Pump manufacturers often supply performance curves at a specified speed. While this is useful when the pump only runs at that rated speed, performance changes when the pump has a Variable Frequency Drive (VFD). A VFD changes the shaft speed, which, in turn, changes the performance curves. If the manufacturer only supplied a curve at a sin...

The term transient cavitation is thrown around frequently when talking about the effects that transient events have on piping systems. It is widely and correctly understood to be something that can be harmful to pipes and pipe system components, but how to predict and calculate transient cavitation is not something that is as equally understood. In...

Veteran AFT software users are familiar with heritage products like AFT SteamCalc and AFT Chempak Viewer. Some have wondered where these products went. Although licenses to these products are no longer sold, these viewers are now integrated into the main applications for each of AFT's main products: AFT Fathom, AFT Arrow, AFT Impulse, and AFT ...

Eductors, also known as jet pumps, are a clever way to pump a liquid without any rotating equipment, motors, shafts, or electricity using only the momentum from a supply fluid. However, these interesting pumps can quickly become confusing especially when trying to define them in AFT Fathom. In this blog we will explore exactly how eductors work and...

Have you ever been working on an interesting project where you get into the zone by picking up so much momentum in the work you are doing? But then, all of a sudden you hit a brick wall in your progress and cannot help but feel the pain of all that momentum coming to a screeching halt? You are not alone, in fact, fluids experience something ve...
