Bell and Gossett’s ecocirc pumps were introduced over the last few weeks. We promised to explain how the ECM technology provides more efficiency than standard induction motors. Let’s talk about the difference between a standard induction motor vs. a permanent magnet motor. With an induction motor, stator windings are arranged around the rotor so that when they’re energized, they create a rotating magnetic field. [Read more…]... READ MORE

We received a great deal of questions from last week’s Monday Morning Minutes on the Bell and Gossett Ecocirc domestic water inline pump. Two of the most asked questions were; Why is more reliable? And How does it save energy? The ECOCIRC is more reliable because there are less moving parts. Here is a brief description. [Read more…]... READ MORE

We are very pleased to announce the addition of the new ecocirc 19-14 heating circulators to our line of energy efficient products. As with the rest of the ecocirc line, this new offering also utilizes Electronically Commutated/Permanent Magnet motors, which by design are more efficient than permanent split capacitor induction motors. This technology also offers more flexibility than standard motors allowing us to add features via software logic rather than hardware that would otherwise add cost. [Read more…]... READ MORE

In our last Monday Morning Minute, we suggested using the Base Mounted Bell and Gossett series 1510 series end suction or VSX series double suction pumps when the design capacity requires over 10 HP. We do occasionally see our series 80 and series 80-SC inline pumps specified in applications up to 100 HP. Often the reason used for this application is limited floor space. Today let’s examine floor space required by these pumps. [Read more…]... READ MORE

You’ve selected the GPM (gallons per minute) flow rate and the pump head. You corrected the head for the fluid as described in the last few articles. It’s time to select a pump. Why do you select one pump over another and how do you, as the specifying engineer, make sure the submitted pump is remotely close to the one you selected. The R. L. Deppmann Monday Morning Minutes continues Pump Selection today. [Read more…]... READ MORE
