Pump Efficiency Calculation Tool

Introduction to spreadsheet

This tool calculates the energy efficiency and energy performance of water (and waste-water) pumping facilities. The following Help section explains some of the Inputs, Calculations and Outputs in this tool.

Main Inputs

• Electrical energy consumption (measured or nameplate)
• Run hours
• Static head (from drawings)
• Discharges pressure (from pressure gauge)
• Flow rate (from flow meter or estimate)
• Average unit price (electricity)

Main Outputs

• Motor, Pumping (Hydraulic) and System energy efficiencies
• Motor, Pumping & Piping Losses
• Total Energy Consumption & Energy Cost
• CO2 Emissions
• Energy Performance Indicators
• Comparison of Actual Performance v/s Best Practice Performance Certificate
