Inpro/Seal Co. Launches Return on Investment Calculation Worksheet

Spreadsheet calculates the impact of doubling MTBF of rotating equipment on plants’ bottom line

Rock Island, Ill.-based Inpro/Seal Co., manufacturer of bearing isolators, recently announced the availability of its Return On Investment Calculation Worksheet. (ROI/WS). An Excel spreadsheet module, the worksheet allows users of pumps and motors to quantify the effectiveness of bearing isolators when applied to rotating equipment. The worksheet allows plants to calculate their own ROI relative to the use of bearing isolators, including benchmarks of current repair costs and the effect of doubling the reliability of their rotating equipment.

End-users plug in their respective numbers to benchmark the amount of repairs and maintenance dollars saved by installing bearing isolators. Data entered includes: number of pumps and motors in operation; bearing isolator per unit costs; and the average Meantime Between Failures (MTBF). The worksheet then calculates the actual costs of the bearing isolators, taking MTBF and previous maintenance histories into consideration. The Return On Investment Calculation Worksheet can be downloaded from Inpro/Seal’s Web site.
