SECTION VI. PREPARATION FOR STORAGE OR SHIPMENT
2-15. General. If the Bilge/Ballast Pump will remain intact in the supply system for an extended period of time (30
days or longer), or if the pump assembly is to be reshipped to another location, certain actions must be taken as
protection against the corrosive effects of the elements. All internal and external surfaces will rust or corrode if they are
not protected. The procedures in the following paragraphs will cover preservation of the Bilge/Ballast Pump prior to
extended lay-up or shipping. Also see TB-740-97-4, Preservation of Vessels for Storage, and TM 55-1905-223-24-18,
Hull and Outfitting.
2-16. Temporary Storage Bilge/Ballast Pump. The following tasks cover preservation of the Bilge/Ballast Pump with
system intact and reshipment to another location to minimize rust or corrosion.
Short-term Storage, System Intact (30 days or less). Operate pump to
rotate the shaft several revolutions every week to coat the bearings with
lubricant, retard oxidation or corrosion, and prevent possible denting of
bearing housing. Shaft extensions and other exposed machine surfaces
should be coated with an easily removable rust preventative conformng to
Short-term Storage or Shipping (30 days or less).
(1) Flush pump and seal with clean fresh water and dry with compressed air.
(2) Cement rubber diaphragm flange covers over the suction and discharge
flanges. Install hardboard covers over the rubber to protect from
damage and ensure that all vents, drains, and plugs are tightly sealed.
(3) Store pump in well-ventilated area under cover, out of direct sunlight,
and protected from dirt, dust, and weather.
(4) When sealing pump in container for shipping, place a suitable amount of
desiccant to ensure dryness and prevent moisture buildup. For guidance
use MIL-STD-107, Preparation for Shipping and Storage, and MIL-STD-129,
Marking for Shipment and Storage.
Long-term Storage, System Intact (Over 30 days).
(1) Move the suction and discharge valves closest to the pump in closed
position as tight as possible and flush pump, seal, and piping with
clean fresh water.
(2) Remove all water, dry with compressed air, and flush pump, seal, and
piping with type P-3 preservative.
(3) Remove drain plug and drain off excess preservative, coat the drain
plug, and reinstall in pump casing.
