- Axial flow pump
An axial flow pump, or AFP, is a common type of
water pumpthat essentially consists of a propellerin a tube. The propeller can be driven directly by a sealed motorin the tube or by a right-angle drive shaft that pierces the tube.
The main advantage of an AFP is that it can easily be adjusted to run at peak
efficiencyat low-flow/high-pressure and high-flow/low-pressure by changing the pitch on the propeller.
These pumps have the smallest of the dimensions among any of the conventional pumps and are more suited for low heads and higher discharges.
An application example of an AFP would be transfer pumps used for
sailing ballast. In chemical industry, they are used for the circulation of large masses of liquid, such as in evaporators and crystallizers.
