A volute is a key hydraulic component in a centrifugal pump, forming the spiral-shaped casing that surrounds the impeller. It plays a critical role in converting velocity into pressure, ensuring efficient and stable fluid delivery. This design is widely used in industries such as water supply, agriculture, construction, mining, and fire protection systems.
As a professional pump manufacturer, Purity focuses on delivering high-efficiency volute centrifugal pump solutions designed for long-term reliability, energy savings, and stable industrial performance.
In a volute casing centrifugal pump, the volute is a gradually expanding spiral chamber that collects fluid discharged from the impeller.
When the impeller rotates, it accelerates the liquid outward, generating high velocity. The volute casing then slows the flow in a controlled manner, converting kinetic energy into pressure energy.
In simple terms, the volute ensures smooth energy conversion, stable pressure output, and improved hydraulic efficiency.
A volute centrifugal pump mainly consists of:
（1） Impeller – increases fluid velocity through high-speed rotation
（2）Volute casing – converts velocity into pressure and guides flow to the outlet
This simple but efficient hydraulic structure allows the pump to handle large volumes of liquid with stable performance and relatively low energy consumption.
