5. All internal surfaces in contact with water should be sprayed with Grade 5 of MIL-C-ISI73 Corrosion Preventive
Compound, solvent cut back. Drain all excess compound by removing drain plugs. Treat the drain plugs with P-I
or P-I9 preservative, replace and tighten.
6. Apply P-2 preservative to all exposed shaft surfaces.
7. Cover inlet and outlet nozzles with Grade A of MIL-B-I21 barrier material and a blank flange of mild steel
(1/16" minimum thickness), tempered hardboard (114" minimum thickness) or fully waterproofed plywood
(114" minimum thickness). Secure the flanges with at least 4 bolts with lockwashers.
8. Wrap the shaft, the frame and the stuffing box area with grease-proof barrier material, conforming to Type I,
Grade A of MIL-B-I2I. Secure the barrier with waterproof pressure sensitive tape.
9. Rotate the pump shaft several times by hand repeating this every two (2) weeks during storage. Rotation of the
shaft will coat the bearings and retard oxidation, preventing possible false Brinelling.
REMOVING FROM STORAGE:
After the storage period is over and prior to operating the pump, remove the cover on the thrust bearing housing for
inspection of the bearing lubricant. If any water or foreign matter is found in the lubricant, all bearings must be cleaned
and the lubricant replaced.
Refer to the Installation section of this manual for installation instructions.
After the pump has been set and grouted in place and is ready for operation, the following steps should be followed:
1. Reinstall the packing, seal water ring and gland. Adjust in accordance with this manual. Flush the mineral oil out of
the mechanical seal if unit is so equipped.
2. Remove bearing housing covers and remove one-half of the grease in bearing housings. Remove all grease relief
fittings and grease relief nipples from upper and lower bearing housings.
3. Start the pump per start-up instructions and permit grease to be purged from each bearing housing. Do not install
grease relief piping until purging has completely stopped after the pump has been in operation for at least eight (8)
hours. Observe bearing temperatures, and stop and start the pump or run it at reduced speed until temperatures
stabilize within the specified limits.
4. Stop the pump, wipe any grease off the shaft and bearing frame and place the pump in service per instructions in
this manual.
DANGER:
Do not attempt to clean the pump until electrical power has been disconnected and it has been verified that the pump
cannot start.
INSTALLATION:
Carefully read all sections of this manual and all other instruction manuals provided by manufacturers of other equipment
supplied with this pump.
