Goulds Pumps CV 3171 - IOM - Manual (Page 27)

CV 3171 IOM 05/11 27
The original grease from the factory is a lithium
based NLGI 2. Table 2 lists some various
manufacturers compatible greases.
Temperature extremes (either high or low) may
require a different grease.
NOTE: If it is necessary to change the grease
type or consistency, the bearing must be
removed and all the old grease eliminated from
the housing and bearing.
Bearings must be lubricated properly
in order to prevent excess heat
generation, sparks and premature
failure.
Throughout this section on bearing
lubrication,
different pumpage
temperatures are listed. If the
equipment is ATEX certified and the listed
temperature exceeds the applicable value
shown in Table 1 under ATEX identification,
then that temperature is not valid. Should this
situation occur, please consult with your ITT
Goulds representative.
