should remain inside its shipping container. Furthermore, the pump unit (pump, driver, etc.) should
not be subject to sudden temperature changes or vibrations.
3.4.2 Long Term Storage (Longer than Six Months)
For long term storage each part of the pump should be individually prepared. Comply with the
following steps:
1. Remove pump from shipping skids and supports, but do not damage them because the
unit is to be placed in them again.
2. Remove all instruments and mechanical seal; store them safely.
3. Plug the instrument taps.
4. Thoroughly dry the pump with hot air.
5. Any painted surface damaged during shipment should be repainted or sprayed with oil.
6. Keep the pump moisture-free by the following two means:
a. Spray the pump case and bearing frame with acid-free, moisture-free, protective oil or
kerosene.
b. Place desiccant or humidor bags inside the suction and discharge areas of the pump.
Attach red tags with a “Remove Moisture Absorbent Material Bags Prior to
Installing” to warn about the presence of this desiccant material.
7. Cover all the openings with plywood or metal covers. Recheck the condition of these
covers every month and replace as necessary.
8. If the pump’s external parts have protective coatings, periodically inspect and renew the
coating as required.
9. Rotate the shaft 1 ¼ revolutions every week. Lubricate shaft bushings prior to rotation.
The client must keep a record of the weekly rotation of the shaft. Failure to
document and present these records as evidence will void the warranty.
10. Check the packaging for damage every month.
11. Ensure pump flange covers remain in place.
