Operating Principle

Centrifugal pumps consist of an impeller, pump casing, and shaft assembly.

The impeller, driven by a motor, imparts kinetic energy to the fluid. As the fluid is thrown from the center toward the outer diameter, the velocity energy is converted into pressure energy within the volute casing, ensuring continuous flow.

Pump flow rate and pressure performance depend on parameters such as:

• Impeller diameter
• Rotational speed
• System resistance
