Axial pumps or axial pumps are equipped with a vane mechanism with a fixed or interchangeable vane angle.
Operation is based on the force interaction of a vane with the flow around it. In axial pumps, the fluid flow is parallel to the rotation axis of the impeller. The axial pump consists of a casing and a vane wheel rotating freely in it. As the wheel rotates, there is a pressure difference in the fluid flow on either side of each vane, and therefore, a force interaction between the flow and the vane wheel. The forces of blade pressure on the flow create a forced rotational and translational motion of the fluid, increasing its pressure and velocity, i.e. mechanical energy. The specific incremental energy of fluid flow in a vane wheel depends on the combination of flow velocity, wheel speed, size and shape, i.e. the combination of pump design, size, speed and delivery.
Axial flow pumps can be of two types:
