Requirements
Keep the following points in mind when lubricating with grease:
• Grease must be of sodium or lithium base with a NLGI-2 consistency. Do not use graphite.
• Greases made from animal or vegetable oils are not recommended due to the danger of deteriora-
tion and forming of acid.
• Additional or replacement lubricant must be added after 2,000 hours or at three-month intervals.
• Replace the lubricant in the housings at least once annually. This must be done when an overhaul
is made.
• When greasing anti-friction bearings, do not use high-pressure equipment. High pressure can dam-
age the bearings or seals, cause unnecessary loss of grease, create a danger of overheating due
to over greasing, and produce unsightly conditions around the bearing.
• Excess grease is the most common cause of overheating. Maintain the grease level at about the
capacity of the bearing and 1/3 to 1/2 of the cavity between the bearing and grease fitting. Any
greater amount will be discharged by the seal or vent.
6.3.2 Lubricate the oil-lubricated bearings
Oil-lubricated ball bearings are optional. Oil-lubricated pumps are supplied with oilers that maintain a
constant oil level in the bearing housing.
For an illustration of the oiler, see 5.8.2 Lubricate the bearings with oil (optional) on page 44 .
1. After the pump has been installed, flush the housings to remove dirt, grit, and other impurities that
have entered the bearing housing during shipment or installation.
2. Fill the oiler bottles on both bearing housings with the proper lubricant and place on the oiler hous-
ing.
The oil reservoir in the bearing housing is filled when a constant oil level remains in the bottle. Sev-
eral fillings of the bottle are required for initial lubrication. Never put oil into the oiler housing without
the use of the oiler bottle.
6.3.2.1 Lubricating-oil requirements
Oil requirements based on temperature
For the majority of operating conditions, bearing temperatures run between 49°C | 120°F and 82°C | 180°F,
and you can use an oil of ISO viscosity grade 68 at 38°C | 100°F. If temperatures exceed 82°C | 180°F, refer to
the table for temperature requirements.
Temperature Oil requirement
Bearing temperatures exceed 82°C |
180°F Use ISO viscosity grade 100. Bearing temperatures are generally about 11°C
| 20°F higher than bearing-housing outer surface temperatures.
Pumped-fluid temperatures are ex-
treme Refer to the factory or a lubrication expert.
