- if the power consumption is measured at the shaft of the pump, the ratio of the output power by the power consumption gives the performance of the pump body without the engines
- If the power consumption is measured by power consumption of the pump motor, the ratio of effective power by the power input gives you the efficiency of your pump including engine efficiency.
Example of pump performance curve given in%:
Here the maximum efficiency is 57% (pump + motor)
Pump efficiency according to the flow in m3/heure
with Mecaflux standard
if you enter the efficiency of your turbine or pump, you will have, the power output or power consumption.
