The useful power is applied to the fluid to meet the requirements of network throughput.
The ratio of useful power by the power consumption gives the yield of the pump.
- if the power absorbed is measured at the shaft of the pump, power ratio of useful power/ power absorbed gives yield of pump without motor
This curve shows for a given pump, the flow obtained after the power absorbed
It can be seen for example with a power of approximately 175W
This pump delivers: 6 M3 at 2 meters HMT, 2m3 to 5 meters ...
