Examining Causes of Pump Vibration as Featured in HPAC Engineering

admin — Thu, 03 Dec 2009 18:53:30 +0000

Many vibration problems are a result of interactions among a system’s pump, motor, fluid, piping, and structure. This interactive relationship requires a systems approach to vibration analysis, rather than the investigation of individual components. This article discusses the cause of vibration, how is it measured and described, its limitations, and many other vibration related issues. Click here to learn more.

ESP-Plus: Spotlight on Pump Curves

admin — Thu, 03 Dec 2009 18:49:23 +0000

Not all pump selection programs are created equally. The algorithms used to select pumps and generate curves need to be very sophisticated. ESP-PLUS® uses a three curve interpolation method developed by ITT. Unlike some other pump selection programs on the market, you can be assured the results from ESP-PLUS are very accurate.
