IV. PUMP APPLICATIONS
D. Pump storage
In order to prevent permanent damage to pumps which are placed in storage, the following procedures are recommended:
1. Short Term Storage
Recommended for period less than 6 months and a minimum requirement for any exported pumps or pump package units without customer procedures.
a. Where possible, place pump in an enclosed storage facility. If enclosed storage is not available, cover the entire pump and associated exposed attachments with a heavy tarpaulin.
b. Remove crankcase cover and fill the crankcase with lubricant (approved and specified on pump applications tag).
c. Replace crankcase cover.
d. Drain all fluids and remove; valve covers, cylinder heads, and inlet and discharge flange plugs.
e. Apply a film covering of lubricant to all exposed parts.
f. Remove cradle cover and coat plunger or rod surface with lubricant.
g. Replace valve covers, cylinder heads and inlet and discharge flange plugs.
h. Rotate crankshaft 10 complete turns and reapply liquid end protection, including plungers (as described in steps d, e, and f above), weekly.
i. Check for oil leaks around pump and replace gaskets or seals immediately if necessary.
Refer to engine, motor, gear reducer, etc. manufacturer's instructions for storage procedures. 2. Long Term Storage
Recommended for a period exceeding 6 months.
a. The pump and parts should be stored in a clean, dry location, free from temperature extremes, in an approximately level position and without distortion.
b. It is desirable to completely fill the power end (crankcase cavity, etc.) of the pump with the approved lubricant. Such a fluid level would ensure all parts within the power end are protected. To fill the power end, remove the hand cover and fill with lubricant. Be sure to replace the hand cover. Service the remainder of the pump as directed above in steps d-h.
c. Inspect periodically for possible oil leakage and replace gaskets or seals immediately if necessary.
Caution: Before placing the pump, engine, gear reducer, etc. into service, fill the crankcase with the manufacturer recommended lubricant and check for proper lubricant level.
Caution: Double acting piston pumps, having steel or file hard steel piston rods, require special attention.
Remove liquid end stuffing box packing in pumps having piston rods in these materials as they are subject to chemical and atmospheric corrosion, if left in contact with the packing.
Exposed sections of these rod materials must protected by a coating of heavy grease or rust preventative.
Each time the pump is rotated during storage, this coating must be checked and reapplied, if needed.
A heavy coating of lubricant is also recommended immediately after servicing or recommissioning the liquid end.
