B & G ecocirc e3 with ECM Technology (Electronically Commutated Motor)

Norm Hall ECM, Inline Pumps, Monday Morning Minutes, Pumps, Selection and Specification

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.

NEW PRODUCT: Energy Efficient Ecocirc 19-14 Auto & Vario Heat Circulators

Joe Smolinski Announcements, ECM, Inline Pumps, Monday Morning Minutes, Pumps, Selection and Specification

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.

Centrifugal Pump Selection Specifying Future Conditions

Norm Hall Monday Morning Minutes, Pumps, Selection and Specification

In the last R. L. Deppmann Monday Morning Minutes, we suggested a specification that would allow a future impeller change as a means of adding some safety factor to the pump provided on your project. What happens if you want to select a pump with a present and future condition? Here is a good pump selection for a capacity of 2700 GPM at 100 foot head using a 100 HP 1750 RPM motor.
