Unlike imbalance, misalignment does not produce forces that are similar in the radius of the machine. Vibration in one radial direction may be very different in amplitude when compared to vibration in another radial direction. This is one instance where amplitude readings are not only helpful in detecting a problem but also helpful in diagnosing a problem. Misalignment can result in a machine having high vertical vibration on one end and high horizontal vibration on the other with other radial readings remaining low. Imbalance is not likely to cause this amplitude pattern.

Going green is not something to be taken lightly. Not only is our livelihood at risk, but our very lives may also depend on how well we meet the challenges of living green. To cover all the benefits of going green would require multiple, book-length documents; therefore, we will limit this discussion to the green benefits of precision machine alignment. Precision alignment produces these types of benefits in four areas: energy savings, improved machine life, better products, and less pollution.

Vertical pumps are designed to be “self-aligning” due to the rabbet fit between pump and driver, thus eliminating the need for precision shaft alignment. Notwithstanding these advantages, this article will focus on the need for the alignment of vertical pumps.
