The following are suggested steps to establish the initial alignment of the pumping unit.
NOTICE:
This is an initial alignment. The final alignment is done after the unit has been run under actual
operating conditions. The final alignment procedure is outlined in Section Alignment - final and
must be followed.
1. Be sure coupling halves are disconnected.
2. Tighten foundation bolts.
3. Tighten pump and driver hold-down bolts.
4. Any coupling manufacturer's instruction sheets sent with the pump should be studied and used
when installing, aligning, or servicing coupling. Align coupling, following manufacturer's instructions.
If instructions are not available, the following procedure (Steps 5 and 6) may be used.
5. Check angular misalignment - shaft axes concentric but not parallel - by inserting a taper gauge or
feeler at four points on the circumference of coupling halves at 90° intervals. See
Figure 3: on page
12 . The unit will be in angular alignment when the measurements show the coupling faces are the
same distance apart at all points. The "gap" between the coupling halves should be checked at this
time. This depends on the type of coupling used and this information will be found in the instructions
for the specific make of coupling furnished. It is normally 1/8-1/4" for most applications. Adjust an-
gular alignment and "gap" by loosening the driver hold-down bolts and shifting or shimming driver
as required. Tighten driver hold-down bolts after angular alignment and correct "gap" are secured.
Figure 3:
NOTICE:
Pumps and drivers are bedplated so that when coupling faces are positioned in accordance
with the manufacturer's recommended gap, there is an overhang of approximately 1/8" from
shaft ends to coupling hub faces.
