    Yes this all helps. Thanks for everyone’s feedback. The pump manufacturer did respond to my request for a pump curve, they said call my local distributor, the distributor said he doesn’t have it and he’ll try to get it from the manufacturer, we’ll I guess we’ll see. The distributor did say that...

    What are the cons with operating a pipeline like this one in the slack line mode vs a tight line.

    The barge usually sits about 30’ farther back and the 300’ shown on the drawing doesn’t account for vertical footage, it’s probably close to 450’ to be more exact.

    Here are a couple photos the aerial picture was taken during a flood a few years back but it shows the general layout. The other are nameplate photos. I will take a couple pictures today when I get up there.

    Thanks for all the help. I have requested the pump curve from the manufacturer again. I will take photos today and try an explain the system better. I have taken voltage and current readings before to make sure the motor wasn’t running unbalanced 472VAC and 84amps on each phase. The system is...

    Slack line operation is exactly how I’m opening. Given that I’m operating this way would it be better from an efficiency standpoint to create enough back pressure on the line to operate it as a tightline, or would this cause a reduction in flow and or decrease in system efficiency. Should the...

    Sorry for not replying sooner but where I’m working there is no cell service. I inherited this pump a couple years ago and all I could get from the pump manufacturer was the gpm and a installation/service book. I may have used the term air break incorrectly, that’s what everyone around here...

    Irrigation pipe design

    I’m having to relocate my irrigation system due to a state highway project and was needing some design input. The current system consists of a 12” single stage vertical submerged turbine pump 5200gpm@40’head. It’s mounted on a barge and the pipeline consist of 500’ of 12” ips schedule 40 pvc...
