ANNUAL INSPECTIONS

Check the pump capacity, pressure and power. If
pump performance does not satisfy your process
requirements, and the process requirements have
not changed, the pump should be disassembled,
inspected, and worn parts should be replaced.
Otherwise, a system inspection should be done.

INSPECTION INTERVALS

Inspection intervals should be shortened appropriately
if the pumpage is abrasive and/or corrosive,

!

or if the environment is classified as
potentially explosive.

MAINTENANCE OF BEARINGS

!

Throughout this section on bearing lubricat-
ion, 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. When this
situation occurs please consult with your ITT
Goulds representative.

OIL LUBRICATED BEARINGS

!

WARNING

Pumps are shipped without oil. Oil lubricated
bearings must be lubricated at the job site.

Remove fill plug (113A) and add oil until level is at the
center of the sight glass (319). Replace fill plug
(Fig. 34) (See Table 4).

Change the oil after 200 hours for new bearings,
thereafter every 2000 operating hours or 3 months
(whichever comes first).

A high quality turbine oil with rust and oxidation
inhibitors should be used. For the majority of
operational conditions, bearing temperatures will run
between 120°F (50°C) and 180°F (82°C). In this
range, an oil of ISO viscosity grade 68 at 100°F
(40°C) is recommended. If bearing temperatures
exceed 180°F (82°C), use ISO viscosity grade 100
with Bearing Frame cooling or Finned Tube oil cooler.
The Finned Tube oil cooler is standard with the model
HT 3196 and optional for all other models (See
Table 5). For higher operating temperatures,
pumpage above 350°F (177°C), synthetic lubrication
is recommended.
