Great info, and I was happy to learn of the Dolphin pumps, if the Vectra's don't work out. My sump is in the basement, current head height is 16 feet for me, and another reason why I'm running two. Yeah, the Iwaki seems like a power hog even as compared to other AC pumps.that had to do more with a poor choice of pump.
to test this idea:
i found an amp master 3900. (i didnt know they had one) and found the specs.
at 1.4 amps x 110 volts is 154 watts. close to the vectras but still runs ac.
ill see how they compare via performance
so at 5.5ft head pressure we get 60 gpm or 3600 gph
vectra m1
ill just give in and say it is 1600 gph x 2 @ 5ft which is 3200 gph.
a tip of the hat goes to the max head height of 20ft vs a dolphin one (13 ft). unless you are running it from your basement, i doubt itll matter.
impressive pump. ill say that. lets just hope they last or dont lose flow like their mp40s. i still think they have a bit of proving to do.
(edited to be more constructive)
also how quiet are the vectras? decibel level means a lot to us in the hobby. im assuming pretty quiet.
I have lost a power adapter, so I am keeping my eye on how these do over time. I had both power adapters stacked on top of each other and they might have overheated. Something most people with one Vectra wouldn't see, unless they also put their power adapter next to something warm.
