Reed frequency vibration problems in vertical pump installations can be diagnosed and corrected in the field or avoided in initial design with these guidelines. Some vertical pump installations experience excessive vibration caused by a close match between the operating speed and the reed frequency. In these cases the driver and its support system vibrate as a cantilever beam similar to the reed in a musical instrument, hence the term ''reed frequency''. The driver may be any suitable prime mover, it makes little difference. However, for convenience we are assuming the driver is a large electric motor. Basic spring/mass system properties can be used to define and solve this structure resonance problem commonly called reed frequency vibration. Better yet, the problem can be avoided by properly using information available from motor and pump manufacturers. This article is intended to provide an overall perspective of the problem and suggest means to deal with it.
