Pumps from different manufacturers with the same parameters have different powers.

With the same parameters, why do pumps selected by different manufacturers have different powers? Example: 200 square meters, 32 meters, density 1, water A manufacturer: IHW150-315(I) 30KW Level 4 B manufacturer: IH150-125-315 37KW Level 4 C manufacturer: IHF150-125-315 45KW level 4, what’s the difference? Why is the power different? . .
The efficiency is different, and the safety factor of motor selection is also different.
A more efficient pump has a smaller motor, right?
The first direct-coupled pump, the second coupling drive. The third one is also a coupling, but lined with fluorine.
The efficiency of motors from different manufacturers is different, and sometimes it is related to the losses caused by the design of the pump structure. It is just a personal opinion. It is recommended to purchase products from major manufacturers. You can also use the same model of products from different manufacturers under the same working conditions. The advantages and disadvantages can be seen at a glance.
Considering environmental issues, the seal flushing scheme is different, that is, the power consumed by the seal is also different. The hydraulic models of different manufacturers are different, which causes the efficiency of the pump to be different. The safety factors of each manufacturer are also different, and some choose larger ones. Considering that the working conditions may change in the future, the motor does not need to be replaced.； Some manufacturers choose according to working conditions. Various factors result in different power of the selected motor, but the main factor is the high or low efficiency of the pump.
