a) Pump supports are firmly in place.
b)
Pump covers over openings are firmly in place.
Pump coverings, plastics or tarps, are firmly in place. Any holes or tears must be repaired to prevent entrance of
dirt or water.
c)
Pump covers are periodically removed from openings and interior accessible areas inspected. If surface
rusting has occurred, clean and repaint or re-coat with preservative.
d)
If rusting occurs on exterior surfaces, clean and repaint or re-coat with preservative.
e)
Loosen casing drain plugs to allow seepage of any accumulated moisture.
f)
If the rotor is stored horizontally, rotate pump rotor 1-1/4 revolutions at least once a month to prevent
rotor from taking a permanent set.
Caution
Make sure bearings have adequate lubrication before turning rotor.
The oil inlet blanking plates should be removed and a small amount of oil injected
into the bearings before turning. Refit blanking plates.
g)
Periodically remove bearing covers and inspect for accumulation of moisture, rust and foreign material.
As required, clean bearings and bearing housing and re-preserve. Install bearing cover and secure to
assure maximum protection. Bearings removed for storage should be coated with preservative, wrapped
in oil/wax paper, and stored in a warm dry area.
h)
Check individually wrapped parts for signs of deterioration. If necessary, renew preservative and
wrapping.
Caution
If storage is over one month, Instrumentation (Controls, Electrical devices,
Temperature switches) should be removed and placed in a climate control
environment if Instrumentation is not powered up.
2.4.4 Storage non-preferred (wet)
It is not recommended that the rotor be subjected to extended periods of submergence or wetting prior to start-
up. However, it is recognized that in some cases, a long period of time may lapse from installation until
commercial operation.
If the pump must be stored after being installed and wetted, the following inspection and maintenance should be
performed.
Isolate the pump with valving - tag (seal) all valves.
Preserve the pump internals.
NOTE
If storage is over one month, Instrumentation (Controls, Electrical devices,
Temperature switches) should be removed and placed in a climate controlled
environment if Instrumentation is not powered up.
Caution
Electric motors (pump driver) should not be stored in damp places without special
protection (refer to motor manufacturer’s instructions).
