What Is The Difference Between Having One More And One Less Large Impeller For Submersible Pump Motors With The Same Power?

Oct 24, 2024

The same power and diameter, with more impellers, result in higher head. The head is inversely proportional to the flow rate, because the premise is the same power, so the flow rate with more impellers is smaller. The above refers to the maximum value. In actual use, it may vary. For example, when the pump outlet resistance is high, with the same power, more impellers will have a larger flow rate.
