Visualization of Gas-Liquid Flow Pattern in a Centrifugal Pump
The centrifugal pump is extensively used in the fields of petroleum, chemical industry, nuclear power, agriculture, etc. The bubble flow is an important flow pattern that exists in the working process of a centrifugal pump.

Paradigm Shift Towards Solar Powered Centrifugal Pumps
Ideally, a centrifugal pump should be operated at or near its best efficiency point (BEP) flow rate in order to minimize the life cycle costs. However, all centrifugal pumps have sweet spots beyond the BEP that will yield acceptable efficiency and reliability.

Centrifugal Pump Flow Operating Regions and Impact on Reliability
Ideally, a centrifugal pump should be operated at or near its best efficiency point (BEP) flow rate in order to minimize the life cycle costs. However, all centrifugal pumps have sweet spots beyond the BEP that will yield acceptable efficiency and reliability.

What is a Centrifugal Pump?
Every centrifugal pump includes an assembly of mechanical components that make operation of the pump possible.

How to Understand Net Positive Suction Head
The NPSH available to the pump should be more than what the pump requires. If there is not enough NPSHa, the pump will cavitate.

Selecting the Right Pump for Chemical Applications
There are many considerations when selecting the right pump for chemical applications. When working with materials such as corrosive or flammable chemicals, extra care should be taken to ensure that the product selected is suitable.

A Step-by-Step Approach to Pump Selection
Velocity of liquid in pipes ranges between 3 to 10 feet per second (ft/sec). If the velocity is too slow, the dirt, sludge or other contaminants can settle. If flow is too fast, abrasive wear will reduce the life of the pipe.

Back to Basics: Pump Types – End Suction Vs. Double Suction
There are often multiple pump types (Table 1) that can be selected for the same water application, with each pump type having its own strengths and weaknesses. This column tries to help guide the reader in the selection of the best pump type that will yield the greatest reliability and lowest life cycle cost for…

5 Must-Read Articles About Pump Efficiency
Efficiency is simply how well a machine can convert one form of energy to another. If one unit of energy is supplied to a machine and its output, in the same units of measure, is one-half unit, its efficiency is 50 percent.
