Vertical Axial Flow Pumps
Axial flow pumps are used in handling sewage from commercial, municipal irrigation, river intake and industrial sources. In agriculture and fisheries very large horsepower axial flow pumps are used to lift water for irrigation and drainage. Axial flow pumps are also used as transfer pumps and for sailing ballast.
In power plants they are used for pumping water from a reservoir, river, lake or sea for cooling. In the chemical industry, they are used for the circulation of large masses of liquid, such as in evaporators and crystallizers. In sewage treatment, an axial flow pump is often used for internal mixed liquor recirculation.
Range of Sizes:
Size: Up to 1200 mm Delivery
Capacity: Up to 7500 m3 / hr
Head: Up to 15 m
Speed: Up to 1780 RPM
These type of suspended shaft vertical pump is a single – stage, propeller type machine. In axial flow pumps, the impeller pushes the liquid in a direction parallel to the pump shaft. Axial flow pumps are sometimes called propeller pumps because they operate essentially the same as the propeller of a boat. The main advantage of an axial flow pump is a relatively high discharge at a relatively low head.
