In Centrifugal pumps, the impeller rotates and drives the water to the periphery towards the casing. The vortex thus creates has a low pressure region in the center. This low pressure region is called the eye of the impeller.
Centrifugal pumps play a crucial role in various industries, from oil and gas to water treatment and manufacturing. Understanding the suction and discharge pressure of centrifugal pumps is essential for ensuring optimal performance and efficiency. In this article, we will explore the importance of centrifugal pump suction and discharge pressure, common problems associated with suction tanks, characteristics of centrifugal pumps, and guidelines for proper suction and discharge piping.
While some pump manufacturers that use pressure (differential pressure which is measure the deviation
Why Centrifugal Pump is Used
Centrifugal pumps are widely used in industries for their ability to efficiently move fluids. Unlike positive displacement pumps, centrifugal pumps rely on centrifugal force to generate velocity and create pressure. This makes them ideal for applications where a continuous flow of fluid is required at a consistent pressure.
Centrifugal Pump Suction Tank Problems
One common issue with centrifugal pumps is cavitation, which occurs when the pressure in the suction tank drops below the vapor pressure of the liquid being pumped. This can lead to the formation of vapor bubbles, causing damage to the pump impeller and reducing efficiency. Proper design and maintenance of suction tanks are essential to prevent cavitation and ensure smooth operation of the pump.
Characteristics of a Centrifugal Pump
Centrifugal pumps are known for their simplicity, reliability, and versatility. They can handle a wide range of flow rates and pressures, making them suitable for various applications. Some key characteristics of centrifugal pumps include high flow rates, low maintenance requirements, and the ability to handle abrasive or corrosive fluids.
End Suction Centrifugal Pump Catalogue
When selecting a centrifugal pump for a specific application, it is important to consider factors such as flow rate, head, efficiency, and material compatibility. End suction centrifugal pumps are a popular choice for many industrial applications due to their compact design and ease of installation. Consulting a pump catalogue can help in choosing the right pump for the job.
Centrifugal Pumps Not Sucking
If a centrifugal pump is not able to draw in fluid effectively, it may be due to issues with the suction piping or air leaks in the system. Properly sizing and installing suction piping is crucial for ensuring that the pump can create the necessary suction pressure to lift the fluid. Regular maintenance and inspection of the pump system can help prevent issues with suction.
How Does Centrifugal Pump Work
Centrifugal pumps work by converting mechanical energy from a motor into kinetic energy in the form of fluid velocity. As the fluid enters the pump impeller, it is accelerated and pushed towards the outer edge of the impeller. This creates a low-pressure zone at the center of the impeller, causing more fluid to be drawn in through the suction pipe. The fluid is then discharged at a higher pressure through the pump outlet.
Centrifugal Pump Suction Piping Guidelines

A coupling transmits power from a driver to a driven piece of equipment. The driver can be anything from an electric motor to a steam turbine, and the driven equipment can be a gearbox, fan or pump. While the coupling is often viewed as the weak link in the pump assembly, replacing a coupling element is still much easier than replacing a sheared shaft.
