Next, the centrifugal pump supplier will introduce how to select a centrifugal pump. The following chief factors affect the performance of a centrifugal pump and need to be considered while choosing a centrifugal pump: Working Fluid Viscosity. It can be defined as resistance to shear when energy is applied. In general, a centrifugal pump is .

A dead-head occurs when a centrifugal pump operates with no flow due to a line blockage or a closed discharge valve, causing a complete stop of fluid flow. When this happens, water is unable to exit and the same water continues to circulate, causing the temperature to rise. As the liquid reaches its boiling point and begins to vaporize, the .
Centrifugal pumps are essential equipment used in various industries to move fluids from one place to another. One of the key functions of a centrifugal pump is to increase the pressure of the fluid being pumped. In this article, we will delve into how centrifugal pumps achieve this, common problems associated with centrifugal pumps, the function of a centrifugal pump, and factors affecting the performance and pressure head of a centrifugal pump.
In the case of a positive displacement pump, only the pressure is determined by the system curve. The flow rate is a fixed value. Both are still created by the pump, but only one is “decided” by it. For a centrifugal pump,
Centrifugal Pump Pressure Increase
Centrifugal pumps work by converting mechanical energy from a motor into kinetic energy in the form of a rotating impeller. As the impeller spins at high speeds, it creates a centrifugal force that pushes the fluid outward. This action increases the fluid velocity and, consequently, the pressure of the fluid. The pressure increase is achieved by the conversion of kinetic energy into potential energy as the fluid moves through the pump.
Centrifugal Pump Problems
While centrifugal pumps are efficient and widely used, they can experience various problems that affect their performance. Common issues include cavitation, which occurs when the pressure of the fluid drops below its vapor pressure, leading to the formation of vapor bubbles that implode and cause damage to the pump components. Other problems include wear and tear of impeller blades, seal leakage, and motor issues.
Centrifugal Pump Function
The primary function of a centrifugal pump is to transport fluids by converting mechanical energy into kinetic energy. The pump consists of an impeller that rotates within a casing, creating a centrifugal force that pushes the fluid towards the outlet. As the fluid moves through the pump, its velocity increases, leading to a rise in pressure. Centrifugal pumps are used in various applications, including water supply, wastewater treatment, oil and gas industry, and chemical processing.
Flow Rate of Centrifugal Pump
The flow rate of a centrifugal pump is the volume of fluid that passes through the pump per unit of time. It is influenced by factors such as the speed of the impeller, the size of the pump, and the properties of the fluid being pumped. Increasing the speed of the impeller or the size of the pump can result in a higher flow rate. However, it is essential to consider the system's limitations and requirements to ensure optimal performance.
Centrifugal Pump Performance
The performance of a centrifugal pump is determined by various factors, including efficiency, head, and power consumption. Efficiency is a measure of how well the pump converts input power into useful work. Head refers to the pressure generated by the pump, which is crucial for overcoming resistance in the system. Power consumption indicates the amount of energy required to operate the pump efficiently. By optimizing these factors, the performance of a centrifugal pump can be enhanced.
Pressure Head for Centrifugal Pump
the main reason for using head instead of pressure to measure a centrifugal pump's energy is that the pressure from a pump will change if the specific gravity (weight) of the liquid changes, but …
The maximum pump head of a centrifugal pump is mainly determined by the outside diameter of the pump’s impeller and the shaft angular velocity – speed of the rotating shaft. The head will also change as the volumetric flow rate through the pump is increased. . First, we have to calculate the radial velocity of the flow at the outlet. From .
