Within each pump category, many subtypes have been developed to improve pump performance for different types of fluids. For instance, the most popular impeller pump is the centrifugal pump, with its curved vanes, while the regenerative turbine pump, shown in Figure 1, is another lesser-known variation.
A centrifugal pump containing two or more impellers is called a multistage centrifugal pump. The impellers may be mounted on the same shaft or on different shafts. At each stage, the fluid undergoes an increase in pressure and velocity, allowing for efficient pumping of various liquids in a wide range of industries.

3. **Versatility**: Centrifugal pumps can handle a wide range of liquids, including water, chemicals, oil, and wastewater, making them suitable for diverse industries.
4. **Energy Efficiency**: Centrifugal pumps are energy-efficient, consuming less power compared to other types of pumps.
Why Are Centrifugal Pumps Used?
Centrifugal pumps are widely used in various industries for several reasons:
1. **Versatility**: Centrifugal pumps can handle a wide range of liquids, making them suitable for applications in industries such as oil and gas, chemical processing, water treatment, and agriculture.
2. **Efficiency**: Centrifugal pumps are known for their high efficiency, resulting in cost savings and reduced energy consumption.
3. **Reliability**: Centrifugal pumps are reliable and have a long service life, providing continuous operation with minimal downtime.
4. **Low Maintenance**: Centrifugal pumps require minimal maintenance, reducing operational costs and downtime.
Centrifugal Pumps: How They Work
Centrifugal pumps operate based on the principle of centrifugal force. When the pump is in operation, the rotating impeller accelerates the liquid, creating a centrifugal force that pushes the liquid outward. This action increases the liquid's velocity and pressure, allowing it to be discharged through the pump outlet.
The key components of a centrifugal pump include the impeller, casing, and shaft. The impeller is responsible for imparting kinetic energy to the liquid, while the casing directs the flow of the liquid and converts kinetic energy into pressure energy. The shaft connects the impeller to the motor, facilitating the transfer of rotational energy.
Centrifugal Pump Types
There are several types of centrifugal pumps, each designed for specific applications:
1. **Single-Stage Centrifugal Pump**: This type of pump has a single impeller and is suitable for low to medium flow rate applications.
2. **Multistage Centrifugal Pump**: A multistage centrifugal pump contains two or more impellers, allowing for higher pressure and flow rates.
3. **Vertical Centrifugal Pump**: Vertical centrifugal pumps are designed for applications where space is limited, such as in wells or sumps.
4. **Horizontal Centrifugal Pump**: Horizontal centrifugal pumps are commonly used in industrial applications for their ease of installation and maintenance.

According to Reti, the first machine that could be characterized as a centrifugal pump was a mud lifting machine which appeared as early as 1475 in a treatise by the Italian
meridional shape of the impeller. In this paper, an innovative approach for design and optimization of pump impellers is presented which is based on so-called inverse design. This means that an optimal blade shape is determined by providing objective flow properties in terms of blade loading. In doing so, pump impellers with high efficiency factors
