Oil Testing
• Drain oil into a clean, dry container by
placing pump on it’s side, remove pipe
plug, from housing.
• Check oil for contamination using an
oil tester with a range to 30 Kilovolts
breakdown.
• If oil is found to be clean and
uncontaminated (measuring above
15 KV. breakdown), refill 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, cable assembly, square ring,
o-ring and pipe plug, before refilling with
oil. To locate the leak, perform a pressure
test.
After leak is repaired, dispose of old oil
properly, and refill with new oil.
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 P.S.I. Use soap solution
around the sealed areas and inspect joints
for “air bubbles”.
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.
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 P.S.I. 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.
Pressure builds up extremely
fast, increase pressure by
“TAPPING” air nozzle. Too much
pressure will damage seal.
DO
NOT exceed 10 P.S.I.
Oil Replacement
- Set unit upright and
refill with new cooling oil as per table. 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.
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 legs (33) and remove strainer
(32).
3. Remove cap screw (27) and washers
(28) vertically lift motor, housing and seal
plate assembly from volute (1). Clean out
volute (1) if necessary.
4. Inspect gasket (2) and replace if cut or
damaged.
5. Clean and examine impeller (31), for
cracks or breakage and replace if required.
To remove impeller (31), place a flat
screwdriver in the slot of the end of the
shaft to hold the shaft stationary while
unscrewing the impeller (31).
6. Check v-ring (29) and remove if
damaged.
Power Cord & Motor:
7. Remove pipe plug (16) and drain oil
from housing.
8. Remove gland nut (15E), from upper
motor housing (17). Remove capscrews
(21) and washers (22) and lift off upper
motor housing (17) and o-ring (9). Pull
cord through and disconnect the wires
from the terminals on power cord (15).
9. Remove screws (4) and lift motor
housing and motor from seal plate (8).
