Three Screw Pump – Here one gear receives power from the source, and this drives the other two gears. Four Screw Pump – This is, in general, a two-screw pump having two screws per each rotor. It has timing gears to drive the next one. Five Screw Pump – It is similar to that of five screw pumps whereas, in the place of 3 screws, this has 5.“Screw pump” configurations may include single screw/eccentric screw/progressive cavity, external bearing, timed twin screw pumps, small three screw pumps on lube oil .

Different types of centrifugal pumps are widely used in various industries worldwide. These pumps are classified based on the number of impellers, type of casing, orientation, and position.

It is one of the simple and exciting topics in fluid mechanics.What is the need for a pump? We require a pump to transmit water from a region of low pressure to a region of higher pressure. The centrifugal pump defines as a hydraulic machine that converts mechanical energy into hydraulic energyby means of a

Based on the Number of Impellers

# Single Stage Impeller

A single-stage centrifugal pump has only one impeller. It is commonly used for applications where low to moderate flow rates are required. The single impeller design simplifies the pump construction, making it cost-effective and easy to maintain.

# Multistage Impeller

Multistage centrifugal pumps have multiple impellers stacked in series within the same casing. This design allows for higher pressure and flow rates compared to single-stage pumps. Multistage pumps are often used in applications that require high pressure, such as boiler feed systems and high-pressure cleaning.

Centrifugal Pump Components and Functions

Centrifugal pumps consist of several key components that work together to facilitate the pumping process. These components include:

1. **Impeller**: The impeller is the rotating component of the pump that imparts energy to the fluid by spinning at high speeds. It is designed to convert the mechanical energy from the motor into kinetic energy in the fluid.

2. **Casing**: The casing is the outer shell of the pump that encloses the impeller and volute. It is designed to direct the flow of fluid through the pump and increase the velocity of the fluid as it passes through the impeller.

3. **Volute**: The volute is a curved section of the casing that helps to convert the kinetic energy of the fluid into pressure energy. It also helps to direct the flow of fluid from the impeller to the discharge outlet.

4. **Shaft**: The shaft connects the motor to the impeller and transmits the rotational energy from the motor to the impeller. It must be properly aligned and supported to ensure smooth operation of the pump.

5. **Bearings**: Bearings support the shaft and help reduce friction during operation. Proper lubrication and maintenance of bearings are essential to prevent premature wear and ensure the longevity of the pump.

6. **Seals**: Seals prevent leakage of fluid from the pump and help maintain the efficiency of the pumping system. Common types of seals used in centrifugal pumps include mechanical seals and gland packing.

Centrifugal Pump Selection Chart

When selecting a centrifugal pump for a specific application, various factors need to be considered, including:

- Flow rate requirements

- Total dynamic head

- Fluid properties

- Operating conditions

- Efficiency and reliability

A centrifugal pump selection chart can help engineers and operators choose the right pump for their needs based on these factors. By matching the pump performance curve with the system requirements, the most suitable pump can be selected to achieve optimal performance and efficiency.

Pump Impeller Size Chart

The size and design of the impeller play a crucial role in determining the performance of a centrifugal pump. A pump impeller size chart provides information on the dimensions, blade geometry, and material of construction for different impeller sizes. Proper selection of the impeller size is essential to ensure efficient fluid flow and pressure generation within the pump.

Centrifugal Pump Diagram with Parts

A centrifugal pump diagram with parts illustrates the internal components of the pump and their respective functions. This visual representation helps in understanding how the pump operates and how each part contributes to the overall pumping process. Common parts shown in the diagram include the impeller, casing, volute, shaft, bearings, and seals.

Centrifugal Pump How It Works

Centrifugal pumps work on the principle of centrifugal force to transport fluids from one location to another. When the impeller rotates, it creates a centrifugal force that pushes the fluid towards the outer edges of the impeller. As the fluid moves through the impeller, it gains kinetic energy and is discharged through the volute at a higher pressure.

Centrifugal Pump Drawing with Parts

A centrifugal pump drawing with parts provides a detailed technical illustration of the pump components and their arrangement within the pump housing. Engineers and maintenance personnel can use these drawings to identify and troubleshoot issues, perform maintenance tasks, and understand the overall construction of the pump.
