diffuser style centrifugal pump|volute vs circular casing pump : member club The stator section of a centrifugal pump, after flow exits the impeller, is usually either a ‘diffuser’ or a ‘volute’. The purpose of each of these two stator types is to efficiently diffuse velocity … The single stage, end suction centrifugal pump is the most common type of centrifu-gal pump. It has a single impeller stage . Vertical Multi-Stage Pumps A vertical multi-stage pump has multiple liquid chambers (stages) that are connected in series. Fluid enters the first chamber at

Reti, a Brazilian soldier and historian of science, documented the first machine that could be characterized as a centrifugal pump. It was a mud lifting machine that appeared in a treatise .
Centrifugal pumps are widely used in various industries for transferring fluids. Some centrifugal pumps contain diffusers, which play a crucial role in enhancing the pump's performance. A diffuser is a set of stationary vanes that surround the impeller. The purpose of the diffuser is to increase the efficiency of the centrifugal pump by allowing a more gradual expansion and less turbulent flow of the fluid. In this article, we will delve into the various aspects of diffuser style centrifugal pumps, including their design, benefits, and comparisons with other types of centrifugal pumps.

Centrifugal Pump Diffuser Reviews
Diffusers in centrifugal pumps are essential components that help in converting kinetic energy generated by the impeller into pressure energy. By providing a gradual expansion area for the fluid, diffusers help in reducing the velocity of the fluid and increasing its pressure. This results in improved efficiency and performance of the pump. Centrifugal pump diffusers are available in various designs and configurations, depending on the specific requirements of the application.
Volute Casing in Centrifugal Pump
In centrifugal pumps, the volute casing is a key component that houses the impeller and diffuser. The volute casing is designed to collect the fluid discharged by the impeller and guide it towards the discharge outlet. The shape of the volute casing plays a crucial role in controlling the flow of the fluid and optimizing the pump's efficiency. Volute casings are commonly used in centrifugal pumps due to their simple design and effectiveness in handling a wide range of fluid viscosities.
Axial & Radial Centrifugal Pumps
Centrifugal pumps can be classified into two main types based on the direction of fluid flow through the impeller: axial and radial pumps. In axial centrifugal pumps, the fluid enters and exits the impeller in the axial direction, parallel to the impeller shaft. This results in a linear flow path through the pump. On the other hand, radial centrifugal pumps have a tangential flow path, where the fluid enters the impeller radially and exits axially. The choice between axial and radial pumps depends on the specific requirements of the application.
Volute vs Circular Casing Pump
The casing of a centrifugal pump can be designed in various shapes, with volute and circular casings being the most common types. A volute casing has a spiral-shaped design that helps in converting kinetic energy into pressure energy efficiently. On the other hand, a circular casing has a simple circular shape and is often used in small, low-pressure applications. The choice between a volute and circular casing pump depends on factors such as flow rate, pressure requirements, and efficiency goals.
Diffuser Casing in Centrifugal Pump
In some centrifugal pumps, the diffuser is integrated into the casing itself, forming a diffuser casing. This design allows for a more compact and efficient pump configuration. Diffuser casings help in reducing the overall size of the pump while improving its performance by providing a controlled expansion area for the fluid. Diffuser casings are commonly used in high-efficiency centrifugal pumps for applications where space is limited.
Diffuser vs Volute Pump
The choice between a diffuser and volute pump depends on the specific requirements of the application. Diffuser pumps are known for their high efficiency and performance in handling high-pressure fluids. The presence of diffusers helps in reducing turbulence and improving the overall flow characteristics of the pump. On the other hand, volute pumps are more commonly used in applications where a simple and cost-effective design is preferred. Volute pumps are suitable for handling a wide range of fluid viscosities and flow rates.
Diffuser Type Centrifugal Pump
Diffuser type centrifugal pumps are designed with diffusers that are specifically optimized for enhancing the pump's performance. These pumps are ideal for applications where high efficiency and reliability are critical. Diffuser type centrifugal pumps are widely used in industries such as oil and gas, chemical processing, and water treatment. The design of the diffuser in these pumps is carefully engineered to ensure smooth flow and minimal energy losses, resulting in improved overall pump efficiency.
Centrifugal Pump Diffuser Design
There are mainly two types of casings used in centrifugal pumps: volute casings and diffuser casings. A volute casing is designed with a gradually flared, spiral-shaped channel that surrounds the impeller.
the pump less the vapour pressure converted to fluid column height of the liquid. Pump input or brake horsepower (BHP) is the actual horsepower delivered to the pump shaft. Pump output or water horsepower (WHP) is the liquid horsepower delivered by the pump. Pump Efficiency is the ratio of BHP and WHP.
