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, it undergoes a series of transformations that are crucial for the efficient operation of the centrifugal pump.

Types of Centrifugal Pump Casing
Centrifugal pumps can have various types of casings designed to accommodate different operating conditions and fluid characteristics. Some common types of centrifugal pump casings include:
1. **Volute Casing:** The volute casing is one of the most widely used types of casing in centrifugal pumps. It consists of a spiral-shaped chamber that gradually expands in area to collect and direct the fluid discharged from the impeller.
2. **Circular Casing:** In contrast to the volute casing, the circular casing has a more uniform cross-section throughout its length. This type of casing is often used in high-speed pumps where a more streamlined flow path is required.
3. **Diffuser Casing:** The diffuser casing is designed to further increase the pressure of the fluid by converting its kinetic energy into pressure energy. It typically consists of a series of stationary vanes that decelerate the flow and guide it to the discharge port.
Volute vs Circular Casing Pump
The choice between a volute and circular casing pump depends on various factors such as the desired flow rate, pressure requirements, and efficiency considerations. Volute casings are known for their ability to handle high flow rates with moderate pressure increases, making them suitable for applications where a steady flow is essential. On the other hand, circular casings are preferred for high-speed pumps that require a more streamlined flow path to minimize energy losses.
Diffuser Casing in Centrifugal Pump
The diffuser casing plays a crucial role in enhancing the efficiency of a centrifugal pump by converting the kinetic energy of the fluid into pressure energy. By decelerating the flow and redirecting it towards the discharge port, the diffuser casing helps to increase the pressure of the fluid before it exits the pump. This is particularly important in applications where a significant pressure boost is required to overcome system resistance.
Volute Type Centrifugal Pump
A volute type centrifugal pump refers to a pump that utilizes a volute casing to collect and direct the fluid discharged from the impeller. Volute pumps are commonly used in various industries due to their simple design, ease of maintenance, and reliable performance. The spiral-shaped volute casing helps to minimize energy losses and turbulence, resulting in a more efficient pumping process.
Difference Between Volute and Diffuser
While both the volute and diffuser casings are essential components of a centrifugal pump, they serve different purposes in the fluid handling process. The volute casing primarily collects the fluid discharged from the impeller and gradually expands to convert the kinetic energy into pressure energy. In contrast, the diffuser casing further increases the pressure of the fluid by slowing down its velocity and guiding it towards the discharge port. Together, these components work in tandem to ensure optimal pump performance.
Centrifugal Pump Casing Design
The design of the centrifugal pump casing is critical to the overall performance and efficiency of the pump. Factors such as the type of fluid being pumped, operating conditions, and system requirements influence the casing design. Proper casing design is essential to minimize energy losses, reduce turbulence, and ensure smooth flow transitions throughout the pump. Engineers carefully consider factors such as impeller size, casing shape, and material selection to optimize pump performance.
Vortex Casing in Centrifugal Pump
In some centrifugal pumps, a vortex casing is used to create a swirling motion in the fluid before it enters the impeller. This swirling action helps to prevent air or gas entrainment in the pump, which can cause cavitation and reduce pump efficiency. Vortex casings are commonly used in applications where the pumped fluid contains entrained gases or solids that need to be separated before reaching the impeller.
Single Volute vs Double Pumps
What a cutwater is to a volute, vanes are to a diffuser. While volutes only have one (or sometimes two) points where the edge of the casing approaches the edge of the impeller in order to begin …
