centrifugal pump selection procedure|centrifugal pump selection chart : dealer Engineers are expected to select a pump that is appropriate for the application and of the correct size (pump model and impeller diameter) to handle the design conditions. This course will help … Causes of cavitation in centrifugal pumps . Cavitation is a leading cause of pump failure. Since cavitation can result from excessively low pressure at the pump inlet, it can be prevented by ensuring the pressure at the suction end of the pump remains sufficiently above the liquid’s vapor pressure. Factors leading to low inlet pressure:

Cavitation is a common issue in pumps, and it can cause significant damage if not appropriately addressed. This article explains cavitation in centrifugal and positive displacement pumps, its causes and effects, and .
When it comes to selecting a centrifugal pump for a specific application, there are several factors to consider to ensure optimal performance and efficiency. The selection procedure involves analyzing various parameters such as process flow requirements, system heads, pump curves, impeller sizes, and pump types. In this article, we will discuss the step-by-step centrifugal pump selection procedure to help you make an informed decision for your pumping needs.
In this comprehensive guide, we’ll delve into the intricacies of pump selection, exploring the fundamental principles, assessing application requirements, matching pump types to applications, and evaluating crucial factors that influence the decision.
Centrifugal Pump Coverage Chart
A centrifugal pump coverage chart provides a graphical representation of the pump's performance characteristics, including flow rate, head, efficiency, and power requirements. By referring to the pump coverage chart, you can determine the operating range of the pump and select the most suitable model for your application based on the required flow rate and head.
Centrifugal Pump Catalogue
A centrifugal pump catalogue contains detailed information about various pump models offered by a manufacturer. It includes specifications, performance data, dimensions, materials of construction, and other relevant details that can help you compare different pump options and choose the one that best fits your requirements.
Centrifugal Pump Selection Chart
A centrifugal pump selection chart is a tool that helps in determining the appropriate pump size based on the system's flow rate and head requirements. By plotting the system curve against the pump curve on the selection chart, you can identify the operating point where the pump will deliver the desired flow rate at the required head.
Centrifugal Pump Size Chart
A centrifugal pump size chart provides information on the available pump sizes within a specific model range. It includes data on the pump's capacity, head range, motor power, and other technical specifications. By referring to the size chart, you can narrow down your options and select the pump size that matches your system requirements.
Centrifugal Pump Impeller Size Chart
The impeller size plays a crucial role in determining the pump's performance characteristics, such as flow rate, head, and efficiency. A centrifugal pump impeller size chart helps in selecting the appropriate impeller diameter based on the desired operating conditions and performance goals. Different impeller sizes can be chosen to achieve specific flow and head requirements.
Different Types of Centrifugal Pumps
There are several types of centrifugal pumps available, each designed for specific applications and operating conditions. Some common types include end-suction pumps, inline pumps, multistage pumps, self-priming pumps, and submersible pumps. Understanding the differences between these pump types and their respective advantages can help you choose the most suitable option for your pumping system.
Centrifugal Pump Selection Guide
To select a pump to operate in its POR, first identify the maximum and minimum process flow requirements and the corresponding system heads. System curve (s) for the …
Centrifugal Pump Characteristic Curve. For a given centrifugal pump operating at a constant speed, the flow rate through the pump is dependent upon the differential pressure or head developed by the pump. The lower the pump .
