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 by power consumption of your engine pump, the ratio of useful power by the power consumption gives you yield pump including engine performance.

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 ...
