FLYGfrT a xylem brand ADDENDUM A Pump Storage For long periods of storage, the equipment must be protected against moisture and heat. The impeller should be rotated by hand (for example once every month) to prevent the Seal Rings from sticking together. Storing for 6 Months: In general, rotating machinery left idle for extended periods of time tend to establish a "set' position due to inaction of the moving parts. Some of these areas may be damaged (especially seals) from the sudden fast breakaway of start-up after a prolonged idle time. To insure that all rotating parts are free for final installation and start-up, it is good practice to rotate the Impeller/Propeller by hand at a minimum once a month. If the pump is stored for more than a six (6) month period, this rotation schedule is mandatory. For very long periods of storage it is good practice to relieve the tension on the Cable Entry sealing Grommet by backing off the Cable Entry compression screws slightly. If this is done, it is most important that a clear note be attached as a reminder to the equipment stating: "Re-Tighten Cable Entry Compression Screws Before Installation" Note: The backing off of the Cable Entry screws should onlV be done if the pump is stored in a dry protected area. Storing Up to 12 months: In addition to the above it is recommended the use of a silicon spray or rust inhibiting oil be sprayed through the pump outlet and up through the pump inlet so as to coat the Impeller/Propeller and the inside of the Discharge with a protective coating. Pumps should not be stored in a place where the ambient temperature may be in excess of 50°C for any length of time or drop below freezing 0°C. Any unit that may be exposed to ambient temperatures of 0°C or below must be emptied of any water what so ever. It is particular important that the Seal Oil Chamber only contain clean oil (no free water or oil-water emulsion would be allowed). After long periods of storage the pump should be fully inspected before it is put into service. Pay special attention to the Shaft Seal and the Cable Entry making sure the compression screws are tight. Pumps stored in their original shipping cartons/crates must be periodically removed from these cartons/crates in order to meet the storage mandate. A log showing dates in which the proper maintenance was performed is essential and will be required for review in the event a failure occurs after start-up following a prolonged period of storage. Further considerations that should appear in "the log" when storing product for prolonged periods twelve (12) months or more: 1) Drives should be stored without coolant 2) Pump Drives should be stored in the horizontal position 3) Impellers should be removed from the Shaft along with the Volute. 4) Shaft should be rotated monthly to protect Seals. 5) Power Cables should be set off of the pump and positioned in such a way that all strain removed from the cables
