entering the pump.

8. Disconnect the piping from the pump if you heat one side of the pipe to align the pipe to the
pump.
9. Pump and pipe flanges must be parallel; they should mate together without effort, and with
the bolt holes properly in line.
10. Check the fine alignment by clocking or using a Dial Type Indicator (DTI) on the coupling.
Check the operating instruction for the coupling.
11. Connect and tighten the suction pipe and compare the alignment with the values of the fine
alignment. In the case of deviations, warm the pipe so that the values of the fine alignment
are reached.
When heating takes place close to the flange, there is a danger that the flange seal
will become rippled and leaky. No more welding work can be carried out on the
piping when it is screwed to the pump.
12. Proceed in the same way with the discharge pipe.
Make sure that there are isolation block valves at the pump for each type of
auxiliary piping.
Consider a slope in the suction piping to avoid high points.
