3 Month Inspections
,f@--
l Check shaft alignment and realign if required.
l Check foundation and hold-down bolts for tightness.
l If pump has been left idle, check packing. Replace
if required.
l Oil should be changed at least every 3 months
(2000 hours) or more often if there are any adverse
atmospheric conditions or other conditions which
might contaminate or break down the oil, or if it is
cloudy or contaminated as seen by inspection
Annual Inspections
l Check pump capacity, pressure and Dower. If
pump perfoLnance does not satisfy iour process
requirements, and process requirements have not
changed, pump should be disassembled,
inspected, and worn parts should be replaced,
otherwise, a system inspection should be done.

MAINTENANCE OF BEARINGS

01~ LUBRICATED Bows
.
Pumps are shipped wlthout oil. Oil lubricated
bearings must be lubricated at the job site.

Remove fill plug (408H) and add oil until letiel is at the
center of the sight glass (319). Replace fill plug
(Fig. 18A). See Table 4.
Fig. 18A
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%) and 18O’F (82%). In this
range, an oil of IS0 viscosity grade 68 at 1 OO’F
(40%) is recommended. If bearing temperatures
exceed 18O’F (82%) use IS0 viscosity grade 100
with Bearing Frame cooling. See Table 5, For higher
operating temperatures, pumpage above 350°F
(1 i7’C), synthetic lubrication is recommended.
