Volute in Indonesia
A volute is a spiral or scroll-shaped component commonly used in engineering, architecture, and art. In fluid mechanics and pump engineering, a volute refers to the casing of a centrifugal pump, designed in a spiral shape that gradually increases in cross-sectional area. Its primary function is to collect fluid discharged from the impeller and convert velocity energy into pressure energy before the fluid exits the pump.
In architecture and classical design, a volute is the spiral ornament often seen on the capital of Ionic columns, symbolizing elegance and balance.
👉 In summary, a volute can mean:
- Engineering (Pumps): Spiral casing that guides and slows fluid, increasing pressure.
- Architecture/Art: Spiral decorative element found in columns and scrolls.
Key Features of a Volute
- Spiral-Shaped Casing – Designed in a spiral or scroll form around the impeller.
- Gradually Expanding Area – Cross-sectional area increases progressively to slow down the velocity of the fluid.
- Energy Conversion – Converts kinetic energy of fluid from the impeller into pressure energy.
- Single Outlet Design – Directs the collected fluid toward the discharge nozzle.
- Uniform Flow Distribution – Ensures even collection of fluid from the impeller to minimize losses.
- Reduces Fluid Velocity – By increasing flow passage area, it decreases velocity and increases pressure.
- Hydraulic Efficiency – Improves pump performance by reducing turbulence and energy loss.
- Material Construction – Typically made from cast iron, stainless steel, or other corrosion/erosion-resistant materials.
- Applications – Commonly used in centrifugal pumps for water supply, chemical processing, sewage handling, and industrial pumping.
