SHORT-TERM STORAGE:
Short-term storage is when the pump will be stored for periods not exceeding three months. The following are the short-
term storage requirements:
A. Rotate the shaft for several revolutions at least once every two weeks to:
1. Coat the bearing with lubricant.
2. Retard oxidation or corrosion.
3. Prevent possible false Brinelling.
LONG-TERM STORAGE:
Long-term storage is when the pump will be stored for periods exceeding three months. The following are long-term
storage requirements:
THREE MONTHS TO ONE YEAR:
1. Remove gland halves, packing and seal water ring from the stuffing box. Package them in a suitable container to
prevent loss or damage. Coat the inside of the stuffing box with grease.
• If the pump is equipped with a mechanical seal, remove the pipe plug in the stuffing box and pour at least 4
ounces of mineral oil into the seal housing. Reinstall the pipe plug.
2. Fill the bearing housings with specified lubricating grease until grease exits from relief fittings.
3. Wipe clean all exposed machined surfaces and coat with a heavy layer of grease or other equivalent rust
prevention material.
4. Cover the suction and discharge of the pump with cardboard or wood to prevent entry of foreign material
or varmints.
5. Rotate the pump shaft several times by hand repeating this every two (2) weeks during storage. Rotation of the
shaft will coat the bearings and retard oxidation, preventing possible false Brinelling.
OVER ONE YEAR:
1. Remove gland halves, packing and seal water ring from the stuffing box. Package them in a suitable container
to prevent loss or damage. Coat the inside of the stuffing box with grease.
• If the pump is equipped with a mechanical seal, remove the pipe plug in the stuffing box and pour at least 4
ounces of mineral oil into the seal housing. Reinstall the pipe plug.
2. Fill the bearing housings with specified lubricating grease until grease exits from relief fittings.
3. Clean all accessible machined surfaces to remove dirt, corrosion, grease and any other foreign matter. Clean
water passages to remove all foreign matter. Dry the pump to remove all moisture.
4. Spray flushing water and seal water piping with P-7 medium preservative oil. Seal all water inlet connections
with pipe caps or plugs.
