volute type centrifugal pump|diffuser casing in centrifugal pump : purchaser A volute is a curved funnel that increases in area as it approaches the discharge port. The volute of a centrifugal pump is the casing that receives the fluid being pumped by the impeller, maintaining the velocity of the fluid through to the diffuser. As liquid exits the impeller it has high kinetic energy and the volute directs this flow through to the discharge. As the fluid travels along the volute i… Cavitation is the hydrodynamic phenomenon of liquid vaporization that occurs when the local static pressure value, p, becomes lower than the vapor pressure of the fluid, p sat.In centrifugal pumps, vapor cavities usually appear close to the suction of the impeller at the leading edge of the blades, where the flow is accelerated as it enters the rotating impeller and the .

A volute type centrifugal pump is a type of centrifugal pump that utilizes a volute casing to efficiently transfer fluid from the impeller to the discharge port. The volute casing plays a crucial role in maintaining the velocity of the fluid and directing the flow towards the discharge. In this article, we will explore the design, operation, and advantages of volute type centrifugal pumps.

Single Stage Centrifugal Pump Diagram
A single stage centrifugal pump diagram typically includes components such as the impeller, volute casing, and discharge port. The impeller is responsible for imparting kinetic energy to the fluid, while the volute casing ensures a smooth transition of the flow towards the discharge. The diagram also illustrates the direction of fluid flow and the key components involved in the pumping process.
Single Volute vs Double Pumps
Single volute and double volute pumps refer to the number of volutes present in the pump casing. Single volute pumps have a single curved funnel that increases in area as it approaches the discharge port, while double volute pumps feature two symmetrical volutes. Double volute pumps are known for their improved hydraulic efficiency and reduced radial forces compared to single volute pumps.
Volute vs Circular Casing Pump
The volute casing in a centrifugal pump is designed to gradually increase in area to accommodate the expanding flow of fluid from the impeller. In contrast, a circular casing pump has a constant cross-sectional area along its length. Volute casings are preferred for their ability to reduce turbulence and energy losses, resulting in higher pump efficiency.
Volute Constant Chart
A volute constant chart is a graphical representation of the relationship between the volute area and the flow rate in a centrifugal pump. By analyzing the volute constant chart, pump designers can optimize the volute geometry to achieve the desired performance characteristics, such as higher efficiency and lower head losses. The chart serves as a valuable tool in the design and analysis of volute type centrifugal pumps.
Diffuser Type Centrifugal Pump
Some centrifugal pumps feature a diffuser component in addition to the volute casing. The diffuser is located downstream of the impeller and serves to further decelerate the flow and convert kinetic energy into pressure energy. Diffuser type centrifugal pumps are known for their ability to handle high-pressure applications and provide a more stable flow output compared to pumps without a diffuser.
Volute Casing in Centrifugal Pump
The volute casing in a centrifugal pump plays a critical role in efficiently transferring fluid from the impeller to the discharge port. Its curved design helps to maintain the velocity of the fluid and minimize energy losses. Volute casings are carefully designed to optimize the flow path and ensure smooth operation of the pump. Proper selection and sizing of the volute casing are essential for maximizing pump performance.
Volute Pump Diagram
A volute pump diagram typically illustrates the key components of a volute type centrifugal pump, including the impeller, volute casing, and diffuser (if present). The diagram shows the flow path of the fluid through the pump and highlights the role of the volute casing in directing the flow towards the discharge. Understanding the components and operation of a volute pump is essential for efficient pump selection and maintenance.
