Oil Fill - PENTA HYDROMATIC SK60 Series Installation And Operator's Manual

Maintenance
4. remove the old seal ring (18) and stretch on new
ring with o-ring lube.
do not roll the ring onto seal plate or water leakage
into the motor housing will result.
5. Fasten the ground wire inside the motor housing and
tuck wires up into the housing to prevent rubbing on
the rotor; then assemble housing (19) to volute (12)
with bolts (17).
6. Before filling the motor housing with oil, a seal leak
test should be performed. apply 7 to 8 pounds of air
pressure in the 1/4" NPT tap (21) on the top of the
motor cover and seal chamber.
NOTICE Too much pressure will damage the seal.
Seal would have to be replaced.
Then submerge the pump in water and check for
leaks. If a leak occurs, isolate where it is coming
from and correct the problem by replacing the
failed part.
HYdromaTIc pumps have a small air vent hole in
the impeller cavity to let out trapped air. If this hole
becomes plugged, pump may air lock. To break the
air lock, use a small screwdriver to clear hole in the
impeller cavity.
as a secondary precaution in installations of this
type, an 1⁄8" hole should be drilled in the discharge
pipe just above the volute. The check valve should
be at least 12 inches above pump discharge and
mounted horizontally. do not put check valve
directly into pump discharge opening.
NOTICE: In sumps where the pump is operating
daily, air locking rarely occurs.

Oil fill

1. after seal leak test is satisfactory, remove unit from
water and wipe or blow off any excess water.
2. do not put oil in motor with any water present in
motor cavity.
3. Use refined paraffinic transformer oil,
2210 or equivalent.

4. Slowly fill oil to 1/8" over windings in motor housing
through opening (21). Use an oil fill tube that will go
into holes so that air can escape. replace plug (21).
NOTICE do not fill the motor housing completely –
allow air space for expansion.
5. connect power cord wires to terminals in panel, or
connect power source, and check pump running.
motor should run smoothly and be free of vibration.
Pump is ready for operation.
