Structural vibration can be a problem with most machines, particularly with vertical turbine pumps. These pumps are commonly suspended from the discharge elbow with the motor mounted above, making them difficult to stiffen and damp. With low stiffness and damping, natural vibration frequencies in the machine operating range are inevitable, as well as reliability issues from excessive vibration ...

Amplified response causes of vibration are generally more complex to analyze. They result from operation at speeds close to a mechanical or hydraulic resonant frequency of a major pump, foundation or pipe component. This is of special concern with variable speed, large multistage horizontal and/or vertical pumps.

Evaluating and Correcting Subsynchronous Vibration in Vertical Pumps By Malcolm E. Leader, P.E. ... The first pump was installed in the interior (West) slot with shorter pipe runs. When that pump was placed in service, elevated vibration was detected on the motor at 0.20 IPS ... Evaluating and Correcting Subsynchronous Vibration in Vertical ...

Vibration is a leading cause of piping fatigue failures and can cause safety risks, environmental damage and downtime. Traditional pipe clamps often do not produce a satisfactory solution for vibratory loads. The vibration can be shifted elsewhere on the structure, or the clamp is not effective at all operating speeds or conditions.
