Twice the flow of the 750 series at eleven foot of head. May have a lower maximum nominnal load flow but handles head better. This one will do 3300 gph for about 2.3 amps. At eleven foot of head we see about 2250 gph.
Remember to buy a leaf trap if you need one. This pump does about 4200 gph for about one and a half amp. Wow! Three year warranted unless submerged or it chews up a rock.
Sequence Primer 3700 gph @ 2.76 Amps - 3700 gph at less than 3 amps! Wow! Self priming makes this one a winner!
