50 Hz duty point: Franklin’s table gives 27 m head at 3 m³/h for this exact model. The listed electrical input (P1) is 0.81 kW, distinct from the motor output in the title. Allow for pipe losses and required delivery pressure when selecting the pump.

Select the pump from the required flow and total dynamic head using the ES3/4 performance curve, not from motor power alone. Confirm water quality, duty cycle, pipe size, cable route and electrical protection. Position the float so it can move freely and never suspend or retrieve the pump by its power cable.
