2. INSPECTIONS AND PREVENTIVE MAINTENANCE REQUIREMENTS
To assure satisfactory operation of the pump, daily inspections and periodic maintenance are required. We
suggest that an inspection and maintenance log be kept and that the inspector immediately report any
problems. A guide for preventive maintenance for normal applications is given below. Unusual applications,
with abnormal heat, moisture, dust, etc. may require more frequent inspections and service.

3. BEARING LUBRICATION
Grease Lubricated Bearings
Under normal operating conditions, the bearings must be lubricated after every 2000 hours of running
time, but at least once a year regardless of total operating hours.
CAUTION: ANY APPLICATION WITH ABNORMAL HEAT, MOISTURE, DUST, ETC. MAY
REQUIRE A CHANGE IN THIS SCHEDULE AND YOU SHOULD REFER TO A
LUBRICATION ENGIEER OR THE FACTORY FOR SPECIFIC INSTRUCTIONS.
CAUTION: THE GREASES RECOMMENDED IN THIS MANUAL WILL PROVIDE SATISFACTORY
LUBRICATION OVER A WIDE TEMPERATURE RANGE. THERE IS, HOWEVER, A
PRACTICAL LIMIT, AND OPERATION OF THE PUMP SHOULD BE DISCONTINUED
AND THE FACTORY CONSULTED IF THE TEMPERATURE, WHEN MEASURED ON
THE OUTSIDE OF THE BEARING HOUSING, EXCEEDS 190
o
F.
RECOMMENDED GREASE: Chevron SRI grease N.L.G.I. No. 2 multi-purpose with a mineral oil
viscosity of 517 SUS at 100
o
F or equivalent.
Proceed as follows for bearing lubrication:
WARNING: KEEP HANDS, FINGERS, CLOTHING AND ANY TOOLS AWAY FROM THE
COUPLING. FAILURE TO DO SO COULD RESULT IN SERIOUS PERSONAL
INJURY.
1. Stop the pump and remove the pipe plug at the bottom of the bearing housing.
2. Connect a grease gun to the lubrication fitting.
3. Inject grease until it relieves at the bearing housing cover and drain hole.
4. Remove the grease gun.
5. Start the pump. NOTE: Immediately after lubrication, bearing temperatures may rise above the
normal level. Continue running the unit until bearing temperatures stabilize at the normal level.
6. Stop the unit, wipe off the relieved grease and replace the drain plug.
7. Start the unit and resume normal operation.
