Northeast, Nebraska | First thing you need to do is to find out exactly what you have for water available and how deep you have to go to get it. If you aren't pumping very deep, it won't take much hp at all. Mine here in northeast nebraska are 75 hp pumping anywhere from 200 to 250' deep at 600 to 1000 gallons a minute. On our 3 phase units we have to pay a hp charge before the season even starts, then we pay the actual electricity. In reality, 3 phase equipment will use way less electricity than single phase and are cheaper than single phase equipment at the same hp. I have 5 electrics and 4 diesel power units with generators. The diesel are a little more maintenance and you can't start them with a phone from your lakehouse like you can with electrics. I don't have a lakehouse so that doesn't bother me any. If you have a shallow well under 100', you can get by with a small motor and if you aren't pumping deep and piping it far, you won't use much fuel at all and would probably be cheaper than an electric over time. Another thing to think about, if you use a phase converter from single to 3 phase, there will be some energy loss for that process so would also draw more amps and increase your electric bill. Again the difference would depend on how big of a motor you need. I would figure that out first and then ask on here again. Also, no matter what you do, don't change your mind and put a T and L pivot on. No matter how cheap you may find one or how good the pipe looks. DO NOT BUY A T AND L PIVOT! EVER! | |
