Does anyone have any experience with this motor: AO Smith / Century V-Green EMC27SQV ? I am looking at this as an energy efficient replacement for my Pentair Whisperflo. At first I was looking for a full pump like the Pentair Intelliflow or Hayward Ecostar. Replacing just the motor would save me a couple hundred bucks in equipment and installation. I know that I would be giving up something in not getting the whole pump.
Unfortunately I cannot find everything that I need to know about the V-Green, like how does it achieve its efficiency and how that efficiency and life span compares to the the other two pumps.
The V-Green is a variable speed pump (with a remote mountable control panel) so it gets much of its efficiency from that variable speed. The others are permanent magnet motors which increases efficiency and life span. I just can't find that information about the V-Green.
