Should Soft Foot Be Corrected in Centrifugal Pumps?
In a previous blog I wrote in Jan of 2016 “Soft Foot Concerns in the Stationary Machine?” soft foot in the pump was causing repeatability issues during a precision shaft alignment.

Soft foot can also distort the pump casing which can change clearances within the casing.
This can shorten the life of the bearings and seals, change clearances between the impeller and volute negatively affecting pump performance and cause vibration issues.
Therefore, the answer is yes! If you have feet on your centrifugal pump and bolts holding it to a base, soft foot should absolutely be checked for and corrected.
