2.4 Storage
Store the pump in a clean, dry
location away from vibration. Leave piping
connection covers in place to keep dirt and other
foreign material out of pump casing. Turn pump at
intervals to prevent brinelling of the bearings and
the seal faces, if fitted, from sticking.
Do not store pumps starting on the fan guard.
The pump may be stored as above for up to 6
months. Consult Flowserve for preservative
actions when a longer storage period is needed.
