Goulds Pumps 3410 - IOM - Manual (Page 39)

LUBRICATION
!
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 SAFETY, then that temperature is not
valid. Should this situation occur, please consult
with your ITT/Goulds representative.
GREASE LUBRICATION
Grease lubricated ball bearings are standard on all Model 3410
pumps. These units can be identified by grease fittings located on
the bearing housing.
• Grease should be of sodium or lithium base, NLGI #2
consistency. DO NOT USE GRAPHITE.
• It is suggested that additional or replacement lubricant
be added after 2,000 hours or at three-month intervals.
• Lubricant should be renewed in housings at least once
annually. This should be done when an overhaul is
made.
• To grease bearings, proceed as follows:

CAUTION
Grease lubricated bearings are lubricated at the
factory. Do not grease at too frequent intervals.
1. Remove relief plug (1) on bearing housing. See Fig.
33.
2. Insert grease through fitting (2) until grease appears
through relief plug hole.
3. Repeat steps 1 and 2 on other bearing.
4. Operate unit approximately 1/2 hour with relief holes
open to prevent overgreasing. After 1/2 hour, replace
relief plugs on both bearing housings.
OIL LUBRICATION
Flood oil lubricated ball bearings are optional on all Model
3410 units. Oil lubricated pumps are supplied with oilers
which maintain a constant oil level in the bearing housing.
$
CAUTION
Under normal operating conditions, an oil of 300 SSU
viscosity at 100°F (38°C) (approximately SAE-20)
should be used, (see lubricant recommendations
below). For extreme conditions refer to the factory or a
lubrication expert for a recommendation.
Fill auto oiler bottles on both bearing housings with the
proper grade of oil and place on oiler housing. Oil reservoir
in bearing housing is filled when a constant oil level
remains in the bottle. Several fillings of bottle are required
for initial lubrication. Never fill through the oiler housing
without use of the oiler bottle.
