How does a split case pump work? What is the difference between split case and end suction pump?

What Is Horizontal Split Case Pumps

Horizontal split case pumps are a type of centrifugal pump that is designed with a horizontally split casing. This design allows for easy access to the internal components of the pump, making maintenance and repairs more convenient. 

These pumps are commonly used in applications that require high flow rates and moderate to high head, such as water supply, irrigation, HVAC systems, and industrial processes. The split case design allows for efficient handling of large volumes of liquid, and the horizontal orientation makes them suitable for installation in a variety of settings.

Horizontal split case pumps are known for their reliability, ease of maintenance, and long service life. They are available in a range of sizes and configurations to meet the specific requirements of different applications.

How Does a Split Case Centrifugal Pump Work?

A split case pump, also known as a double suction pump, operates using the principles of centrifugal force to move fluid. Here's a brief overview of how a split case pump works: 

1. Fluid enters the pump through the suction nozzle, which is located at the center of the pump casing. The split case design allows for fluid to enter from both sides of the impeller, hence the term "double suction." 

2. As the impeller rotates, it imparts kinetic energy to the fluid, causing it to move radially outward. This creates a low-pressure area at the center of the impeller, drawing more fluid into the pump. 

3. The fluid is then directed to the outer edges of the impeller, where it is discharged at a higher pressure through the discharge nozzle. 

4. The split case design ensures that the hydraulic forces acting on the impeller are balanced, resulting in reduced axial thrust and improved bearing life.

5. The pump casing is designed to efficiently guide the flow of fluid through the impeller, minimizing turbulence and energy losses.

What Is The Advantage Of a Horizontal Split Casing?

The advantage of a horizontal split casing in pumps is easy access to internal components for maintenance and repair. The split casing design allows for straightforward disassembly and reassembly, making it easier for technicians to service the pump without having to remove the entire casing. This can result in significant time and cost savings during maintenance activities. 

The horizontal split casing design often allows for better access to the impeller and other internal components, facilitating inspection and maintenance procedures. This can contribute to improved pump reliability, reduced downtime, and overall operational efficiency. 

Horizontal Split Casing design is friendly to inspect and replace wearing parts, such as bearings and seals, which can help extend the service life of the pump and reduce the total cost of ownership.

End Suction Vs. Horizontal Split-Case Pumps

End suction pumps and horizontal split-case pumps are both types of centrifugal pumps commonly used in industrial, commercial, and municipal applications. Here's a comparison of the two types:

End Suction Pumps:

- These pumps have a single suction impeller and a casing that is typically mounted vertically.

- They are known for their compact design and ease of installation, making them suitable for a wide range of applications.

- End suction pumps are often used in HVAC systems, water supply, and general industrial applications where moderate flow rates and head are required.

End suction centrifugal pumps get their name from the pathway the water takes to enter the pump. Typically the water enters one side of the impeller, and on horizontal end suction pumps, this appears to enter “the end” of the pump. Unlike the Split casing type the suction pipe and motor or engine are all parallel, eliminating the concern about pump rotation or orientation in the mechanical room. Since water is entering one side of the impeller, you lose the ability to have bearings on both sides of the impeller. Bearing support will be either from the motor itself, or from the pump power frame. This prevents the use of this type of pump on large water flow applications.

Horizontal Split-Case Pumps:

- These pumps have a horizontally split casing, which allows for easy access to internal components for maintenance and repairs.

- They are designed to handle high flow rates and moderate to high head applications, such as water supply, irrigation, and industrial processes.

- Horizontal split-case pumps are known for their reliability, efficiency, and long service life.

Model No:XBC-ASN 

Precision balancing of all factors in the design of ASN horizontal split case fire pump provide mechanical dependability, efficient operation and minimal maintenance. Simplicity of design ensures long efficient unit life, reduced maintenance costs and minimum power consumption.Split case fire pumps are specifically designed and tested for fire service application around the world including: Office buildings, hospitals, airports, manufacturing facilities, warehouses, power stations, oil and gas industry, schools.

End suction pumps are more compact and versatile, suitable for moderate-duty applications, while horizontal split-case pumps are designed for heavy-duty applications requiring high flow rates and head, with the added benefit of easy maintenance access due to their split casing design. The choice between the two types depends on the specific requirements of the application.
