Dual Speed Pump Question

[duraleigh]

Hi, Brad,

That makes sense. It seems to be a point where the pump people have decided it's not really worth it to push more water thru because the friction loss increases exponentially.

To me, it still means you could (If you were really dumb) put a 3hp pump on a 1.5 inch line and get far more than 45gpm......however, your electric bill would be larger than your house payment.

The Whisperflo is a better pump the Hayward Super pump. It also pumps more water when comparing HP to HP. The 3/4 HP Whisperflo pumps 70 GPM @ 50' of head. The 1 HP Super pump pushes 50 GPM @ 50' of head. The Whisperflo is quieter on high speed and I've always found it to be a more heavy-duty pump. The Whisperflo is meant to compete with the Hayward Northstar and the Pentair Super Flo is meant to compete with a Super Pump.

So you may WELL have made a good deal--in which case, be happy!

I am feeling much better about my purchase now!!! Hopefully I won't have trouble wiring it up!!!! I can't wait to get the pool up and running again. I just hate seeing the big black tarp!!!!!
