Pressure Test (If oil has been
drained)
- Remove pipe plug (16)
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 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 (16) 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.
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
(16) then assemble to housing (4).

Disassembly and Assembly
Impeller, V-ring and Volute:
1. Disconnect power.

Service
Pressure builds up extremely
fast, increase pressure by
"TAPPING" air nozzle. Too
much pressure will damage
seal.
DO NOT exceed 10 PSI.
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.
To reassemble:
4. Clean the threads with thread
locking compound cleaner. Apply
removable Loctite® 242 or equivalent
to shaft threads.
2. Remove cap screws (8) and lock
washers (9) vertically lift motor,
housing and seal plate assembly from
volute (1). Clean out volute (1) if
necessary.
3. Inspect gasket (12) and replace if
cut or damaged.
4. Clean and examine impeller (2), for
cracks or breakage and replace if
required. To remove impeller (2),
remove impeller nut (10), place a flat
screwdriver in the slot of the end of
the shaft to hold the shaft stationary
while unscrewing the impeller (2).
Figure 2
5. Screw impeller (2) onto the shaft
hand tight while using a screwdriver
in the slot at the end of the shaft to
hold it stationary.
6. Install impeller nut (10) and
tighten. Rotate impeller to check for
binding.
7. Position gasket (12) on volute
flange and position impeller and
motor housing assembly on volute
(1).
8. Position lock washer (9) on cap
screw (8) and screw into volute (1).
Torque to 100 in-lbs. Check for free
rotation of impeller.
Motor, Capacitor and Bearings:
1. Place pump upright on blocks
or piece of PVC pipe, to avoid
resting unit on shaft.
2. Disassemble volute and
impeller as stated and drain oil
from housing.
3. Loosen gland nut (19) and slide
up cord along with washers (20)
and grommet (21).
4. Remove socket head screws (15)
from seal plate (3).
5. Slide motor housing (4) up
cable (18) until wire connectors
(24) are exposed.
NOTE wire
connections for reassembly.
6. Disconnect cable leads from
motor leads and remove motor
housing (4) and o-ring (11),
replace if cut or damaged.
