Goulds Pumps 3420 - IOM - Manual (Page 31)

Grease Lubrication: Pumps are shipped with grease
installed, sufficient for 2,000 hours operation. It is
recommended that additional or replacement lubrication be
added after every 2,000 hours or at three month intervals.
The lubricant should be renewed in the housings at least
once each year. See Table 5 (p. 35) for recommended
greases.
If the pump is put into operation after a prolonged
shut-down, flush out the bearing housings with a light oil
to remove any contaminants. During flushing, rotate the
shaft slowly by hand. Finally, flush the bearing housing
with the proper lubricating oil to ensure oil quality after
cleaning.
s
! WARNING
Operation of the unit without proper lubrication will
cause bearing failure and pump seizure.
SHAFT SEALING
!
Packed stuffing boxes are not allowed in an ATEX
classified environment.
Packed Stuffing Box: Pumps are shipped without packing,
lantern ring, or split gland installed. These are included in
the box of fittings shipped with the pump and must be
installed before start-up.
Installation of Packing:
1. Carefully clean the stuffing box bore.
2. Twist the packing just enough to get it around the
shaft (Fig 15).
3. Insert packing, staggering the joints in each ring by
90° degrees.
