Performance characteristics of mixed flow pump, centrifugal pump and axial flow pump

First of all, centrifugal pump includes part of mixed flow pump, which should be classified as runoff pump, mixed flow pump and axial flow pump. This is classified according to the direction of outflow.

Specific speed from low to high.

Centrifugal pump generally has small flow, high head and low specific speed. The specific speed is generally less than 200.

Axial flow pump has large flow, low head, high specific speed, generally more than 400.
