High Flow Low Head Saltwater Pump
High Flow Low Head Saltwater Pump
(OP)
OK experts, here is a challenging one.
I need to pump 1200GPM at 20 TDH saltwater at 70F, on a continuous basis.
I am leaning towards a 316SS or Fiberglass type pump (at least until I hear from the pros).
Main question -- can anyone hone me in a mnaufacturer that is likely to make a suitable pump with good efficiency (say 78% or better) in the expected range.
Pump has to lift 2 to 4 feet depending on tide. Source is a salt water well, so water is pretty clear. I don't want to use any checkvalves, and it does run continiously, so once primed, it should be good to go.
Thanks to y'all, from Hawaii, PacificSteve

RE: High Flow Low Head Saltwater Pump
My first approach would have been a centrifugal pump with ejector priming but of course the efficiency is not exacly 78%. On the other hand it is something easily available and reliable and has a long service life.

We pay around $.20 per kWH at this site, one of the highest in the country.
Just as example, if this is a 20HP pump, it would cost roughly $20,000 per year to run. Over 20 years, a 10% better pumping efficiency results in a $40,000 cost savings.
Its worth making a good selection
