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".

Service
After leak is repaired, dispose of old
oil properly, and refill with new oil.
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.
Figure 4
Pressure builds up extremely
fast, increase pressure by
"TAPPING" air nozzle. Too
much pressure will damage
seal.
DO NOT exceed 10 PSI.
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
(20) then assemble to housing (4).
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.

Disassembly
Impeller, V-ring and Volute:
1. Disconnect power.
2.
Remove
capscrews
and
lockwashers, vertically lift motor
housing and seal plate assembly from
volute. Clean out volute if necessary.
3. Inspect gasket and replace if cut or
damaged.
4. 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.
5. Check v-ring and remove if
damaged.
Power Cord and Motor:
6. Remove pipe plug and drain oil
from housing.
7. Remove gland nut, washer and
ring from housing. Pull cord through
and disconnect the wires from the
terminals on power cord.
8. Remove screws and lift motor
housing and stator from seal plate.
Ÿ
If oil is found to be clean and
uncontaminated
(measuring
above 15 kV breakdown), refill
the housing.
Ÿ
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, cable assembly, square ring
and pipe plug, before refilling
with oil. To locate the leak,
perform a pressure test.
Pressure Test (If oil has NOT been
drained)
- Oil should be at normal
level. Remove pipe plug (20) from
housing (4). 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.
10. Check motor capacitor with an
Ohm meter by first grounding the
capacitor by placing a screwdriver
across both terminals and then
removing screwdriver. Connect Ohm
meter (set on high scale) to terminals.
If needle moves to infinity (∞) then
drifts back, the capacitor is good. If
needle does not move or moves to
infinity (∞) and does not drift back,
replace capacitor.
9. Remove v-ring, replace if damaged.
