• Axial Flow Centrifugal Pumps  

Axial flow centrifugal pumps manufacturers are a specific type of centrifugal pump that designed to move fluid in a direction parallel to the pump shaft.  

The impeller forces the fluid to flow parallel to the shaft. This flow pattern resembles that of a propeller.  

Advantages and limitations  

Advantages:  

• Ability to move fluids at a high flow rate with a low head.  

• More effective in transporting substantial quantities of fluid.  

• Good for low-pressure applications with limited space.  

Limitations:
