Centrifugal pumps play a pivotal role on ships, known for their reliability. These marine pumps are essential for cooling systems to regulate engine temperatures, adjusting .
Centrifugal pumps are widely used in various industries for transferring fluids from one place to another. Proper selection and sizing of centrifugal pumps are crucial to ensure efficient operation and optimal performance. In this presentation, we will discuss the key factors to consider when sizing and selecting centrifugal pumps, including centrifugal pump sizing chart, coverage chart, impeller size chart, selection chart, pump sizing calculation steps, and pump type selection criteria.
Pump Efficiency is the ratio of BHP and WHP. Best Efficiency Point (BEP) is the capacity at maximum impeller diameter at which the efficiency is highest. Specific speed (Ns) is a non-dimensional design index that identifies the geometric similarity of pumps. It is used to classify
Centrifugal Pump Sizing Chart
A centrifugal pump sizing chart provides a quick reference guide for selecting the right pump size based on the flow rate and head requirements of the system. The chart typically includes various pump sizes with corresponding performance curves, showing the pump's efficiency, power consumption, and operating range. By referring to the sizing chart, engineers can easily identify the most suitable pump size for their application.
Centrifugal Pump Coverage Chart
The centrifugal pump coverage chart illustrates the pump's performance characteristics under different operating conditions. It shows the pump's efficiency, NPSH requirements, and flow rates at various heads. By analyzing the coverage chart, engineers can determine the pump's operating range and ensure that it can meet the system's requirements without exceeding its limitations.
Centrifugal Pump Impeller Size Chart
The impeller size plays a critical role in determining the pump's performance and efficiency. The centrifugal pump impeller size chart provides information on the available impeller sizes for a specific pump model. Engineers can select the appropriate impeller size based on the desired flow rate, head, and efficiency requirements. Choosing the right impeller size is essential for achieving optimal pump performance and minimizing energy consumption.
Centrifugal Pump Selection Chart
A centrifugal pump selection chart helps engineers compare different pump models based on their performance characteristics. The chart typically includes key parameters such as flow rate, head, efficiency, power consumption, and NPSH requirements for each pump model. By referring to the selection chart, engineers can evaluate multiple pump options and select the most suitable one for their application based on performance and cost considerations.
Pump Sizing Step by Calculation
Proper pump sizing involves calculating the required flow rate, total dynamic head, and system curve to determine the pump's operating point. The pump sizing calculation steps typically include:
1. Determine the system flow rate and head requirements.
2. Calculate the total dynamic head including friction losses, elevation changes, and system pressure requirements.
3. Plot the system curve to represent the relationship between flow rate and head.
4. Select a pump that can operate at the intersection of the system curve and the pump performance curve.
By following these steps, engineers can accurately size the centrifugal pump to meet the system's hydraulic demands and ensure efficient operation.
How to Select Centrifugal Pump
When selecting a centrifugal pump, engineers should consider various factors such as:
- Flow rate requirements
- Total dynamic head
- Fluid properties
- NPSH available
- Pump efficiency
- Operating conditions (temperature, pressure, etc.)
- System compatibility
- Maintenance requirements
- Cost considerations
By evaluating these factors and referring to centrifugal pump sizing charts and selection criteria, engineers can choose the most suitable pump for their specific application.

This document discusses pump selection and applications. It begins by outlining the chapter, which covers introductory concepts in pump selection, parameters to consider, types of pumps including positive …
Centrifugal pump parking precautions: (1) If the centrifugal pump stops the motor first and then closes the outlet valve, the high pressure liquid in the extrusion pipe may be reversed into the pump, causing the impeller to reverse at a high speed, resulting in damage. (2) If the pump is not used for a long time or the ambient temperature is .
