Efficient, Economical Pumping Solutions
The following Excel spreadsheets can be provided, both as a blank workbook and a completed example:
Epump Audit Gauge method
This provides an estimate of energy savings where there are pressure gauges fitted to the pumps. The readings are compared to the pump performance curve and proposed modifications are made.
Epump Audit System Calc method
Where pressure gauges are not available, an estimate of pump generated head is made from physical measurements of the pipework system. For single diameter, single pipe systems only.
Epump Audit Variable Demand
Where there is varying flow rate - for instance in heating or cooling installations or water supply with several draw off points.
Epump System Curve and NPSH Calculator
Generates a system curve from pipework measurement and allows a quick calculation of Nett Positive Suction Head Available. This will confirm correct operation and help eliminate troublesome pump applications.
Epump Laminar Flow System Curve and NPSH
As above system curve calculator, but for laminar (streamlined) flow for more viscous applications.
Epump Life Cycle Costing - Simplified Version
A simple life cycle cost spreadsheet which will allow comparison of three pumps. Costs included are Initial capital cost, Installation, Maintenance, Energy and Decommissioning. An example is included in the workbook.
All spreadsheets are Microsoft Office Excel 2007 format and graphics may be different if using earlier versions of Office. They should be used in conjunction with "A Simple Guide to Energy Saving Audits for Centrifugal Pumps" which is supplied in Adobe Acrobat Reader (PDF) format and/or printed and bound in quality ring binder.
