How big of discharge line do you need for that, 4"?
The pump I was looking at in this application has a 3" discharge. The well would be 6".
JKB- What would you use a VFD for, a soft start or change flow rate?
Scott only has single phase power. The first reason is so we can take advantage of more energy efficient 3 phase motors. In the submersible pump world, there is not a huge difference, but may gain 6-8% or so. Next is as a soft starter, then to take advantage of the Affinity Laws for pumps. This is the huge part and where the most savings occur. It takes a bit of time to go thru all the possible combinations, even longer if your information sucks!!! (did I ever mention that I hate Google!)
I haven't had time to read squiggly lines and blurry PDF's today, (maybe just blurry eyes tho) but quite a few planets lined up yesterday with the 3HP and the 230S in single stage flavor. It would be nice if that would work.
Got interrupted...
Scott, measure your line voltage at your breaker panel. That would be line in, in the 200+V flavor.
How far down would the pump be?, and how far away from the well to the control?. Need to get approximate cable run length's from the VFD to the motor.
