement -
Set unit upright
and refill with new cooling oil as per
table below . Fill to just above motor,
but below capacitor as an air space
must remain in the top of the housing
to compensate for oil expansion.
Apply pipe thread compound to
threads of pipe plug then assemble
to housing.
Oil Testing
Ÿ
Drain oil into a clean, dry container
by placing pump on it’s side,
remove pipe plug (20), from
housing (10).
Ÿ
Check oil for contamination using
an oil tester with a range to 30
kV
breakdown.
Ÿ
If oil is found to be clean and
uncontaminated
(measuring
above 15 V breakdown), re ill the
k
f
housing.
Ÿ
If oil is found to be dirty or
contaminated (or measures below
15 breakdown), the pump must
kV
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
f
the leak, perform a pressure test.
Pressure builds up extremely
fast, increase pressure by
"TAPPING" air nozzle. Too
much pressure will damage
seal.
DO NOT exceed 10 PSI.
Pressure Test (If oil has NOT been
drained) -
Oil should be at normal
level. Remove pipe plug from
housing. Apply pipe sealant to
pressure gauge assembly and tighten
into hole. Pressurize motor housing to
10 PSI. Use soap solution around the
sealed areas above the oil level and
inspect joints for "air bubbles". For
sealed areas below oil level, leeks will
seep oil. If, after five 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.
DO
NOT
overfill
oil.
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.

Cooling Oil -
Anytime the pump is
removed from operation, the cooling
oil in the motor housing should be
checked visually for oil level and
contamination. To check oil, set unit
upright. Remove pipe plug from
housing. With a flashlight, visually
inspect the oil in the housing 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.
Servicing
If, after five minutes, the pressure is
still holding constant, and no
"bubbles" are observed, slowly bleed
the pressure and remove the gauge
assembly. Replace oil. Leek must be
located and repaired if pressure does
not hold.
Disassembly & Assembly
Impeller U-cup, V-ring and Volute:
Disconnect power. Remove cap
screws and lock washers vertically lift
motor, housing and seal plate
assembly from volute. Clean out
volute if necessary. Inspect gasket
and replace if cut or damaged. Check
U-cup for damage. If replacement is
needed, cut the U-cup from the
volute and clean surface of bore.
Clean and examine impeller, for
cracks or breakage and replace if
required. To remove impeller, place a
flat screwdriver in the slot of the end
of the shaft to hold the shaft
stationary while unscrewing the
impeller.
