1. Select a clean dry storage location.
2. Be certain that blank flanges or cups covering pump openings are properly attached.
3. Store the unit free from heat, dirt, and vibrations.
4. Rotate pump shaft through several turns at least monthly.
5. If area where pump is stored or installed is a humid or dusty atmosphere:
•
Recoat all exterior, unpainted surfaces subject to corrosion with a rust-inhibiting compound.
•
Fill oil reservoirs completely full of oil. It is recommended that a tag be attached to the
housing indicating that it is full of oil.
•
Protect pump and driver with a plastic or canvas covering.
Fill cast iron or carbon steel pumps with oil. As an alternative the interior surfaces of the pump
can be misted with a suitable rust inhibiting compound and bagged desiccant placed in
accessible locations inside the pump. It is recommended that a tag be attached to the pump
indicating what internal preservation (e.g. filling with oil) has been made as well as the locations
of any desiccant bags.
Refer to the drive unit and coupling manufacturers for their long-term storage procedures.
For questions about possible long-term storage treatment services, please contact your local
CIRCOR sales representative.
