6.0 Lubrication of the Power End
6.1 Recommended Lubricants
Few factors can influence the life of a pump more than the power end lubricant (oil).
Careful selection of the right type of oil for each particular application will help ensure
optimal performance and longevity from an FMC pump.
The intent of this section is to state the general lubrication requirements for FMC
pumps. Several products are listed by manufacturer name in the table below in order to
aid the customer in locating suitable lubricants. The following listing is not exclusive,
and it is not an endorsement of any particular product or manufacturer. Consult FMC for
lubrication recommendations for applications that fall outside of the conditions listed in
Table 2 below.
Lubricant temperatures should not exceed 170° F (77° C) for continuous
duty or 180° F (82° C) for intermittent duty applications on W11 pumps.
Crankcase temperatures that exceed these limits will cause the mineral
based lubricant to prematurely "break-down." The result will be poor
lubrication and failure of power end components.
6.2 Oil Changes
Oil changes must be carried out after first 100 hours of operation, and
subsequently every 4000 hours or 6 months, whichever comes first. These
intervals may be modified depending on actual operating conditions.
Oil should be changed when hot to prevent build up of sludge deposits.
It is advisable to check oil level daily. If more than 10% of the total capacity has to
be added, check for oil leaks.
Do not mix oils of different types, even if produced by the same manufacturer.
Never mix mineral and synthetic oils.
To avoid the risk of scalding or burns, pay attention to oil and power end
temperature during an oil change.
Follow environmental guidelines when changing and disposing of lubricants.
