This manual covers the installation, operation, and maintenance of Patterson double suction centrifugal pumps. These pumps are designed to handle large flows of water and other liquids in various industrial applications. In this article, we will explore the features and advantages of double suction centrifugal pumps, as well as provide insights into their operation and maintenance.
This manual covers the installation, operation and maintenance of Patterson Pump horizontal split case pumps. The pump is a centrifugal, single stage, double suction type. When properly
Single Suction vs. Double Impeller
One of the key differences between single suction and double suction centrifugal pumps lies in the design of the impeller. Single suction pumps have an impeller that draws liquid from only one side, while double suction pumps have impellers that draw liquid from both sides. This design feature allows double suction pumps to achieve higher efficiency and lower NPSH requirements compared to single suction pumps.
Single Stage Double Suction Pump
A single stage double suction pump is a type of centrifugal pump that has a double suction impeller and a single stage design. These pumps are commonly used in applications where high flow rates are required, such as water supply systems, HVAC systems, and irrigation systems. The double suction design helps to balance hydraulic forces and reduce axial thrust, resulting in smoother operation and longer pump life.
Double Impeller Centrifugal Pump
Double impeller centrifugal pumps are designed with two impellers mounted on a common shaft. This design allows for higher flow rates and increased efficiency compared to single impeller pumps. The use of two impellers also helps to balance hydraulic forces and reduce axial thrust, resulting in improved pump performance and reliability.
Double Suction Pump Diagram
A double suction pump diagram typically shows the internal components of the pump, including the impellers, volute casing, shaft, and bearings. The diagram illustrates how the double suction impellers draw liquid from both sides and discharge it through a single outlet. Understanding the components and flow path of a double suction pump is essential for proper installation and maintenance.
Horizontal Split Case Pump Drawing
Horizontal split case pumps are a common type of centrifugal pump that features a horizontally split casing. This design allows for easy access to the internal components for maintenance and repair. A horizontal split case pump drawing provides a visual representation of the pump's layout, including the impeller, casing, shaft, and bearings. Properly interpreting the drawing is crucial for ensuring the correct assembly and operation of the pump.
Double Suction Split Case Pumps
Double suction split case pumps are a specific type of centrifugal pump that combines the features of double suction impellers and a horizontally split casing. These pumps are commonly used in applications where high flow rates and efficiency are required. The double suction design helps to reduce axial thrust and improve hydraulic balance, resulting in smoother operation and longer pump life.
Single Suction Centrifugal Pumps
Single suction centrifugal pumps have an impeller that draws liquid from only one side, unlike double suction pumps. While single suction pumps are simpler in design, they may have higher NPSH requirements and lower efficiency compared to double suction pumps. Single suction centrifugal pumps are suitable for applications with moderate flow rates and pressure requirements.

The next curve is the NPSH required curve. Net positive suction head at pump suction is necessary to prevent cavitation in the pump. From the curve, you can see that the NPSH requirement will increase with a higher flow rate. This is like more liquid with a higher . See more
