Pump casings play a crucial role in the operation of centrifugal pumps. They serve to seal off the inside of the pump to the atmosphere to prevent leakage and ensure efficient performance. The design and material of the casing can significantly impact the pump's overall efficiency and reliability. In this article, we will explore the various aspects of function casing centrifugal pumps, including types of centrifugal pump casings, major parts of centrifugal pumps, casing materials, and the differences between volute and circular casing pumps.
Casing surrounds the rotor and permits installation and removal of rotors. Casing provides structural support for the pump or a sturdy structural connection to the pump's support. Casing keeps the pump and its rotor well aligned when it is under the action of piping load conditions.
Types of Centrifugal Pump Casings
Centrifugal pumps can have different types of casings, each designed to suit specific applications and operating conditions. Some common types of centrifugal pump casings include:
1. Volute Casing: The volute casing is the most common type of casing used in centrifugal pumps. It features a spiral-shaped design that helps to convert kinetic energy into pressure. The volute casing is known for its efficiency and is widely used in various industries.
2. Circular Casing: Circular casings are another type of casing used in centrifugal pumps. They have a simple circular design and are often used in smaller pumps or applications where space is limited. Circular casings are easy to manufacture and maintain.
3. Split Casing: Split casings are designed to be opened along the horizontal or vertical axis, allowing for easy access to the pump internals for maintenance and repairs. Split casings are commonly used in large industrial pumps where downtime must be minimized.
4. Axial Split Casing: Axial split casings are similar to split casings but are split along the pump's axis. This design allows for easy access to the impeller and other internal components for maintenance.
Centrifugal Pump Drawing with Parts
A typical centrifugal pump consists of several key parts, each playing a vital role in the pump's operation. Here is a centrifugal pump drawing with parts:
1. Impeller: The impeller is the rotating component of the pump that imparts energy to the fluid by spinning at high speeds. It is typically made of metal or plastic and is designed to efficiently move the fluid through the pump.
2. Casing: The casing is the outer shell of the pump that encloses the impeller and other internal components. It is designed to direct the flow of fluid and prevent leakage.
3. Shaft: The shaft connects the impeller to the motor and transmits the rotational energy from the motor to the impeller.
4. Bearings: Bearings support the shaft and allow it to rotate smoothly. They are crucial for reducing friction and ensuring the pump operates efficiently.
5. Seals: Seals are used to prevent leakage of fluid from the pump. They help maintain the integrity of the pump's casing and protect internal components from damage.
Single Stage Centrifugal Pump Diagram
A single-stage centrifugal pump is a type of pump that has only one impeller. Here is a diagram of a single-stage centrifugal pump:

In a single-stage centrifugal pump, the fluid enters the pump through the suction port and is directed to the impeller. The impeller then imparts energy to the fluid, increasing its velocity and pressure. The fluid is then discharged through the pump's outlet port.

The casing is designed to direct the flow of fluid through the pump and prevent leakage. It is typically made of metal or plastic and is carefully designed to optimize the pump's performance.
Major Parts of Centrifugal Pump
In addition to the impeller and casing, centrifugal pumps have several other major parts that are essential for their operation. Some of these parts include:
1. Suction Pipe: The suction pipe is used to draw fluid into the pump from the source. It is crucial for ensuring a steady flow of fluid to the impeller.
2. Discharge Pipe: The discharge pipe is used to channel the pressurized fluid out of the pump and into the desired system or application.
3. Motor: The motor provides the power needed to drive the pump and rotate the impeller. It is typically connected to the pump shaft via a coupling.
4. Coupling: The coupling connects the motor to the pump shaft and allows for the transfer of power from the motor to the impeller.
Centrifugal Pump Casing Material
The material used for the centrifugal pump casing can vary depending on the application and the type of fluid being pumped. Some common materials used for pump casings include:
1. Cast Iron: Cast iron is a popular choice for pump casings due to its durability and corrosion resistance. It is suitable for a wide range of applications and is relatively easy to manufacture.
2. Stainless Steel: Stainless steel is often used in applications where corrosion resistance is crucial. It is highly durable and can withstand harsh operating conditions.
3. Bronze: Bronze is commonly used in seawater applications due to its excellent corrosion resistance. It is also known for its high strength and durability.
4. Plastic: Some centrifugal pumps use plastic casings, such as polypropylene or PVC, for applications where corrosion resistance and chemical compatibility are essential.
Volute vs. Circular Casing Pump
The choice between a volute and circular casing pump depends on the specific requirements of the application. Here are some key differences between the two types of casings:
1. Volute Casing:
- Volute casings are more efficient at converting kinetic energy into pressure due to their spiral design.
- They are commonly used in high-flow, low-head applications.
- Volute casings are more complex in design and may require more maintenance.
2. Circular Casing:
- Circular casings are simpler in design and are easier to manufacture and maintain.
- They are often used in smaller pumps or applications where space is limited.
- Circular casings are generally less efficient than volute casings but can still be effective for certain applications.
Impeller Pump vs. Centrifugal Pump
While impeller pumps and centrifugal pumps both use impellers to move fluids, there are some key differences between the two types of pumps:
1. Impeller Pump:
- An impeller pump is a type of pump that consists solely of an impeller and a casing.
- It is typically used for low-flow, high-pressure applications.
- Impeller pumps are simple in design and are often used in applications where space is limited.
2. Centrifugal Pump:
- A centrifugal pump is a more complex pump that consists of multiple components, including an impeller, casing, shaft, and bearings.
- Centrifugal pumps are suitable for a wide range of flow and pressure requirements.
