Process plant operators continuously face the pressure of having to increase productivity by improving equipment reliability and plant availability, a goal seemingly at odds with the everyday realities of decreased operating budgets, rising energy costs and increasing operations costs. And, when it comes to energy consumption and maintenance costs, chemical process pumps are possibly the most notorious...

When automating fluid handling processes, it is critical to ensure that you are using the best type of pump for the process, and to understand how to control the type of pump you are using. The two major classes of process pumps — centrifugal and rotary positive displacement — require completely different control techniques. It is important to understand each pump type’s limitations, and...

To unearth the fundamental causes of vibration-related pump troubles, pump end-users and original equipment manufacturers (OEMs) typically have relied on a concise array of vibration field-test parameters. Conventional trial-and-error vibration troubleshooting methods often fail to achieve the longterm, trouble-free pump operation sought, yet they can be time-consuming and increasingly costly to apply...

Interest in energy efficiency is not a fad. The economics of industrial production, the limitations of global energy supply and the realities of environmental conservation will be enduring themes for decades, if not the millennia. As energy costs increase, pump manufacturers respond with an understanding of the importance of making equipment more efficient at saving energy. Traditional methods of...
