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… more...
What is a Centrifugal Pump? - Every centrifugal pump includes an assembly of mechanical components that make operation of the pump possible. more...
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. more...
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. more...
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… more...
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… more...
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,… more...
How Centrifugal Pumps Work - A centrifugal pump is a type of rotodynamic pump that uses bladed impellers with essentially a radial outlet to transfer rotational mechanical energy to the fluid primarily by increasing the fluid kinetic energy (angular momentum) and increasing… more...
Characteristics of Centrifugal Pumps - A centrifugal pump converts driver energy to kinetic energy in a liquid by accelerating the fluid to the outer rim of an impeller. more...- Pumping Solids In Chemical Processing Applications - Centrifugal pumps featuring a stainless steel vortex impeller provide an excellent and well-proven solution for solids in chemical processing applications. more...
