What component does a double volute casing contribute to in a pump?

• A. Increased pressure
• B. Guiding vane
• C. Noise reduction
• D. Fluid storage

Answer: (B)

A double volute casing in a pump plays a crucial role in managing the hydraulic performance of the pump by effectively distributing the flow of fluid and minimizing pressure fluctuations. The design features two volutes which allow for improved balance of the hydraulic forces acting on the impeller. This helps in guiding the flow of fluid more efficiently after it exits the impeller, optimizing flow direction towards the discharge port. The guiding vane functionality reduces turbulence and helps provide a smoother flow path, ultimately resulting in enhanced pump efficiency and performance. While double volute casings may also have secondary benefits relating to noise or pressure distribution, their primary purpose is to guide the flow of fluid as it is discharged from the pump, ensuring that the impeller's output is directed optimally and reducing the risk of cavitation or excessive vibrations that can arise from uneven pressure distribution.
