PUMPFDN - PUMP FOUNDATIONS SUPPORTED ON SOIL


I know that many of us probably merely use the simplistic approach of a weight (mass) ratio for determining the minimum size of pump foundations. That is usually adequate for small pumps. However, this spreadsheet workbook will hopefully provide you with tools, using at least a bit more sophisticated rationale, for sizing large pump foundations in particular. The calculations in the "Large Pump" worksheet are quite similar to those that I and many others have performed by hand in years past for pumps and compressors.

For a concise explanation of what is in the workbook, I've copied the text directly from the "Doc" worksheet of the workbook and included it below.

------------------------------
"PUMPFDN" is a spreadsheet program written in MS-Excel for the purpose of analyzing "block-type" foundations for both small and large pump packages. Specifically, for small pump packages less than 5,000 lbs. in total weight, the foundation is analyzed in a simplistic manner involving only the mass ratio and the vertical mode natural frequency. For large pump packages equal to or greater than 5,000 lbs. in total weight, a simplified dynamic machine foundation damped vibration analysis is performed for the vertical, horizontal, and rocking modes for the purpose of evaluating foundation performance as related to peak-to-peak vibration amplitudes and peak vibration velocities. The soil bearing pressure is also checked, for both static and dynamic conditions.
