6M-44GB 7000-NSF, 7100-NSF Vertical Turbine Pumps
Installation, Operation, and Maintenance
___________________________________________________________________________________________
F. Refer to the driver manual to assure that all safety procedures are completely understood and
implemented prior to operation.
Grease lubricated drivers are shipped pre-lubricated. Oil lubricated drivers and right angle gears are
shipped dry and require an initial fill of the manufacturer's recommended lubricant prior to start-up.
See driver manufacture's manual for lubrication specifications. Initial start-up lubricants are not
supplied by the manufacturer.
OPERATION:
General
Because variations may exist in both the equipment and in the particular installation of the a pump and driver,
specific operating instructions are not within the scope of this manual. However, there are general rules and
practices that apply to all pump installations and operation.
Before starting or operating the pump, read this entire manual, especially the following instructions.
Before starting the pump:
1. Rotate the unit or assembly by hand to assure all on moving parts are free.
2. Install coupling guards around all exposed rotating parts. Guards are mandatory on discharge head
(motor pedestal) openings if the pump is equipped with an adjustable coupling.
3. Install packing (or mechanical seal).
4. Install water line to packing box (for water flush or mechanical seals).
5. Observe all DANGER, WARNING and CAUTION tags attached to this equipment.
6. Ensure water in sump is at the specified level for adequate submergence.
7. If pump has a packed box, adjust the packing gland finger tight. Refer to Packing Adjustment in the
maintenance section to properly adjust packing.
If excessive vibration or noise occurs during operation, shut the pump down and review the Trouble Shooting
section. If the problem cannot be corrected, consult a Fairbanks Nijhuis™ representative.
Operating at Reduced Capacity
In a typical application covering a wide range of flow rates a variable speed driver is often used to adjust
pump and this is taken into consideration by Fairbanks Nijhuis™ when selecting the pump and impeller trim.
Although these pumps are applicable over a wide range of operating conditions, care should be exercised
when doing so when the actual conditions differ from the sold conditions. You should always contact your
nearest Fairbanks Nijhuis™ distributor or factory before operating the pumps at any condition other than that
for which they were sold.
Generally, these pumps can be operated continuously at capacity equal to 60% of the pump capacity at the
best efficiency point, and at higher capacities.
Initial Startup
Inspect the complete installation to ensure that the installation instructions of this manual, and the manuals of
all the related equipment, have been followed and that the installation is complete.
Ensure that the driver is properly serviced, and that the proper pump rotation is obtained.
Rotate the pump shaft by hand. It should rotate freely on motor driven installations.
