Axial flow pumpa pump that is driven by a force acting on a liquid by a blade of a rotating impeller to cause the liquid to flow along the axial direction.the wing hung in the fluid, the fluid with a certain speed when passing through the wing surface, wing back pressure, positive pressure, the pressure and the size of the wing and the angle of attack (wing back angle and flow direction of the fluid velocity and size) caused by a wing in a row, leading to a liquid (or gas) flow.Axial flow pump application:can transport water, mild sewage, medium temperature up to 40 degrees c, ph value of 4-10.
