H. Extended Storage
Appendix H—Extended Storage Procedures
If the pump is to be removed from service for some time, it must be protected as propane, butane, and anhydrous
ammonia all leave the metal “bare” and open to corrosion. Piping and tanks not in service should also be protected, as
the rust particles can destroy the pump’s seals almost immediately after startup.
1. Fill or thoroughly flush the pump with a light rust inhibiting oil. (If the pump is flushed with oil, place some
desiccant packets inside the pump for added protection.)
2. Plug all pump openings.
3. Store in a dry location.
4. Before placing the pump back into service, drain the oil and remove any desiccant packets.
5. Refer to the “Operation Procedures” on page 7 of this Installation, Operation and Maintenance (IOM) manual.
