3. Shim all mounting feet on the driver until all
four readings are identical (0.005) maximum
Total Indicator Runout (TIR).
Proceed as follows with angular alignment:
1. Check the angular misalignment by
fastening dial indicator to one coupling
hub.
2. Set the dial on the indicator to zero and
rotate both hubs 360 degrees. With the
dial indicator needle in contact with the
surface of the outside diameter of the
opposite coupling hub, take indicator
readings at four points, 90 degrees
apart.
3. Adjust driver until all four readings are
identical (0.008 maximum TIR).
4. Reconnect coupling halves.
5. Reinstall coupling guard.
E. Piping
The pump is shipped with flange covers to
protect flange faces and to prevent foreign
matter from entering pump. Flange covers
should remain intact until suction and discharge
piping are connected to pump flanges.
All piping should be supported so that no undue
piping strain or weight is placed upon the pump.
Do NOT force piping. Never use pump as an
anchorage point for the piping.
caution
Extreme care should be taken when
connecting new piping to make sure that
no foreign matter such as dirt, slag,
chips, tools, etc., are in the piping.
Otherwise, the debris will be drawn into
the pump and will cause excessive
damage. During initial installation and
testing, a strainer should be installed in
suction piping to keep debris from
entering pump.
Suction lift lines should be laid with a
rising slope toward the pump and
positive suction-head lines should be
laid with a downward slope. This is done
to avoid air pocket formation. Suction
piping must be at least the same size as
pump suction nozzle. Compensation for
heat elongation must be provided where
required.
If necessary, the coupling should be realigned
after installing piping. Realign, if necessary, by
adjusting the driver end. Refer to Figure 6.
F. Auxiliary Connections
Connect auxiliary connections. For an illustration
of bearing cooling, refer to Figure 1, Water
Cooling. Figure 7, Fluid Line Schematic,
illustrates the heat exchanger and cooling water
for the seal.
