If you in the market for a wellpump, you get what you pay for. I cannot recommend grundfoss enough.

1)soft start, all electronics are in the pump and cooled by water.
2)no pump seals. The motor is in a stainless tube and the magenet coils are on the other side of it. There is no seal since there is no need for a hole in the housing. Magnets do the work.
3)stainless steel impellers. 99% of other well pumps have plastic.
4)integrated low water switch.

SQ series runs on 120vac -240vac and soft starts.
SQ-flex series runs on 30vdc - 277vac. Got 3 solar panels? Good to go.

Buy once cry once.
