1.1.5 vibration levels
Armstrong Vertical In-Line pumps are designed to meet
vibration levels set by Hydraulic Institute Standard hi Pump
Vibration 9.6.4. Standard levels are as detailed below:
1.1.6 storage
Pumps not immediately placed into service, or removed from
service and stored, must be properly prepared to prevent
excessive rusting. Pump port protection plates must not be
removed until the pump is ready to connect to the piping.
Rotate the shaft periodically (at least monthly) to keep rotat-
ing element free and bearings fully functional.
For long term storage (longer than three months), the pump
must be placed in a vertical position in a dry environment.
Internal rusting can be prevented by removing the plugs at
the top and bottom of the casing and drain or air blow out all
water to prevent rust buildup or the possibility of freezing. Be
sure to reinstall the plugs when the unit is made operational.
Rustproofing or packing the casing with moisture absorb-
ing material and covering the flanges is acceptable. When
returning to service be sure to remove the drying agent from
the pump.
