LONG TERM STORAGE OF
EQUIPMENT
The following procedure applies to horizontal and vertical
pumps only for storage of one month or longer. Access-
ories such as motors, steam turbines, gears, etc. must be
handled in accordance with the respective manufacturer’s
recommendations.
Follow the same procedure for temporary storage in
addition to the following:
Bearing Frames
Oil Lubrication
Pumps with oil lubrication are shipped from the factory
without oil in the bearing frame. To prepare these frames
for storage:
1. Fill the bearing frame full with a lubricating oil
containing a rust preventative such as Mobilarma 500
Series oil. If this oil is to be used for initial operation
of the equipment, care should be taken to select an oil
suited to the intended operating temperature of the
pump. Check the supplier’s technical data and the
pump instruction book for this information.
2. Seal all vents and apply a waterproof tape around the
oil seals in the bearing frames.
$
CAUTION
Prior to using, drain all oil from the frame in case any
moisture has accumulated. Then refill to proper level
using the correct oil specified in the instruction book.
Grease Lubrication
Pumps are shipped from the factory with the bearings
pre-greased and should require no further lubrication.
It is recommended, however, that if the pumps are to be
stored in a humid environment or outside, add ½ ounce of
corrosion inhibiting concentrated oil such as Cortec’s
VCI-329 to the frame. Seal all vents and apply a waterproof
tape around the grease seals in the bearing frame.
Stuffing Box
Packing
Remove gland, lantern ring, packing base ring (if
applicable), and packing from stuffing box. If the packing
is in good condition, it may be saved; otherwise, it should
be discarded. Thoroughly clean and dry interior of the
stuffing box and shaft sleeve. Coat all interior parts of the
stuffing box, except for stainless materials with a soft film
rust preventative such as Valvoline Tectyl 502C or Cortec’s
VCI-369.
Seal end of stuffing box with waterproof tape.
NOTE: This tape will have to be removed and replaced
when the shaft is rotated.
Store gland, packing base ring, packing and lantern ring
until pump is ready to be put into service.
Mechanical Seal
Double Face Seal
Open uppermost flushing tap on stuffing box and fill cavity
with a lightweight (#10-#20) rust preventative oil such as
Mobilarma 500.
Single Face Seal
Remove flushing water plug to stuffing box and spray an
oil base volatile corrosion inhibitor such as Cortec’s
VCI-329 into the stuffing box cavity. Be sure to coat as
much of the interior of the cavity as possible.
The above procedures are not required if the seal box is of
a stainless material.
For both types of mechanical seals, regardless of material,
seal all vent and drain lines. Seal the point where the shaft
exits the box using waterproof tape.
NOTE: This tape will have to be removed and replaced
when the shaft is rotated.
NOTE: The majority of mechanical seals provided
have elastomer materials made of Buna-N, Neoprene,
or Viton™ which are not affected by hydrocarbon
based lubricants. If your pump has seals with
materials other than the above, it will be necessary to
check the compatibility of that material with the
manufacturer of the rust preventative used.
Final Preparation – Pumps of Non-Stainless Material
Coat all exposed machined surfaces (flanges, faces, shafts,
exposed locating fits, etc.) with a firm rust preventative
such as Valvoline Tectyl 890. Place a volatile corrosion
inhibitor device in the pump casing such as Cortec’s VCI
309, 101, or 110, depending on the pump size and
application.
s
! WARNING
For potable water, food, beverage, etc., pumps, the
corrosion inhibitor must be non-toxic. FAILURE TO
FOLLOW INSTRUCTIONS COULD RESULT IN
INJURY OR DEATH.
Regardless of material, cement rubber diaphragm flange
covers over the suction and discharge flanges. Protect these
rubber diaphragm covers with hardboard material. Make
sure all vents, drains, or plugs are tightly sealed.
The pump is now ready to be placed in storage.
NOTE: Storage locations that are near a source of
vibration such as railroad or truck traffic, heavy
machinery, or impacting machinery must be avoided to
prevent false brinelling of the pump bearings.
