Adjust the metal supports or wedges until the shafts of the pump and driver are level. Check the coupling faces as well
as the suction and discharge flanges of the pump for horizontal or vertical position by means of a level. Correct the
positions, if necessary, by adjusting the supports or wedges under the base plate as required.
Pumps and drivers mounted on a common base plate were accurately aligned before shipment.
All
base plates
are flexible
to
some extent and, therefore,
must not
be relied upon
to
maintain the factory alignment.
Figure 1. Foundation bolt location and anchorage
Realignment is necessary after the complete unit has been leveled on the foundation and again after the grout has set
and foundation bolts have been tightened. The alignment must be checked after the unit is piped and rechecked
periodically as outlined in the following paragraphs. To facilitate accurate field alignment, we do not dowel the pumps
or drivers on the base plates before shipment.
II-E. ALIGNMENT
Reliable, trouble free and efficient operation of a pumping unit requires correct alignment of pump and driver shafts.
Misalignment may be the cause of:
(a) Noisy pump operation
(b) Vibration
(c) Premature bearing failure (d)
Excessive coupling wear
