Goulds Pumps 3498 - IOM - Manual (Page 22)

Indoor Storage
Little extra preparation is needed if indoor storage area is
dry and clean. Care should be taken to prevent extremes in
temperature (below 32°F and above 110°F). Also, keep the
pump out of direct sunlight and covered to protect it from
dust and dirt. Care should be taken to prevent moisture
build-up around the pump, either by allowing proper
ventilation or tightly sealing the pump in the cover with a
suitable amount of desiccant to ensure dryness.
If indoor storage area is humid or dirty, such as an
unfinished building, treat the pump as if it were to be stored
outdoors.
Outdoor Storage
Pump should be covered to protect it from weather and
direct sunlight. All coverings should be properly secured to
withstand high wind. Care must be exercised in covering
pumps to prevent moisture build-up under the cover. This
can be done either by allowing proper ventilation or tightly
sealing cover with suitable amount of desiccant to ensure
dryness.
Extreme heat and cold are to be avoided, as rubber parts
and seals could age prematurely (below 32°F and above
110°F).
Installed but Not in Service
Preparation for storage under these conditions is the same
as for indoor and outdoor, except the suction and discharge
piping will serve as flange covers.
The suction and discharge valves must be tightly closed
and all water removed from the pump and attached piping.
The Interior of the pump and piping must be thoroughly
dried.
Preparation procedures should be repeated every 12
months.
Maintenance
Indoor
The only maintenance required will be to rotate the pump
shaft 10-15 times twice a month. This operation is to recoat
the bearings with grease or oil and to prevent false
brinelling. Be sure the shaft comes to rest in different
positions.
Outdoor
Storage area should be inspected weekly, and after storms,
for damage to protective covers. Shafts should be rotated
10-15 turns three times a month.
Preparation procedure should be repeated every six months
for normal environments, and every two months for
corrosive environments (such as salt air).
Installed, But Not In Service
Follow same procedures as for indoor storage, except
inspect the casing area once a month for moisture build-up,
replacing volatile corrosion inhibitor at that time.
Preparation for Operation
1.
Remove all rust inhibitor from exposed machined
surfaces using the method described by the supplier.
2. Remove all corrosion protection devices or material
from pump casing.
3. If the pump has packing, repack pump using the
method described in the instruction book.
4. If the pump has mechanical seals, drain protective oil
from seal cavity. Flush cavity with clean water or seal
lubricant for five minutes before start-up.
5. Remove flange covers, tape, and all unnecessary pipe
plugs.
6. Oil lubricated frames.
Drain rust preventative oil from frames and replace
with fresh oil. Note some rust preventative oils such as
the Mobilarma 500 can be used in the bearing frame
for start-up and initial running. Check the supplier’s
technical data and the pump instruction book to ensure
the oil used is of suitable viscosity and grade for the
intended application. If this is the case, drain the oil
from the bearing frame to the level indicated on the
sight gauge. When the oil used to protect the bearing
frame is used to run the pump on start-up, this oil
should be changed initially at half the recommended
time for oil changes (see instruction manual). Remove
tape from breather and seals.
7. Grease lubricated frames.
No special methods are required to prepare for
start-up. The corrosion inhibitor oil can be left in the
frame. Remove tape from breather and seals.
If the pumps are started with the factory supplied
grease, it is recommended that they be re-greased
initially at half the recommended grease interval.
