  • An axial flow pump works like a corkscrew. It looks and works like a propeller. ( When you turn a corkscrew it bites into the cork and moves downwards. If you were to hold the corkscrew at a fixed height the cork moves up along the shaft of the corkscrew. The same happens with the fluid in an axial flow pump. The fluid travels through the blades of the impeller. A centrifugal pump also contains a series of rotating blades but this time the blades are designed to rotate the fluid in a cylindrical chamber. The fluid is rotated, but by Newton's first law it tries to continue in a straight line, which pushes it outwards - In the frame of the rotating fluid this is experienced as a centrifugal force whose magnitude is proportional to the distance from the center (and the square of the rpm) Thus there is a relatively low pressure in the center, and a high pressure at the side. Fluid introduced at the center is thus ejected from an outlet at the side.
