Comparison between Axial Flow Pump and Francis Pump

1, different than the number of revolutions, mixed flow pump is 300m3 / h-500m3 / h, axial flow pump is greater than 500m3 / h. 2, the flow through the impeller after the outflow of different directions (which is the main difference): Axial flow pump to maintain axial flow (parallel with the impeller rotation center), mixed flow pump is both axial and radial synthesis and the impeller rotation center into The angle of a certain angle. 3, the same flow, axial pump head lower than the mixed flow pump. The price is more expensive because the axial flow pump is vertical and this cheap mixed flow pump may be a horizontal volute type (since the flow of 1 m3 / s or 3600 m3 / h is very small for axial flow axial flow pumps , So the mixed flow pump may be horizontal volute type, while the axial flow pump although there are horizontal, but horizontal flow is not so small, horizontal motor cheaper than the vertical motor more)
