Why Centrifugal Pump is Used
Centrifugal pumps are preferred in many applications due to their ability to handle a wide range of flow rates and pressures. These pumps are commonly used for transferring liquids in industries such as oil and gas, water treatment, chemical processing, and more. The simplicity of their design, low maintenance requirements, and high efficiency make centrifugal pumps a popular choice for various fluid handling tasks.
Centrifugal Pump Suction Tank Problems
One common issue that can arise with centrifugal pump suction is related to the design and operation of the suction tank. Improper sizing or configuration of the suction tank can lead to issues such as air entrainment, vortex formation, and inadequate fluid supply to the pump. It is essential to ensure that the suction tank is properly designed to provide a steady and uninterrupted flow of fluid to the pump inlet.
Characteristics of a Centrifugal Pump
Centrifugal pumps operate by converting mechanical energy from a motor into kinetic energy in the form of fluid velocity and pressure. These pumps are characterized by their ability to generate high flow rates with relatively low head pressures. The impeller within the pump creates a centrifugal force that propels the fluid outward, resulting in increased pressure and flow.

When selecting a centrifugal pump for a specific application, it is crucial to consider factors such as flow rate, head pressure, fluid properties, and system requirements. End suction centrifugal pumps are a common type of centrifugal pump that feature a single inlet and outlet connection. These pumps are suitable for a wide range of applications and are available in various sizes and configurations to meet specific needs.
Centrifugal Pumps Not Sucking
One of the most common issues faced with centrifugal pumps is the pump's inability to prime or "suck" fluid into the system. This can be caused by air leaks in the suction line, insufficient fluid level in the suction tank, or blockages in the suction piping. Proper maintenance and troubleshooting techniques are essential to ensure that the pump is operating efficiently and effectively.
How Does Centrifugal Pump Work
Centrifugal pumps work by utilizing the rotational motion of an impeller to impart energy to the fluid. As the impeller spins, it creates a centrifugal force that pushes the fluid outward from the center of the pump towards the discharge outlet. This action increases the fluid's velocity and pressure, allowing it to be pumped to the desired location. The efficiency of a centrifugal pump depends on factors such as impeller design, pump speed, and system configuration.
Centrifugal Pump Suction Piping Guidelines
Proper sizing and design of the suction piping are crucial for maintaining optimal pump performance. The suction piping should be sized so that the pressure drop through the line and fittings is minimized. Recommended pressure drop values for non-boiling liquids are typically in the range of 0.2 – 0.5 psi/100 ft (0.45 – 0.11 kPa/m), while for boiling liquids, the recommended pressure drop is lower, around 0.05 – 0.025 psi/100 ft (0.01 – 0.06 kPa/m). Ensuring that the suction piping is correctly sized and free from obstructions is essential for preventing cavitation and maintaining efficient pump operation.
