We are now three blogs into our series on Variable Speed Pump Control and we are going to hit the pause button and review some fundamentals. If sequentially that seems like a strange thing to do, there is a method to our madness...
Read MoreIn our last blog, we left you with two new terms, “Control Curve” and “Control Area,” indicating that any variable speed control strategy will be based on one or the other. What are these strategies and how do they differ? Before we pull out the curves, schematics and calculations, let’s start with a simple analogy...
Read MoreToday we begin a series of blogs exploring modern variable speed pump control. While we have written about variable speeding pumping in the past, we believe that the increasing presence of variable speed systems, along with the rapid evolution of control options, warrants a comprehensive look at variable speed pump control as a...
Read MoreAs we conclude this series on how to select a centrifugal pump for your hydronic applications we want to leave you with the following “best practices” for overall safe, efficient, and long lasting performance...
Read MoreThere are times when slightly more capacity or a little more safety factor is warranted in a pump selection. Often we are asked about increasing the speed of the motor above the nameplate rated RPM. There are several things to examine....
