Researches have been devoted to the axial thrust acting on centrifugal pumps, finding that the axial thrust could reach a high order of magnitude (Childs, 1991, Takamine et al., 2021).Although plenty of theoretical formulas have been advanced for evaluating the axial thrust of pumps, a deviation exists between the calculation results and the measured axial thrust .
A centrifugal pump is a mechanical device that moves fluid by transferring rotational energy from one or more impellers. This type of pump is widely used in various industries to transport liquids such as water, chemicals, oil, and other fluids. Centrifugal pumps are known for their efficiency, reliability, and ease of maintenance, making them a popular choice for many applications.
The Centrifugal pumpis working based on the centrifugal force and the name follows the same. Fluid enters into the pumps, gets the energy from the centrifugal force of the impeller, and raised its velocity and pressure. Due to this pressure, the liquid is transferred from one place to another. See more
Centrifugal Pump Size Chart
Centrifugal pumps come in a wide range of sizes to accommodate different flow rates and pressure requirements. The size of a centrifugal pump is typically determined by the diameter of the impeller and the design of the pump casing. Larger pumps are capable of handling higher flow rates and pressures, while smaller pumps are more suitable for lower flow applications. Here is a general centrifugal pump size chart:
| Pump Size | Flow Rate (GPM) | Pressure (PSI) |
|-----------|------------------|---------------|
| 1 inch | 0-50 | 0-50 |
| 2 inch | 50-200 | 50-150 |
| 3 inch | 200-500 | 100-200 |
| 4 inch | 500-1000 | 150-250 |
| 6 inch | 1000-3000 | 200-300 |
Centrifugal Pump Diagram and Explanation
A centrifugal pump consists of several key components, including the impeller, casing, shaft, bearings, and seals. The impeller is the rotating component that imparts energy to the fluid, causing it to move through the pump. The casing surrounds the impeller and directs the flow of fluid through the pump. The shaft connects the impeller to the motor, while the bearings support the shaft and allow it to rotate smoothly. Seals are used to prevent leaks and maintain the efficiency of the pump.
Centrifugal Pump Selection Chart
When selecting a centrifugal pump for a specific application, several factors must be considered, including the flow rate, pressure requirements, fluid properties, and operating conditions. A centrifugal pump selection chart can help engineers and designers choose the right pump for their needs based on these factors. Factors such as pump efficiency, NPSH (Net Positive Suction Head) requirements, and material compatibility should also be taken into account during the selection process.
Different Types of Centrifugal Pumps
There are several different types of centrifugal pumps, each designed for specific applications and operating conditions. Some common types of centrifugal pumps include:
1. **End-Suction Centrifugal Pumps**: These pumps have a single impeller and are suitable for general-purpose applications.
2. **Split-Case Centrifugal Pumps**: These pumps have a split casing that allows for easy maintenance and repair.
3. **Vertical Multistage Centrifugal Pumps**: These pumps are designed for high-pressure applications and can handle a wide range of flow rates.
4. **Self-Priming Centrifugal Pumps**: These pumps are designed to eliminate the need for manual priming and are ideal for applications where the suction line may be prone to air pockets.
Characteristics of Centrifugal Pump
Centrifugal pumps have several key characteristics that make them suitable for a wide range of applications. Some of the main characteristics of centrifugal pumps include:
1. **High Efficiency**: Centrifugal pumps are known for their high efficiency, which helps reduce energy consumption and operating costs.
2. **Simple Design**: Centrifugal pumps have a simple design with fewer moving parts, making them easy to maintain and repair.
3. **Wide Range of Flow Rates**: Centrifugal pumps can handle a wide range of flow rates, making them versatile for different applications.
4. **Quiet Operation**: Centrifugal pumps operate quietly compared to other types of pumps, making them suitable for indoor applications.

Centrifugal Pumps: How They Work
The main parts of the Centrifugal Pump are: 1. Impeller 2. Casing 3. Backplate 4. Suction & Discharge Nozzles 5. Suction pipe 6. A foot valve 7. Strainer 8. Suction nozzle or suction
Multistage pump has several water impellers (turbines) mounted on a shaft. they work in series, that is to say, the first stage sucks the water, raises the pressure and passes it to the other stage, which raises the pressure again, and so on; that is to say they are of great pressure. (251.7 KB)
