  • Great Pump! By Jerrad on 12/2/2012

    Debated between the American and Japanese pumps for quite some time. American pump is slightly louder, but with dampening pads it is quieter than my skimmer/vortechs so I dont even notice it. Save yourself some cash and go American!

Does this pump deliver 1140 gph @ 13.5 feet
Question by: JOE on Mar 18, 2014 4:17:00 PM

13.5ft is the maximum head pressure, at this point the pump would stop flowing. The pump pumps at 1140gph at 0 head pressure and will decline as pressure increases. The pressure/flow curve can be found right here:
