Runout of rotating equipment is defined as the amount to which the coupling or the shaft deviates from true circular rotation. The deviation is caused by either a bent shaft or by an incorrectly drilled coupling that rotates eccentrically.
First determine if the runout is being caused by a bent shaft or a coupling problem, or both. The shaft and/or the coupling may need to be replaced.
Pipe strain is caused by the misfit of the connection between the pump flange and the piping.
The Probe can be mounted to read either the pipe flange, or the piping, or the effects of the pipe strain at the coupling. Adjustments can then be made to reduce the strain.
