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 cap screws (6), lift
conduit box assembly (4) from motor
housing (3),
Do Not
disconnect
wiring from motor leads. With a
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 considerable
water or other contamination, the
shaft seal (19) should be inspected
and replaced if required.
After leak is repaired, dispose of old
oil properly, and refill with new oil.
Use soap solution around the sealed
areas above the oil level and inspect
joints for "air bubbles". 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.
Seal Chamber -
Check that seal
chamber is full of oil by removing
pipe plug (18). Apply pipe sealant to
pressure gauge assembly and tighten
into hole in bearing housing (16).
Pressurize seal chamber to 20-25 PSI
and check for leaks.
Oil Replacement
- Set unit upright
and refill with new cooling oil as per
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.
Oil Replacement:
Seal Chamber -
Refill chamber
completely full with new cooling oil
or reuse the uncontaminated oil.
NOTE: Item numbers in ( ) refer to
Figures 6.
Servicing
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, conduit box, o-rings,
pipe plug and pressure valve,
before refilling with oil. To locate
the leak, perform a pressure test.
Oil Testing
Ÿ
Drain oil into a clean, dry container
placing pump on it’s side, remove
cap screws (6), lift conduit box
assembly (4) from motor housing
(3). In separate container drain seal
chamber by removing pipe plug
(18).
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 kV breakdown), refill the
housing.
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.
Pressure Test
Motor Housing -
Oil should be at
normal level. Remove pressure valve
(10) from motor housing (3). Apply
pipe sealant to pressure gauge
assembly and tighten into hole (See
Figure 2). Pressurize motor housing to
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.
