One of the most common phenomena that can lead to damaged centrifugal pumps is cavitation. When your centrifugal pump is cavitating, it can lead to premature seal, bearing or other part failures. In this Centrifugal Pump Minute, we break down how to identify when your centrifugal pump is cavitating and how you can prevent it through consistent pump monitoring

A leaking ANSI centrifugal pump can create costly, time-consuming repairs and potentially hazardous working conditions, making proper sealing techniques crucial in pump set-up and maintenance. No matter the type, your pump’s shaft seals should be inspected and replaced regularly as part of essential centrifugal pump maintenance. In this Centrifugal Pump Minute, we discuss the importance of shaft seals and the options available for your ANSI centrifugal pump.

Need to understand how to read a centrifugal pump performance curve? Looking to learn about the differences between multiple impeller designs? Ever been curious about the history of centrifugal pumps? You’re in luck! Check out this comprehensive centrifugal pump guide.

In an ideal pumping scenario, your pump will always be located beneath the fluid level, allowing gravity to easily feed the fluid into the pump, thus completing the priming process. However, when an application calls for the pump to be located above the liquid level, which of these is a more robust and reliable solution: a) a self-priming centrifugal pump or b.) an end suction pump with a check valve? For the answer, check out our latest Centrifugal Pump Minute.

Why is centrifugal pump inspection so important? Simple: by following a centrifugal pump inspection process, you can help ensure safe and reliable pump performance. But what does this process involve? Read our Centrifugal Pump Minute for answers.

One of the primary causes of centrifugal pump vibration is misalignment, but this can be controlled by monitoring, and – if necessary – realigning the pump and motor shafts. In fact, not only is pump alignment a critical factor in eliminating pump vibration, but it can also help eliminate other pump problems and avoid total pump failure. In this Centrifugal Pump Minute, we provide the steps pump operators should follow to ensure both the pump and motor shafts are aligned.

While smooth centrifugal pump performance is the goal of every operation, occasionally, centrifugal pumps can develop issues that lead to costly downtimes. This includes centrifugal pump vibration, which is one of the clearest signs there’s a problem in the pump system. So, what are the keys to solving vibration and minimizing its hazards? Find out by reading the latest Centrifugal Pump Minute.

After 70 years in the pump industry, we’ve seen a thing or two when it comes to centrifugal pump operations, including common pump problems. That’s why we’ve developed this new troubleshooting guide, which describes some of the common pump issues your operation may encounter, their likely causes, and what to do about them.

Why is total dynamic head relevant when assessing centrifugal pump performance in the field? Read our newest Centrifugal Pump Minute to discover the importance of calculating total dynamic head, and how it can help centrifugal pump operators understand the proper sizing and scale for a pumping application.

Maintaining your Griswold® 811 ANSI Series Centrifugal Pumps is a simplified process thanks to their advanced engineering. Installing or replacing the seals is a particularly crucial part of basic maintenance to avoid fluid leaks, ruptures and other safety hazards. To help make the installation process easier, this Centrifugal Pump Minute provides a quick and handy guide for installing either a cartridge or component-type seal.

What is a centrifugal pump's best efficiency point (BEP), and what are the advantages of operating at the BEP? For answers, check out our latest Centrifugal Pump Minute, which illustrates how calculating and operating your centrifugal pump at its BEP can help optimize system performance.
