The static suction head on the other hand is the difference in elevation between the suction liquid level and the pump centreline. If the static suction head has a negative value because the suction liquid level is below the pump centreline, it is often referred of as static suction lift. If either the suction or discharge liquid level is under .

Centrifugal pumps are widely used in various industries for fluid transfer and circulation. They are simple in design and operation, making them popular for many applications. A simple centrifugal pump consists of several key parts that work together to achieve the desired pumping action. In this article, we will explore the different parts of a centrifugal pump and how they function.

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

Parts of a Centrifugal Pump

1. Shaft and Shaft Sleeve: The shaft is a critical component of the centrifugal pump as it connects the motor to the impeller. It transmits the rotational energy from the motor to the impeller, causing it to spin and create the pumping action. A shaft sleeve is often used to protect the shaft from wear and corrosion.

2. Impeller: The impeller is a rotating component of the centrifugal pump that is responsible for generating the centrifugal force to move the fluid. It is typically made of metal or plastic and has vanes that push the fluid outward, creating a flow towards the discharge.

3. Casing: The casing is the outer shell of the centrifugal pump that encloses the impeller and other internal components. It is designed to contain the fluid being pumped and direct it towards the discharge. The shape and size of the casing can affect the performance of the pump.

4. Suction Pipe: The suction pipe is the inlet through which the fluid enters the centrifugal pump. It is connected to the casing and allows the pump to draw in the fluid from the source. Proper sizing and placement of the suction pipe are essential for efficient operation.

5. Delivery Pipe: The delivery pipe is the outlet through which the pumped fluid is discharged. It is connected to the casing and directs the fluid away from the pump to the desired location. The size and length of the delivery pipe can impact the pressure and flow rate of the pump.

Centrifugal Pump Basics

Centrifugal pumps work on the principle of centrifugal force, where the rotation of the impeller creates a high-velocity flow that converts into pressure energy. This pressure energy is used to move the fluid through the pump and into the system. The efficiency of a centrifugal pump depends on various factors, including the design of the impeller, casing, and piping system.

To better understand how a centrifugal pump works, let's look at a simple diagram and explanation of its operation:

1. The motor drives the shaft, which in turn rotates the impeller inside the casing.

2. As the impeller spins, it creates a low-pressure zone at the center, causing the fluid to be drawn into the pump through the suction pipe.

3. The fluid is then accelerated by the rotating impeller and pushed towards the outer edge of the casing.

4. The high-velocity flow exits the impeller and enters the delivery pipe, where it is discharged to the desired location.

Centrifugal Pump vs Peripheral Pump

While centrifugal pumps are widely used for their simplicity and efficiency, peripheral pumps offer some distinct advantages in certain applications. Peripheral pumps, also known as regenerative pumps, have a different impeller design that allows for higher pressures at lower flow rates. They are often used in systems where high pressure is required, such as in domestic water supply systems.

Centrifugal Pump Inlet and Outlet

The inlet and outlet of a centrifugal pump play a crucial role in its performance. Proper positioning and sizing of the inlet are essential to ensure that the pump can draw in the fluid efficiently. The outlet, on the other hand, determines the flow rate and pressure of the pumped fluid. It is important to consider the size and configuration of both the inlet and outlet when designing a centrifugal pump system.

Centrifugal Pumps in Detail

Centrifugal pumps are versatile and reliable machines that are used in a wide range of industries, including agriculture, manufacturing, and water treatment. They are capable of handling various types of fluids, from water to chemicals, making them essential for many processes. Understanding the different parts and functions of a centrifugal pump is key to maximizing its performance and efficiency.

A self-priming centrifugal pump has two phases of operation: priming mode and pumping mode. In its priming mode, the pump essentially acts as a liquid-ring pump. The rotating impeller generates a vacuum at the impeller’s ‘eye’ which .
