Fw: Need a Deep Well Pump Solution [RE-wrenches]

[Allan Sindelar]

Windy,
can you give me an estimate of the number of BP85s that I would have to
rewire/divert to run the pump? Would it be four? And expected gpm?
I'd like to try to compare pump efficiencies. The Solamotor man estimated
10A at 24VDC to run the jack pump at 1/2 gpm. That's a surprisingly high 8
watthr/gallon figure.

Thanks,
Allan
