Larger centrifugal pumps with horsepower over five are a great place to save energy in HVAC and plumbing systems. Historically, these larger pumps were typically …
Smart Variable Speed Centrifugal Pumps: Part 1 (Line Mounted)
This week and next we will talk about centrifugal pumps with the variable speed technology built into them. These pumps are called “Smart pumps.” Why …
B & G ecocirc e3 with ECM Technology (Electronically Commutated Motor)
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.
Let us take some time to answer YOUR questions…
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.
NEW PRODUCT: Energy Efficient Ecocirc 19-14 Auto & Vario Heat Circulators
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.
Large Centrifugal Inline Pump Installation
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.
Centrifugal Pump Selection for Hydronic Systems (Part 2)
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.
