Discharge Cavitation: Discharge cavitation occurs when the centrifugal pump’s pressure is too high or loses 90% of its efficiency. Under this condition, the fluid cannot easily flow out of the pump. Instead, it moves inside the working chamber at high speeds, causing cavities to form. The easiest way to identify discharge cavitation is to .

When it comes to selecting the right centrifugal pump for your application, proper sizing is crucial to ensure optimal performance and efficiency. A centrifugal pump sizing chart, centrifugal pump coverage chart, centrifugal pump impeller size chart, and centrifugal pump selection chart are essential tools to help you determine the most suitable pump for your specific needs. In this article, we will explore the various charts and steps involved in centrifugal pump sizing to guide you through the process effectively.

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 pump impellers as to their type and proportions.

Centrifugal Pump Sizing Chart

A centrifugal pump sizing chart provides valuable information on the performance characteristics of different pump models. These charts typically include data such as flow rate, head capacity, efficiency, and power requirements for various pump sizes. By referring to a centrifugal pump sizing chart, you can compare different pump options and select the one that best meets your system requirements.

Centrifugal Pump Coverage Chart

A centrifugal pump coverage chart outlines the operating range of a pump in terms of flow rate and head capacity. This chart helps you determine whether a specific pump can deliver the required flow and pressure for your application. By referencing a centrifugal pump coverage chart, you can ensure that the selected pump will operate efficiently within the specified range.

Centrifugal Pump Impeller Size Chart

The impeller size plays a critical role in the performance of a centrifugal pump. A centrifugal pump impeller size chart provides information on the diameter and type of impellers available for different pump models. Selecting the right impeller size is essential to achieve the desired flow rate and head capacity. By consulting a centrifugal pump impeller size chart, you can make an informed decision on the most suitable impeller for your application.

Centrifugal Pump Selection Chart

A centrifugal pump selection chart offers a comprehensive overview of various pump models, their specifications, and performance characteristics. This chart allows you to compare different pumps based on factors such as flow rate, head capacity, efficiency, and power requirements. By utilizing a centrifugal pump selection chart, you can identify the optimal pump for your specific needs and operating conditions.

Pump Sizing Step by Calculation

The process of sizing a centrifugal pump involves several calculations to determine the pump's performance under different operating conditions. By following a systematic approach, you can accurately size the pump to ensure reliable and efficient operation. The steps involved in pump sizing by calculation may include determining the required flow rate, calculating the total dynamic head, selecting the appropriate pump model, and verifying the power requirements.

How to Select Centrifugal Pump
