The differences between smart pumps and conventional pumps impact certain parts of their curves. In this blog post, we will review the elements of a smart pump curve, using Xylem’s B&G e-1510X-3BD ….
Read MorePerhaps you’ve heard about mandates for higher energy efficiency and the innovations that have emerged to meet these requirements. Integrated control functionality for some HVAC equipment is among these innovations. Fan manufacturers were the first….
Read MoreIn Part 2 of our How to Build a Centrifugal Pump Curve series, we added five head/capacity curves to the e-1510 4BD pump curve we are building. These curves reflect the tested performance of pumps with various-size impellers. Now, it's time to focus on the pump’s power requirement and how it....
Read MoreIn Part 1 of our Building a Pump Curve series, we discussed the parts of an unplotted pump curve. Now it's time to add some curves! In Figure 1, we've added a single head/capacity curve for a 9.5-inch diameter impeller--the largest impeller that can be used with our example pump, a Bell & Gossett e-1510 4BD. During laboratory tests...
Read MoreUnderstanding centrifugal pump curves is essential for designers and installers of hydronic HVAC and plumbing systems. These handy charts provide a wealth of information about a pump's performance capability and help us...
