8.1 Maintaining the product

8.1.1 Lubricating the motor
DANGER
Moving machine parts
Death or serious personal injury
- Before any inspection, maintenance, service or
repair of the product, make sure that the motor
controls are in the "OFF" position, locked and
tagged.
Always follow the motor manufacturer's lubricating instructions, if
they are available, and periodically check grease fittings and
drain plugs for leaks. If the lubricating instructions are not
available, refer to the table below for recommended lubricating
intervals.
• The motor can be lubricated both when it is running or when it
is at rest.
Remove the grease drain plug (if any) and filler plug on the
grease fitting. Grease with clean lubricant until grease
appears at the drain hole or along the motor shaft.

8.1.2 Lubricating the pump bearings

WARNING
Catastrophic failure
Death or serious personal injury
- Maintain proper lubrication schedule
- Do not operate the unit without proper lubrication
as this can result in overheating of the bearings,
bearing failures, pump seizures and actual
breakup of the equipment, exposing operating
personnel to personal injury.

Regreasable bearings are packed with grease at our factory prior
to shipping. This initial filling of grease is good for one year or
2000 hours of normal operation, whichever occurs first. After one
year or 2000 hours of normal operation, a regular grease
maintenance schedule must be implemented.

8.1.3 Grease replacement (KP, KPV)

1. Remove the four (4) cap screws and remove the bearing
covers (113C and 113D) to allow access to the bearing.
2. Use a clean rag to remove as much old grease as possible
from the bearing.
3. Re-pack the bearing with sufficient grease to completely fill
and cover the balls inside the bearing.
4. Turn the pump shaft to ensure even and complete lubrication.
5. For drive end bearing maintenance, slide the bearing cover
back as far as possible and visually inspect bearing for
grease.
6. Proceed as stated above removing old grease with a clean
rag. If the bearing covers cannot be moved sufficiently to
allow access to bearing, remove the coupling hub.
7. Reinstall the bearing covers when the task is complete.
Do not over-grease. Too much grease can cause
overheating and premature bearing failure.
Bearing manufacturers recommend that you fill the bottom third of
the bearing with grease. After filling the bottom third with grease,
rotate the shaft to cover the balls inside the bearing.
