GENERAL COMMENTS
LUBRICATION
The ball bearing (112) supplied is greased for life. No
further lubrication is required. Column bearings (197B)
must be lubricated by an integral pumpage flush or clean
source of external liquid flush. Consult ITT Goulds
Pumps for appropriate option. Follow motor and
coupling manufacturers lubrication instructions.
MAINTENANCE
1. Periodically lubricate the upper ball bearing(s) when
equipped with grease fittings.
2. Check for noise (mechanical or hydraulic) and
vibration.
3. Check float switch operation.
4. Check flush line to the line shaft bearings for
buildup.
5. Check discharge pressure gauge periodically.
VIBRATION
It is good practice to periodically monitor vibration of the
pump. Normally, vibration level will be well below
accepted standards. Of equal importance is that the
vibration level not increase. If a problem with vibration is
encountered, refer to Troubleshooting in the Disassembly
& Reassembly Section.
