The design of the volute is crucial for the efficiency of the pump. A well-designed volute minimizes flow separation and turbulence, ensuring a smooth transition of the fluid from the impeller to the discharge pipe. The volute shape is typically spiral, which facilitates a uniform flow distribution. If the volute is improperly designed, it can lead to inefficiencies such as cavitation, vibrations, and noise, significantly affecting the pump's overall performance.
