Life Cycle Costs for Pumps

Toggle
OverviewAssumptionsReferences
  1. This calculator allows users to quickly estimate the total cost of installation and annual recurring costs for one or more pumps.
  2. Once the initial analysis is complete, you can go to the following link to conduct a detailed NPV analysis of your pumps: http://www.barringer1.com/
  3. Simply click on the "Life Cycle Cost Excel Spreadsheet" button to download a free copy of the worksheet.
  4. You can add any recommended preventative or preditive maintenance (PPM's) costs to "Total Annual Recurring Costs."
  5. You can add any recommended capital spare parts to "Total Cost of Installed Pumps."
  1. Pump and motor MTBR's are constant throughout the equipment's life.
  2. Average pump and motor repair cost are known and remain constant throughout the equipment's life.
  3. Power costs are constant. (An escalation factor may be used in Barriger's worksheet.)
