Pumps alignment
Pumps alignment
(OP)
KSB pumps were installed and will be realigned , the pumps are Multitec Horizontal Booster pumps , at the O&M manual it was indicated that : "The radial and axial deviation between th two coupling halves must not to exceed 0.1mm".
From your experience of pumps alignment can you tell me what are the best tools that you recommend for aligning the pumps and what is the accuracy needed for the tools ??
Does it need to be lazer alignment tools ??
any inputs about the KSB pumps alignment are highly appreciated ..
Thanks

tools - dial indicator with 0.001-inch scale capabilities, a straight edge of length equal to or greater than the coupling, and a skilled mechanic.
yes, laser alignment tools can be used, but i do not know the expense (compared with the dial indicator).
these two websites may be beneficial:

There are laser alingment companies and/or pump repairers specialising in laser alignment of rotating equipment, and would suggest you try some of these local to you.

Besides the initial alignment you also need to check once all pipe loads are in place, after the pump comes up to operating temperature as well as a week or two after start-up.
It is worth the effort to put time into correct alignment as it will ensure long life of bearings, seals,coupling life and less vibration of the pump and pipework.

What type/style of coupling?
IMO Any alignment using the coupling features ( OD or face) must first establish the runout of those features. I've been hurt badly assuming any feature runs "true."
The bypassing of coupling hub runout is one big advantage of both reverse indicator (once indicator or bracket sag is measured and compensated for) and laser methods.
