What type of propeller pump moves fluid partly by centrifugal force?

The mixed flow propeller pump is characterized by its ability to move fluid partly by centrifugal force and partly through axial movement. In this type of pump, the design allows for the combination of axial flow, where the fluid flows parallel to the pump shaft, and centrifugal flow, where the fluid is propelled outward from the center of the pump due to the rotation of the impeller.

This unique flow mechanism enables mixed flow pumps to efficiently handle fluids with varying viscosities and flow rates, making them versatile for different applications. They are particularly useful when a balance between pressure and flow rate is required, leveraging both types of fluid movement to maintain performance.

In contrast, axial flow pumps primarily utilize axial motion to move fluid without significant centrifugal effects, while radial flow pumps focus on centrifugal force alone. Diaphragm flow pumps operate using a completely different mechanism involving a flexible diaphragm to create flow, which does not integrate centrifugal movement at all.
