Lubrication Instructions
Oil Lubricated Frame Pumps
If frame is grease lubricated, see “Lubrication Instructions – Grease Lubricated Frame Pumps,” page 3200-901.
The ball bearings are lubricated by the oil in the frame housing.
Add oil through the pipe plug opening at the top of the housing and fill to the level indicated on the side of the
housing. Be careful to keep out dirt and moisture. The oil level must be maintained; check and fill when pump
is not operating. The type and grade of oil used is very important for maintenance-free operation.
Oil used should be a turbine oil equivalent to one of the following manufacturer’s products:
Oil Temperature to 150
0
F Oil Temperature Over 150
0
F
ISO VG32
Mobil DTE 797
Lubriplate HO-0
Chevron Turbine Oil GST 32
Shell Turbo T Oil 32
ISO VG68
Mobil DTE Oil Heavy Medium
Lubriplate HO-2
Chevron Turbine Oil GST 68
Shell Turbo T Oil 68
If checking oil temperature is not feasible, measure the bearing frame temperature at the drain connection.
In general, the bearing frame temperature will be approximately 10
0
F lower than the oil temperature.
Oil recommendation is based on a minimum of 70 SSU at operating temperature.

F5K 1 QUART 3-4 MONTHS
F85K/85DBK 1.5 QUARTS 3-4 MONTHS
F13K/13DBK 1.5 QUARTS 3-4 MONTHS
F16K 2 QUARTS 5-6 MONTHS
F18K/18DBK 3 QUARTS 5-6 MONTHS
F12K 4 QUARTS 5-6 MONTHS
F24DBK 8 QUARTS 5-6 MONTHS
F20DBK/TBK 9 QUARTS 5-6 MONTHS
Lip Seals (grease)
All oil-filled frames will have lip seals in their bearing covers. All lip seals must be lubricated through the
grease fittings placed in the bearing cover at either end of the frame. Lubricate with a small amount of
multiple-purpose grease after every two to six months, depending upon environment.
