PREVENTIVE MAINTENANCE
LUBRICATION
The ball bearing (112) supplied is greased for life.
No further lubrication is required. Column bearings
(213) must be lubricated by an integral pumpage
flush or clean source of external liquid flush.
Consult Goulds Pumps for appropriate option.
Follow motor and coupling manufacturers lubrication
instructions.
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 Trouble Shooting
(page 20).
