Centrifugal Pump Selection Aid
Centrifugal pumps are a popular type of pump used for various industrial applications, including fluid handling, wastewater management, and chemical processing. In this blog, we will discuss the different types of centrifugal pumps and their key features.
End-Suction Centrifugal Pumps: End-suction centrifugal pumps are the most commonly used type of centrifugal pump. These pumps have a single inlet and outlet, and the impeller is located at the end of the shaft. They are ideal for low-viscosity fluids and are often used in water supply and HVAC applications.
Single suction and discharge port
Easy to install and maintain
Suitable for low-viscosity fluids
Split-Case Centrifugal Pumps: Split-case centrifugal pumps have a horizontally split casing, which allows for easy access to the internal components. The impeller is located between the casing halves, and the suction and discharge nozzles are located on the top of the casing. These pumps are ideal for high-flow, low-to-medium pressure applications.
Horizontal split casing for easy maintenance
Double suction impeller for balanced flow
Suitable for high-flow, low-to-medium pressure applications
Can handle solids up to a certain size
Vertical Inline Centrifugal Pumps: Vertical inline centrifugal pumps have a vertical orientation, with the motor located above the pump. These pumps have a single impeller and are often used in HVAC and water supply applications.
Vertical orientation for space-saving installation
Single impeller for simple operation
Easy to maintain
Suitable for low-to-medium flow applications
Multistage Centrifugal Pumps: Multistage centrifugal pumps consist of two or more impellers mounted on a common shaft, which allows for increased pressure and flow rate. These pumps are often used in high-pressure applications, such as water treatment and chemical processing.
Multiple impellers for increased pressure and flow rate
Suitable for high-pressure applications
Can handle low-to-medium viscosity fluids
Often used in water treatment and chemical processing
Self-Priming Centrifugal Pumps: Self-priming centrifugal pumps are designed to remove air from the suction line and prime themselves without external assistance. These pumps are often used in applications where the pump is located above the fluid level.

Ideal for applications where the pump is located above the fluid level
Suitable for low-to-medium viscosity fluids
Often used in water supply and wastewater treatment applications
In conclusion, there are various types of centrifugal pumps available, each with its own unique features and benefits. The choice of pump will depend on the specific application and fluid being handled. It's important to choose the right pump for the job to ensure efficient and reliable operation.
