Limiting Vibration Issues in Vertical Turbine Pumps ...

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.
